Google, for example, has warned organizations to begin preparing for the transition to post-quantum cryptography and has integrated quantum-secure cryptographic standards into parts of its infrastructure with a goal of completion by 2029. The US National Institute of Standards and Technology (NIST) has led efforts to standardize post-quantum algorithms and set deadlines for the possible retirement of some existing cryptographic systems.
Within crypto, several major ecosystems have made quantum readiness a strategic priority. The Ethereum Foundation announced a dedicated post-quantum security initiative earlier this year aimed at researching migration paths for blockchain’s vast ecosystem of wallets, applications, and validators. Solana developers also released proposals exploring how users and the network could move to quantum-resistant cryptography if the threat becomes more immediate.
The Algorand Foundation noted that blockchain networks must begin preparing well in advance of “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 this milestone before NIST retires some legacy cryptographic standards and three years ahead of the timeline set by the U.S. National Security Agency for security systems national.
