Ethereum Aims for Quantum-Safe L1 by 2029 with Ambitious Multi-Fork Plan

The Ethereum Foundation is working towards making Ethereum quantum-resistant by December 2029. This goal is ambitious, as it aims to reach the same milestone as other major players like Google, Cloudflare, and Microsoft.

To achieve this, the foundation has assessed 62 proposed changes for the Hegotá upgrade, with only two receiving its highest 'must ship' grade. The top proposals are FOCIL, which allows validators to impose requirements on builders, and Frame Transactions, which provides account abstraction and a path towards replacing vulnerable secp256k1 keys.

The foundation has planned a multi-fork approach to achieve quantum resistance across execution, consensus, and data layers by the target date. This involves spreading work across several forks, with developments made alongside changes involving privacy, state management, fast finality, and mandatory execution proofs.
