The Ethereum Foundation has released a post-quantum computing upgrade roadmap, planning to complete preliminary upgrades before 2029, involving four key hard forks aimed at enhancing network security and supporting quantum computing protection. Quantum computing poses a threat to current public key cryptography, making related work necessary to proceed in advance.

Deep Tide TechFlow News, March 25 — According to DL News, the Ethereum Foundation officially released a roadmap for quantum resistance upgrades on Tuesday. The plan is to complete the initial upgrade of the L1 protocol by 2029, with full execution layer migration to be gradually implemented over the following years.

The roadmap focuses on four key hard forks: “I” fork will provide quantum-resistant public keys for network validators; “J” fork aims to reduce the gas costs for verifying quantum-resistant signatures; these two upgrades are included as candidate options in the Hegota fork expected to launch later this year. “L” fork will compress the blockchain state into zero-knowledge proofs; “M” fork will provide quantum resistance for second-layer networks.

The Ethereum Foundation stated that quantum computing will eventually break the current public key cryptography that secures ownership, authentication, and consensus mechanisms. However, it is estimated that quantum computers capable of cryptographic threats are still 8 to 12 years away. The foundation formed a dedicated quantum research team in January this year and emphasized that “work must begin before the threat arrives.”
