I compile a dataset of 87 public English-language darknet markets (DNMs) 2011–2016 in the vein of the famous Silk Road 1, 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.

The most striking aspect of darknet markets (DNMs; online websites selling drugs and other goods using cryptocurrencies), after the fact that they are so successful and exist at all, is how much turnover there is. The casual observer of DNMs will quickly become confused by the sheer number of DNMs over time, and their short lifetimes. How many are there? What predicts longer or shorter lifetimes? Why are they so transient? How do they die? Here I try to shed some light on these questions by tabulating all known launched English-language DNMs from the invention of the business model by Silk Road 1 up through 2016. 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.

Data

Variables:

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)

Table

A table of 87 DNMs (updated 2019-06-09):

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 on Reddit pages & All Things Vice to have initially allowed withdrawals, but disabled it after a few days and then stole the remaining deposits+escrow+vendor-bonds.
Sheep Marketplace	2013-02-28	2013-11-29	FALSE	scam	TRUE	`sheep5u64fi457aw.onion`	FALSE	FALSE	TRUE	FALSE	FALSE	FALSE	Nette	FALSE	TRUE	1	TRUE	withdrawals were halted before 29 Nov, but deposits & sales were ongoing. 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	Disappeared with funds; based on a screenshot of categories, seems to have been almost exclusively drugs.
Budster	2013-10-10	2013-10-20	FALSE	scam	FALSE	`budsterga5hcdxjn.onion`	FALSE	FALSE	TRUE	FALSE	FALSE	FALSE	WordPress	FALSE	FALSE	1	TRUE	https://www.reddit.com/r/Budster/comments/1ove9w/has_anyone_made_a_purchase_yet/ccw8srh https://www.reddit.com/r/DarkNetMarkets/comments/1xyixa/psa_cyruserv_is_down_for_good_budster_taf_hosting/ Budster did not seem to use genuine multisig and this enabled the scam: https://www.reddit.com/r/SilkRoad/comments/1opmha/budster_the_worlds_first_p2p_marketplace/
Project Black Flag	2013-10-14	2013-10-28	FALSE	scam	FALSE	`ajd4yqq7ngzmqo3p.onion`	FALSE	FALSE	TRUE	FALSE	FALSE	FALSE	custom	FALSE	TRUE	1	FALSE	https://www.reddit.com/r/DarkNetMarkets/comments/1peguv/pbf_rip/ ; forums: `blackiiw5nozs6i5.onion`; policies stated on forums (“Prohibited: Weapons, counterfeit money, stolen goods, child pornography, posting other users information, attempt to cause harm, spamming.”)
TorMarket	2013-11-07	2013-12-22	FALSE	scam	FALSE	`tormarkozaegyvco.onion`	FALSE	FALSE	TRUE	FALSE	FALSE	FALSE	unknown	FALSE	TRUE	1	FALSE	Part of the TorMarket user list was leaked by DPR2 on SR2F; TM also admitted other security issues, but further rumors that TorMarket’s shut down was precipitated by a hack by “Profesorhouse” have not been substantiated. 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.
FloMarket	2013-12-01	2014-01-01	FALSE	hacked	FALSE	`fmkt3wixc772jxyj.onion`	FALSE	FALSE	TRUE	FALSE	FALSE	FALSE	Bitwasp			2	FALSE	Apparently hacked 2013-12-20 (previously noted to be hackable); withdrawals began failing on 2014-01-01 & FloMarket announced a second hack on 2014-01-06; for the operator’s explanation, see his interview
Tortuga	2013-12-16	2014-01-05	FALSE	voluntary	FALSE	`tortugauwngwecwd.onion`	FALSE	FALSE	TRUE	FALSE	FALSE	FALSE	Seagull			0	FALSE	Advertised in the SR2F on 2013-12-19; advertised on the BMR forums on 16 Dec. Up on 2014-01-01, down on 2014-01-09 & afterwards. No news about reasons for its closure. 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 Reddit. Site stopped responding 2014-02-01. 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 2013-01-04 (2), 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`. URL stopped working 2014-02-01
Cantina	2014-01-20	2014-02-07	FALSE	hacked	FALSE	`vsudl2g3em6qhcw4.onion`	FALSE	FALSE	TRUE	FALSE	FALSE	FALSE	Nette	TRUE	TRUE	3	TRUE	Cantina spammed vendors on SR2F on 2014-01-20; earliest known mention of the market. It was repeatedly hacked & doxed. 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.
Breaking Bad	2014-02-01	2014-02-06	FALSE	voluntary	FALSE	`breakingnartglxd.onion`	FALSE	FALSE	TRUE	FALSE	FALSE	FALSE	custom	TRUE	TRUE	0	FALSE	Announced on Reddit; site went down 6 February, owner explained shutdown due to “Lack of interest from vendors, constant hate mail, downvotes and claims on security vulnerabilities”
Black Goblin Market	2014-02-03	2014-02-04	FALSE	hacked	FALSE	`ua4aptglh45m5p6b.onion`	FALSE	FALSE	TRUE	FALSE	FALSE	FALSE	Drupal	TRUE	TRUE	0	TRUE	Announced on Reddit; I de-anonymized the site, so it shut down. The “Black Goblin Rules” page does not mention any ban of guns or carding.
Cannabis Road	2014-02-03	2014-02-07	FALSE	hacked	FALSE	`ji4wrifhsnawaw7t.onion`	FALSE	FALSE	TRUE	FALSE	FALSE	FALSE	custom	FALSE	FALSE	1	TRUE	Announced on The Hub; thoroughly hacked & de-anonymized
Utopia	2014-02-03	2014-02-11	FALSE	raided	TRUE	`ggvow6fj3sehlm45.onion`	FALSE	FALSE	TRUE	FALSE	FALSE	FALSE	CakePHP	TRUE	TRUE	0	TRUE	forums: `ysas7uv4drg7rlwv.onion`; forms opened in early January, site opened to ex-BMR sellers late January, general buyers only allowed in February. Dutch seizure notice posted ~7:30AM EST, followed by 5 arrests in Netherlands & Germany
Black Services Market	2013-12-02	2014-02-01	FALSE	scam	FALSE	`thebsm6okkbx7fik.onion`	FALSE	FALSE	TRUE	FALSE	FALSE	FALSE	OSclass	TRUE	TRUE	0	FALSE	Start date based on oldest listing when I checked on 2013-12-26; last admin forum post 18 Jan & PMs to him disabled, reports of escrow problems in late Jan/early Feb, many complaints on forums; site went down 2014-02-14
Red Sun Marketplace	2014-03-20	2014-03-23	FALSE	hacked	FALSE	`redsun4lvjrxwwuy.onion`	FALSE	FALSE	TRUE	FALSE	FALSE	FALSE	Bitwasp	FALSE	TRUE	1	FALSE	Announced on Reddit; hacked (SQli etc); forum: `forumsyccj7ekvvv.onion`. Surviving materials don’t say whether guns were permitted, but given the operator’s interest in recruiting fake ID vendors 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 2014-02-17 or afterwards; no reports on shutdown reason or whether it was a scam. Policies not specified, but many listings for guns, and none of any kind related to carding.
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 Reddit posts. 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 2014-02-21; no one has claimed withdrawals 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.
FreeBay	2013-12-01	2014-02-28	FALSE	voluntary	FALSE	`freebay3yxuebsog.onion`	FALSE	FALSE	TRUE	TRUE	FALSE	FALSE	unknown	FALSE	TRUE	0	FALSE	URL is also apparently `litebay7vp5pm77f.onion` (FreeBay took Bitcoin, LiteBay took Litecoin); open date is guess based on Reddit post; site was not up on 2014-02-28 when I checked. Policies not specified, but many carding & no gun listings.
drugslist	2014-01-08	2014-02-28	FALSE	scam	FALSE	`drugslisvdknitqd.onion`	FALSE	FALSE	TRUE	FALSE	FALSE	FALSE	custom	FALSE	FALSE	1	FALSE	Withdrawals began failing & admin ceased responding in February 2014; date closure to the forum admin account’s last login.
Doge Road	2014-01-18	2014-03-13	FALSE	scam	FALSE	`dogeroadiqt6olb6.onion`	FALSE	FALSE	FALSE	FALSE	TRUE	FALSE	Bitwasp	FALSE	TRUE	0	FALSE	Announced on Reddit; forums: `dogeroadqmu2yzcg.onion`. Went down sometime in March 2014, may have gone bad in late February.
TorEscrow	2014-02-02	2014-04-19	FALSE	scam	FALSE	`torescrow7upglhe.onion`	FALSE	FALSE	TRUE	FALSE	FALSE	FALSE	unknown	FALSE	TRUE	0	FALSE	Initially just an escrow, but TE expanded into a market. Forums: `4rtvonaubslk7vvk.onion`. TE seems to have permitted carding: “We do not allow the sale of weapons, pornography, ebooks, pirated software or hits.”
Armory Vendor Market	2014-02-06	2014-04-07	FALSE	scam	FALSE	`armoryx7kvdq3jds.onion`	FALSE	FALSE	FALSE	FALSE	FALSE	TRUE	Quick.Cart	TRUE	FALSE	1	FALSE	Announced on Reddit; their Cryuserv hosting, according to the hacker, dated back to 2013-05-23 but it’s unclear when they had their first sale. It announced use of Darkcoin in March 2014.
Darknet Nation	2014-02-19	2014-03-01	FALSE	hacked	FALSE	`26a2ueoc3xxrrgs4.onion`	FALSE	FALSE	TRUE	FALSE	FALSE	FALSE	Joomla	TRUE	TRUE	0	TRUE	Announced on Reddit; Q&A. The site leaked its IP address. Down2014-04-03; best guess, shut down sometime in March (the administrator’s last post on The Hub was 2014-03-01.)
Sanitarium Market	2014-02-20	2014-03-28	FALSE	voluntary	FALSE	`sanitarium-market.i2p`	FALSE	TRUE	TRUE	FALSE	FALSE	FALSE	Bitwasp			0	FALSE	Announced on Reddit; long address: `dhd5okd2imkskbhsrlbs5c4nx3cdtmwpplvcei6o3l2sc35kt4ma.b32.i2p`; Tor mirror: `nyu7nlbj33ym2va3.onion`. Unreachable by DeepDotWeb2014-03-28, and last subreddit activity was 2014-03-19. The operator claimed on 2014-02-24 to have integrated multisig but I can’t find any reports of use of it. No surviving info indicates whether weapons or carding were allowed.
Hansa	2014-03-09	2014-03-20	FALSE	raided	TRUE	`hansann7wim5ier2.onion`	FALSE	FALSE	TRUE	FALSE	FALSE	FALSE	Bitwasp	TRUE	TRUE	0	TRUE	Announced on Reddit & de-anonymized; closure date based on last transaction by their IP. They planned to implement multisig but seem to have shut down before it went live. Bitwasp classification based on two comments & screenshot of login page. They appeared to be a voluntary shut down but had been subverted by Dutch police & multisig disabled & turned into a honeypot for monitoring buyer addresses, seller geotagged images, and malware.
EXXTACY	2014-03-23	2014-03-24	FALSE	hacked	FALSE	`j3gwwsnswrg7dtf4.onion`	FALSE	FALSE	TRUE	FALSE	FALSE	FALSE	Drupal			0	TRUE	Announced & de-anonymized on Reddit. No information about policies is available, although since it seems to’ve been run by Sanitarium, it likely had whatever they did. Died before any rules announced or mirrors made.
Mr Nice Guy	2014-03-29	2014-04-20	FALSE	voluntary	FALSE	`niceguymn4plorwb.onion`	FALSE	FALSE	TRUE	FALSE	FALSE	FALSE	Bitwasp	FALSE	FALSE	0	TRUE	Announced on Reddit; forum: `ngforumjj4dkis7w.onion`. IP was leaking.
TorBay	2013-12-18	2014-04-20	FALSE	voluntary	FALSE	`tyedahhf56xli7xp.onion`	FALSE	FALSE	TRUE	FALSE	FALSE	FALSE	hyops	FALSE	TRUE	0	TRUE	Start date based on Reddit announcement; ceased responding in April 2014, after listings had fallen to near-zero.
DarkBay	2014-01-30	2014-05-01	FALSE	voluntary	FALSE	`darkbay4rwgvdkqn.onion`	TRUE	FALSE	TRUE	FALSE	FALSE	FALSE	unknown	FALSE	TRUE	0	TRUE	Announced on Reddit; forums: `7y26aczl3wdyujkc.onion`; formerly, UltraVioletCity/`ultracityi2gdwhq.onion`. “There is very little restriction here, we only ask that you do not sell firearms (rifles, pistols, automatic weapons etc) or child pornography (photographs, videos etc).” Merged with Andromeda?
Pigeon Market	2014-04-14	2014-05-07	FALSE	voluntary	FALSE	`pigeonkcmw5h44lq.onion`	FALSE	FALSE	TRUE	FALSE	FALSE	FALSE	unknown	TRUE	TRUE	0	FALSE	Unknown what happened to funds.
Free Market	2015-01-14	2015-02-26	FALSE	voluntary	FALSE	`tfmarket6iaddx45.onion`	FALSE	FALSE	TRUE	FALSE	FALSE	FALSE	custom	FALSE	FALSE	0	FALSE	Announced on Reddit
Tortuga 2	2014-04-23	2014-06-17	FALSE	voluntary	FALSE	`l6hkncqo46wgzx7y.onion`	TRUE	TRUE	FALSE	TRUE	FALSE	FALSE	Drupal	FALSE	FALSE	0	FALSE	Announced on Reddit; i2p: `wtat6dgz57j5xllu2j7htb7aydq5rgls6edg7e6lf2tumqn5ej3a.b32.i2p`/`tortuga-marketplace.i2p`; multisig; ; unknown what happened to funds.
Deepzon	2014-05-14	2014-07-13	FALSE	voluntary	FALSE	`deepzondhyl3yaro.onion`	FALSE	FALSE	TRUE	FALSE	FALSE	FALSE	unknown	TRUE	TRUE	0	FALSE	Support’s response: “Guns/Weapons are allowed, we thought that would be clear, as we are having the category ‘Weapons’ listed. CC-Dumps are also allowed.”’ ; unknown what happened to funds.
Silk Street	2014-04-08	2014-08-04	FALSE	scam	FALSE	`silkr2xyqsu73qhh.onion`	FALSE	FALSE	TRUE	FALSE	FALSE	FALSE	Bitwasp	FALSE	FALSE	0	FALSE	Announced on The Hub; no reports of withdrawals, so marked false. 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.
Underground Market	2014-04-09	2014-08-26	FALSE	voluntary	FALSE	`unground6baopdio.onion`	FALSE	FALSE	TRUE	FALSE	FALSE	FALSE	Bitwasp	TRUE	TRUE	0	FALSE	Announced on Reddit; forums: `vxcwhb4lzqltfauq.onion`. Shut down citing “not enough customers”.
Cannabis Road 2	2014-03-28	2014-08-25	FALSE	hacked	FALSE	`cannabiskofvl7pa.onion`	TRUE	FALSE	TRUE	FALSE	FALSE	FALSE	custom	FALSE	FALSE	1	FALSE	Forum: `forumzxmoorof4ja.onion`; forum opened 2014-02-26, but site was not operational. The soft-launch/raffle announced 2014-03-28 seems a good start date. Was hacked & lost >$164564.5935166913^₿200₂₀₁₄ from escrow (while multisig was available, very few buyers used it).
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 19/2014-08-20 (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.
Pirate Market	2013-11-29	2014-08-15	FALSE	scam	FALSE	`yjhzeedl5osagmmr.onion`	TRUE	FALSE	TRUE	FALSE	FALSE	FALSE	unknown	TRUE	TRUE	0	FALSE	Start date based on Reddit. Originally RoadSilk; multisig. Site reportedly began blocking withdrawals ~2014-08-15 while still accepting deposits, with the Pirate Market forum being shut down several days later.
Freedom Market	2014-09-16	2014-09-25	FALSE	voluntary	FALSE	`freedom3qg7hmtxn.onion`	FALSE	FALSE	TRUE	FALSE	FALSE	FALSE	Bitwasp	FALSE	FALSE	0	FALSE	Announced on Reddit; went down without notice sometime before 2014-09-25. Site rules: “If the item doesn’t hurt others, you can sell it.”; the categories included “Forgeries” but nothing else, so carding probably counted as ‘hurting others’.
1776	2014-04-19	2014-10-02	FALSE	voluntary	FALSE	`n6tzonxy7sod7eqt.onion`	FALSE	FALSE	TRUE	FALSE	FALSE	FALSE	ASP.NET	FALSE	FALSE	0	FALSE	Announced by DeepDotWeb & on Reddit. Not Bitwasp, given the traceback on error pages. No policy documentation. Disappeared starting 2014-10-03.
Silk Road 2	2013-11-06	2014-11-05	FALSE	raided	TRUE	`silkroad6ownowfk.onion`	FALSE	FALSE	TRUE	FALSE	FALSE	FALSE	custom	FALSE	FALSE	2	TRUE	Forum moderator Cirrus advises considering SR2 compromised (2013-12-22, ironic inasmuch as Cirrus was the LE undercover agent who undid SR2 and helped with SR1); new operators Defcon/Hux/etc deny it. 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 2014-02-13 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.
Hydra	2014-03-27	2014-11-05	FALSE	raided	TRUE	`hydrampvvnunildl.onion`	TRUE	FALSE	FALSE	TRUE	FALSE	FALSE	Bitwasp	TRUE	TRUE	0	FALSE	Announced on The Hub; forum: `hydrafmchvpq5yc6.onion`. Operator arrested in Hungary as part of Operation Onymous. (Apparently unrelated to the Russian Hydra still in operation as of January 2019.)
Cloud-Nine	2014-02-11	2014-11-05	FALSE	raided	FALSE	`xvqrvtnn4pbcnxwt.onion`	TRUE	FALSE	TRUE	FALSE	FALSE	FALSE	Cloud-9	FALSE	TRUE	0	FALSE	Announced on Reddit; on banned items. Raided in Operation Onymous.
Blue Sky	2013-12-03	2014-11-05	FALSE	raided	FALSE	`blueskyplzv4fsti.onion`	FALSE	FALSE	TRUE	FALSE	FALSE	FALSE	unknown	FALSE	FALSE	0	FALSE	Or is the opening 2013-12-12? Raided in Operation Onymous.
TorBazaar	2014-01-26	2014-11-05	FALSE	raided	FALSE	`bazaarlv2a7i3uyn.onion`	TRUE	FALSE	TRUE	FALSE	FALSE	FALSE	Bitwasp	TRUE	TRUE	0	FALSE	Announced on The Hub; original centralized escrow site: `3p42y56a76g6okuv.onion`; forums: `22iwhc2luicynjqy.onion`
Topix 2	2014-03-25	2014-11-05	FALSE	voluntary	FALSE	`topixslhezyytrvm.onion`	FALSE	FALSE	TRUE	FALSE	FALSE	FALSE	custom	FALSE	FALSE	0	FALSE	Started January 2014; opened to public 2014-09-28, previously was invite-only; start date based on first sale listed in recent-feedback page; apparently drug-only based on the listings. Shut down without notice after Operation Onymous.
Alpaca Marketplace	2014-04-20	2014-11-05	FALSE	scam	FALSE	`alpaca727o3c75xx.onion`	TRUE	FALSE	TRUE	FALSE	FALSE	FALSE	unknown	TRUE	FALSE	1	FALSE	Announced on The Hub; policies based on Secret Laboratory writeup Hacked mid-May 2014. Alpaca allows weapons (but not poisons/WMDs/hitmen) and appears to ban carding: “We do not allow items that are advertised as stolen.” Shut down after Operation Onymous (seizure notice) without returning any funds.
Cannabis Road 3	2014-10-06	2014-11-05	FALSE	scam	FALSE	`cannabis37oj24rd.onion`	TRUE	FALSE	TRUE	FALSE	FALSE	FALSE	Alpaca	FALSE	FALSE	0	FALSE	Forum: `forumz2gljo2vhzb.onion`. After CR2 was hacked, developer “Crypto” disappeared; the remaining staff set up a new marketplace hosted by Alpaca Marketplace. Went down with Alpaca after Operation Onymous
Andromeda	2014-04-05	2014-11-18	FALSE	scam	FALSE	`andromedam363aux.onion`	FALSE	FALSE	TRUE	FALSE	FALSE	FALSE	unknown	TRUE	TRUE	0	FALSE	Formerly Silk Road 3/`silkroad3wqdnifp.onion`; site has no connection to SR1 or SR2. Forums: `dvzuhtlteonn6mwd.onion`. Andromeda attempted to mask its exit scam as an Operation Onymous but it wasn’t announced as seized and the broken withdrawals & failed mimicry show it’s bogus.
The Marketplace	2013-11-28	2014-11-09	FALSE	voluntary	FALSE	`themarketplace.i2p`	TRUE	TRUE	TRUE	FALSE	FALSE	FALSE	custom	FALSE	TRUE	0	FALSE	Start date from personal communication; Tor Proxy: `43y5mwjvhxd6zf7v.onion`. The ToS ban CP, guns, and Bitcoin/dollar sales. Site went down 9 November, without any further notice. (The use of multisig means buyers & sellers can still complete the final transactions.)
Onionshop	2014-05-18	2014-09-17	FALSE	hacked	FALSE	`onionshopkue7sxr.onion`	FALSE	FALSE	TRUE	FALSE	FALSE	FALSE		TRUE	TRUE	1	FALSE	Announced on Reddit; hacked 2014-09-17 (announcement, hacker)

Centralized escrow & no reports of deposits being returned.

Closure obscure - staff blames an AWOL developer and the multisig coins to be safe, but a throwaway claims to’ve hacked it.

PHP framework. Site & forums went down 2015-03-18 but large withdrawals began failing ~2015-03-14, marking the start of the exit scam. Former employee claims $58791971.486784644^₿130,000₂₀₁₅ lost.

Disappeared without notice during the post-Evolution chaos & Tor DoS attacks in March 2015; as a centralized market, all escrow & deposits are presumed stolen.

Forums: `kth2mwuwlkezwziy.onion`. Forbidden items are listed on the wiki. BB went down without notice ~2015-05-18, with no communications afterwards; complicating the usual exit-scam story is that none of the bitcoins appear to have moved in weeks and the admin, many months ago, had alluded to serious health issue.

Agora banned guns 2015-07-15 after ~20 gun busts became known; nevertheless, for most of its lifespan it allowed guns. Agora announced 2015-08-25 that it would be going offline indefinitely to deal with Tor deanonymization attacks; withdrawals were enabled and DNstats indicates the site went offline around 2015-09-06.

Site was hacked & user PMs released in 2013; site shut down 2014-07-31 after an attack blame on former admins when “A SESSION-hack was performed and a couple of datasets manipulated but not much damage created”. They claim in an interview 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. Ex-staff insist it was not an exit scam but a genuine hack.

Exit-scammed sometime around October-November 2015; some issues with withdrawals reported in late October, then the site went down for ‘maintenance’ around 2015-11-04, and coins were definitely being moved by the admins by 2015-11-06 .

According to DNstats.net, Crypto Market was last observed up on 2017-02-12, but there are complaints in January 2017 on Reddit so I’m not sure when it really went down. In any case, the escrow funds apparently were not returned.

Multiple staffers were arrested & the site went down for a while but came back up, leading to questions about whether it had been subverted. Last observed by DNstats.net on 2016-10-22. Unclear why it shut down: LE, exit scam, or otherwise? Or to what extent its multisig worked.

EIC went down ~2016-01-01–2016-01-02 for a week or so, then a maintenance message, then came back up but withdrawals failed; finally, went down for good 2016-02-01 according to DNstats.

Still around 2015-07-09 judging from spam for it; may have gone down 2016-05-09 for unclear reasons. No discussion of its closure on Reddit, DDW, The Hub, or I can find in Google.

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)

Analysis

TODO:

“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.
