Promote with Leviathan NewsTL; DR summary Circle’s Arc, an EVM-compatible L1 blockchain for stablecoins (USDC gas), has unveiled a phased post-quantum security roadmap to protect against quantum computers breaking current cryptography. At mainnet launch, it adds opt-in SLH-DSA-SHA2-128s wallet signatures. Near-term: quantum-resistant privacy for encrypted state and node comms. Mid-term: offchain upgrades (TLS, data flows). Long-term: validator signatures. This proactive, full-stack plan counters signature forgery and “harvest-now-decrypt-later” attacks across wallets, private contracts, validators, and infrastructure—without forced migrations.
