The user-activated soft fork (BIP 148) takes effect, 2017
1 year ago. BIP 148, the "user-activated soft fork" (UASF), took effect at block 478,484: nodes running it would reject any block that did not signal support for SegWit. Miners were already signalling after a compromise proposal, BIP 91, so no split followed from it.

Bitfinex is hacked, 2016
2 years ago. Hackers stole 119,756 bitcoin, then worth about $72 million, from customer accounts at Bitfinex, a Hong Kong-based exchange, which halted trading. Bitfinex then spread the loss across all its customers, cutting every balance by about 36% and giving them tokens as credit for what they had lost.

The value overflow incident, 2010
8 years ago. A transaction in block 74,638 created about 184 billion bitcoin by exploiting a bug in how the software added up large amounts. Satoshi Nakamoto released a fix, Bitcoin 0.3.10, the same day, and the network replaced the bad block.

SegWit activates, 2017
1 year ago. Segregated Witness (SegWit) took effect at block 481,824. It moves signatures into a separate part of the block, which fixes transaction malleability (the ability to change a transaction's ID before it confirms) and raises block capacity.
