Algorand Foundation has released a post-quantum security roadmap that aims to make the layer-1 blockchain broadly quantum resilient by the end of 2027.
Summary
- Algorand plans native post-quantum accounts, multisignatures, and consensus upgrades before its network’s end-2027 target date.
- Google research has increased pressure on blockchains to prepare for future attacks against exposed keys.
- Bitcoin, France, and major security bodies are already planning quantum-safe transitions.
The plan covers user accounts, wallets, developer tools, staking, and the consensus system that helps secure the network.
The foundation said the first milestones will begin in Q3 2026. Native post-quantum accounts are expected to reach users and developers through Pera Wallet and updated software kits. Later steps include post-quantum multisignatures and the foundation’s own treasury migration to post-quantum accounts.
Falcon accounts build on earlier work
Algorand began preparing for quantum risks in 2022 by adding State Proofs signed with Falcon, a lattice-based signature scheme. The foundation says Falcon offers smaller signatures than some other post-quantum options, which can help blockchain systems where data size matters.
The new roadmap expands that work with native Falcon-1024 accounts. Algorand also plans to support hybrid accounts, where users can secure an account with both classic and post-quantum keys. The foundation says this approach can reduce risk while newer cryptography matures.
Algorand said Falcon accounts will work with its standard wallet experience, including familiar mnemonic backup flows. The foundation also said it is open to working with hardware wallet makers and other industry groups on wider account standards.
Quantum risk is moving into policy
The roadmap comes as governments and security agencies move quantum-safe systems into formal planning. France’s cybersecurity agency ANSSI plans to stop certifying products that lack quantum-resistant encryption from 2027. The U.S. National Security Agency has also set a 2027 start date for new national security systems that use approved quantum-resistant algorithms.
Google researchers have added more pressure to the debate. In March, Google said future quantum computers may break the elliptic-curve cryptography used by many blockchains with fewer resources than earlier estimates suggested. Algorand’s Bruno Martins said, “Governments, standards bodies, and security experts around the world are already preparing” for that risk.
Crypto networks prepare early
As previously reported by crypto.news, Glassnode warned that 1.92 million BTC, or 9.6% of supply, sits in outputs that are structurally exposed to a future quantum breakthrough. The firm said the risk is not active today, but exchanges and custodians should improve address practices and plan migration paths.
Crypto.news also reported that France’s 2027 certification rule adds pressure on crypto networks, wallets, and security vendors. Bitcoin, Ethereum, Solana, Algorand, and Aptos are now part of a wider debate on how blockchains should move to post-quantum security.
Algorand’s plan does not claim that a working attack exists. It treats quantum computing as a long-term security issue that needs early work because live blockchains can take years to change.
Chris Peikert, Algorand Foundation’s chief scientific officer, said migrating a live protocol takes years and that the chance of a quantum attack on older cryptography grows as the end of the decade approaches. He said the roadmap brings post-quantum cryptography to every layer of a live network, including consensus.
