Algorand Races Against Quantum Threat with Post-Quantum Roadmap

Algorand, a Proof-of-Stake blockchain network, is working to become quantum-resistant by the end of 2027. The goal comes as concerns about post-quantum threats rise in the crypto space.

The project's team has outlined a roadmap detailing its efforts and plans to achieve this goal. According to the plan, the first step will be introducing native post-quantum account support in the third quarter of 2026. This will allow for network-level support for multiple concurrent signature schemes.

After establishing a clear direction for standardizing a new derivation scheme for lattice-based post-quantum keys, Algorand will implement PQC updates to its tools, including legacy software development kits (SDKs), hardware wallets, and the AlgoKit. The network will eventually introduce support for additional signature schemes on traditional Ed25519 accounts.

The team aims to create an environment that enables the integration of future advances with minimal protocol disruption. One of the final steps in the roadmap explores post-quantum multisignatures as a generic policy layer over independently verifiable signatures, allowing for weighted approvals and hybrid combinations of classical and post-quantum signers.
