Algorand Targets Quantum Resistance by 2027 Amid Crypto Security Concerns

Algorand, a Proof-of-Stake (PoS) blockchain network, has announced its plan to become quantum-resistant by the end of 2027. The move comes as concerns about post-quantum threats rise in the crypto space. Google Quantum AI recently identified Algorand among smart-contract platforms that can achieve Post-Quantum Cryptography (PQC).

Algorand has already executed its first PQC-secured transaction in 2025 and aims to complete the full PQC transition within two years. The network's team emphasized the need for a balanced approach, stating that moving too slowly leaves systems exposed to future quantum attacks, while moving too quickly can mean relying on algorithms and implementations that have not yet been sufficiently battle-tested.

The roadmap for achieving quantum resistance involves several steps, including introducing support for native post-quantum accounts in the protocol release scheduled for Q3 2026. This will allow for network-level support for multiple concurrent signature schemes. The team also plans to implement PQC updates to its tools, such as legacy software development kits (SDKs), hardware wallets, and AlgoKit.
