Algorand to Be Quantum Resilient by 2027

Algorand has set a roadmap to update its layer-1 network infrastructure by the end of 2027 to address the potential threat posed by quantum computing. Bruno Martins, the Algorand Foundation’s chief of technology, said the work aims to give the blockchain broad quantum resilience after several years of research and preparation.

The plan calls for new accounts built on the Falcon signature scheme, which uses quantum-resistant cryptography. The network will also replace its current, non-quantum-resistant consensus cryptography, change how accounts participating in consensus operate, and is exploring options such as a hybrid mix of classic and quantum-resistant signatures.

Quantum computers remain in early stages, but a March paper from Google researchers suggested they may require fewer resources than previously thought to break blockchain cryptography. That paper also ranked Algorand as likely the most quantum-ready, while noting that Ethereum and Solana are actively exploring their own solutions.
