> There's no such thing as a trivial change to the bitcoin consensus rules, especially when that change requires everyone to upgrade their software at once on pain of financial loss. We're talking something that's never been done before in the entire history of Bitcoin.
You mean... like this? https://en.bitcoin.it/wiki/Value_overflow_incident https://en.bitcoin.it/wiki/Value_overflow_incident
- makomk 9y agoNo, not like that. Technically that only required a supermajority of miners to install the fixed version (and everyone to stop trading temporarily, but there wasn't much of that going on back then anyway). This would be harder because it really would require everyone to upgrade. BIP50 is probably closer; that did require everyone to upgrade over a relatively short timespan or work around the issue by changing a setting, ironically enough due to a latent bug triggered by increasing block size closer to the maximum 1MB.

While the transaction does not exist anymore, the 0.5 BTC that was consumed by it does. It appears to have come from a faucet and has not been used since.[7] Wait... so if you wait long enough then old transactions disappear ? I thought the whole blockchain could allow anyone to track every transactions ?
