NEAR Protocol enables post-quantum ML-DSA signature support on existing accounts without requiring asset migration.
Tech & Launches ·
NEAR Protocol has activated support for post-quantum ML-DSA signatures on existing accounts without requiring users to migrate their assets, according to the protocol. The implementation allows accounts to adopt quantum-resistant cryptography while maintaining their current holdings and account structure.
Post-quantum cryptography addresses the structural vulnerability that blockchains face from sufficiently powerful quantum computers, which could theoretically break the elliptic-curve signatures that secure most blockchain wallets today. The threat is not immediate—current quantum systems lack the error-corrected logical qubits needed to break existing keys—but the cryptographic community warns that adversaries can harvest encrypted transactions now and decrypt them later once hardware matures. ML-DSA, a NIST-standardized algorithm, represents one approach to protecting accounts against this future risk.
The deployment demonstrates a path to post-quantum migration without the coordination overhead of hard forks or forced account upgrades. What remains unclear is the adoption rate among NEAR users and whether other chains will follow a similar in-place upgrade model for signature algorithm support.
