Sorry, I'm not a developer, but I have got a question. It's a little bit off-topic and can't maybe answered easy. As I understand this attack someone renames the transaction ID before being confirmed in the blockchain. Not easy but if he is fast enough it should be possible. With a bit of luck for the attacker the new transaction is added to the block chain and the original transaction is discarded as double-spend. Right? Up to this point the attacker has nothing gained. But next the attacker stressed the Gox support and refers to the original transaction ID. Gox was then probably fooled in such cases and has refunded already paid Bitcoins to the attackers (virtual) Gox-wallet. So far everything is clear. But what I do not understand: Why apparently had so many customers of Gox payment defaults or severely delayed payments? I would imagine that the attacker may have doubled not only his own transaction (maybe for obfuscating the fraud). But then all transfers would still have go through anyway. And a normal customers would have been satisfied. Most people observe only their wallets, I think. What am I missing here? Sorry, is perhaps a silly question. But maybe you can put me on the right track. regards Oliver ------------------------------------------------------------------------------ Androi apps run on BlackBerry 10 Introducing the new BlackBerry 10.2.1 Runtime for Android apps.
