2013-10-302019-06-09 in progress certainty: 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.

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.



  • 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 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.

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://old.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

Dutch seizure notice posted ~7:30AM EST, fol­lowed by 5 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. Down 2014-04-03; 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 Deep­DotWeb 2014-03-28, 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.

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 >$123,384 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 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’.

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.

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.
