Eleven years of Ethereum

Ethereum turns 11. Come celebrate. On July 30, 2015, the Ethereum mainnet went live. Eleven years later, we are throwing it a birthday party. Ethereum Eleven is a one-night celebration of the network and the people who build on it. No panels, no pitch decks. Just builders, founders, researchers, and old friends in one room with food, drinks, music, and a birthday toast. If you have shipped onchain, helped someone else ship, or just want to mark a decade-plus of Ethereum with the Bay Area community, you belong here. When: Thursday, July 30, 2026 Where: SECRET LOCATION, San Francisco Cost: Free to attend. RSVP required, space is limited.
