SUMMARY:24 block rollback
DESCRIPTION:On this day\, versions 0.7 and 0.8 of the Bitcoin reference client software diverged from each other in behavior due to a bug\, causing the block chain to “fork” into two. A fast response from the developers\, community\, miners\, and services orchestrated a rollback of 24 blocks\, preventing a fork in the Bitcoin network.
