Ethereum Developers Scramble to Meet Quantum Deadline Amid Upgrade Priorities

Ethereum's developers are racing to make the network quantum-resistant by December 2029. This deadline is driving decisions on which upgrades to prioritize, and what features can be cut or delayed.

The Ethereum Foundation's Protocol cluster has deemed its appetite for additional consensus-layer work beyond FOCIL 'close to zero' unless it supports the post-quantum roadmap. FOCIL is a system designed to strengthen transaction-inclusion guarantees, and Frame Transactions, which introduces a new account transaction model, are two of Hegotá's protected headliners.

The trade-off between quantum security and other features is already emerging in Hegotá's scoping process. Quick Slots, which would shorten Ethereum's slot time, sits in B tier despite support from researchers due to concerns about downstream effects on the decoupled-consensus design planned for a later fork.
