Algorand targets full quantum resistance by 2028, launching a multi-year cryptographic overhaul as blockchain networks race to prepare for future quantum threats

NIST finalized ML-KEM, ML-DSA and SLH-DSA in 2024, and Algorand already has quantum-safe State Proofs using Falcon keys rather than starting cold. The painful part is account migration: exposed pubkeys, multisigs, staking keys and wallet UX all have to move before a credible Q-Day, while Ethereum and Solana are still mostly in research/proposal mode. If ALGO lands this by 2027, PQ migration becomes less of a doom thread and more of a chain-health metric.
