Ethereum launches with smart contracts
Ethereum went live on July 30, 2015, adding programmable smart contracts to the blockchain consensus model. Where Bitcoin let you agree on who owns what currency, Ethereum let you agree on any executable rule: voting systems, ownership structures, organizational bylaws, governance mechanisms. Within 18 months, the first Decentralized Autonomous Organizations had raised hundreds of millions of dollars via smart contracts with no managers, no board, no legal jurisdiction. The consensus mechanism was the org chart.
Vitalik Buterin published the Ethereum whitepaper in late 2013 at age 19. The distinction he kept pushing was that Bitcoin consensus proved one specific thing could be agreed on — transaction history — while Ethereum consensus proved that any finite, verifiable rule could be agreed on. Governance became a subset of that.

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.
