: The Algorand Foundation has released a quantum-resistant upgrade roadmap, planning to initiate a series of protocol upgrades in 2026 and achieve the network's overall "quantum security" capability by the end of 2027 to 2028, in response to the potential threat that future quantum computing poses 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 a gradual upgrade of core protocol components to achieve a comprehensive cryptographic migration from the wallet layer to the infrastructure. It is reported that multiple public blockchain ecosystems, including the Ethereum Foundation and Solana, have also initiated similar research into post-quantum cryptography and migration planning.

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.
