ChainCatcher report: The NEAR public blockchain official posted on X that cryptographic agility is a foundational requirement for the blockchain industry, and signature scheme upgrades should become routine. NEAR accounts now support the post-quantum ML-DSA signature scheme without requiring asset migration. The NEAR core development team, Near One, is advancing NEP-655—a proposal involving commitment-based implicit accounts derived from initial state hashes, where assets reside after the hash, without exposing public keys or key hashes on-chain. The related functionality is already live on the testnet, with a mainnet launch planned for the coming weeks. For developers, the team is designing the NEAR Intents wallet contract to support custom signature extensions, including ML-DSA and hash-based schemes. For chains that currently cannot add post-quantum keys, the team is implementing a Q-day recovery registry on NEAR, allowing users to submit recovery keys in the form of rotatable hashes. NEAR states that quantum computing considerations were already factored into its design in 2018.

Summary
NEAR, a public blockchain, has announced support for the post-quantum ML-DSA signature scheme in its accounts without requiring asset migration. NEAR’s core team, Near One, is developing NEP-655 to enable commitment-based implicit accounts derived from initial state hashes. The update is now live on testnet, with a mainnet rollout coming soon. Developers are also building the NEAR Intents wallet contract to support custom signature extensions, including ML-DSA and hash-based schemes. NEAR is launching a Q-Day recovery registry for blockchains not yet quantum-ready. Quantum resistance has been a consideration in NEAR’s blockchain development since 2018. Smart contract development teams are currently testing the new features ahead of the mainnet launch.
