Bitcoin block 74638 was mined in 2010, this block was responsible for the 184 billion Bitcoin bug! Billions of Bitcoin minted out of thin air.

This block was responsible for the Value Overflow Incident otherwise known as the '184 Billion Bitcoin bug'. It created 184,467,440,737.09551616 bitcoins that were split equally sending 92233720368.54277039 bitcoin to two addresses. This was possible because the code used for checking transactions before including them in a block didn't account for the case of outputs so large that they overflowed when summed. A new version of the bitcoin client was published within five hours of the discovery that contained a soft forking change to the consensus rules that rejected output value overflow transactions (as well as any transaction that paid more than 21 million bitcoins in an output for any reason).

The bug was spotted very quickly on the Bitcoin talk forum and corrected within 5 hours of finding out the bug. The hacker is still unknown with no one hearing of them ahain. The devs then soft forked the blockchain, which reset it to before the exploit was done. The update was actually implemented by Satoshi himself!

This got me thinking, if this bug happens in 2023, 5 hours is more than enough for the bad actors to dump all the Bitcoin and dry up all the liquidity from the market before anything can be done about it imo.
