Circle (USDC) Releases Q-Day Roadmap for Blockchains

Circle, issuer of USDC, published a detailed quantum preparation roadmap treating the entire blockchain stack as at risk. Key transitions: TLS 1.3 migration to X25519MLKEM768; replace elliptic curve SNARKs with quantum-resistant STARKs. U.S. and EU are expected to mandate PQC for critical infrastructure by 2030.

For Crypto: The first major stablecoin issuer has set a public timeline. 2030 regulatory mandates will compress the entire DeFi ecosystem's migration window.
