Algorand Reveals Plans to Become Quantum Resistant by 2027

The Proof-of-Stake (PoS) blockchain network, Algorand, has revealed that it is pushing toward becoming quantum-resistant by the end of 2027. The announcement comes as concerns about the post-quantum threat rise in the crypto space.

According to a blog post by the network’s team, the quantum threat has been deemed a serious risk to the security of blockchain technology. Hence, Algorand has outlined a roadmap detailing its efforts, plans, progress, milestones, and ongoing research in the area of post-quantum cryptography (PQC).

Algorand Pushes for Quantum Resistance

Google Quantum AI recently identified Algorand among a set of smart-contract platforms that can achieve PQC. The blockchain already executed its first PQC-secured transaction in 2025 and intends to complete the full PQC transition in less than two years.

The first step in the roadmap is introducing support for native post-quantum accounts in the protocol release scheduled for the third quarter of 2026. Previously enabled Falcon accounts via the Algorand Virtual Machine (AVM) currently demonstrate the viability of post-quantum signatures on the Algorand protocol, but these are not natively supported by the ledger. The introduction of native post-quantum account support will give room for network-level support for multiple concurrent signature schemes.

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

Exploring Post-Quantum Multisignatures

While implementing these upgrades, Algorand intends 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. This will allow for weighted approvals, hybrid combinations of classical and post-quantum signers, and future PQC signature algorithms as standards develop. This step will ensure protection against both classical and quantum-era threats.

Meanwhile, Algorand is not the only blockchain network pushing for quantum resistance in the coming years; Ethereum and Ripple are working towards the milestone as well.
