As Silk Road emerged from the "dark-web", other sites have appeared offering services that are frowned upon by most. As Forbes reports, perhaps the most-disturbing is "The Assassination Market" run by a pseudnymous Kuwabatake Sanjuro. The site, remarkably, a crowdfunding service that lets anyone anonymously contribute bitcoins towards a bounty on the head of any government official–a kind of Kickstarter for political assassinations. As Forbes reports, NSA Director Alexander and President Obama have a BTC40 bounty (~$24,000) but the highest bounty - perhaps not entirely surprising - is BTC 124.14 (~$75,000) for none other than Ben Bernanke. Sanjuro's raison d'etre is chilling, "as a few politicians gets offed and they realize they’ve lost the war on privacy, the killings can stop and we can transition to a phase of peace, privacy and laissez-faire."

As Bitcoin becomes an increasingly popular form of digital cash, the cryptocurrency is being accepted in exchange for everything from socks to sushi to heroin. If one anarchist has his way, it’ll soon be used to buy murder, too.

...

For now, the site’s rewards are small but not insignificant. In the four months that Assassination Market has been online, six targets have been submitted by users, and bounties have been collected ranging from ten bitcoins for the murder of NSA director Keith Alexander and 40 bitcoins for the assassination of President Barack Obama to 124.14 bitcoins–the largest current bounty on the site–targeting Ben Bernanke, chairman of the Federal Reserve and public enemy number one for many of Bitcoin’s anti-banking-system users. At Bitcoin’s current rapidly rising exchanges rate, that’s nearly $75,000 for Bernanke’s would-be killer.

...

Sanjuro’s grisly ambitions go beyond raising the funds to bankroll a few political killings. He believes that if Assassination Market can persist and gain enough users, it will eventually enable the assassinations of enough politicians that no one would dare to hold office. He says he intends Assassination Market to destroy “all governments, everywhere.”

“I believe it will change the world for the better,” writes Sanjuro, who shares his handle with the nameless samurai protagonist in the Akira Kurosawa film “Yojimbo.” (He tells me he chose it in homage to creator of the online black market Silk Road, who called himself the Dread Pirate Roberts, as well Bitcoin inventor Satoshi Nakamoto.) ”Thanks to this system, a world without wars, dragnet panopticon-style surveillance, nuclear weapons, armies, repression, money manipulation, and limits to trade is firmly within our grasp for but a few bitcoins per person. I also believe that as soon as a few politicians gets offed and they realize they’ve lost the war on privacy, the killings can stop and we can transition to a phase of peace, privacy and laissez-faire.”

...

Like other so-called “dark web” sites, Assassination Market runs on the anonymity network Tor, which is designed to prevent anyone from identifying the site’s users or Sanjuro himself.

...

As for technically proving that an assassin is responsible for a target’s death, Assassination Market asks its killers to create a text file with the date of the death ahead of time, and to use a cryptographic function known as a hash to convert it to a unique string of characters.

...

“I am a crypto-anarchist,” Sanjuro concludes. “We have a bright future ahead of us.”
