Algorand Releases Quantum-Resistant Upgrade Roadmap, Targeting Full-Chain Quantum Security by 2027–2028

CoinFeed June 20 news, according to CoinDesk, the Algorand Foundation has released a quantum-resistant upgrade roadmap, planning to initiate a series of protocol overhauls in 2026 and achieve overall 'quantum safety' capabilities for the network by late 2027 to 2028, in response to the potential threat of future quantum computing to existing cryptographic systems. The roadmap shows that the first phase will introduce a post-quantum account system, multi-signature wallets, and staking support, followed by gradual upgrades to core protocol components, enabling a comprehensive cryptographic migration from the wallet layer to the infrastructure. It is reported that multiple public chain ecosystems, including the Ethereum Foundation and Solana, have also initiated similar quantum-resistant cryptography research and migration planning.
