Today leaders from nine blockchain organisations launched the Quantum Alliance, an open standards body working out what ยซquantum-resistantยป should mean for blockchain networks and how such a claim can be verified. The founding contributors come from Quantus, Postquant Labs, Midnight Foundation, Keystone, AmericanFortress, Intmax, Abelian, Hacken and The Vault, and we are glad to take part through our CRO Bryn Bennett.
The need is easy to see: in May one index ranked Ethereum second among quantum-prepared networks, while another scorecard, counting only cryptography already in production, gives it an F. The Alliance will publish an open definition of readiness, test criteria any team can run against its own implementation and reference designs for migration, with work starting in four groups on migration, post-quantum zero-knowledge systems, wallet security and cross-chain compatibility.
For a custodian this is a practical matter, as the institutions we work with will need to judge the quantum readiness of every network and provider they rely on, ours included, and a shared public standard gives that judgement solid ground as we develop post-quantum custody of our own.
