Summary

The Algorand Foundation unveiled a roadmap to make its blockchain broadly quantum-resistant during 2027, with plans to introduce post-quantum accounts, multisignature wallets and staking support starting in 2026, before expanding protections to core protocol components.
The announcement comes as crypto networks including Ethereum and Solana ramp up preparations for a future quantum-computing threat.
Algorand notes that migrating live blockchain infrastructure to post-quantum cryptography will take years and must begin well before "Q-Day."
The Algorand Foundation unveiled a roadmap to make its blockchain quantum-resistant by the end of next year, becoming the latest crypto network to outline plans for a future in which quantum computers could threaten the cryptographic systems underpinning digital assets.
The roadmap identifies a series of upgrades beginning in 2026, including the introduction of post-quantum accounts, multisignature wallets and staking support. Later phases will focus on more fundamental components of the network.
The announcement
reflects a growing recognition across the crypto industry
that transitioning to quantum-resistant cryptography could take years, requiring changes not only to user wallets but also to core protocol infrastructure.
Most major blockchains today rely on elliptic curve cryptography, which secures wallets and transactions, but is widely believed to be vulnerable to sufficiently advanced quantum computers. While experts generally agree that such machines do not yet exist, governments, technology
companies and crypto projects have increasingly begun
planning for a long-term migration.
Google, for example, has warned organizations to begin preparing for the transition to post-quantum cryptography and
has been integrating quantum-safe cryptographic standards
into parts of its infrastructure with a 2029 completion target. The U.S. National Institute of Standards and Technology (NIST) has
been leading efforts to standardize
post-quantum algorithms and has set timelines for the eventual retirement of certain legacy cryptographic systems.
Within crypto, several major ecosystems have elevated quantum preparedness as a strategic priority. The Ethereum Foundation
earlier this year announced a dedicated post-quantum
security initiative aimed at researching migration paths for blockchain's vast ecosystem of wallets, applications and validators. Solana developers
likewise published proposals
exploring how users and the network could transition to quantum-resistant cryptography if the threat becomes more immediate.
The Algorand Foundation noted that blockchain networks need to begin making preparations well before a so-called "Q-Day," the hypothetical moment when a quantum computer becomes capable of breaking the cryptography currently used to secure digital assets.
The foundation said its roadmap builds on work it began in 2022, extending those efforts to the rest of the protocol, with the goal of achieving what Algorand describes as broad quantum resilience by the end of 2027. The foundation said it expects to reach that milestone before NIST retires certain legacy cryptographic standards and three years ahead of a timeline set by the U.S. National Security Agency for national security systems.
"Migrating a live protocol takes years, and the probability of a quantum attack on legacy cryptography grows meaningfully as the end of this decade approaches," said Chris Peikert, the chief scientific officer at the Algorand Foundation.
