Welcome to episode #7 of The Bitcoin Game, I'm Rob Mitchell.
The white hat hacker known as Johoe ("Yo-ho") rescued over 870 Bitcoins recently from addresses compromised by a temporary bug in Blockchain.info's web wallet. Today I'm honored to introduce Jochen ("Yo-hen"), who works as a computer science researcher at a university in Germany, and is known on BitcoinTalk.org as Johoe. Bitcoin is a hobby Jochen took up in early 2013, as he first discovered the repeated R value issue, due to a 2013 bug in Android's random number generator that affected the security of some Bitcoin wallet apps.
Jochen has literally raced against other hackers to grab Bitcoin in compromised addresses, knowing his opponents have no intention of returning any Bitcoin they grab first.
Aside from this being the first audio interview of Jochen aka Johoe, this is also the first time he tells the Bitcoin world that that it was he who returned 17 Bitcoins to Counterparty, after their Counterwallet had a temporary bug earlier this year that also produced repeating R values.
