The Algorand Foundation has released a post-quantum security roadmap that aims to make layer-1 of the blockchain broadly robust by the end of 2027.
Summary
- Algorand is planning native post-quantum accounts, multisignatures, and consensus improvements ahead of its network’s 2027 target completion date.
- Google’s research has increased the pressure on blockchains to prepare for future attacks against exposed keys.
- Bitcoin, France, and other major security bodies are already planning quantum-safe reforms.
The system includes user accounts, wallets, developer tools, staking, and a consensus system that helps secure the network.
The foundation said the first steps will begin in Q3 2026. Native post-quantum accounts are expected to reach users and developers through Pera Wallet and updated software kits. Recent steps include post-quantum multisignatures and the migration of foundation treasury to post-quantum accounts.
Falcon accounts build on previous work
Algorand began preparing for quantum risks in 2022 by adding Falcon-signed Proof of Empire, a lattice-based signature system. The premise is that Falcon offers smaller signatures than other post-quantum options, which could help blockchain systems where data size is important.
The new roadmap expands on Falcon-1024’s native accounts. Algorand also plans to support hybrid accounts, where users can secure the account with both classical and post-quantum keys. The foundation says this approach can reduce risk while new cryptography develops.
Algorand said Falcon accounts will work with its standard wallet experience, including a standard mnemonic saving flow. The foundation also said it is open to working with hardware wallet makers and other industry groups on account-wide standards.
Quantum risk enters the policy
The roadmap comes as governments and security agencies move quantum-safe systems into formal regulation. France’s cybersecurity agency ANSSI plans to phase out authentication products without quantum-block encryption from 2027. The US National Security Agency has also set a 2027 start date for new national security systems that use quantum-resistant algorithms.
Google researchers added more pressure to the debate. In March, Google said that future quantum computers could break the elliptic-curve cryptography used by many blockchains with fewer resources than previous estimates suggested. Algorand’s Bruno Martins said, “Governments, standards organizations, and security experts around the world are already preparing” for that risk.
Crypto networks are preparing early
As previously reported by crypto.news, Glassnode warned that 1.92 million BTC, or 9.6% of the supply, is sitting on products that are structurally exposed to future quantum breakthroughs. The company said the risk is not active today, but exchange and management should improve address procedures and plan migration methods.
Crypto.news also reported that France’s 2027 certification law is adding pressure to 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 program does not indicate any active attacks. It treats quantum computing as a long-term security problem that requires early work because live blockchains can take years to change.
Chris Peikert, chief scientific officer of the Algorand Foundation, said that migration to a live protocol takes years and that the possibility of quantum attacks on older cryptographies increases as the end of the decade approaches. He said the road brings post-quantum cryptography to all layers of the live network, including consensus.
