Leland Yee was arrested yesterday on charges of public corruption, soliciting funds from undercover FBI agents in exchange for promises to aid in a gun-trafficking deal that would have illegally armed Muslim rebels in the Philippines. Yee was one of 26 people charged in the the five-year-long investigation, as was accused murder-for-hire…
In a research paper titled “Bitcoin Transaction Malleability and MtGox” posted to the arXiv archive yesterday, authors Christian Decker and Roger Wattenhofer determined that Mt.Gox could not have lost 850,000 bitcoins through a transaction malleability glitch in the site’s code. Instead, the researchers note that an attack of that scale has never taken place, and…
The venture capital world has been spreading their money around the bitcoin ecosystem in a big way this week.

Are they a…

According to the rules, bitcoin is to be handled as a form of property, rather than currency, meaning bitcoin itself is to be treated like a stock. This puts many bitcoin buyers in the awkward,…
A few days after Mt.Gox filed for bankruptcy protection in Japan, an obscure Twitter user named Eren Canarslan reported that he had heard from an inside source that Mt.Gox had “found” their lost coins. Canarslan later claimed that Mt.Gox CEO Mark Karpeles had confirmed this rumor. Two weeks later, Mt.Gox announced that nearly 200,000 BTC…
