Darknet Market mortality risks

Survival analysis of lifespans, deaths, and predictive factors of Tor-Bitcoin darknet markets
topics: statistics, predictions, Bitcoin, Silk Road, R
created: 30 Oct 2013; modified: 9 June 2019; status: in progress; confidence: possible; importance: 7

I compile a dataset of 87 public English-language darknet markets (DNMs) 2011-2016 in the vein of the famous , recording their openings/closing and relevant characteristics. A survival analysis indicates the markets follow a Type TODO lifespan, with a median life of TODO months. Risk factors include TODO. With the best model, I generate estimates for the currently-operating markets.

I am interested in websites selling drugs over Tor or i2p, using cryptocurrencies like Bitcoin/Litecoin/Dogecoin, allowing multiple sellers other than the site operators, and providing some sort of escrow functionality. This excludes clearnet sites like Topix, single-vendor shops like Modern Culture or Bungee54, carding shops like Tor Carders Market, hosting services like Cryuserv or Bad Wolf, DNM-focused forums like The Hub, and forums for buyers & sellers to deal directly with each other like The Majestic Garden.

Foreign language markets are excluded because I cannot navigate them1; DrugMarket, Bigshop & a few others are excluded because they reportedly have always been a scam (similarly for most sites listed on the notoriously wrong Hidden Wiki); the Majestic Garden & Underground Market Board 3.0 are excluded because they are forums & do not do escrow for their users; Grand Trunk never left beta & had actual sales.



  • start/end dates are, when possible, the date of the first & last known sales/withdrawals; otherwise they are rounded to my first/last visit to them; or to the start/end of the month they appeared/disappeared
  • closure: whether the shut down was due to law enforcement, precipitated by a hack or de-anonymization, a scam/theft by operators, or voluntary (without known losses to users)
  • arrested: whether the principal operator/owner/maintainer of the marketplace was arrested for running it (this excludes hired staff)
  • multisig: whether 2-of-3 escrow supported; 2-of-2 and other ‘lite’ versions are not considered multisig because they still allow for thefts
  • i2p: whether i2p is used in addition/instead of Tor
  • hacks: number of publicly known hacks resulting in leaks of user information, loss of funds, etc
  • doxed: whether a plausible candidate for site operators has been made publicly known by law enforcement or other people
  • codebase: the origin of the source code for a site where anything is publicly known; ‘custom’ simply means the site operators seem to have written it themselves
  • coin: principal cryptocurrency of marketplace; if multiple coins are accepted, I list the most prominent altcoin
  • guns: whether firearms were sold, specified in rules/policies as allowed to be sold, or rules/policies specified there were no bans on item categories
  • fraud: whether carding items like credit card dumps were sold etc (this does not include fake IDs or informational guides on how to commit fraud; the former have uses besides carding, and the latter are often outdated or just scams)


A table of 87 DNMs (updated 9 June 2019):

Market Start End Alive Closure Arrested URL Multisig I2P Bitcoin Litecoin Dogecoin Darkcoin Codebase Guns Fraud Hacks Doxed Notes
Silk Road 1 2011-01-31 2013-10-02 FALSE raided TRUE silkroadvb5piz3r.onion FALSE FALSE TRUE FALSE FALSE FALSE custom FALSE FALSE 2 TRUE SR1 temporarily sold guns as part of “the Armory” but only for a brief time as sales were poor.
BlackMarket Reloaded 2011-06-30 2013-12-02 FALSE hacked FALSE r6rcmz6lga4i5vb4.onion FALSE FALSE TRUE FALSE FALSE FALSE custom TRUE TRUE 1 FALSE backopy stopped buying on 2 Dec aggravated in part by a big theft, fully shutdown by 23 December. May reopen. BMR permitted gun sales, and also seems to have permitted credit card information sales, judging by angry feedback.
Atlantis 2013-03-26 2013-09-20 FALSE scam FALSE atlantisrky4es5q.onion FALSE FALSE TRUE FALSE FALSE FALSE unknown FALSE FALSE 0 FALSE Atlantis’s shutdown seems, judging by comments & to have initially allowed withdrawals, but disabled it after a few days and then stole the remaining deposits+escrow+vendor-bonds.

I choose 29 Nov as the day where the Sheep scam became irrefutable. Strictly speaking, an operator has not been arrested as of 2015-03-27, but the suspected operator is in legal trouble over money-laundering of large Bitcoin-related sums.
Deepbay 2013-06-30 2013-11-04 FALSE scam FALSE deepbay4xr3sw2va.onion FALSE FALSE TRUE FALSE FALSE FALSE unknown FALSE FALSE 0 FALSE ; based on a , seems to have been almost exclusively drugs.

TM may have used Bitwasp, but it didn’t seem to have Bitwasp error pages and doesn’t really look like the usual Bitwasp DNM.

No official rules on listings were posted before it disappeared, probably because it was unpopular enough that content was not an issue.
BlackBox Market 2013-11-12 2014-02-01 FALSE voluntary FALSE 77yqlxe7pnxhnxvi.onion FALSE FALSE TRUE FALSE FALSE FALSE unknown TRUE TRUE 0 FALSE Interesting site, but not sure it should be listed here. Start date based on . Site stopped responding 1 February 2014. On-site escrow did not use multisig (“We do not make use of the Escrow services provided by Bitcoin itself as this associates buyers and sellers.”) Policies based on the fact that BBM could not know what was being sold on it and so de facto permitted both categories.
GreyRoad 2014-01-04 2014-02-01 FALSE voluntary FALSE greyroaderw4qymd.onion FALSE FALSE TRUE FALSE FALSE FALSE unknown TRUE TRUE 0 FALSE Went public (), operator claims to have been selling for a while but refuses to provide any specifics & very few sellers on market so opening date is used; forums: grforums5qwzbhkl.onion.

It was . Cantina had no stated policies, but it did have a category for guns and given the ‘Data’ categories & general lack of ethics & greed, highly likely would have permitted carding had it not died so ignominiously.

Surviving materials don’t say whether guns were permitted, but given the operator’s it seems more likely than not that carding sales would have been allowed.
BuyItNow 2013-04-30 2014-02-17 FALSE voluntary FALSE buyitnowquyft7dx.onion FALSE FALSE TRUE FALSE FALSE FALSE WordPress TRUE FALSE 0 FALSE Site did not respond on 17 February 2014 or afterwards; no reports on shutdown reason or whether it was a scam.

White Rabbit 2013-12-23 2014-02-01 FALSE scam FALSE rabbittorvr74veg.onion FALSE TRUE FALSE TRUE FALSE FALSE unknown TRUE TRUE 0 TRUE Start date based on . Formerly named “Rabbit’s Marketplace”. Unable to find reports of successful sales on The Hub or Reddit, and WR withdrawal has been broken at least since 21 February 2014; recently. Dead date is based on the February news notice “There are problems with payment gateway”. Forum states only CP is banned (“Items which are not allowed: child porn (and other sick stuff).”) i2p: wrmarket.i2p. IP was found to be leaking.

Unreachable by DeepDotWeb 28 March 2014, and was 19 March 2014. The operator claimed on to have integrated multisig but I can’t find any reports of use of it.

No explicit policies, but UI shows many empty categories but no empty categories for fraud or gun items, so I presume those were not permitted.

Pandora 2013-10-21 2014-08-19 FALSE scam FALSE pandorajodqp5zrr.onion FALSE FALSE TRUE FALSE FALSE FALSE custom FALSE TRUE 2 FALSE See “Forbidden Items on PANDORA”. Pandora has had 2 hacks: the first was a rogue moderator using an admin account, and the second was a loss of half the centralized escrow (repaid by levying extraordinary transaction fees). The operator eventually locked out all seller accounts around 19/20 August 2014 (definitely by 1 September) and disabled withdrawals & the site forums, but continued accepting deposits from buyers; he may also have captured login credentials and robbed accounts on other marketplaces according to several sellers. Targeted in Operation Onymous but had already turned scammer.

Defcon announced the cold wallet had been lost to DPR2, but then that it had been restored. SR2 experienced repeated account balance problems, failed to ever implement autofinalize or dispute resolution (forcing accumulation of orders’ balances), and announced 13 February 2014 that all deposits & escrow had been stolen, followed by another hack in September 2014. Use of SR was not advised. Was raided by Operation Onymous & Defcon arrested.

They claim in it’s custom software; this is confirmed by a leak of PHP source which does not call any frameworks/CRMs. Policies based on no apparent hits among mirrors. it was not an exit scam but a genuine hack.

DNM lifetimes, sorted by when a market opened, colored by how it closed.

I may add to the table other variables; possibly useful ones:

  • 2-factor-authentication
  • Vendor PGP enforced
  • FE status
  • ideology: whether the operator seems ideological (I suspect SR1 may have lasted longer than most post-SR1 markets because Ulbricht’s agorist ideology meant he was not profit-motivated & refused to do an exit scam or shutdown when SR1 was being extorted and may even have been running at loss; but after watching markets in 2014-2015, it seems that such a variable is unlikely to be useful: Ulbricht is the only one clearly ideological, and the rest seem to be aping it or too quiet to tell. Just because the operators say something doesn’t mean they believe it, and many say nothing.)
  • volume (at what time?)
  • how much money was lost when the site scammed or was hacked (only reasonably known for a few scams…)
  • apparent nationality of operator
  • media coverage
  • number of employees (can official claims be trusted?)
  • mandatory role separation (fully-separate buyer/seller/admin/staff accounts)



“The death rate of bitwasp marketplaces will always be higher because it lowers the barrier of entry to starting and launching your own BTC marketplace so less technical people with lesser funds to start the marketplace will use it and that demographic has a higher chance of failure.”

From a predictive standpoint, it doesn’t much matter why Bitwasp correlates with shorter lifetimes - whether it’s through greater likelihood of being hacked or self-selection by weak-willed/poor/uncommitted/incompetent operators. As long as it does, it’ll improve predictions by predicting shorter lifetimes for Bitwasp-using marketplaces, and so it’s less safe for buyers: even if the marketplace is using multisig, there’s still some limited scope for an exit scam; it wastes one’s investment in learning how to use a marketplace; and sellers lose any bond they put up. (Multisig is great and I’ve been advocating for it for a long time, but it’s not a silver bullet.)

In any case, I can try checking if using Bitwasp correlates with being hacked, not just shut down. The sample is currently small enough that the results won’t mean much regardless, though.
