A 10KB on-chain identity and social profile contract with 34 functions for managing name, bio, avatars, covers, topics, colors, and public keys.
Historical Significance
One of the most ambitious early Ethereum contracts. A fully featured on-chain social profile system predating ENS, Lens Protocol, and modern on-chain identity by years. Demonstrates the scope of experimentation in Ethereum's first week.
Context
Deployed during Ethereum Frontier week 1 (August 2015).
