Algorand Releases Post-Quantum Upgrade Roadmap, Aiming for Full-Chain Quantum Security by 2027–2028
The Algorand Foundation has officially released its post-quantum upgrade roadmap, planning to initiate a series of protocol modifications in 2026 and achieve full “quantum-resilient” capability across the network by the end of 2027 through 2028—addressing potential future threats posed by quantum computing to existing cryptographic systems. According to the roadmap, Phase I will introduce a post-quantum account system, multi-signature wallets, and staking support; subsequent phases will progressively upgrade core protocol components, enabling comprehensive cryptographic migration—from wallet layers to infrastructure. It is reported that several other public-chain ecosystems—including the Ethereum Foundation and Solana—have also launched similar research and migration initiatives for post-quantum cryptography.
