Quantum Deadline Forces Ethereum Developers to Prioritize Post-Quantum Features
Ethereum's developers are racing to make the network quantum-resistant by December 2029. This deadline is starting to reshape what gets built next, as they prioritize features that support post-quantum cryptography over other proposals.
The Ethereum Foundation's Protocol cluster said that the deadline will remain non-negotiable at least until a review with outside experts in January, putting optional features into increasingly direct competition with the engineering work needed to harden Ethereum's execution, consensus, and data layers.
Developers are considering moving post-quantum attestations forward from the L* upgrade to K*, while pushing mandatory execution proofs from K* to L*. This swap has not been approved but shows how a threat still regarded as years away is starting to determine which Ethereum upgrades can make the cut today.
