Secp256r1 Precompile Scheduled for Inclusion in Fusaka Upgrade

🌱 ENS Ecosystem Ecosystem Discussion

Update: EIP-7951 (formerly EIP-7212), which introduces a precompile for secp256r1 curve, has been included in the upcoming Fusaka upgrade, tentative June 23, 2025. You can track its inclusion here.

This opens a fascinating design space for ENS. If this implementation lands on L1, no fundamental cryptographic blockers will remain for the following:

  • WebAuthn + ENS login: Authenticate into WebAuthn-supported apps (email, banking, dapps) using ENS name—e.g. sign in as yourname.eth using Face ID or a YubiKey.
  • Onchain DNSSEC + ENS integration: Secure, verifiable domains backed by DNSSEC can be linked to ENS, enabling cross-chain and Web2 ↔ Web3 identity resolution.
  • Enterprise ENS subnames: Issue alice.company.eth tied to a P256-secured device for passwordless access to internal tools, gated dapps, or multi-role DAOs.
  • IoT authentication with ENS: Use ENS to manage and verify identities of constrained devices (sensors, drones, routers) that rely on P256-based crypto stacks.
  • Gov/NGO identity systems: Map national or organizational IDs to ENS in a way that respects existing infrastructure while unlocking composability across Ethereum.
  • Unified identity layer: Reduce cognitive overhead from managing fragmented accounts—anchor all online presence to a single, sovereign ENS identity, verified across Web2 and Web3.

Special note to @ulerdogan and co., I express remorse for having called this initiative a red herring. Your conviction is inspiring, and I’ve learned not to underestimate the long arc of infrastructure work.

Thanks for updating the forum and all! Your and ENSDAO’s support over the last 2 years has been invaluable.
