Algorand Aims for Quantum Resistance by 2027

The Proof-of-Stake (PoS) blockchain network, Algorand, has announced its intention to achieve quantum resistance by the end of 2027, a move that comes amid growing concerns about the potential threat of quantum computing to cryptocurrency security.

In a recent blog post, the Algorand team highlighted the significant risk that quantum computing poses to the security of blockchain technology. To address this, the network has laid out a comprehensive roadmap detailing its research, plans, progress, and milestones in the field of post-quantum cryptography (PQC).

Algorand has been recognized by Google Quantum AI as one of the smart-contract platforms capable of implementing PQC. The network has already conducted its first PQC-secured transaction in 2025 and aims to complete its full transition to PQC within the next two years.

“Post-quantum migration is a balancing act,” the Algorand team stated. “Moving too slowly leaves systems exposed to future quantum attacks, but moving too quickly can mean relying on algorithms and implementations that have not yet been sufficiently battle-tested.”

The initial phase of Algorand’s roadmap involves introducing native post-quantum account support in a protocol release scheduled for the third quarter of 2026. While Falcon accounts, previously enabled via the Algorand Virtual Machine (AVM), have demonstrated the feasibility of post-quantum signatures on the protocol, they are not yet natively supported by the ledger. The forthcoming native support will enable network-level compatibility with multiple concurrent signature schemes.

Following the standardization of a new derivation scheme for lattice-based post-quantum keys, Algorand plans to integrate PQC updates across its suite of tools, including legacy software development kits (SDKs), hardware wallets, and AlgoKit. The network will eventually extend support to additional signature schemes for traditional Ed25519 accounts.

Throughout these upgrades, Algorand is committed to fostering an environment that allows for the seamless integration of future advancements with minimal disruption to the protocol.

“Building on our robust history of native multisig, the arrival of cryptographic agility and native post-quantum accounts enables us to deploy native multisig support for multi-cryptography schemes by the end of 2026,” the team explained. “We view this as an essential advancement for institutional operations, treasury management, and high-stakes financial applications.”

A subsequent step in the roadmap will explore post-quantum multisignatures as a generic policy layer, enabling weighted approvals, hybrid combinations of classical and post-quantum signers, and the incorporation of future PQC signature algorithms as they become standardized. This measure is designed to provide robust protection against both current and future quantum-era threats.

Algorand is not alone in its pursuit of quantum resistance; other blockchain networks, including Ethereum and Ripple, are also actively working towards this critical milestone.
