The Algorand blockchain network has announced a detailed roadmap to achieve full quantum resistance by the end of 2027. The plan includes introducing native post-quantum account support in 2026 and exploring post-quantum multisignatures, aiming to protect against future cryptographic threats from quantum computers.
The Proof-of-Stake blockchain network, Algorand, is progressing toward becoming quantum-resistant by the end of 2027. This move addresses rising concerns about the post-quantum threat to blockchain security.
In a blog post, the network’s team deemed the quantum threat a serious risk. The outlined roadmap details its efforts, plans, and ongoing research in post-quantum cryptography.
Google Quantum AI recently identified Algorand among platforms that can achieve PQC. The blockchain executed its first PQC-secured transaction in 2025 and aims to complete the full transition soon.
“Post-quantum migration is a balancing act. 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 team explained. The first step is introducing native post-quantum account support in Q3 2026.
This will allow network-level support for multiple concurrent signature schemes. The network will then implement PQC updates to its software development kits, hardware wallets, and AlgoKit.
“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 stated. They view this as essential for institutional operations and high-stakes financial applications.
One final step explores post-quantum multisignatures as a generic policy layer. This will allow weighted approvals and hybrid combinations of classical and post-quantum signers.
This ensures protection against both classical and quantum-era threats. Other networks like Ethereum and Ripple are also working toward quantum resistance.
