Circle Unveils Post-Quantum Roadmap for Arc Blockchain
Share:
Circle (USDC issuer) published a post-quantum roadmap for its Arc Layer‑1 blockchain, committing to cryptographic resilience across the stack and introducing opt-in post‑quantum wallet signatures. Experts warn quantum computers could break public‑key cryptography by 2030 or sooner, prompting Circle to act preemptively to protect crypto security, DeFi/CEX infrastructure and user keys. Arc will launch with opt‑in post‑quantum signatures and no forced network migration, reducing migration risk and supporting secure adoption and token launch credibility.
