Lessons from 10 Years of the Ethereum Identity Stack

Talkat ETHConf 2026 · 2026-06-08..06-10· [security, web-platform]

History and practical lessons from a decade building the stack: ENS starts development in 2016 and launches 2017 and by 2021 becomes ENS is a username and profile, proving wallets plus DNS-like names drive adoption; EIP-4361 Sign-in with Ethereum provides a decentralized SSO supported in major wallets; the Ethereum Follow Protocol runs an onchain social graph with tens of thousands of users; ethidentitykit.com is a React library wiring these parts. Identity is 20 hard problems unbundled so each part can stand or fall independently.
