Dear Blockchain Users:

Recent problems at the Mt.Gox bitcoin exchange appear to be the result of an implementation flaw related to a known bitcoin technical issue. The issue is that of “Transaction Malleability”, a problem in certain implementations that allows an attacker to modify a transaction in such a way as to make the same transaction  appear under a different transaction ID (Tx Hash), without changing any of the internal information (sender, recipient, value etc). This issue first became known in 2011 and it does not affect correctly implemented bitcoin clients, such as the reference client (bitcoind/bitcoin-qt).

The Media & Bitcoin Community Respond to Apple

If you haven’t had a chance to catch up on the past 24 hours of news since Apple removed our app from its App Store, please read on! Our team has been diligently focused on the pouring-in of news, and monitoring the aftermath of Apple’s actions. Our blog (yes, this one!) has received over 52,000 views since our initial response to Apple was posted. We’re happy we’ve got your attention! The response from the Bitcoin community, and media has been overwhelming(ly awesome). Even if Apple never reverses its decision, it’s impossible to deny the magnificent outcry we’ve received from media and Bitcoiners.

Blockchain’s Response to Apple

“Here’s to the crazy ones. The misfits. The rebels. The troublemakers. The round pegs in the square holes. The ones who see things differently. They’re not fond of rules. And they have no respect for the status quo. You can quote them, disagree with them, glorify or vilify them. About the only thing you can’t do is ignore them. Because they change things. They push the human race forward.”Apple, Inc.

Perhaps Apple should have added a disclaimer: “As long as the ‘rebels’ don’t threaten our profit margin”. The rebels no longer run the show at Apple Inc; the beancounters are now firmly in charge.

On Wednesday February 5th, Apple attempted to strike a devastating blow to the bitcoin ecosystem on iOS by removing “Blockchain”, the last remaining bitcoin wallet app, from the App Store. Offering no explanation and no opportunity to address any issues, without any apparent change in circumstances other than the growing popularity of the independent and competitive payment system, Apple has eradicated their payment competition on iOS and left the bitcoin space entirely to competing mobile OSs like Google’s Android.

Blockchain in the Media: December & January

December and January were huge for us. To name a few important things: we acquired the super-sleek and efficient Bitcoin price app ZeroBlock, hit One Million Wallets and ran a 10 BTC giveaway, plus we attended events like CES2014, and the North American Bitcoin Conference.

Our experiences and reflections on #bitcoinmiami

miami13A truly phenomenal gathering of innovation and inspiring energy engulfed Miami Beach during the weekend of January 25-26, for the North American Bitcoin Conference. From the BitPay-sponsored shuttle rides around the city (we sure hope you tipped!), to the words spoken during talks at the Miami Convention Center, the reason why people attended was clear: Bitcoin isn’t going away anytime soon, and it is a technology that offers the ability for each of us to contribute to world-changing potential.
