Circle releases a quantum-safe white paper, outlining the quantum-resistant upgrade path for Arc and USDC.

Deep Tide TechFlow News, May 30th, according to official disclosures from Arc, Circle has released a post-quantum security white paper detailing its roadmap for quantum-resistant security targeting the Arc network, USDC, smart contracts, validators, and infrastructure systems.

The white paper states that as quantum computing capabilities continue to improve, blockchain signature mechanisms, validator key management, smart contract security, and network communication systems may face challenges in the future. To address this, Circle plans to implement post-quantum cryptography technologies in phases.

Specifically, Circle plans to support the SLH-DSA post-quantum signature verification mechanism within the Arc network. During the transition period, USDC smart contracts will continue to be compatible with the existing ECDSA signature interaction method while gradually introducing post-quantum signature capabilities to reduce migration costs and ensure ecosystem compatibility.

Circle indicated that the timeline for fully switching to a post-quantum secure architecture will depend on the ecosystem's readiness, regulatory requirements, and the actual risk assessment results brought by the development of quantum computing. The related roadmap may also be adjusted in the future based on circumstances.
