Quantum Risk Moves From Theory to Crypto Roadmaps
Over the next 3-6 months, quantum-resistance becomes a concrete design and custody concern across major chains and institutional custodians, driving opt-in post-quantum schemes and 'long-dormant coin' risk discussion.

Aztec has scheduled a full post-quantum migration by the end of 2030 as part of its proving-system rebuild. That turns quantum risk into a dated item on a production L2's engineering roadmap.

A Nyx Foundation inventory finds no adopted post-quantum plan for Ethereum's consensus-layer peer-to-peer networking. Moving validator signatures to the hash-based leanXMSS scheme would leave that layer unchanged. Aztec has set dates from February to November 2027 to choose its post-quantum primitives ahead of a 2030 migration. Post-quantum work is turning into dated roadmap items and exposing gaps beyond signatures.
