Crypto firms launch quantum alliance to set quantum-ready tests

The Alliance says 6.04 million BTC, about 30% of supply, are exposed unless networks, wallets and bridges adopt shared tests and migration rules.

Executives from a group of blockchain firms launched the quantum alliance on Thursday, an open standards body to define what counts as “quantum-ready” and how to test it across networks, wallets and infrastructure, according to the report. Founding contributors named in the report include Quantus, Postquant Labs, Midnight Foundation, Keystone, Abelian and others.

Modeled on the Internet Engineering Task Force, the Alliance said proposals will advance on public evidence and working implementations rather than corporate size or token holdings, and that it will publish its outputs openly. Its work will run in four groups: blockchain migration, post-quantum zero-knowledge systems, wallet security and cross-chain compatibility. “In the future, ‘post-quantum cryptography’ will just be called ‘cryptography’ and everything else will be in a museum,” said Quantus founder and CEO Christopher Smith.

The Alliance framed its mandate around a specific risk the report describes: most blockchains use elliptic-curve signatures, and once an account’s public key is revealed on a ledger, a sufficiently powerful quantum computer running Shor’s algorithm could in theory derive the private key and seize funds. By the Alliance’s count, roughly 6.04 million BTC, about 30% of supply, sit quantum-exposed at rest.

Its four workstreams map onto where keys and proofs live in practice: base-layer upgrades to swap cryptography, proving systems that underwrite privacy and scaling, signing devices and wallet software, and the cross-chain links where assets and messages move. That creates a path for holders with already-exposed keys, and for stablecoin issuers, bridge and oracle operators, and governance contract admins the report mentions, to test against the same yardstick as networks begin migrating.

The timelines the Alliance cites in the report point toward the late 2020s, including research from contributors and outside studies. No machine can do it yet, but the report notes that key bottlenecks are being chipped away in published work.

The report also says industry efforts are broadening beyond this standards push. Coinbase recently urged Bitcoin developers to begin preparing a quantum migration that could take years, and a consortium backed by BlackRock, Strategy and Coinbase has committed funding.

The Alliance’s next step is to turn those four tracks into shared test suites and migration rules that networks and wallet teams can implement. Everything it produces, it said, will be published openly.
