How to Disincentivize Large Bitcoin Mining Pools
Bitcoin has stared down an existential threat, after a consortium of miners briefly gained enough processing power to theoretically destroy the currency. For a few hours on Friday, mining pool Ghash. If it had abused that power, it would have had the ability to indirectly take money from other users, for instance by buying something and then rewriting history so that the purchase never happened.
But shortly after the threshold was breached, some members of the mining pool pulled their computing power from the group, averting — or at least, delaying — catastrophe. The bitcoin network runs with the aid of peer participants performing a function called "mining", which involves spending large amounts of processing power in order to verify transactions as accurate. Miners are given financial rewards for doing so, and since there are so many of them, it is typically impossible to force a fake transaction into the bitcoin ledger: more than half the processing power of the network would need to verify the fake transaction.
But many miners lump their processing power together, in "pools" such as Ghash, in order to increase the chances of getting rewards. While that makes financial sense for any individual miner, it has long posed the threat of ending the decentralised aspect that makes bitcoin so popular.
It's not the first time the "impossible" attack on bitcoin has been scarily close. Those steps were apparently insufficient. That has led some experts, such as Andreessen Horowitz's Chris Dixon, to dub the problem "a minor issue. The real protection isn't technology but economics. Google goes one step further, treating bitcoin identically to conventional currencies, offering users a selection of news headlines alongside the latest price. Both firms are several months behind Microsoft, which added bitcoin to its Bing finance product in February , and even the normally-measured financial types at Bloomberg, which included the cryptocurrency in February.
Tellingly, neither Google nor Yahoo's press offices were aware the changes had been made when the Guardian contacted them, though Google later responded to say "we're always working to provide more of the financial data people are looking for. On Monday, the first bitcoin apps to take advantage of Apple's new rules allowing cryptocurrencies on the app store began to appear.
Coinpocket was previously only accessible as an HTML5 web app, to get around the restrictions, but now the wallet app, which lets users spend and receive their bitcoins, is relaunched as a native iPhone app. The new version also includes the ability to spend bitcoin by scanning QR codes.
Perhaps more importantly, apps which let users spend bitcoin for digital goods have also turned up on the app store. Betcoin and eGifter both allow bitcoin purchases, the former as part of a simple betting game and the latter for gift cards. While the apps might still be pulled by Apple after the fact, their existence on the App Store could signal another major change in direction from the company.

The existential threat to bitcoin its boosters said was impossible is now at hand
By Chris Baraniuk. Bitcoin is booming. Jonathan Levin at the University of Oxford runs Coinometrics. Since the record of all Bitcoin transactions is public, Levin has used it to gather data about the distribution and movement of bitcoins. Levin is concerned that if the owners of those large, idle hoards suddenly started making lots of transactions or cashing in, it could lead to a lack of confidence in the Bitcoin economy.
The Terror of Mining Pool Centralization
NEW YORK The Bitcoin digital currency system is in danger of losing its credibility as an independent payment system because of the growing power of a group that runs some of the computers behind it. In recent weeks, a British-based "mining pool" called GHash has amassed nearly half of the Bitcoin computing power and has briefly gone over 50 percent. Miners operate the computers that keep track of bitcoins and create additional coins. Miners pool their computing power to spread the financial risk of their operations. If GHash amasses more than half of the computing power devoted to Bitcoin, it could in theory control the flow of transactions, freeze people out of the network and keep all future bitcoins for itself.
