Every major chain is racing quantum at once
@Algorand shipped post-quantum accounts inside the protocol with v5.0.0 this week.
@StellarOrg published a three-stage plan that adds quantum-safe verification to Soroban this year and first-class signers on classic accounts in 2027.
Vitalik Buterin moved quantum safety up Ethereum's roadmap on August 10, Sei proposed SIP-5 for quantum-resistant accounts, and Mysten Labs is building quantum-hardened cards for $SUI wallets.
