The Bitcoin Foundation discovers the limits of anarchy
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. This article is more than 7 years old.

Bitcoinference Summer 2014 Amsterdam
A t the Black Blockchain Summit, there is almost no conversation about making money that does not carry with it the possibility of liberation. This is not simply a gathering for those who would like to ride whatever bumps and shocks, gains and losses come with cryptocurrency. It is a space for discussing the relationship between money and man, the powers that be and what they have done with power. Online and in person, on the campus of Howard University in Washington, D. What they are is a cross section of the world of Black crypto traders, educators, marketers and market makers—a world that seemingly mushroomed during the pandemic, rallying around the idea that this is the boon that Black America needs. And this summer, when the popular money-transfer service Cash App added the option to purchase Bitcoin, its choice to explain the move was the MC Megan Thee Stallion.

We were stunned and thrilled to meet so many active Amsterdam bitcoiners. Apparently, up to people participated over the course of the evening at Cafe Stanislavski on Leidseplein! We got a chance talk to PikaPay about their recent achievements. Also Bitonic , who are based in Driebergen, shared some exciting insights on their next steps. We cannot disclose it here, but can assure you that it will be a great step forward for bitcoin in the Netherlands! The crowd was very international with participants from all over Europe and the U. We had good discussions on bitcoin mining or the difficulty thereof , and about altcoins. I have personally taken a more negative stance towards most altcoins, especially the ones which are not offering no clear distinctive features compared to bitcoin, but opinions were mixed. We had a lively discussion on this topic.

One of them was the Bitcoin international conference that took place from Thursday 15th to Saturday 17th of May report on this will follow soon on the MoneyLab blog. Jolien Siemerink attended the congress and wrote a detailed report of how it went. She attended the congress with a professional interest — as her company recently started accepting Bitcoins as payment — as well as a personal interest — to hear what Bitcoin is all about from different speakers. I started the day as what veteran Internet users would call a Newbie. Even though I am well educated in new media and digital cultures and, of course, on a personal level very experienced in online shopping, I have never bought anything with Bitcoins. Mostly because I thought it would blow over. Was I that wrong?

It is from this perspective that the EBA issued its warning on virtual currencies in December A cross-sectoral working group of European supervisors is now looking at whether to further regulate virtual currencies.
