Circle released the "Post-Quantum Security White Paper," proposing a phased post-quantum resilience roadmap focused on the long-term security of the Arc blockchain ecosystem.
The roadmap covers multiple technical directions, including quantum secure signatures, private execution environments, validator hardening, infrastructure migration, and account recovery, applicable to core components such as the Arc network, USDC, smart contracts, and validators.
Circle stated that it plans to provide post-quantum signature support when the Arc mainnet launches (in 2026) to enhance the ecosystem's ability to respond to future quantum computing threats.
