Bitcoin Mining Reward About To Halve 600

First time accepted submitter ASDFnz writes "The reward for successfully completing a block (also called mining) is about to halve from 50 bitcoins to 25. From the article: 'Bitcoin is built so that this reward is halved every 210,000 blocks solved. The idea is as bitcoin grows the transaction fees become the main part of the reward and the introduction of new bitcoins slows down to a trickle. This also means that there will only ever be 21,000,000 bitcoins in circulation.' You can watch the countdown here."

Bitcoin Exchange BitFloor Says It Will Replace Stolen Coins 117

angry tapir writes "Bitcoin exchanges generally don't seem to recover that easily after security breaches. However, BitFloor, which was hacked and had 24,000 Bitcoins stolen in early September, is coming back online, refunding account holders whose coins were stolen and implementing new security measures, including cold storage for private keys." The key word is "intends" — but I hope it happens as promised.

Bitcoin-Based Drug Market Silk Road Thriving With $2 Million In Monthly Sales 498

Sparrowvsrevolution writes "Every day or so of the last six months, Carnegie Mellon computer security professor Nicolas Christin has crawled and scraped Silk Road, the Tor- and Bitcoin-based underground online market for illegal drug sales. Now Christin has released a paper (PDF) on his findings, which show that the site's business is booming: its number of sellers, who offer everything from cocaine to ecstasy, has jumped from around 300 in February to more than 550. Its total sales now add up to around $1.9 million a month. And its operators generate more than $6,000 a day in commissions for themselves, compared with around $2,500 in February. Most surprising, perhaps, is that buyers rate the sellers on the site as relatively trustworthy, despite the fact that no real identities are used. Close to 98% of ratings on the site are positive."

Hacked Bitcoin Financial Site Had No Backups 331

An anonymous reader writes "A fortnight ago the Bitcoin financial website Bitcoinica was hacked and the hacker stole $87,000 worth of Bitcoins. At the time the owner promised that all users would have their Bitcoins and US dollars returned in full, but one of the site developers has just confirmed that they have no database backups and are having difficulty figuring out what everyone's account balance should actually be. A failure of epic proportions for a site holding such large amounts of money."

Bitcoin Mining Startup Gets $500k In Venture Capital 381

Sabbetus writes "Seattle based Bitcoin startup CoinLab secured a $500,000 investment from various investors such as Silicon Valley firm Draper Associates and angel investor Geoff Entress. CoinLab is an emerging umbrella group for cultivating and launching innovative Bitcoin projects. CEO Vessenes said 'if there is a currency that can trade around the world, it's semi-anonymous, it's instant, it's not controlled by government or bank, what's the total value of that currency? The answer to that is, if it works, it's gotta be in the billions. It just has to be for all the reasons you might want to send money around the world.' This type of talk is common from Bitcoin enthusiasts but apparently seasoned investors are starting to agree. Forbes explains the details of their business plan but in short it has to do with tapping the GPU mining potential of gamers, more specifically gamers of free-to-play games. This would add a new revenue stream for online game companies that are trying to provide free games profitably."
