Algorand reveals plans to become quantum-resistant by 2027

Algorand hopes to provide protection against classical and quantum threats by exploring post-quantum multisignatures as a generic policy layer.

Proof-of-Stake (PoS) blockchain network, Algorand, has revealed that it is working to become quantum-resistant by the end of 2027. The announcement comes amid concern about the rising post-quantum threat in the crypto space.

According to a blog post written by the network team, the quantum threat has been considered a serious risk to the security of blockchain technology. Therefore, Algorand presented a roadmap detailing its efforts, plans, progress, milestones and ongoing research in the field of post-quantum cryptography (PQC).

Algorand pushes for quantum resistance

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

“Post-quantum migration is a balancing act. Evolving too slowly exposes systems to future quantum attacks, but evolving too quickly can mean relying on algorithms and implementations that have not yet been sufficiently tested,” the Algorand team explained.

The first step in the roadmap is to introduce support for native post-quantum accounts in the protocol release scheduled for Q3 2026. Falcon accounts previously enabled via the Algorand Virtual Machine (AVM) are currently demonstrating the viability of post-quantum signatures on the Algorand protocol, but these are not natively supported by the ledger. Introducing native support for post-quantum accounts will pave the way for network-level support for multiple, simultaneous signing schemes.

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

Exploring post-quantum multisignatures

When implementing these upgrades, Algorand intends to create an environment that allows the integration of future advancements with minimal disruption to the protocol.

“Building on our strong history of native multisig, the arrival of crypto agility and native post-quantum accounts allows us to deploy native multisig support for multi-crypto schemes by the end of 2026. We see this as a critical advancement for institutional operations, treasury management, and high-stakes financial applications,” the team explained.

One of the final steps in the roadmap explores post-quantum multisignatures as a generic policy layer versus independently verifiable signatures. This will enable weighted approvals, hybrid combinations of classical and post-quantum signers, as well as future PQC signing algorithms as standards develop. This step will guarantee protection against classical and quantum threats.

Meanwhile, Algorand is not the only blockchain network promoting quantum resistance in the coming years; Ethereum and Ripple are also working to achieve this milestone.
