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.
