Algorand, a proof-of-stake blockchain network, has announced plans to achieve quantum resistance by the end of 2027. The move addresses growing concerns about the threat quantum computing poses to blockchain security. The network has already executed its first post-quantum cryptography (PQC) secured transaction in 2025 and aims to complete the full transition within two years.
Roadmap to Quantum Security
Algorand's roadmap begins with introducing native support for post-quantum accounts in a protocol release scheduled for the third quarter of 2026. While Falcon accounts have been enabled via the Algorand Virtual Machine, they are not natively supported by the ledger. Native support will allow the network to handle multiple concurrent signature schemes at the protocol level.
After standardizing a new derivation scheme for lattice-based post-quantum keys, Algorand will update its tools, including software development kits, hardware wallets, and AlgoKit. The network will also introduce support for additional signature schemes on traditional Ed25519 accounts. The team emphasized that the migration requires a careful balance, as moving too slowly leaves systems exposed to future quantum attacks, while moving too quickly risks relying on insufficiently tested algorithms.
Post-Quantum Multisignatures and Institutional Use
Algorand plans to deploy native multisig support for multi-cryptographic schemes by the end of 2026, building on its existing multisig capabilities. This is seen as essential for institutional operations, treasury management, and high-stakes financial applications. The final steps involve exploring post-quantum multisignatures as a generic policy layer over independently verifiable signatures, enabling weighted approvals and hybrid combinations of classical and post-quantum signers.
Algorand is not alone in this effort; Ethereum and Ripple are also working toward quantum resistance. The network's approach aims to ensure protection against both classical and quantum-era threats while minimizing protocol disruption.
