The layer-1 blockchain Algorand has released a plan to update its infrastructure by the end of 2027 to address the potential threat of quantum computing. Algorand Foundation technology chief Bruno Martins stated that the updates aim to provide the network with broad quantum resilience, a threat the foundation has been researching for several years. This move comes as governments, standards bodies, and security experts prepare for a future where quantum computers could break current cryptographic systems. Algorand's roadmap includes new accounts utilizing its Falcon signature scheme, which is designed with quantum-resistant cryptography, and updates to its consensus mechanism. The foundation is also researching options for hybrid accounts that combine classic and quantum-resistant signatures to ensure a smooth transition. Initial upgrades are anticipated in 2026, with full deployment targeted by the end of 2027. Concerns about quantum threats are growing, with other blockchain projects like Ethereum and Solana also exploring solutions, and tech giants like Google setting deadlines for quantum readiness.
