Summary
This ERC proposes a standard interface for Persistent Identity Tokens — ERC-721 tokens that represent human-readable, on-chain identities bound to EVM addresses.
Three Interface Layers
IPersistentIdentity) — name registration, address binding, URL records, and soulbound lockingIPersistentIdentityResolver) — on-chain name-to-address and identity lookupIPersistentIdentityPolicy) — namespace governance (pricing, renaming, unbinding, reserved names)Core Mechanism: Bind-to-Lock
Tokens are freely tradable when unbound. When a user binds an identity to their address (
bind(tokenId)), the token becomes soulbound — protecting active identities from unauthorized transfer while allowing a secondary market for unclaimed names.Key Differentiators from Existing Standards
Reference Implementation
PEG ID — live on Pentagon Chain (chain ID 3344) at
0xf97EB9f8293D1FD5587a809Eb74518c300738d07with 2,200+ identities minted.Protocol Repository
