NEAR Protocol is adding post-quantum cryptography support, allowing accounts to complete key rotation in a single transaction

By: rootdata|2026/05/07 06:42:02

NEAR Protocol stated on platform X that the team is adding post-quantum cryptography support for the network. NEAR's account model is different from btc-42">Bitcoin and Ethereum; accounts are decoupled from cryptography and controlled through rotatable access keys.

The NEAR One team is adding the NIST-approved lattice-based signature FIPS-204 scheme as the first post-quantum signature option. Once launched, any NEAR account holder can rotate keys through a single transaction, achieving quantum safety. NEAR is also collaborating with software and hardware wallets to advance post-quantum support.

Through the chain signature feature, NEAR can provide threshold signatures for over 35 chains. The NEAR Intents team is developing a quantum-safe cross-chain signature solution. If other chains progress slowly in adopting post-quantum cryptography, NEAR can offer a quantum-safe environment. Aspects such as consensus mechanisms, validators, block synchronization, and transaction signatures also need to evolve for the post-quantum era, with the goal of achieving a one-time future-compatible migration.
