yes, that link has good info on what happened. The code has been updated to prevent such an attack again. The code can easily be diffed again the latest Bitcoin release to find the differences; no smoke and mirrors here.There are still old nodes out there running out in the wild with the "proof" of what happened. The VBR feature can only be enabled once the network difficulty reaches at least 16 Billion now. This means that there is a healthy amount of mining and the ability of miners to try and mine for the large block payout; not get the large block payout every block like the attacker was able to do with the old code. All exchanges and pools and individuals have had there coin swapped. This version of BitcoinV is ready to stand the test of time now.
