TechFlow reports that on June 18, the Algorand Foundation officially released its post-quantum upgrade roadmap, planning to initiate a series of protocol modifications in 2026 and achieve full “quantum security” across the network by the end of 2027 through 2028, in response to potential future threats posed by quantum computing to existing cryptographic systems. According to the roadmap, the first phase will introduce a post-quantum account system, multi-signature wallets, and staking support; subsequent phases will progressively upgrade core protocol components to enable comprehensive cryptographic migration—from the wallet layer to infrastructure. It is reported that several other public blockchain ecosystems—including the Ethereum Foundation and Solana—have also launched similar research and migration initiatives for post-quantum cryptography.
