#FakeBTC2010
On August 15, 2010, an unknown attacker exploited a flaw in the Bitcoin protocol known as a "value overflow" bug in block 74638. The bug allowed the creation of 184 billion BTC—far beyond the 21 million supply cap hardcoded into Bitcoin’s rules. This exploit occurred because the code did not correctly check for overflow errors when verifying transactions. Specifically, an attacker was able to send an output with a value so high that it "wrapped around" into a negative number, tricking the software into accepting the transaction.
Immediate Response
Satoshi Nakamoto and other core developers quickly responded.
Within hours, they released a new version (0.3.10) of the Bitcoin software that fixed the vulnerability.
The community agreed to hard fork the blockchain at block 74638, effectively rolling back the invalid transaction and restoring the legitimate chain.
Impact at the Time

At that time, Bitcoin was still a niche experiment.
The price of BTC was less than $0.10, and there were only a few thousand users.
The rapid and transparent response restored confidence among early adopters.
It set a precedent for community coordination and emergency responses.

Strengthening of Code Review and Development
The incident exposed the need for:
Rigorous code audits
Formal peer review processes
A more professional approach to open-source security in crypto
Today, Bitcoin Core undergoes intense scrutiny from a global team of developers. This vigilance is partly due to lessons learned from the 2010 bug.
Security Culture in Blockchain
Other blockchain networks and cryptocurrencies have built their security processes and governance models with this event in mind. The ethos of "don’t trust, verify" was reinforced.
Immutable vs. Mutable Debate
The rollback showed that even Bitcoin’s "immutability" could be bent in extreme cases. It sparked a long-standing debate:
Should blockchains ever be rolled back?
Is consensus more important than code?
