The DAO is hacked — first on-chain governance crisis
The DAO, a venture-capital-style organization built on Ethereum, had raised $150 million from 11,000 contributors over the preceding weeks. On June 17, 2016, an attacker exploited a recursive-call vulnerability and drained about a third of the funds. The Ethereum community split over what to do: undo the theft via a hard fork (violating 'code is law') or let the theft stand (preserving immutability). They voted, they forked, and the minority who rejected the fork kept the original chain as Ethereum Classic. It was the first time a blockchain community had hit a governance crisis that code alone couldn't resolve.
The hard fork passed with 85 percent support in an informal community poll — not a binding vote, since no such mechanism existed. Ethereum Classic, the holdout chain, still trades. The episode established that even 'trustless' consensus needs some form of social, off-chain agreement to handle crises the rules didn't anticipate.
07 · Networked Consensus
In 2009, Bitcoin proved that thousands of computers that did not trust each other could agree on a shared ledger without any central authority. The mechanism was cryptographic — proof-of-work consensus — and it worked. Since then, DAOs (decentralized autonomous organizations), quadratic voting, liquid democracy, token-weighted governance, and AI-mediated deliberation have each proposed new consensus mechanisms. Most will fail. One or two will compound. The period between 'mass democracy is the only option' and 'mass democracy is one option among several' is being measured in years, not centuries.
