Gate News reports that on March 25, the Ethereum Foundation officially released a roadmap for quantum-resistant upgrades. The plan is to complete the initial upgrade of the L1 protocol by 2029, with full execution layer migration gradually progressing over the following years. The roadmap focuses on four key hard forks: “I” fork will provide the network validators with quantum-resistant public keys; “J” fork aims to reduce the gas costs for verifying quantum-resistant signatures; these two upgrades are included as candidate options for the Hegota fork expected later this year. “L” fork will compress the blockchain state into zero-knowledge proofs; “M” fork will provide quantum resistance for layer 2 networks. The Ethereum Foundation states that quantum computing will eventually break current public key cryptography used for ownership, authentication, and consensus mechanisms, but it is estimated that quantum computers capable of cryptographic threats are still 8 to 12 years away. The foundation established a dedicated quantum research team in January this year and emphasizes that “related work must begin before the threat arrives.”
