Ethereum Researchers Find No Adopted Post-Quantum Plan for Consensus-Layer Networking as Aztec Targets a 2030 Migration

A Nyx Foundation inventory finds that replacing validator signatures with the hash-based leanXMSS scheme would not update the peer-to-peer layer, while Aztec has set dates from February 2027 to November 2027 for choosing its post-quantum primitives.

Ethereum's post-quantum work has so far focused on signatures. A new inventory on Ethereum Research by @adust09 of the Nyx Foundation argues that this leaves consensus-layer networking unaddressed, stating it "has no adopted post-quantum mi…
