Ethereum Hard-Forks to Reverse The DAO Hack

We're posting a thread on an Ethereum story today because of what it settled: how far they went to undo a theft and why Bitcoin has never gone there. Brief thread... 🧵👇

3/9 - The DAO was a decentralized venture fund built on Ethereum, letting anyone pool ether and vote on projects to back. In June 2016 an attacker exploited a bug letting one function call itself recursively before the balance updated, draining funds into…

4/9 - The theft came to roughly $60 million at the time. But the DAO's own rules gave the attacker a 27 day wait before withdrawing anything, and that clock is what turned a hack into a scramble: Ethereum's developers had under a month to decide what to do.
