Algorand Foundation published a new post-quantum cryptography roadmap on June 18, laying out protocol work it says is intended to move the network toward broad quantum resilience by the end of 2027.

The plan starts with native post-quantum accounts in a Q3 2026 protocol release. Algorand already supports Falcon signatures through LogicSig programs and the FALCON_VERIFY opcode, but the foundation says native accounts would bring those signatures into ledger support, SDKs, AlgoKit, and wallet tooling. Pera Wallet and legacy SDKs are expected to support Falcon-1024 account derivation in the same release window.

The roadmap also calls for cryptographic agility: support for multiple concurrent signature schemes so Ed25519 accounts can coexist with Falcon-1024, Falcon-512, and potentially other post-quantum schemes as standards mature. Native post-quantum multisig is targeted for the end of 2026, with a focus on institutional operations, treasury controls, and hybrid approval policies that combine classical and post-quantum keys.

Algorand’s remaining work is harder than account signatures. Its Verifiable Random Function and consensus messages still rely on elliptic-curve cryptography, so the foundation says research is underway on a quantum-resistant VRF and signature choices for consensus. A research paper on a candidate VRF is expected in early 2027 if analysis is positive.

The roadmap is not a completed migration. It is a staged plan, and Algorand notes that timing and scope may change as implementations and standards evolve.
