[Algorand Releases Quantum-Resistant Upgrade Roadmap, Targeting Full Quantum Security by 2027–2028] According to Coindesk, the Algorand Foundation has released a quantum-resistant upgrade roadmap, planning to initiate a series of protocol modifications in 2026 and achieve full network 'quantum security' capabilities by the end of 2027 to 2028. This is aimed at addressing the potential threats posed by future quantum computing to existing cryptographic systems. The roadmap indicates that the first phase will introduce post-quantum account systems, multi-signature wallets, and staking support, followed by gradual upgrades to core protocol components to enable a comprehensive cryptographic migration from the wallet layer to the infrastructure level. It is reported that other public chain ecosystems, including the Ethereum Foundation and Solana, have also launched similar quantum-resistant cryptography research and migration plans.
