Near Adds Quantum Security To Testnet

NEAR Protocol Deploys Upgrade 2.13 on Testnet

NEAR Protocol ($NEAR) has deployed upgrade 2.13 on testnet, introducing two significant technical changes: post-quantum safe access keys and dynamic resharding. The release marks a concrete step in NEAR's push to future-proof its cryptographic infrastructure ahead of mainnet deployment.

At the core of the security update is the adoption of FIPS 204, also known as ML-DSA (Module-Lattice-Based Digital Signature Algorithm). The Near One team chose FIPS-204, a lattice-based digital signature algorithm formally standardized by NIST in August 2024 as part of the agency's first batch of post-quantum cryptography standards. ML-DSA was formerly known as CRYSTALS-Dilithium and is designed to be secure against attacks from a cryptographically relevant quantum computer.

NEAR's rotatable access keys are designed to let users shift to quantum-safe signing without changing their account addresses. The upgrade also includes compact key storage and improved epoch sync, reducing overhead for node operators and validators.

Dynamic Resharding Removes Need for Governance Votes

Dynamic resharding means the network can automatically add or remove shards based on demand, rather than operating with a fixed shard count. This removes the need for governance upgrades each time the network needs to scale, allowing $NEAR's infrastructure to respond to load in real time.

The move positions NEAR as an early Layer-1 adopter of post-quantum cryptography, a security-focused protocol update likely to bolster adoption and confidence in the NEAR ecosystem. Mainnet deployment will follow after security audits and coordination with the NEAR community.

The broader context is one of growing urgency. Anton Astafiev, CTO at Near One, warned that the blockchain industry can no longer treat the quantum threat as a distant problem. The upgrade addresses the emerging threat quantum computers pose to current cryptographic standards such as Ed25519 and secp256k1, allowing users to rotate their keys to a quantum-resistant standard in a single transaction.
