Algorand releases a quantum-resistant upgrade roadmap, aiming for full-chain quantum security by 2027-2028

The Algorand Foundation officially released a roadmap for quantum resistance upgrades, planning to launch a series of protocol transformations in 2026, and achieve overall "quantum security" capabilities for the network by the end of 2027 to 2028, in response to 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 a gradual upgrade of core protocol components to achieve a comprehensive encryption migration from the wallet layer to the infrastructure. It is reported that several public chain ecosystems, including the Ethereum Foundation and Solana, have also initiated similar research and migration plans for quantum-resistant cryptography.
