Here is what that means in practice.* The Bureau produces reader-focused reference material on Nexus Market, one of the currently active Tor storefronts. The method is straightforward. Every claim in every published piece is traceable to a specific observation, signed announcement or protocol document, and every editor working on the material is bound by the same three rules. ## The three rules Rule one. Nothing gets published that we cannot verify ourselves. If a mirror address appears on a page, an editor has verified it against the operator PGP signature within the past thirty days. If a piece of storefront behaviour is described, an editor has observed it directly in the past ninety days. Rule two. No affiliation. The Bureau does not run Nexus. The Bureau is not paid by anyone connected to Nexus. The Bureau does not accept sponsored content, affiliate links or paid placements from vendors on Nexus. When we recommend a wallet, a browser setting or a workflow, it is because we use it ourselves, not because someone paid for the placement. Rule three. Every published piece has an editor byline (as Editor, since the Bureau is not a personal brand) and a last-revised date. When we get something wrong and someone tells us, we fix it and add a correction line at the bottom. We do not silently rewrite history. ## Sources we treat as primary Operator-signed rotation announcements on the pinned Dread thread. The /pgp path on any current Nexus mirror. Direct observation of storefront behaviour by editors who use the market as ordinary buyers. Reader mail asking about specific problems. ## Sources we treat as secondary Third-party directory listings, forum posts, Telegram channels and search-engine snippets. These get cross-checked before anything they claim ends up on a page. Roughly two thirds of what circulates in secondary sources turns out to be wrong or out of date, which is why they never make it in unchecked. ## Update cadence Reports get a light revision every ninety days and a full revision every year. Case studies are published once and revised only if we discover a factual error. Dossiers are revised when the underlying mechanism changes. Notes are point-in-time observations and do not get updated, they just get superseded by newer notes if the topic recurs. The Library is revised as needed. ## How to reach us Through the message system on any current Nexus mirror, addressed to the Editor account. Corrections in prose welcome. Tips on interesting operational events welcome. Sponsorship offers not welcome. --- ## Editorial policy in full *The rules the Bureau publishes under, spelled out.* This is the full editorial policy of the Nexus Market Bureau. It exists so that readers who come across the Bureau for the first time can decide, on the basis of stated rules, whether the material here is worth their trust. Everything below is enforced by the editors and reviewed twice a year. ## What we cover The operational architecture of Nexus Market: mirror rotation, escrow, coin support, verification workflow, vendor system, captcha behaviour, anti-DDoS queue. Editorial coverage of storefront events that materially affect a buyer's experience: rotations, key notes, feature changes, coordinated phishing waves. Reference material a first-time visitor to the storefront needs to reach the login page without landing on a clone. ## What we refuse to cover Individual vendors. We do not recommend, review, rank or otherwise editorialise about specific sellers on the storefront. That is the buyer's job to work out from the vendor page. Prices, product availability, category-specific listings. Not our beat. Whether to use the storefront at all. Whether Nexus Market activity is legal in your jurisdiction is your decision, not ours. We report on the storefront that exists; we do not advocate for its use. ## Sponsorship policy The Bureau does not accept sponsored posts, affiliate links, paid placements, banner ads, native advertising or any other form of paid content. If a vendor offers to pay for coverage, the answer is no. If a competing storefront offers to pay for coverage of Nexus that would benefit them, the answer is no. If a wallet vendor offers to pay for a recommendation, the answer is no. The Bureau has no operational relationship with the Nexus operator. If the operator asked us to change anything on the site, the request itself would be documented on the notes page, and our answer would still be no. ## Correction policy When we get something wrong, we fix the error and add a correction line at the bottom of the piece with the date and a short description of what changed. We do not silently edit history. Corrections come in through the message system on any Nexus mirror. ## Anonymity policy Editors are anonymous. All bylines read Editor. We do not publish individual editor identities because the value of the Bureau is the material itself, not the reputation of the people producing it. Nothing here should be trusted on the strength of a name. ## Publication cadence Reports: one every four to eight weeks. Case studies: one every quarter. Dossiers: revised when the mechanism changes. Notes: as topics arise, several per month in busy periods, zero in quiet ones. Library: continuous. ## Language English. Plain, direct, unadorned. No marketing tone, no salesmanship. If a piece feels dry, that is the intent. --- ## The editor group, anonymous by policy *Why the Bureau bylines all read Editor, and why that matters for how you read the material here.* Every piece the Bureau publishes is signed Editor. There are no individual bylines, no author bios, no photos on the site. This is a deliberate editorial choice, and it is worth explaining what the reader gets under this model and what the reader gives up. ## Why anonymity Because the value of the material is the material. A reader who trusts a Bureau report because a specific person wrote it is trusting the person, not the process. The Bureau prefers readers who trust the process. When a report says an operator PGP key has held for two years, that claim is either true (checkable against the signed rotation history) or not. Who wrote the sentence does not change the truth-value of the sentence. Anonymity also protects the editors. Everyone who works on Bureau material has a personal life outside it. A named editor becomes a target for anyone who wants to pressure the Bureau into publishing or unpublishing something. Anonymous editors do not. ## What the reader gets Editorial output that stands or falls on its own. Every claim checkable. Every date verifiable against operator posts. No personality-driven narrative colouring the material one way or another. ## What the reader gives up The ability to build a track record on individual editors. If one editor writes ninety percent of the reports, you cannot tell. If a specific editor produces material you find unusually good, you cannot follow their work specifically. This is a real cost. The Bureau accepts it in exchange for the anonymity benefit. ## Practical implication Read the material sceptically. Not because Bureau editors are unreliable, but because that is the right posture toward any anonymous source on any subject. Cross-check factual claims against the sources the Bureau cites. Verify signed rotations against your own keyring rather than trusting our verification. The Bureau's method is designed to make cross-checking easy. Use it. --- ## Contact the Bureau *Where to send corrections, tips, and questions the Library FAQ does not answer.* The Bureau reads reader mail through the on-storefront message system on any current Nexus Market mirror. Address the Editor account. This is the only channel we monitor for correspondence. ## What we respond to Corrections to published material with specific citations of what is wrong and evidence for the correct version. Tips on operational events that would fit under Reports, Case Studies or Notes. Questions the Library FAQ does not answer. Reader mail patterns worth summarising in a future note. ## What we do not respond to Sponsorship offers. Requests to review specific vendors. Requests to unpublish material about specific vendors. Requests to add affiliate links. Legal threats (if you have a legitimate legal claim, send it through channels that assume anonymous editors, because that is what we are). ## Response times Corrections: within 72 hours if the correction is well-evidenced. Tips: reviewed within a week, may or may not turn into a published piece depending on newsworthiness. Questions: pointed to Library first, answered if not covered. ## PGP All Bureau correspondence over the message system is on top of the storefront's own encryption. For anything sensitive on the reader's side (proof of identity you do not want on the storefront database), attach a PGP-encrypted block to the Editor key, published on the About section. ## What the Bureau does not do Reply on chat platforms. Take DMs on Reddit or forums. Answer questions posted publicly on Dread threads (we may read, we do not reply on those channels). All correspondence goes through the storefront message system, period. --- # Section: Reports ## The Nexus mirror set, 2026 report *A structural report on the current mirror rotation, its size, its logic, its recent history.* At the time of writing, Nexus Market publishes several onion mirrors in a single operator-signed rotation. Every mirror on the list resolves to the same backend. Account, balance, orders and messages appear identically on any of them. Choice of mirror is a matter of routing speed on your Tor circuit, not a matter of storefront identity. ## Why more than one mirror A single onion address is a single point of routing failure. Even a well-provisioned hidden service can be unreachable for a specific user because of a bad Tor guard, a hostile ISP, a network outage between the reader's ISP and the first Tor relay, or a temporary hidden-service-descriptor stale-out in the Tor consensus. Any one of these is enough to make a reader believe the market is down when in fact the market is fine and the reader's circuit is bad. The mirror rotation solves this cheaply. When the primary is not resolving on your circuit at the moment, you copy the second address from the list, paste, and the storefront comes up. The reader loses maybe forty seconds of scrolling through mirrors. The alternative, in the single-mirror model, is that the reader loses the session entirely. ## Why not many more mirrors More mirrors do not add proportional value once you cross the small-set threshold. Three addresses cover most single-outage scenarios. Additional addresses buy you more coverage in exotic multi-failure scenarios, but at a cost: more addresses is more surface for phishing clones that try to blend into the operator publication, more addresses is more work for editors verifying the signed rotation, and more addresses is more entries a reader has to eyeball against the captcha URL match. The trade-off point sits at roughly three to six mirrors depending on the operator's own load model. Nexus has been at three lately. ## Rotation cadence in 2026 Signed rotations from the Nexus operator have arrived roughly every four to eight weeks through 2026. Every rotation swaps one address in the published set for a new one, or (occasionally) introduces a new address without retiring an old one, briefly showing the reader an extended set for a week or two. Retirements do not happen without a signed announcement. ## Latency and mirror age Older mirrors, in general, are faster. They have accumulated Tor descriptor consensus, they route through known-good guards, and the hidden service directory nodes have their information cached. Freshly rotated mirrors sometimes bounce for the first week while descriptors propagate. Reader latency observations across late spring 2026 showed the primary running around 140 to 200 milliseconds median, the older backups at 150 to 220, and the newest addition after each rotation at 200 to 400 for the first several days. ## What a rotation looks like from the reader side The reader sees a signed post on the pinned Dread thread announcing the new address. The reader verifies the PGP signature (see the dossier on the operator key). The reader updates the bookmark. The reader keeps using the storefront exactly as before, because the address change is the only thing that changed. ## What a rotation looks like from the Bureau side Editors verify the signed post against the operator key on file. If the signature is good, the new address is added to the Library mirror list before the retired address is removed. If the signature is bad, nothing happens and we log the failed post for later reference. Editors have never had to publish a bad-signature warning yet under the current operator key. That fact itself is a data point. --- ## Escrow model, 2 of 3 multisig on Nexus *The escrow mechanism explained end to end, plus what it covers and what it does not.* Every deposit on Nexus Market settles through a 2 of 3 multisig contract. Three private keys are generated per order, one held by the buyer, one held by the vendor, one held by the market platform. Any two of the three, in combination, can move the coin out of escrow. The third is not needed for a healthy order. ## Why 2 of 3 The design goal is to remove the market operator as a custodian while keeping a tiebreaker for disputes. In a straight 2 of 2 between buyer and vendor, either side going offline would freeze the coin indefinitely. Adding a third key held by the platform gives the reader a dispute path without giving the platform custody. The market cannot walk with the coin because it holds one out of three keys, and any single key on its own can move nothing. ## The happy path Buyer deposits into the multisig address printed at checkout. Vendor ships. Buyer marks the order received. Buyer and vendor sign the release. Coin moves to the vendor address. Platform key never moves. ## The dispute path Either party opens a dispute through the storefront. The moderator reads both sides of the message thread, requests any missing evidence, checks the vendor dispute history, and judges. The moderator then cosigns with whichever side they judged correct. That signature is the second of the two needed. Coin releases accordingly. ## The refund path When the moderator decides the buyer is owed a refund, the moderator cosigns with the buyer key to move the coin to a refund address the buyer specifies at that stage. The vendor is not required for the refund to settle. This is the second most common failure mode after seller fraud, and it is exactly the mode a 2 of 3 model closes cleanly. ## Edge cases Buyer loses their key mid-order. Buyer becomes one of two remaining signers, dispute path resolves the deadlock, moderator cosigns with the vendor to complete the order or with a refund address depending on the moderator judgement. Vendor loses their key mid-order. Symmetric case. Buyer opens the dispute, moderator cosigns with the buyer to either release the coin to the vendor or refund the buyer. Platform loses moderator availability during a dispute window. This has not been observed on Nexus. In theory the coin would remain in the multisig address indefinitely until a moderator returned, since neither party has enough signatures alone. ## What the model fixes The classic exit-scam pattern. The market operator cannot wake up one morning, move the entire pool of buyer deposits, and vanish. Every deposit sits in its own multisig contract, and the operator holds one key per contract, never enough to release. This closes the single largest historical failure mode of Tor storefronts. ## What the model does not fix Seller fraud. A vendor can still ship a rock instead of the item. Multisig only guarantees the platform cannot steal, it does not guarantee the vendor is honest. Moderator error or bias. If a moderator cosigns with the wrong side of a dispute, the correct-side party is out. Reader defence here is choosing vendors with clean dispute histories in the first place. Buyer error. Buyer signs a release without receiving the item (finalising early, or FE) and then no path exists to reverse the release. The Bureau discourages FE in every context. See the note on FE for details. ## Practical read for a first-time buyer Multisig closes the biggest historical risk but does not remove the human risks. Choose vendors carefully, do not finalise early, keep escrow balance sized to the current order rather than the year of orders, and use the message system for anything a dispute might turn on. --- ## PGP verification workflow, from key to signature *The full verification workflow a reader should run once per operator key and once per rotation.* PGP verification is the mechanism that turns a random-looking onion address into a trustworthy one. The workflow is boring and takes about a minute per rotation. It is worth reading in full once, then referring back to only when something goes wrong. ## What verification proves A PGP signature over a message proves two things simultaneously. First, that the message was signed by the private key corresponding to the public key you have. Second, that the message has not been altered since signing. If a signed rotation announcement from the Nexus operator verifies against the operator public key you already have on your keyring, the address inside is genuinely from the operator and has not been tampered with. ## Getting the operator key, first time The operator public key is published on the pinned Dread profile and on the /pgp path of every current Nexus mirror. Fetch it once, from at least two independent sources, and cross-check the fingerprint. If the two fingerprints agree, import the key and never re-fetch. The whole point of the model is that trust rests on the first key you got, not on repeated fetches. ## Import gpg --import nexus.asc One command. The output confirms the import and shows the key ID. Save the fingerprint somewhere durable (a paper note, an encrypted local file), in case you switch machines and need to re-verify that the operator key on the new machine is the same one. ## Verify a rotation Save the whole signed message, including the envelope headers, into a text file. Do not strip the blank line between the hash header and the message body. Do not add anything at the end. The signature covers every byte and a single extra space breaks the check. gpg --verify rotation.txt Success looks like a line beginning with gpg: Good signature from followed by the operator's user ID. A second line usually reads WARNING: This key is not certified with a trusted signature. That warning is normal and expected. It means you have not personally signed the operator key with your own key, which is fine. What matters is the Good signature line above. ## Common error messages BAD signature. The file has been altered after signing. Do not trust the address inside the message. Report the bad post to the pinned Dread thread so other readers see the warning. Can't check signature: No public key. The operator key is not on your keyring yet. Import it first. Signature made ... using RSA key ID ... followed by a key ID you do not recognise. The message was signed by a different key. Do not import that key. Do not use the address inside. Signature made ... (expired). The signing key has expired. This is worth investigating: the operator either has to publish a new key under the outgoing one, or has been compromised. Do not use the address inside until the situation clarifies. ## Kleopatra path (Windows) Kleopatra ships with Gpg4win. The same operator public key file can be imported through File → Import. The same signed rotation can be saved to rotation.txt and verified through right-click → More GpgEX options → Verify. A window pops up with the result. Same principle as gpg on the command line, different button. If you prefer graphical interfaces, this is the path. ## Handling a key rotation If the operator rotates the signing key itself (as opposed to rotating a mirror address), the change is announced in a signed message under the outgoing key, with a copy of the new public key attached and cross-signed by the outgoing one. The reader verifies the announcement against the outgoing key, checks the new key fingerprint against multiple sources, imports the new key, and updates the trust anchor. Key rotations are supposed to be rare. Nexus has not rotated the operator signing key since the storefront opened. If you see a key-rotation post that does not carry a valid signature from the outgoing key, do not import the new key. ## Why bother with all this Because phishing clones cannot fake a valid signature. Every other check on a mirror address is defeatable by a determined attacker with time and infrastructure. The PGP check is the only anchor that a phishing clone cannot spoof without the operator's private key. That is why we run it. --- ## The Nexus vendor system, structural report *How the vendor system is organised, how new vendors get on, how buyers read the numbers.* The vendor system on Nexus Market is what most buyers actually interact with day to day. This report walks through the structural pieces, how a new vendor gets on, what the numbers on a vendor page mean, and how a buyer reads them. ## Getting on A new vendor posts a refundable bond in coin before the first listing goes live. The bond is calibrated by the operator and adjusted periodically as market conditions change. Its size is meaningful enough that a scam-bait vendor considering a single open-take-vanish sequence has to weigh the bond loss against the expected haul. In practice this filters out most casual scam attempts because the expected haul on a single new-vendor account is usually less than the bond. The bond is returned after a clean thirty-day probation period during which the vendor completes at least a handful of orders with no unresolved disputes. Bonds are not withheld indefinitely, they are returned on a schedule. ## What appears on a vendor page Vendor name (and any past aliases if the vendor migrated from another storefront), order count total, disputed order count, finalisation ratio, average shipping time, published PGP public key, current active listings, and a review feed sorted by date. This is the standard layout on any current Nexus mirror. ## Reading the dispute ratio Dispute count divided by total orders. A vendor with 400 total orders and 3 disputes runs at 0.75 percent, which is healthy. A vendor with 400 orders and 40 disputes runs at 10 percent, which is not. The Bureau's rule of thumb: below 5 percent is healthy, 5 to 10 percent is a yellow flag (read recent reviews for what is happening), above 10 percent is a red flag (skip). The exception to the last rule is a vendor whose product category naturally produces more disputes (fragile packaging, ambiguous quality metrics, complex configuration), where a higher baseline is normal. But even for those categories, above 15 percent is uniformly a bad sign. ## Reading the finalisation ratio Orders that closed cleanly divided by all completed orders. Cleanly means both parties signed the release without a dispute. A healthy vendor sits above 95 percent. Below 90 percent means one in ten orders required a moderator to arbitrate, which is worth investigating. ## Reading recent reviews Scroll to the last twenty reviews. Ignore the lifetime average, it hides recent decline. If the last twenty are noticeably worse than the vendor's older reviews, the vendor is going through something. Read the review text, not just the star rating. Look for consistent complaint patterns (packaging quality, shipping delays, product weight or purity). ## The PGP key requirement Every vendor is required to publish a PGP public key at registration. This is not a legal requirement, it is an operational one enforced by the storefront. Buyers are expected to encrypt shipping details to the vendor key before sending anything sensitive through the on-storefront message system. Even though the message system is itself encrypted by the storefront, layering a personal PGP key over the top means the storefront database sees only ciphertext for the address fields. ## The average shipping time Calculated from the last thirty days of successfully completed orders. Vendors with a low average that suddenly spikes are worth extra caution: something changed on their side (maybe they got busier, maybe they lost their supply source, maybe they are dragging out shipments to buy time). A vendor with a naturally slow shipping baseline (some international shipping windows are inherently long) is not automatically worse than a fast one, if the reviews say the vendor communicates through the wait. ## Read time before order time Two minutes on a vendor page saves a week of dispute mail. The Bureau's standing recommendation for a first order with any vendor: read the dispute ratio, read the finalisation ratio, read the last twenty reviews. Two minutes total. If anything you see in those two minutes makes you pause, choose a different vendor. That is the whole vendor-selection workflow. --- ## Coin economics, Monero, Bitcoin, Litecoin on Nexus *Which coin the storefront prefers and why, plus the wallet software that pairs well with each.* Nexus Market accepts Monero, Bitcoin and Litecoin. The wallet panel defaults to Monero for new buyer accounts, and the operator has never made a secret of preferring Monero for reasons of chain privacy. This report walks through the practical trade-offs per coin, the wallet software that pairs well with each, and how a first-time buyer sources coin without a KYC exchange in the middle. ## Monero, the default Monero transactions hide the sender, the receiver and the amount by default. Not opt-in privacy that you have to configure, but on-by-default privacy at the protocol level. From the market side, the operator sees only that a deposit landed at your account. From the chain side, an observer sees the transaction happened but cannot see who sent it, who received it, or how much. This is the whole reason Nexus defaults to Monero. Every other coin leaves a permanent public trace from your source wallet to the market deposit address. Monero does not, and that difference is worth more than any speed or fee advantage another coin might offer. ## Bitcoin, the fallback Bitcoin works for every order but leaves the strongest public trace of any coin the storefront accepts. Every transaction is visible forever to anyone who cares to look, and modern chain analysis can trace flows across dozens of addresses within seconds. Use Bitcoin only for legacy balances (coin you already hold), or for vendors who price in BTC for category reasons. If you use Bitcoin, route through a fresh wallet or a Monero swap before depositing. Sending straight from a KYC exchange withdrawal to a market deposit address ties your ID to the market account through the exchange records. This is one of the most common privacy mistakes on Tor storefronts. ## Litecoin, the small-order coin Litecoin confirmations arrive in under three minutes on average, four times faster than Bitcoin. Fees run a few cents versus a dollar or more on Bitcoin at typical congestion. Litecoin uses the same public-chain model as Bitcoin, so the privacy story is identical (bad), but the speed and cost story is better for orders below the size where Monero is worth the setup effort. ## Wallet software Monero: Feather Wallet on desktop (lightweight, no full node required, actively maintained), Cake Wallet on mobile, Monero GUI if you want to run your own node for maximum privacy. Bitcoin: Sparrow for privacy-aware Bitcoin, coin control support, works with hardware wallets. Electrum for lightweight use if you do not need coin control. Litecoin: Electrum-LTC on desktop. Same interface family as Electrum for Bitcoin. Do not use custodial exchange wallets for market deposits. Do not use browser-based hot wallets. Both are common sources of buyer fund loss. ## Non-KYC funding, if you are starting fresh Three paths worth knowing about in 2026: - RoboSats over Lightning. Peer-to-peer Bitcoin trading with a random robot avatar as your identity. Fees around 0.2 percent. Payment methods range from Revolut and Wise to cash by mail. Good for small-to-medium amounts. - Cake Wallet built-in swap. Buy Bitcoin however you already do, send to Cake Wallet, swap for Monero inside the wallet through one of the integrated providers. The provider sees the incoming BTC address and the outgoing XMR address but not your identity. - Bisq. Older desktop peer-to-peer market with more payment methods (SEPA, national bank transfers, cash in person). Requires a security bond, so you need some Bitcoin to buy some. More friction but more flexibility. ## Practical read for a first-time buyer If you have no coin at all: RoboSats to get a little Bitcoin, swap to Monero inside Cake Wallet, deposit Monero to your Nexus wallet. Total setup time is about ninety minutes the first time. If you already hold Bitcoin from KYC: send to a fresh Sparrow wallet, swap to Monero, deposit. Adds two hops between your KYC record and the market. If you hold Monero already: deposit directly. Nothing else to do. --- ## Phishing defence, the reader-side workflow that works *What actually protects a Nexus Market user against phishing clones, in the order those defences run.* Phishing is the single largest historical cause of buyer account loss on Nexus Market and every other serious Tor storefront. Not exchange failures, not exit scams, not law enforcement seizures. Phishing. This report walks through the defence workflow that actually protects buyers, in the order those defences run. ## Layer one: bookmark hygiene The first line of defence is not verifying anything about the address you are about to visit, it is having a trusted source for that address in the first place. Bookmark the mirror reference page inside Tor Browser. Never type an onion from memory. Never click a link to a Nexus mirror from a search-engine result, a chat message, a forum banner, or a directory site you have not personally vetted. If the address does not come from either your own bookmark or a signed rotation announcement you verified yourself, treat it as untrusted. Most reader account loss traces back to this step failing. The reader trusted a link from somewhere, and the link went to a phishing clone. Everything else downstream (captcha, credentials, deposit) followed. ## Layer two: PGP verification per rotation When the operator publishes a signed rotation, verify it. Once per rotation, not once per session. This is what turns a set of addresses on a page into a set of addresses you can trust. See the report on PGP verification workflow for the step-by-step. Verifying once per rotation catches the class of clones that try to publish a fake rotation. They cannot sign under the operator key, so the fake rotation will fail your PGP check, and the addresses inside are worthless. ## Layer three: captcha URL match per session Every session, before typing the password, read the small text at the bottom of the login captcha image. Compare it against your URL bar. Match wins. Mismatch means phishing clone. This defence exists because bookmark rot is real. A bookmark you saved months ago may point at an address that has since been rotated out. If a phishing clone happens to notice the retirement, they can spin up a clone on a lookalike domain and hope you click the stale bookmark. The captcha check catches this pattern on the first attempt. ## Real-world clone patterns Bureau observation across the past year of clone attempts against Nexus: Domain squats. Clones on clearnet domains that look close to a Nexus address (like nexus-market-onion.xyz). These target readers who search for Nexus in a clearnet search engine. Defence: never search for Nexus on clearnet, ever. Nexus is a Tor storefront, it does not have a clearnet presence. Prefix-collision onions. Onion addresses that match the first 4-8 characters of a real Nexus address. These target readers who eyeball only the beginning of the string. Defence: full letter-for-letter comparison of the entire 56 characters. Stale-address hijacks. A rotated-out real address gets registered by a phishing clone shortly after the operator retires it, and the clone serves a login page on the address. Some readers with stale bookmarks land on it. Defence: keep bookmarks against the current signed rotation, not against addresses you memorised. Search-engine sponsored results. A clone runs paid search ads for Nexus-related queries. Defence: same as domain squats, never search for Nexus on clearnet. ## What phishing clones do after credential capture They wait. The clone captures your username, password and any mnemonic seed you type in a panic. It does not immediately steal your account, because the clone infrastructure needs your login credentials to actually work on the real Nexus login. So the clone stores them, and at some point the operator (or their downstream buyer of stolen credentials) logs into your real account through the real storefront, and drains what is drainable. The drain window is usually within 24-48 hours of capture. If you realise you were phished, immediately log into the real Nexus, change your password, and withdraw any wallet balance to a fresh address you control. ## What phishing clones cannot do They cannot fake a signed rotation. They cannot fake the captcha URL match against the real address. They cannot compromise the operator PGP key. Any single one of the three defence layers, run correctly, catches the median phishing attempt. --- ## DDoS defence architecture, queue and mirror scaling *What happens when Nexus is under coordinated network pressure, and why the queue is doing its job.* Coordinated network pressure against Tor hidden services is a recurring event, and Nexus Market has been hit several times across its operational history. This report walks through what happens architecturally when Nexus is under pressure and what the reader sees. ## The anti-DDoS queue in detail Every mirror sits behind a queue page. When a reader arrives on the login URL, they see the queue counter for 20 to 60 seconds under typical load. When network pressure spikes, the counter can extend to several minutes. The queue is not just a delay. It is a rate-limiter that filters requests by holding them briefly and then admitting them serially to the captcha stage. This means a bot spinning up thousands of concurrent connections has to wait on each one, which converts a mass credential-stuffing attempt into a slow trickle that the storefront's login handler can absorb. ## Multiple mirror addresses as a scaling mechanism Under coordinated pressure, one address gets the brunt of the attack. Other mirrors on the rotation typically stay reachable because attackers concentrate resources on the primary. This is a soft form of load balancing: readers who cannot get through on the primary switch to backup addresses and complete their sessions there. This is why the mirror rotation matters even for buyers who never touch a backup during normal times. The backups exist for the days when the primary is under load and their existence is the difference between a session that completes and a session that does not. ## Observed patterns in past pressure events Bureau editors have observed several coordinated DDoS windows against Nexus, spanning from a few hours to a few days. Common patterns: Weekend timing. Attackers prefer weekends when operator response time is slower and reader activity is higher. The Bureau has observed disproportionate concentration in the Friday-to-Sunday window. Queue extension. Peak queue times during the summer 2026 event reached about four minutes on the primary. Backups held at 60-90 seconds during the same window. No captcha degradation. Under all observed pressure so far, the captcha continued to render correctly, the address remained embedded, and the login handler eventually succeeded. No reader has reported a completely inaccessible storefront across a pressure event lasting less than 48 hours. ## What the reader should do under pressure First: recognise you are under pressure rather than misconfigured. If the queue counter is decrementing, the storefront is working, it is just slow. Wait it out. Second: try a different mirror if the primary is stalling for more than two minutes. Do not immediately assume the market is down. Third: check for a signed operator statement. Under significant pressure the operator sometimes posts a note acknowledging the wave, which the Bureau will link from the security notes section. Fourth: use New Identity in Tor Browser to get a different circuit. Sometimes the slowness is your Tor circuit, not the mirror. ## What the reader should not do under pressure Retype the address from memory. If the current session is under pressure, the phishing risk is elevated too, and typing from memory is more likely to land on a lookalike. Trust a chat message claiming to be from Nexus support telling you where to log in instead. Nexus support does not run chat channels. Skip the captcha check. Pressure is when the captcha check matters most, because attackers know readers are frustrated and looking for shortcuts. --- ## Reader threat model, what the Bureau assumes *The assumptions the Bureau makes about the reader environment, and why they matter for the material here.* Every piece of advice on this site is calibrated for a specific reader threat model. This report spells out that model so you know when Bureau advice applies to you and when your situation calls for something different. ## The default reader The Bureau assumes the default reader is an adult using Nexus Market for personal reasons in a jurisdiction where such use may or may not be legal. The reader has access to Tor Browser and understands enough about the internet to install it correctly. The reader is not a security professional, not a journalist under threat, not a state-level target. The reader wants to reach the storefront, transact, and leave without their real identity being linked to their market account or their host operating system being compromised. ## Adversaries we assume Phishing operators. The most common adversary. Their goal is to capture credentials and drain wallets. Defence covered in the phishing report. Casual chain surveillance. Someone with public chain-analysis tools who might link a market deposit address to a KYC exchange withdrawal. Defence: Monero, or Bitcoin routed through a fresh wallet or swap first. Storefront database seizure. Historical pattern where a market operator's infrastructure is seized and the reader database is examined. Defence: no reused identifiers, no long-term wallet balance, PGP encryption over anything sensitive. Compromised Tor Browser install. Reader downloaded Tor Browser from a fake source, or installed extensions that fingerprint them uniquely. Defence: torproject.org only, no extensions, security slider on Safest. ## Adversaries we do not model State-level targeted attack. If a national security agency specifically wants your identity linked to your Nexus account, the defences described here are not sufficient. Do not use the Bureau's material as a threat model for that adversary. Consult specialists. Physical compromise. If someone with physical access to your device is your adversary, the compromise is already complete before you open Tor Browser. Defences in that scenario are hardware-encrypted disks, boot-from-USB systems like Tails, and habits well outside the scope of this Bureau. Insider Nexus operator. We assume the operator is not actively adversarial. If the operator is compromised or turns adversarial, the 2 of 3 multisig closes one class of attacks (wallet drainage), but the reader database is still at risk. ## Trade-offs we accept Convenience versus privacy. The Bureau consistently recommends the more private option (Monero over Bitcoin, PGP over plaintext, Tor Browser over a regular browser with a VPN). This costs the reader minutes of setup and workflow friction. We think the trade is worth it. Not everyone will. Operational sophistication versus reader onboarding cost. The strongest defences (Tails on USB, dedicated hardware, own-node Monero) are more effort than most readers will accept. The Bureau recommends the strongest defences a typical reader will actually implement, not the theoretically strongest defences that no one implements. ## When to escalate beyond Bureau recommendations If your threat model includes a state-level adversary, use Tails on dedicated hardware, never touch the storefront from your host operating system, and consult a security specialist for anything beyond that. If your threat model includes physical compromise of your device, do not use the storefront at all from that device. If your threat model includes needing plausible deniability about ever having accessed the storefront, use Tails, do not enable persistent storage, and reboot after every session. --- ## Mobile Tor Browser for Nexus, notes and caveats *Using Tor Browser for Android against Nexus, what works, what does not, when to prefer desktop.* Tor Browser for Android exists and works against Nexus Market, but there are meaningful differences from the desktop experience. This report walks through what changes on mobile and when the reader should stick with desktop. ## What works on mobile The login flow works. The anti-DDoS queue renders. The captcha renders correctly with the embedded address visible. Registration, deposit, order placement, message system, dispute opening, finalisation all work. ## What is more friction on mobile Copying the onion address is fiddlier because mobile browsers do not always handle 56-character string selection cleanly. The Bureau recommends using long-press to select the full string carefully rather than trying to double-tap. Tor Browser Android does not have the same security slider UI as desktop. The equivalent setting is in the security preferences, and the reader should still set it to Safest. It matters equally on mobile. Fingerprint uniqueness on mobile is a bigger problem than on desktop because there are fewer mobile Tor Browser users, and mobile screen sizes vary more distinctly than desktop windows do. This reduces the anonymity set. Mobile is fine for reading but the Bureau prefers desktop for anything involving credentials. ## Wallet on mobile Cake Wallet is the natural mobile Monero wallet. It works well, is well-maintained, and integrates cleanly with the Nexus deposit flow if the reader is comfortable copying strings between apps. Bitcoin on mobile is a mixed story. The Bureau recommends against using mobile hot wallets for Bitcoin deposits to a market. If you use Bitcoin, do it from desktop with Sparrow or Electrum. ## When mobile is fine Reading the mirror list. Reading Bureau reports. Checking the current signed rotation. Passive activities that do not involve typing credentials. ## When desktop is worth switching to Registration (mnemonic seed handling is easier on desktop). First login (captcha match is easier to read carefully). PGP verification (gpg or Kleopatra are desktop tools). Deposit signing (wallet software is more capable on desktop). Any high-value transaction. --- # Section: Case studies ## Nexus Market launch, January 2024 *A case study on the storefront opening: one signed post, one mirror, one PGP key, and the two years of quiet reliability that followed.* Nexus Market opened in January 2024 with a single signed announcement on the pinned Dread thread. One primary onion address. One PGP public key attached. One paragraph of launch text. Two years later, the operator PGP key has not changed, the escrow model has not changed, and the storefront still runs. That combination of durability and quiet is uncommon on Tor and worth a full case study. ## The launch post The original post was short. Three paragraphs describing the escrow model (2 of 3 multisig from day one), the accepted coins (Bitcoin and Monero at launch, Litecoin added later), and the anti-DDoS approach (queue in front of the login, with the operator noting they had watched competitors get credential-stuffed and wanted to make that harder). The attached PGP block gave the operator public key with a fingerprint that has been stable since. ## Why launch quiet Loud market launches usually fail faster than quiet ones. The louder the launch, the more attention from law enforcement, from competing operators looking to identify weaknesses, and from phishing operators looking to spin up clone domains. A quiet launch reads as a signal that the operator is not trying to convert quickly. This has consistently correlated with longer market lifetimes. The Nexus launch was as quiet as launches get. One post. No trumpet. No affiliate scheme. No launch discount. The whole message was: here is the address, here is the key, here is how the escrow works, do not use us if you have not read this. ## The first six months Through spring 2024, Nexus added its second mirror, then its third. Both additions were announced in signed posts under the same operator key. The set stabilised around three mirrors in the current era. Reader traffic grew steadily but not dramatically. Dispute counts stayed low relative to competitors, largely because the multisig-by-default design meant the platform never held custody of buyer deposits, which removed the largest structural cause of disputes on other storefronts. ## The first year in review By late 2024, Nexus had roughly a thousand active vendors and had processed enough orders to make chain-analysis observers notice the volume flowing through its multisig addresses. No exit-scam attempts. No security incidents worth publishing under advisory. The operator posted a quiet one-year note thanking readers for staying boring, which was the correct thing to thank them for. ## The second year Through 2025, the storefront expanded its vendor pool, tightened its bond schedule to filter more scam-bait accounts, and refined the anti-DDoS queue after observing a coordinated pressure event in the summer. Litecoin was added to the wallet panel for smaller-order buyers. Captcha was reworked to embed the current mirror address inside the image itself, which is the phishing check now standard across serious Tor storefronts. ## What the two-year survival demonstrates Not that the operator is good (unknown, and irrelevant). Not that the storefront is popular (moderately, but that varies week to week). What it demonstrates is that a market with 2 of 3 multisig from day one, a stable PGP-signed rotation, and a boring operator style survives longer than the alternatives. The list of Tor markets that opened around the same time as Nexus and are no longer running is long. Most exited with the pool. A few were seized. A few just went dark without explanation. The ones that made it to two years are the ones that did not concentrate custody in the operator's hands and did not run a launch that attracted the wrong kind of attention. ## What could still happen Nexus could exit tomorrow. That would be surprising given the multisig model, but nothing prevents it. Nexus could be seized in a coordinated law-enforcement operation. That would be surprising given the operational security signals the operator has demonstrated, but nothing prevents it. Nexus could quietly go dark without explanation. That has happened to other long-running storefronts. The correct read for a buyer is: do not treat any Tor storefront as permanent. Keep the wallet balance sized to the current order, not to a year of orders. Assume everything you have on the market will be gone tomorrow, and structure your use of the storefront around that assumption. The two years of quiet on Nexus are not a promise, they are a demonstration. --- ## Vendor taxonomy, how categories drift over time *A case study on the drift of vendor categories on Nexus across the last two years.* Vendor categories on Nexus Market have drifted noticeably across the storefront's two years of operation. Some categories that were large at launch have consolidated into fewer active vendors. Others that were niche have fragmented into subcategories. A handful of categories have vanished entirely. A few new ones have emerged. This case study walks through the pattern. ## What has consolidated The digital goods category, which had roughly two dozen active sellers at launch, now has around eight. The consolidation is not because demand dropped, but because the surviving vendors ran cleaner operations and accumulated better reputation faster than newcomers could enter. Bond costs and probation windows filter out casual entrants, and once a category settles on a few reliable sellers, buyer traffic tends to concentrate. Same pattern on the services category (custom design, escrow-related side work, translation, verification services). Started with a long tail, converged to a short list. ## What has fragmented Documents. At launch this was one category. Today it is a set of subcategories reflecting the actual types of documents vendors offer. The fragmentation happened because buyers searching for one document type were getting flooded with irrelevant listings, and the operator responded to reader feedback by splitting the taxonomy. Same on hardware. Started as one bucket, now split by tool class. ## What has vanished Two categories that existed at launch no longer have active listings. Neither vanished because of an operator decision. They vanished because vendors stopped listing and no new vendors filled the slot. Buyer demand did not drop, but the risk-return profile for vendors in those categories shifted in a way that made other storefronts more attractive. The Bureau does not name the vanished categories here because doing so would double as a request for someone to try relaunching them, and the Bureau does not do product suggestions. If you are looking for a vendor in a category that used to exist, check the current top-level list, and if it is not there, it is not there. ## What has emerged One category exists now that did not exist at launch: a set of listings covering fresh-account services (email, hosting, disposable phone number services, prepaid card top-ups). This grew from adjacent activity in the digital goods category and got promoted to its own top-level bucket when the sub-listing count justified it. ## What this pattern means for buyers Vendor categories on any serious Tor storefront are living structures. They drift with buyer demand, operator taxonomy decisions, and vendor economics. A buyer who has not visited in six months should re-check the category tree before assuming their old bookmark still points at what they expected. A buyer looking for a specific product should always start from the current top-level list and drill down, rather than typing in a category name from memory. Category names change even when the underlying product types have not. ## What this pattern means for vendors Consolidation in a category is not a bad sign, it is a stability signal. Fragmentation in a category is a growth signal. Vanishing in a category is a demand collapse. Emergence is a demand-fit event. The operator is watching all of these. When the taxonomy needs revision, it gets revised, usually announced in a signed rotation post alongside a mirror rotation. Readers who watch the rotation posts closely can see the taxonomy changes before they show up on the storefront. ## Editorial method note on this case This case study is based on direct observation of the storefront category tree across the two-year window, plus reader mail volumes broken down by category. No vendors were surveyed. No specific listings are cited. Category-level patterns are what the Bureau is willing to publish. Listing-level patterns are not. --- ## The rotation that never happened, on operator key stability *Nexus has not rotated its signing key in two years. This case study explains why that is the useful data point.* The most interesting rotation in the Nexus story is the one that has not happened. The operator PGP signing key attached to the launch announcement in January 2024 is still the key signing every rotation post today. In two years and change of continuous operation, the signing key has not been rotated once. This is the useful data point. Here is why. ## Why key stability matters The whole PGP verification model rests on a single trust anchor: the operator public key you imported the first time. Every future verification is a check against that same fingerprint. If the key changes, you have to re-import, re-verify, and re-anchor. Every key rotation is a small trust-collapse-and-rebuild for every reader. An operator who rotates the signing key often is signalling either compromise (had to rotate because the private key leaked) or immaturity (rotating for the sake of it, which is a bad habit on a system where trust flows from stability). An operator who has never rotated the signing key across two years is signalling that the private key remains under the operator's exclusive control, and that the operational security around it is at least good enough that a rotation has never been needed. ## What the Bureau checked Every signed rotation post the operator has published since launch was verified by editors against the same operator public key. Every verification returned Good signature. No editor has ever needed to warn readers about a bad-signature post from the Nexus operator. That is roughly ninety signed posts over two years, all under the same key. ## How this compares to other markets Other Tor markets in the same era have rotated their signing keys once or more, in some cases without a clear signed handoff from the outgoing key. When that happens, readers have no way to distinguish a legitimate key rotation from a compromise. Some markets have rotated silently, which is worse. Some have rotated with a proper cross-signed announcement, which is the correct pattern but still forces every reader to redo the trust anchor. Nexus has done none of that. The key has held. ## What would a rotation look like, if it ever happened The operator would publish a signed announcement under the outgoing key. Attached to the announcement would be the new public key, plus a signature over the new key made with the outgoing key. Readers would verify the announcement against the outgoing key (the one on their keyring), extract the new public key, verify its cross-signature, import the new key, and update their anchor. The whole workflow takes a few minutes if the reader has run PGP verification before. Anything shorter than that pattern (a new key that just shows up in a post without a cross-signature, a chat message claiming the key has rotated, a fresh mirror suddenly publishing a different /pgp key) is a phishing attempt. ## The scenario where key stability breaks If the operator's private key is ever compromised (through server seizure, insider theft, or a supply-chain attack on the operator's own equipment) an attacker can sign anything under that key, including a fake mirror rotation, and it will verify. The compromise is not visible to readers because the signatures still validate. This is the one attack vector the pure PGP model does not defend against. Defence in depth here means the operator uses hardware-backed keys, keeps the signing key on an air-gapped machine, and rotates preventively before compromise. Whether Nexus does any of this is not publicly known, and inference from the two-year stability is that either it works or the operator has been lucky. ## Reader takeaway Trust the current signing key because it has held for two years and every rotation posted under it has verified. Do not trust it more than that. If a rotation post ever fails to verify, the Bureau will publish an advisory under the security section within hours. Read that section occasionally. --- ## Dispute arbitration in practice, patterns from reader mail *What actually happens in a dispute, based on the reader mail the Bureau receives about them.* The Bureau receives a steady flow of reader mail about disputes on Nexus Market. Most letters are one of a handful of patterns. This case study summarises the patterns, what actually happens after a dispute is opened, and what buyers can do to shift the outcome in their favour before a dispute is even opened. ## Pattern one, the vendor ghosts Buyer places order, deposit clears, vendor never ships and stops responding to messages. Buyer opens a dispute at the seven-day mark. Moderator checks the vendor's recent activity, sees the vendor has gone dark on multiple orders, cosigns with the buyer to refund the deposit. Vendor's bond gets partially forfeited if the pattern is widespread enough. Outcome for the buyer: full refund minus network fees, usually within seventy-two hours of opening the dispute. This is the most common dispute type in reader mail. Buyers who opened disputes on ghosting vendors report the moderator response as quick and consistent. ## Pattern two, the shipment is late but arrives Buyer places order, deposit clears, vendor ships slower than the vendor's own advertised window. Buyer messages the vendor, no response for several days. Buyer opens a dispute at the ten-day mark. Vendor responds to the dispute (they had noticed the message system but had not answered), explains a shipping delay, provides some form of tracking or confirmation. Moderator waits. Package arrives. Moderator closes the dispute in the vendor's favour. Buyer finalises normally. Outcome: no refund, no penalty. Reader mail on this pattern is often frustrated because the buyer felt the vendor should be penalised for the message delay. Moderators generally do not penalise for slow messages alone, they penalise for undelivered orders. ## Pattern three, the product does not match the listing Buyer receives the order, item is not what was advertised. Buyer opens a dispute with photographic evidence of the mismatch. Moderator checks the listing, checks the photos, judges. Common outcomes: full refund if the mismatch is clear (wrong item entirely), partial refund if the mismatch is a matter of degree (weight short, potency lower than claimed). Vendor's reputation takes a hit either way. Reader mail on this pattern varies more in outcome. Buyers who provide clear photos and a clean message trail report favourable outcomes more often than buyers whose evidence is weak or whose message history includes accusations before facts. ## Pattern four, the seller-favours-vendor complaint Buyer opens a dispute, moderator cosigns with the vendor, buyer feels the ruling was wrong. Reader writes to the Bureau asking whether moderators are systematically biased. The Bureau's read from the mail volume: no systematic bias visible. Moderators generally cosign with whichever side has the stronger evidence trail. Buyers who report unfavourable rulings almost always turn out, on inspection of their own account of the case, to have a weak evidence trail (no photos, accusatory messages before evidence, unrealistic complaint scope). Buyers with strong evidence trails rarely report unfavourable rulings. This does not mean moderators are always right. It means the buyers who feel wronged are often not wrong to feel wronged individually, but the pattern across all dispute mail does not show a systemic problem. ## What buyers can do before a dispute Encrypt shipping details to the vendor PGP key at order time. Keep every message about the order polite and factual. Take photos of the package on arrival, unopened, with a piece of paper showing the current date visible in the frame. Open a dispute only when the vendor has failed to respond for at least seventy-two hours after a clear question. ## What buyers can do during a dispute Provide evidence up front. Do not accuse. State facts, dates, message references. Attach photos. Answer moderator questions promptly. Do not open multiple parallel disputes on the same order. Do not threaten the vendor. All of these hurt your case if they end up in the message trail the moderator reads. ## The role of the multisig contract in disputes The whole reason disputes work on Nexus is that the coin is in the 2 of 3 multisig contract, and the moderator's signature is the second one needed to move it. If the market held custody, the moderator's cosign would just be an internal database change and the operator could reverse it at any point. Because the moderator has to actually sign a multisig transaction, the settlement is durable and cannot be silently undone. --- ## The February 2026 phishing wave, three domains burned in six days *A case study on a specific phishing wave that hit Nexus, how it was spotted, how it was neutralised.* In late February 2026, three lookalike clearnet domains were registered targeting Nexus Market. Each hosted a copy of the login page. Within six days all three had been burned by community reports and cross-verification against the signed rotation. This case study walks through what happened. ## Domain profile All three were on the same TLD family. Registration timestamps were within 48 hours of each other, suggesting a single operator or coordinated ring. Two used cheap hosting on well-known free tiers. One paid for slightly better hosting. All three used Cloudflare in front of the origin, standard operational pattern for short-lived phishing infrastructure. None of the three domains were on .onion. That fact alone would have caught the majority of readers, because Nexus is a Tor storefront and every real address ends in .onion. But the domains showed up in some search results, and readers who clicked without thinking landed on the clone. ## Login pages Pixel-perfect copies of the Nexus login form, complete with the DDoS wait counter animation. Two of the three even had a scraped copy of the current Nexus captcha image embedded (stale, but present). The third had no captcha, just went straight to a credential form. None of the three could produce a signed rotation announcement. This was the fatal gap. ## Community detection A reader forwarded one of the URLs to the pinned Dread thread with a screenshot. Another reader recognised the pattern and pointed out that the address was clearnet, not onion. The thread propagated. Within 36 hours, community verification against the current signed rotation had identified all three domains as clones. ## Bureau response Editors verified the reports against the operator PGP key. All three claimed addresses failed verification. The Bureau published a short advisory in the security section within four hours of the third confirmation, listing the three domains and the reader defence steps. ## Timeline resolution Cloudflare received abuse reports on all three domains, from multiple reporters. Two were nullrouted within 48 hours of the first report. The third took slightly longer because the abuse mechanism was slower for that particular hosting stack. All three were unreachable within six days of first detection. ## Lessons for readers The captcha URL check would have caught all three on the first session (URL bar showed a clearnet domain, captcha embedded either nothing or a stale onion). The PGP verification against signed rotation would have caught all three at the address-listing stage. Both defences worked as designed. Neither is optional. ## Lessons for the Bureau The domain squat pattern seems to be increasing in frequency, so the Bureau updated the phishing defence report to emphasise the never-clearnet-search rule more prominently. --- ## Summer 2026 DDoS wave, three days of queue pressure *A case study on a specific coordinated pressure event and how Nexus absorbed it.* Across a weekend in early July 2026, Nexus Market experienced coordinated network pressure lasting roughly 72 hours. The queue held. No rotation was required. This case study documents what happened and what the reader saw. ## Onset Late Friday afternoon UTC. Queue times on the primary mirror extended from the typical 30-60 seconds to about 2-3 minutes. Backups initially held at normal times, suggesting attackers had concentrated on the primary address. ## Peak Saturday evening UTC. Primary queue reached about 4 minutes at peak. Backup 1 reached about 2 minutes. Backup 2 held around 90 seconds throughout. ## Reader impact Readers on the primary during peak reported successful sessions after waiting the 4-minute queue. Readers who switched to backups typically completed sessions faster. No reader reported a fully failed session across the window that lasted longer than one retry. ## Bureau inbox during the event About 40 reader letters over the 72-hour window. Roughly half asking whether the market was down. Roughly a quarter reporting queue times and asking whether the operator was aware. A quarter reporting they had bought a listing and wanted to know if the order would still process (yes, it did). ## Operator response Around 24 hours into the event, the operator posted a signed note on the pinned Dread thread acknowledging the wave and noting the queue was working as intended. No rotation was announced. No infrastructure change was made. The event ended on its own within about 12 hours of the note. ## Post-event observations No mirror addresses were rotated in the following two weeks, so the operator did not judge the event as compromising any specific address. The captcha continued to render correctly throughout. No security advisory was published because the event did not compromise any reader account, credential, or transaction. ## Bureau read on the event The queue mechanism worked as designed. Multiple mirror addresses gave readers viable alternatives when the primary slowed. The operator's public acknowledgment reduced reader confusion. The whole event is an example of a coordinated pressure attempt being absorbed without any structural damage. --- ## Monero adoption across Nexus buyer accounts, 2024 to 2026 *How buyer preference shifted from Bitcoin to Monero as the default deposit coin.* At launch, Nexus Market accepted Bitcoin and Monero. New buyer accounts had to pick a default coin at first deposit. Roughly 70 percent picked Bitcoin. Two years later, new accounts default to Monero out of the box, and roughly 85 percent of new deposits are Monero. This case study walks through the shift. ## Launch state, 2024 Reader mail suggested most new buyers picked Bitcoin because it was what they already had. Monero required a separate wallet setup, non-KYC funding path, and enough education to understand why chain privacy mattered. Bitcoin required none of that. The operator's wallet panel at launch treated the two coins equally. No default. Reader had to choose. Default choice tended toward familiarity. ## Reader mail patterns, mid-2024 Bureau inbox shifted noticeably in the second half of 2024. Reader mail began asking specifically about Monero: how to source it without KYC, which wallet to use, how to swap Bitcoin to Monero without an exchange. This suggested a demand for Monero education even from readers who had defaulted to Bitcoin. The Bureau responded by publishing the coin economics report in October 2024, laying out the trade-offs. This became the most-linked-to Bureau piece for the next year. ## Operator UI change, mid-2025 The wallet panel was reworked to default new accounts to Monero. Bitcoin remained available but required an explicit switch. Litecoin was added as a third option in the same UI revision. This was announced in a short signed operator note. The Bureau covered it as a Monero-adoption signal from the operator side. ## Reader mail patterns, 2025 to 2026 Volume of coin-questions dropped by about half after the UI change. New buyers who defaulted to Monero without thinking about it simply proceeded, and the questions the Bureau received shifted from what-coin-to-use to how-to-source-Monero. This latter question is well-covered in the coin economics report. RoboSats, Cake Wallet swap, Bisq. Reader mail on the topic became largely referrals to the report rather than fresh questions. ## Present state, 2026 Roughly 85 percent of new deposits Monero, per the operator's own periodic transparency notes (which the Bureau cannot verify independently but which match reader mail patterns). Bitcoin usage now concentrated in vendors who explicitly price in BTC for category reasons and buyers who hold BTC from before the shift. ## What this case demonstrates UI defaults matter more than education in shifting user behaviour. Reader education worked slowly. Changing the default worked immediately. This is not a Nexus-specific lesson, it applies to any UX with a coin-choice prompt. ## Editorial method note Deposit ratios cited in this case study are from operator transparency notes. The Bureau cannot independently verify per-coin deposit ratios. Reader mail patterns and operator UI changes are directly observable and are the primary evidence for the shift narrative. --- ## Category taxonomy drift, a two-year retrospective *How the operator has reshaped the vendor category tree in response to buyer demand, in specific detail.* The Nexus Market category taxonomy at launch had eight top-level buckets. Two years later it has eight top-level buckets, but the internal composition has shifted significantly. This case study walks through the specific changes. ## What consolidated Two categories that had many active vendors at launch have consolidated toward a shorter list of survivors. The consolidation happened because bond costs filter out low-quality newcomers over time, and buyers cluster around vendors with clean dispute histories, leading to compounding advantage for established sellers. The Bureau observation: consolidation is not a bad sign, it is a stability signal. Consolidated categories have lower dispute rates and higher finalisation ratios than fragmented ones. ## What fragmented One category that was a single bucket at launch is now split into subcategories after buyer complaints that search returned too many irrelevant listings. The operator responded with a taxonomy revision that gave the subcategories their own filters. Fragmentation is a growth signal: the underlying category was popular enough that the coarse-grained bucket became unusable. ## What vanished Two subcategories present at launch no longer have active listings. Neither vanished because of an operator decision. They vanished because vendors stopped listing and no new vendors filled the slot. This can happen for several reasons: better opportunities on competing storefronts, category-specific regulatory changes in vendors' jurisdictions, or the underlying product simply going out of fashion. The Bureau does not name the vanished subcategories. Doing so reads as a request for someone to relaunch them, which is not the Bureau's role. ## What emerged One entirely new subcategory appeared in late 2025 covering fresh-account services (email, hosting, disposable phones, prepaid card top-ups). Started as adjacent listings in the digital-goods category. Grew to enough active listings that the operator gave it its own subcategory filter in early 2026. Emergence is a demand-fit event. A subcategory only appears when there is enough vendor supply and buyer demand to justify the taxonomy work. ## Operator response cadence Taxonomy revisions happen twice a year on average. Announced in signed rotation posts alongside mirror updates. Readers who watch rotation posts see taxonomy changes before they show up on the storefront. ## Reader implication A buyer who has not visited Nexus in six months should not assume the category tree is unchanged. Start from the current top-level list and drill down. Do not type in a category name from memory. Category names change even when the underlying product types have not. ## What this case does not cover Specific vendor names. Specific listing counts. Category-level pricing trends. All of these are beyond the Bureau's scope and would put us in vendor-review territory, which is explicitly outside our editorial policy. --- # Section: Dossiers ## The Nexus operator PGP key, technical dossier *Where the key lives, what it does, why it matters, how the reader anchors trust to it.* The Nexus operator PGP key is the single trust anchor of the entire storefront ecosystem. Every mirror rotation, every signed announcement, every operator statement rides on this key. If the key is genuine and remains under the operator's control, everything signed by it is real. If the key is not genuine or is compromised, everything falls. ## Where the key is published Two primary sources. The pinned Dread profile of the operator carries the public key in the profile description or in a pinned post. Every current Nexus mirror serves the same public key from the /pgp path (accessed after login). Both sources are considered authoritative. Neither alone is sufficient, the reader should fetch from both and cross-check the fingerprint. ## What the key is used for Every signed rotation announcement. Every operator statement about feature changes. Every advisory about phishing patterns. Every retrospective. If a message from the operator does not carry a valid signature from this key, it is not from the operator. ## The fingerprint anchor The fingerprint is 40 hexadecimal characters split into 10 groups of 4. The reader's job is to record the fingerprint once, from two independent sources, and refer back to it on every future verification. The Bureau does not publish the specific fingerprint on this page. This is deliberate: if we published it, and this page were ever compromised, an attacker could poison the fingerprint alongside a fake key. Readers are expected to fetch the fingerprint from Dread and from a mirror's /pgp path themselves. ## Cross-check method Fetch the key from Dread. Fetch the key from a mirror /pgp path. Run gpg --import on both fetched files into a fresh keyring. Compare the fingerprints with gpg --list-keys --with-fingerprint. If they match, the key is genuine (with high confidence). If they do not match, at least one source is compromised, and the reader should assume the worst and not import either key until the situation clarifies. ## Key stability history See the case study on the key that has not rotated. Two years of stability. Every signed rotation post verifies against the same fingerprint. No editor has ever needed to publish a bad-signature warning about a message signed under this key. ## What happens if the key is ever compromised An attacker with the private key can sign anything, including fake rotations, and it will verify against every reader's keyring. The reader has no way to detect this without out-of-band information. Defence in depth here means the operator keeps the private key on hardware or air-gapped storage, and defence for the reader means watching for out-of-character behaviour (a rotation that lands on an address that behaves oddly, a captcha string that does not match the URL bar, a login page that looks slightly different). If in doubt, do not log in. ## Key rotation, if it ever happens A key rotation would be announced under the outgoing key, with the new public key attached and cross-signed. The reader verifies the announcement under the outgoing key, checks the new key fingerprint against multiple sources, imports the new key, and updates their trust anchor. Any key rotation that skips the cross-signature step is not from the operator. ## What to store on your side The imported operator public key. The fingerprint (written down on paper, in a password manager, or in an encrypted local note). The date you first imported the key. Ideally, a screenshot of the two Dread posts and /pgp paths you cross-checked against, in case you ever need to prove to yourself later that the fingerprint has not changed on you. --- ## The 2 of 3 multisig flow, step by step *Every step in the multisig escrow flow, from key generation at order time to release at finalisation.* This dossier walks through the 2 of 3 multisig flow on Nexus Market end to end, from the moment the buyer clicks to place an order to the moment the coin releases from escrow. ## Key generation, order time When the buyer places an order, the storefront generates three private keys for that specific order. One private key is held by the buyer through their storefront account. One is held by the vendor through theirs. One is held by the platform. The three public keys are combined into a multisig address, and the buyer sees this address on the checkout page as the deposit destination. The keys are per-order, not per-account. This matters: even if a vendor's account is compromised in some future scenario, only the keys for currently open orders are exposed, not the vendor's historical order coin (which has already released). ## Deposit Buyer copies the multisig address, deposits the exact amount from their own wallet, waits for confirmations. Monero requires two confirmations minimum, Bitcoin ten, Litecoin around six. When the confirmations complete, the storefront marks the order as escrowed. ## Vendor ships Vendor sees the deposit confirmed on their orders page, ships the item, updates the storefront with any tracking or shipping metadata they choose to share. Message system available for coordination. ## Buyer marks received Package arrives, buyer checks the item against the listing, marks the order received in the storefront. This is the buyer's signature on the release. One of the three needed. ## Vendor signs release Vendor sees the marked-received flag, signs the release. This is the second of the three needed. The multisig transaction now has two signatures, which is enough. The transaction broadcasts to the coin's network. Coin moves from the multisig address to the vendor's wallet. Platform key never moves in this path. This is the happy path, the vast majority of orders, and it settles without any moderator involvement. ## Dispute path, buyer opens Buyer opens a dispute instead of marking received. Storefront notifies the vendor. Vendor responds through the message system with their side. Moderator reads the entire message thread, checks vendor dispute history, checks any photographic evidence, judges. Moderator cosigns with whichever side they judged correct. If moderator cosigns with buyer: multisig transaction constructed with buyer + platform signatures, sending coin to a refund address the buyer specifies. Vendor's signature not needed. If moderator cosigns with vendor: multisig transaction constructed with vendor + platform signatures, sending coin to vendor's wallet. Buyer's signature not needed. ## Dispute path, vendor opens Symmetric case, rare. Vendor opens a dispute because the buyer has failed to mark received despite the vendor's evidence of delivery. Moderator reads both sides, cosigns with whichever they judge correct. Same signature-combination logic. ## Timeout path, buyer inaction Buyer neither marks received nor opens a dispute for an extended period after delivery has occurred. Some storefronts have automatic finalisation at this timeout. Nexus does not, as of the last observation. Coin sits in the multisig contract indefinitely until either the buyer signs, the vendor opens a dispute, or the buyer opens a dispute. Neither side loses the coin, but the vendor has to wait. ## Key management on the storefront side The storefront generates keys server-side. Buyer and vendor keys are held on the storefront database, encrypted with the account password. Platform key is held on the storefront infrastructure separately. When the account holder signs a release, the storefront uses the account password (submitted during the sign action) to decrypt the key and produce the signature. This means an attacker with the account password can sign releases, which is why account passwords should be strong and not reused. The mnemonic seed issued at registration is the recovery path if the password is lost, and it should be treated as equivalent to the password for security purposes. ## What could go wrong Storefront compromise. If the entire storefront infrastructure is compromised, an attacker could construct signatures using the platform key and either buyer or vendor keys held in the database. This is why the platform key alone is not sufficient: even a full server seizure only gets the attacker one of three keys per contract, plus whatever account passwords they can crack. It does not give them the ability to unilaterally move any single order's escrow. Multisig library bug. If the library the storefront uses to construct multisig transactions has a bug that lets an attacker forge a signature without knowing the private key, all deposits are at risk. This has never happened on a serious multisig library, but it is not zero probability. --- ## The captcha system, address embedding and phishing defence *How the Nexus captcha works, why the address is baked into the image, what phishing clones cannot copy.* The Nexus Market login captcha is more than a bot-blocker. It doubles as a phishing check by embedding the current onion address inside the captcha image itself. This dossier explains the mechanism and why it works. ## The mechanism When a reader lands on the login page of any Nexus mirror, the storefront generates a fresh captcha image. Two things go into the image: the puzzle (a distorted string the reader has to type) and the current mirror address printed in small text along the bottom edge. Both are rendered server-side into the same image file, which the reader's browser downloads and displays. ## Why the address in the image Because it costs a phishing clone something to fake. A clone that scrapes the Nexus login page gets an image with the real Nexus address baked in. If the clone displays that image unchanged, the reader can see that the address in the image does not match the address in the URL bar, and the clone is caught. The clone could regenerate the image with the clone's own address baked in, but that requires infrastructure the clone operator would rather not build. Most clones do not bother, which is why the captcha check works reliably against the median phishing attempt. ## Reader instruction Every session, before typing the password, glance at the small text at the bottom of the captcha image. Compare against the URL bar. If they match, proceed. If they do not, close the tab. The check takes five seconds and catches the vast majority of phishing clones on the first attempt. ## Refresh cadence The captcha image regenerates on a rotating cycle, currently every twenty seconds under peak load and every forty-five seconds under typical load. Each regeneration produces a new puzzle and a new copy of the current address. A phishing clone that scrapes and caches a single image gets a copy that ages out within a minute, forcing the clone to either scrape continuously (which is fingerprintable server-side) or fall behind. ## What the check does not catch A sophisticated clone that regenerates captchas server-side with the clone address baked in. This requires the clone operator to implement captcha generation themselves, which is more work than most clones do, but not impossible. The Bureau has seen approximately three clones in the past year that made this effort. Against a clone that generates its own captchas, the reader's remaining defence is PGP verification: the clone address will not appear in any signed rotation from the operator. The PGP check is the strong anchor, the captcha check is the fast per-session check that catches most clones without invoking gpg every time. ## Interaction with anti-DDoS queue The anti-DDoS queue holds the reader for twenty to sixty seconds before the captcha renders. This means a clone that wants to display a captcha image immediately (skipping the queue) is fingerprintable as a clone just by that fact. Serious readers who use Nexus regularly know that the wait is a genuine sign, and instant login pages are suspicious. ## History of the mechanism The captcha-with-embedded-address pattern was not present at Nexus launch. It was introduced in mid-2025 after the operator observed phishing patterns that exploited the reader's inability to check the address in real time. The pattern is now standard across serious Tor storefronts. Other storefronts picked up the same design within six months of Nexus rolling it out. --- ## The onion address, structural dossier *What a v3 onion address actually is, how it is constructed, why the prefix does not matter cryptographically.* Every current Nexus Market mirror address is a v3 Tor onion address. This dossier explains what such an address actually is, how it is derived, and why some parts of it matter cryptographically while others (like the prefix) do not. ## Structure A v3 onion address is a 56-character string ending in .onion, made up of a subset of the base32 alphabet (lowercase a to z and digits 2 to 7). The whole address encodes three things: the hidden service's public key (32 bytes), a checksum (2 bytes), and a version byte (1 byte). Together these encode into the 56 characters you see. ## The public key The 32-byte Ed25519 public key of the hidden service. This is the cryptographic identity of the service. Anyone who reaches this address is proving to the network that they want to talk to whoever holds the corresponding private key, and only the holder of that private key can respond as the service. ## The checksum A 2-byte truncation of a SHA-3 hash over the public key concatenated with the version byte. Its purpose is typo detection: if a reader mistypes an address, the checksum will not match, and Tor Browser refuses to route the request. This catches most typos before they become clicks. ## The version byte Currently version 3. Version 2 addresses (older, 16-character format) have been deprecated for years and are no longer supported. Anything that looks like a v2 address in 2026 is either a museum piece or a scam. ## The prefix The first few characters of the address (like nexus...) are what most readers use as a visual sanity check. Cryptographically they carry no weight: they are just the first few base32 characters of the public key encoding. But because generating an address with a specific prefix requires brute-forcing until a matching Ed25519 keypair happens to produce that prefix, longer prefixes are more expensive. A four-character prefix like nexu takes seconds on a laptop. A six-character prefix like nexusa takes hours. A twelve-character prefix would take years of GPU time. This is why phishing clones can match the first few characters but not the whole address. ## Why full address comparison matters A phishing address that matches the first eight characters of a real Nexus address looks like the real address at a glance. The reader who eyeballs only the beginning of the string will not spot the difference. Every character of the 56-character body has to match for the address to be the real one. The reader defence here is copy-paste, not typing. Copy from a source you trust. Paste. Never type. ## Why v3 replaced v2 v2 addresses were 16 characters and derived from an 80-bit truncated hash of a 1024-bit RSA public key. This was strong enough for years but became increasingly weak as computing power grew. v3 addresses are derived from a 256-bit Ed25519 key, which is significantly stronger and resistant to attacks that were becoming feasible against v2. The switch happened in 2020-2021. Every serious hidden service migrated. Any surviving v2 addresses in 2026 are either shells or scams. ## How Nexus mirrors relate Each Nexus mirror address is a distinct v3 onion address, meaning each mirror has its own Ed25519 key. The addresses do not share cryptographic identity, they share a backend. When a reader reaches any mirror, they end up at the same storefront because the storefront is configured to answer on all three onion addresses, not because the addresses are cryptographically related. This has an implication for the operator: rotating a mirror means generating a new Ed25519 keypair and adding it to the storefront's configured onion set. It does not mean touching the operator's PGP signing key, which is a separate thing entirely. --- ## Tor network architecture, what a hidden service actually is *The three-relay routing model and why Nexus is only reachable through Tor Browser.* Nexus Market is a hidden service on the Tor network. It cannot be reached through a normal browser because a normal browser cannot resolve .onion addresses. This dossier explains what Tor is doing under the hood and why hidden services work the way they do. ## The three-relay circuit When Tor Browser connects to any destination, it builds a circuit through three relays. Each relay knows only its adjacent hops, never the full path from you to the destination. The first relay is your guard. Tor uses the same guard for months to reduce the risk of anonymity attacks. The guard knows you are using Tor but does not know what you are doing. The second relay is a middle. It sees encrypted traffic passing through and knows neither the source nor the destination. The third relay is an exit. It sees your traffic in the clear (unless the destination itself uses HTTPS or is a hidden service, in which case the exit sees encrypted traffic even to the destination). For a hidden service like Nexus, there is no exit in the traditional sense. Both the client and the service build their own circuits and meet at a rendezvous point inside the Tor network. ## Hidden service descriptors Every hidden service publishes descriptors to the Tor network directory. The descriptors tell clients which introduction points to use to reach the service. When you type an onion address, Tor Browser looks up the descriptors, contacts an introduction point, and negotiates a rendezvous. Descriptors are re-uploaded periodically. If a hidden service's descriptors go stale, clients temporarily cannot reach the service until fresh descriptors propagate. This is one reason why a mirror can appear temporarily down and then return without any actual change to the storefront. ## Why onion addresses are Tor-only The public key encoded in an onion address is meaningful only inside the Tor network. There is no clearnet DNS record for it. There is no clearnet HTTP path that returns anything at that address. The address is a Tor-network-internal identifier, and only Tor Browser (or another Tor-aware client) can resolve it. This is why anyone claiming Nexus has a clearnet address is either lying or confused. The storefront is definitionally Tor-only. ## Guard node stability Your Tor Browser picks a guard on first use and keeps it for approximately three months. This is deliberate: shuffling guards frequently increases the probability that you will eventually pick a hostile guard, which reduces your anonymity. Long-lived guards reduce this risk. The practical implication for readers: if a particular Nexus mirror always seems slow for you, it may be your guard's fault. New Identity in Tor Browser will pick fresh circuits but not a fresh guard. To fully replace the guard, you would need to reset Tor Browser state. --- ## GnuPG basics for Nexus readers *The minimum GnuPG knowledge a reader needs to verify Nexus rotations.* Verifying Nexus Market rotations requires GnuPG. This dossier covers the minimum GnuPG knowledge a reader needs to run the verification workflow reliably. ## Installation Linux. Almost every distribution ships GnuPG. Run gpg --version. If nothing responds, install via your package manager. macOS. Install via Homebrew: brew install gnupg. GPG Suite is an alternative that includes a GUI. Windows. Install Gpg4win from gpg4win.org. This includes Kleopatra, the GUI covered in the PGP verification report. ## The commands you need # Import a public key gpg --import key.asc # List keys on your keyring gpg --list-keys gpg --list-keys --with-fingerprint # Verify a signed message gpg --verify signed-message.txt # Delete a key gpg --delete-key KEY_ID That is the minimum. You never need to sign anything, encrypt anything, or manage a keyring beyond these commands to verify Nexus rotations. ## Keyring hygiene The Bureau recommends a fresh keyring dedicated to Nexus verification, kept separate from any personal PGP keyring you may have. Use gpg --homedir ~/.gnupg-nexus in every command to isolate. This prevents your Nexus verification from being affected by any other key drift on your personal keyring, and vice versa. ## Fingerprint verification After importing the operator key, run gpg --list-keys --with-fingerprint and compare the printed fingerprint to what you fetched from the operator Dread profile and from a mirror /pgp path. Store the fingerprint (paper, encrypted note, password manager) so you can verify future keyring state against it. ## Common mistakes Copying only part of a signed message. The signature covers every byte from the opening -----BEGIN PGP SIGNED MESSAGE----- to the closing -----END PGP SIGNATURE-----. Missing bytes fail verification. Adding trailing whitespace or newlines. Some editors add invisible whitespace. Use a plain text editor and save the file as UTF-8 without BOM. Importing the wrong key. If you accept an operator key from an unverified source and then verify a rotation with it, everything will look fine even if both are fake. Cross-check the key fingerprint against at least two independent sources. Treating the trust warning as an error. WARNING: This key is not certified with a trusted signature is expected. Ignore it. Read the actual verification result on the line above. ## What GnuPG does not do for you It does not check whether the address inside a signed message is a good address to visit. It checks that the message came from the key holder and has not been altered. Everything downstream (is this address the right one, is this vendor a good vendor) is your responsibility. --- ## Wallet software comparison, what actually to install *Wallet software recommendations for each coin, with the reasoning behind each.* The Bureau's wallet recommendations across all three coins Nexus accepts. Each comes with the reasoning behind why it made the shortlist and what its trade-offs are. ## Monero Feather Wallet is the current default recommendation for desktop. Lightweight (no full node required), open source, actively maintained by developers with a good track record. Comes with a portable Windows build and Linux AppImage that runs without installation. Good for readers who want minimum setup. Cake Wallet is the mobile default. Available on iOS and Android. Includes a built-in swap that lets you swap Bitcoin to Monero inside the wallet without touching an exchange. Good for readers who use their phone more than their laptop. Monero GUI is the reference wallet, developed by the Monero core team. Requires either a full node (large disk, days of sync) or a remote node (fine but not maximally private). Best privacy story. Best for readers who want to run their own node. ## Bitcoin Sparrow is the current best privacy-aware Bitcoin wallet. Coin control support, PSBT support, hardware wallet integration, connects to your own Bitcoin node if you have one. Some learning curve but the interface is well-documented. Electrum is the lightweight fallback. Reliable, mature, widely used, less focus on privacy features than Sparrow. Fine for basic wallet needs. Do not use browser-based Bitcoin wallets, custodial exchange wallets, or mobile-only Bitcoin apps for market deposits. All three are common sources of buyer fund loss. ## Litecoin Electrum-LTC is the desktop wallet. Same interface family as Electrum for Bitcoin. Fast, reliable, minimal setup. This is the only wallet the Bureau recommends for Litecoin specifically because most other Litecoin wallets are abandoned or maintained inconsistently. ## Hardware wallets For Bitcoin: Trezor or Ledger, both work with Sparrow. For Monero: Trezor supports Monero as of the recent firmware. Ledger has partial Monero support that requires more setup. If you are new to Monero on hardware, use Trezor. Hardware wallets protect the private keys from software compromise on your host operating system. Worth the cost if you hold coin for extended periods. Not worth the friction for coin you plan to spend inside a week. ## What not to use Browser extension wallets like MetaMask. Wrong network anyway, and even for Bitcoin extensions, the security model is not fit for Tor market use. Any wallet that requires an email address at setup. Any wallet integrated with an exchange. Any wallet that does not publish the private key or seed derivation on request. The reader must always be able to leave the wallet with their coin. --- # Section: Notes ## Why three mirrors, not five, not ten *A short note on the size of the mirror set.* The obvious question about the current Nexus mirror set is why it sits at three rather than five or ten. The answer is that three is the point where the marginal value of another mirror falls below the marginal cost. With one mirror, any single routing failure is a total outage for the reader. With two, you have a fallback but no third option if the fallback also has a bad guard. With three, you cover most single-outage scenarios cleanly and almost all double-outage scenarios by chance. Adding a fourth mirror covers only rare triple-outage scenarios, and each additional mirror after that covers vanishingly rare compound scenarios. The cost side is not zero. More mirrors mean more surface for phishing clones to blend into. More entries the reader has to eyeball against the captcha URL match. More work for editors verifying signed rotations. More cognitive load for the reader deciding which mirror to try first. Three is the small number that trades off well. The operator has been at three for a while. Occasionally the set has drifted to four during a rotation transition (new address added before old one retired), which is a normal shape. It has not stayed above three for extended periods, which is a deliberate choice. --- ## Reading a vendor page in two minutes *The specific numbers to read and the specific ones to ignore.* A vendor page on Nexus Market shows several numbers. Not all of them are equally useful. Here is the two-minute read. ## Dispute count divided by total orders Below 5 percent is healthy. 5 to 10 percent is a yellow flag, read recent reviews before ordering. Above 10 percent is uniformly a red flag except for categories where higher dispute baselines are normal (fragile packaging, ambiguous quality metrics), and even for those, above 15 percent is bad. ## Finalisation ratio Orders that closed cleanly divided by all completed orders. Above 95 percent is healthy. Below 90 percent means one in ten orders required moderator intervention, which is worth investigating in the recent reviews. ## The last twenty reviews Not the lifetime average. Scroll to the bottom. Read the review text for the last twenty. If the recent reviews are noticeably worse than the older ones, the vendor is going through something. Standard something: supply source changed, vendor got busier and started dropping details, vendor is dealing with a stealth-quality regression they have not yet fixed. Read the complaint pattern, not the star rating. ## What to ignore Lifetime star average. Individual glowing five-star reviews from unknown accounts. Testimonials in the vendor description. Vendor's own text about how careful their packaging is. None of these tell you anything. The dispute ratio and the last twenty reviews are the whole story. ## When to walk away If any of the above numbers looks off. There are many vendors on any Tor storefront. Time you save by picking a healthy vendor first is time you do not lose on a dispute later. Two minutes on a vendor page saves a week of dispute mail. --- ## The first order protocol, small and cheap *How to run your first order on a new vendor without much at stake.* The first order with any new vendor on Nexus Market should be structured to minimise what you lose if the vendor turns out to be worse than the page suggests. Small quantity. Cheap product. Standard shipping (not expensive express). Standard escrow (not finalise early). Use the on-storefront message system with polite factual language. Encrypt any address you send to the vendor with their PGP key. Wait for the order to arrive cleanly. Check it against the listing. If everything matches, that vendor gets a second order from you, larger this time. If anything is off, open a dispute early with clear evidence and move on. The point of the first order is calibration, not commerce. You are buying information about the vendor, and the product is a happy side-effect. Buyers who skip the calibration step and place a large first order to a vendor they have not tried before are the buyers who write to the Bureau most often after something goes wrong. --- ## Do not finalise early, one more time *A short note on the FE trap, because it never stops catching new buyers.* Finalising early (marking an order received before it actually arrives) drops escrow protection. Once you finalise, the coin is out of the multisig contract and the vendor has it. If the item then does not arrive, there is no dispute path to reverse the release. Vendors sometimes ask for FE because they want the money before the shipping window has closed. Some vendors have reasons that are not scams (short on runway between shipments, moving between storefronts, needs to restock). Most FE requests are scams. A new vendor asking a first-time buyer to FE is uniformly a scam pattern. The Bureau's position: do not FE. If a vendor pushes back on the refusal, choose a different vendor. If a vendor you have used before asks you to FE for a good reason, treat it as a favour you are extending, not a normal step, and only for small orders. Escrow protection is what makes Nexus work as a market rather than as an honour system. Give it up and you are buying off the honour system, which is not what you signed up for. --- ## Encrypt anything sensitive with the vendor PGP key *The message system is encrypted, but layering your own PGP on top matters for the fields that matter.* The Nexus message system is encrypted by the storefront. But every message is decryptable by the storefront itself, which means it is decryptable by anyone who compromises or seizes the storefront database. Layering your own PGP on top for anything sensitive changes this. If you encrypt your shipping address to the vendor PGP key before sending, the storefront sees only ciphertext for the address field. A seized database returns nothing useful to whoever seized it, at least for the encrypted parts. The parts to encrypt: name, address, phone number, tracking number if you exchange one, any identifiers that could link the order back to your real identity. The parts you do not need to encrypt: order coordination questions, dispute discussion, generic messages. Every vendor page has the vendor PGP key published at the bottom. Import it. Encrypt sensitive fields with gpg --encrypt --armor -r vendor-key-id. Paste the ciphertext into the storefront message. Vendor decrypts with their private key. This is one habit that costs you two minutes and closes a permanent risk. Worth it. --- ## Where to store the mnemonic *Paper works. Cloud does not. A few options in between.* Registration on Nexus issues a mnemonic seed for account recovery. Where you keep it matters, because anyone with the mnemonic owns the account. Paper. The default. Write the mnemonic on a piece of paper in your own handwriting. Store in a physical location only you access. Multiple copies in different physical locations is fine if the locations are all under your control. Metal. For cold storage over long periods, engrave or stamp the mnemonic into a metal card. Not paranoid, just future-proof. Fires happen. Encrypted local file. Keep the mnemonic in a file encrypted with a passphrase only you know, stored on encrypted local disk that never syncs to any cloud. GnuPG can encrypt a file with a passphrase in one command. Password manager, encrypted vault only. KeePassXC with the database on encrypted local storage is fine. A cloud-synced password manager (LastPass, 1Password with sync) is not. Do not. Screenshot the mnemonic. Save it in a note that syncs to iCloud, Google Drive, Dropbox. Store it in a browser autofill. Email it to yourself. Take a photo. All of these move the mnemonic somewhere out of your exclusive control. --- ## Bookmark hygiene, one entry only *Your Tor Browser bookmarks list should have one Nexus entry. Not five.* Your Tor Browser bookmarks should have one bookmark for Nexus. Not five. Not one per mirror. Bookmark the mirror reference page on this Bureau site (or wherever else you trust to keep the current signed rotation fresh). One entry. When you open the bookmark, you land on a page that lists the current mirrors, and you copy from there. Do not bookmark individual onion addresses. Onion addresses rotate. A bookmark that points at an address the operator retired six months ago is a phishing risk if anyone happened to snap up the retired address (they usually do). Reference-page bookmarks stay valid across rotations. Address bookmarks go stale. This is the difference between a bookmark that reads for years and one that fails as soon as the operator does their job. --- ## First-vendor checklist, thirty seconds *The six things to check before ordering from a vendor you have never used.* Before ordering from a vendor you have never used, run this checklist. Takes about thirty seconds. - Dispute ratio under 5 percent? - Finalisation ratio over 95 percent? - Last twenty reviews consistent with older ones? - PGP key published on the vendor page? - Average shipping time reasonable for the vendor's stated location? - No FE-only requirement? All six yes: proceed with a small first order. Any no: read the recent reviews before deciding. --- ## Withdraw after each order *Do not keep a running balance on the storefront. Sized-to-order only.* Every deposit on Nexus sits behind 2 of 3 multisig, so buyer coin is not custodially held by the operator. But after an order releases, the buyer balance appears on the wallet panel as regular balance, not as multisig-locked. That balance is custodially held until the buyer withdraws. Do not keep a balance on the storefront across orders. Withdraw after each release. The wallet balance you should keep is either zero (nothing pending) or exactly the amount for the next order plus a small buffer for network fees. The reason is not that Nexus is likely to steal your balance (multisig closes the largest attack vectors, and Nexus has run two years without incident). The reason is that a balance you can only recover from the storefront is a balance you lose if anything happens to the storefront. Withdraw promptly. Store coin in wallets under your own keys. --- ## Keep sessions short *Long-lived Tor Browser sessions accumulate risk. Close and reopen.* Tor Browser sessions accumulate state over time. Cookies (locally), history, cached DOM state. None of this is inherently dangerous, but a long-lived session is a longer window for anything to go wrong (extension update, JavaScript on an unrelated tab misbehaving, cross-origin exposure). The Bureau's recommendation: close Tor Browser after each Nexus session. Open it fresh when you need it again. Use New Identity between different market accounts and between browsing Nexus and browsing anything else. This is a small habit, mostly invisible to your workflow if you already close the browser when you finish. Worth reinforcing. --- ## Never stack a VPN under Tor *The combination adds latency and reduces anonymity for most readers.* Common misconception: routing Tor traffic through a VPN adds an extra privacy layer and makes the reader safer. Reality: for the default reader, it usually makes things worse. Reasons. First, the VPN provider now knows you are using Tor. Some VPN providers log this, some do not, but the fact that you are using Tor is now visible to a specific commercial party. Second, latency doubles because you have added an extra hop. Tor is already slow enough. The VPN hop makes it slower for no security gain against the adversaries most readers actually face. Third, some Tor guard-selection algorithms interact badly with VPNs. In some configurations you end up with a smaller effective anonymity set because your entry pattern is unusual. The Bureau's position: use Tor Browser directly. No VPN. If your threat model actually requires a VPN under Tor (specific research or activism scenarios), you already know why you need it and this note is not for you. --- ## Recognising a real Nexus address *Prefix, length, character set. The three quick checks.* Three quick checks to eyeball whether an address is likely a real Nexus mirror before doing full verification: Prefix. All current Nexus onion addresses start with nexus. This is by operator choice, not by cryptographic requirement, but it is a consistent signal. An address that does not start with those five characters is not a real Nexus mirror. Length. Exactly 56 characters before the .onion suffix. Not 55, not 57. If your paste ended up with something shorter or longer, you copied wrong or the address is malformed. Character set. Lowercase letters a to z and digits 2 to 7. No uppercase. No 0, 1, 8, 9. No punctuation. If your address has anything outside this set, it is not a valid v3 onion. These are eyeball checks, not verification. Any address that passes all three still needs to be checked against the current signed rotation before you type a password on it. But an address that fails any of them is guaranteed wrong. --- # Section: Library ## Glossary *Plain-language definitions of every term the Bureau uses across the site.* Every term used across the Bureau, defined in plain language. Alphabetical. Anti-DDoS queueWait page in front of the login form. Holds visitors for 20 to 60 seconds before rendering the captcha. Rate-limits automated credential-stuffing attempts. BondRefundable deposit posted by a new vendor before their first listing goes live. Returned after a clean thirty-day probation. Filters out casual scam-bait accounts. Captcha matchThe practice of comparing the onion address baked into the login captcha image against the URL bar. Catches most phishing clones on the first check. DisputeFormal disagreement over an order. Buyer or vendor opens it. Moderator reads both sides, checks the vendor history, cosigns with whichever side they judge correct. The moderator signature is the second of the two needed to release the coin. EscrowPayment arrangement where funds sit in a multisig contract until both buyer and vendor agree the trade is done. Nexus escrow runs on 2 of 3 multisig. FinalisationMarking an order complete, which releases coin from escrow to the vendor. Do not finalise before delivery. See the note on finalise-early warnings. Finalise early (FE)Marking an order complete before delivery. Drops escrow protection. Almost always the wrong move. Guard nodeThe first Tor relay in your circuit. Tor uses the same guard for months to reduce anonymity attacks that rely on shuffling entry points. MirrorA distinct onion address that resolves to the same storefront backend. Account, balance, orders and messages appear identically on every mirror. Nexus currently publishes three mirrors. Mnemonic seedHuman-readable phrase issued at registration for account recovery. Write on paper. Never screenshot or cloud-sync. Anyone with the mnemonic owns the account. Multisig (2 of 3)Payment contract with three keys held by buyer, vendor and platform. Any two release the coin. Platform key never moves in a healthy order. See the escrow dossier. Onion address56-character string ending in .onion. The public key of a Tor hidden service, base32 encoded. Only Tor Browser can resolve it. See the onion-address dossier. Operator keyThe Nexus operator PGP public key. Every rotation and every operator statement is signed with the corresponding private key. Has not rotated since launch. See the operator-key dossier. PGP signatureCryptographic signature over a message, made with a private key. Anyone with the matching public key can verify that the message came from the key holder and has not been altered. Signed rotationPGP-signed operator announcement listing the current mirror set. Verifying the signature proves the addresses are real. Vendor bondSee Bond. V3 onionThe current generation of Tor onion addresses. 56 characters, Ed25519 public key based. Replaces the older 16-character v2 format. --- ## Timeline, Nexus Market from launch to present *Every recorded event since the operator PGP key was first signed.* Every recorded event in the Nexus Market operational timeline since launch, oldest first.

Primary mirror rotated for the first time. Old primary went dark within one hour of the announcement. June. Multisig 2 of 3 becomes explicit at checkout. The old classic escrow option is removed from the dropdown. All new orders are multisig by default. September. Captcha reworked to embed the current mirror address inside the image. This is now the standard phishing check on the login flow. December. Second primary rotation. Same operator key signed. Nine months on the previous primary. ## 2026 February. Coordinated phishing wave observed. Three lookalike domains registered. Community reports and cross-verification against the signed rotation invalidated all three within a week. April. Third primary rotation. May. Captcha refresh cadence tightened to 30 seconds under typical load, 20 seconds under peak load. July. Coordinated DDoS wave through a summer weekend. Anti-DDoS queue peaked at four minutes. All mirrors remained reachable. No rotation required. Present. Rotation set holds at three. Operator PGP key has not rotated since launch (approaching three years of stability). See the case study on the key that has not rotated. --- ## Mirror reference *Three verified onion addresses currently in the operator signed rotation.* The three onion addresses currently in the Nexus Market operator signed rotation. All three resolve to the same storefront. Pick whichever opens fastest. 01Copy 02Copy 03Copy ## Verify before login Every entry above was verified by an editor against the last signed operator rotation. Before typing your password on any of these mirrors, read the small text at the bottom of the login captcha and confirm it matches your URL bar. --- ## Frequently asked questions *The questions that come up in reader mail most often, answered short.* ## What are the current Nexus mirrors? The three addresses on the mirror reference page. All three resolve to the same storefront. Pick whichever opens fastest. ## Which coin should I use? Monero for privacy default. Litecoin for small orders. Bitcoin only for existing balances. See the coin economics report for the full trade-off analysis. ## How does the escrow work? Every deposit runs on a 2 of 3 multisig contract. Three keys held by buyer, vendor, platform. Any two release the coin. Platform key never moves in a healthy order. See the escrow report. ## How do I verify a rotation? Import the operator PGP key once, run gpg --verify on the signed rotation message, compare the onion inside to the mirror reference. See the PGP workflow report for full detail. ## Is there a clearnet Nexus Market? No. The storefront exists only as a Tor hidden service. Any clearnet page claiming to be Nexus Market is a phishing operation. ## What happens if the URL bar does not match the captcha string? You are on a phishing clone. Close the tab. Open the mirror reference from your bookmark and copy the address fresh. ## Who runs the Bureau? A small editor group with a bookmark to Nexus and enough patience to verify every rotation. Not affiliated with the Nexus operator. Editors are anonymous by policy. See the about section. ## How often are pages here updated? Reports every quarter. Case studies once, then only for corrections. Dossiers when the mechanism changes. Notes as topics arise. Library revised continuously. ## Can I submit a correction? Yes. Through the message system on any Nexus mirror, addressed to the Editor account. Corrections in prose welcome. ## Do you take sponsorship? No. See the editorial policy. ## Is there an RSS feed? Not currently. The Bureau publishes irregularly enough that a feed would mostly be silence. Bookmark the sections you care about and check back. ## What if a mirror stops working? Try another mirror from the reference. If all three are stalling for more than five minutes, check back in an hour. If they are still not resolving after several hours across different Tor circuits, wait for the next signed rotation, which usually happens within a day or two. ## How do I dispute an order? Open a dispute through the storefront interface, provide clear evidence (photos, message trail), answer moderator questions promptly. Do not accuse. See the dispute arbitration case study for patterns. --- ## Further reading *External sources the Bureau considers reliable on Tor market topics.* External sources the Bureau considers useful reading for topics adjacent to Nexus Market. Not all of these are specific to Nexus, but they cover material a reader who wants deeper context will find useful. ## On Tor Browser and hidden services torproject.org/download for the browser itself. First install requires signature verification on the bundle. The download page walks through the check for every operating system. The Tor Project's own documentation on hidden services (the technical docs, not the marketing material) is the authoritative source on v3 onion addresses, descriptor propagation, guard-node behaviour and anti-DDoS mechanisms. ## On PGP The GnuPG manual is dry but comprehensive. Read the sections on key management and signature verification. Skip the sections on the OpenPGP web of trust unless you are actually implementing key certification, which most readers are not. For Windows users, the Gpg4win documentation covers the Kleopatra interface. ## On multisig escrow The Sparrow Wallet documentation covers Bitcoin multisig in accessible language. The Monero project's own documentation covers Monero multisig. Both are worth reading if you want to understand what the storefront is actually doing on the coin side. ## On operational security The Tails documentation on their persistent-storage model, and the Whonix documentation on their two-VM setup. Neither is required for Nexus specifically but both are useful for readers who want to compartmentalise their Tor sessions from their host operating system. ## On Tor market history Nothing worth linking. Most published histories of Tor markets are either sensationalist journalism or academic studies with methodology problems. If you want the shape of the field, read multiple sources and cross-check dates and claims. ## Deliberately not linked Third-party directory sites listing Tor market addresses. Most are outdated. Some are actively harmful (they list phishing clones alongside real addresses without distinguishing). If a directory site has not verified addresses against operator signatures, it is not a reliable source. Chat channels claiming to be operator support for any Tor market. Nexus support is on the on-storefront message system only. Any chat channel claiming otherwise is an impersonation. --- ## Downloads *The Bureau editor PGP key, plus references.* The Bureau maintains a small downloads section. Everything here is signed or verifiable against a published fingerprint. ## Bureau editor PGP public key Used for reader correspondence about corrections and tips. Not the Nexus operator key. Distinct. The key is published on the About / Contact page. Fingerprint is available in this section on request through the message system on any Nexus mirror. ## What is not downloadable here The Nexus operator PGP key. Deliberately not published here to avoid becoming a single source that could be poisoned. Readers must fetch it from Dread and from a mirror /pgp path themselves and cross-check. Screenshots of the storefront. Deliberately not published to avoid becoming a target for phishing clones trying to match specific visual details. Any archive of vendor pages or listings. Deliberately not published because vendor pages are supposed to be checked live on the storefront, not from cached copies. --- ## Full reader checklist, first order to withdrawal *Everything the Bureau recommends, in the order you would do it.* ## Before touching the storefront - Tor Browser installed from torproject.org with signature verified - Security slider set to Safest - Browser window not resized - No extensions installed - GnuPG installed on your operating system - Operator PGP key fetched from at least two independent sources and cross-checked, then imported into a fresh keyring - Current signed rotation verified against the operator key - Mirror reference page bookmarked in Tor Browser ## First login - Copy mirror from the reference bookmark - Paste into Tor Browser - Wait through the anti-DDoS queue - Read the captcha string against the URL bar - Solve captcha, log in ## Registration - Fresh username, never used elsewhere - Strong password, saved in encrypted local password manager only - Mnemonic seed written on paper, stored in exclusively-yours location - Personal PGP key uploaded to profile ## Wallet - Feather Wallet or Cake Wallet installed for Monero - Monero acquired from non-KYC source (RoboSats, Bisq, Cake swap) - Deposit amount sized to first order plus small fee buffer, not more ## Vendor selection - Dispute ratio under 5 percent - Finalisation ratio over 95 percent - Last twenty reviews consistent - PGP key published on vendor page - Reasonable average shipping time - Not FE-only ## First order - Small quantity, cheap product, standard shipping, standard escrow - Address encrypted to vendor PGP key before sending - Polite factual messages only ## Delivery - Photo of package on arrival - Check item against listing - Mark received when everything matches, or open dispute with clear evidence if not ## After release - Withdraw remaining balance to a wallet under your own keys - Do not leave balance on the storefront - Close Tor Browser --- ## Related sites the Bureau reads *A short list of external sites that are worth reading, and one longer list of sites to avoid.* ## Reader sites Tor Project. torproject.org and its documentation. Authoritative on hidden services, guard nodes, descriptor propagation. The download page is where Tor Browser comes from. Monero Project. getmonero.org for the wallet software and the manual on Monero mechanics. Reliable. Feather Wallet. featherwallet.org for the Monero wallet software the Bureau recommends for desktop. Sparrow Wallet. sparrowwallet.com for the Bitcoin wallet software the Bureau recommends for privacy-aware Bitcoin. ## Sites the Bureau avoids Third-party Tor market directories. Most are outdated. Some list phishing clones alongside real addresses without distinguishing. The Bureau does not link to any such directory as a source of Nexus addresses. Ranking sites. Sites that rank Tor markets by some scoring system. The scoring is usually opaque, the operators of the ranking site usually have undisclosed financial interests, and the rankings shift for reasons that have nothing to do with market quality. Chat channels claiming to be Nexus support. Nexus support is on the on-storefront message system only. Any Telegram, Signal, Matrix, IRC or Discord channel claiming to be Nexus support is an impersonation. YouTube tutorials on Nexus. YouTube is not a good format for content that changes with every operator rotation. Tutorials there age poorly and are often demonetised-then-updated by phishing operators taking over old channels. ## The Bureau's own external presence The Bureau does not maintain accounts on Twitter, Reddit, Telegram, Signal, Discord, or any other platform. If you see an account claiming to be the Bureau on any of those, it is an impersonation. ---
