Ethereum's "birthday" is the day mainnet launched (July 30 2015), not the day people started raising money to work on it.

I work for Ethereum at the Ethereum Foundation.

A doodler and computerer. I like permissive/permissionless open source, smart contracts, p2p systems, room-scale VR, and NixOS.

Currently: WhatsABI

Many important dates in the history - but if we're going to pick a birthday, better to celebrate the day the ecosystem shipped something real and kept the promise, not the day a promise was made

Sure, that is when the heart started beating, but some pro-lifers will tell you Ethereum truly began when the whitepaper was published! (Nov 2013)
