The U.S. has supported a quantum hardware project worth $300 million, even as Bitcoin and Ethereum approach the need to account for quantum risks. CoinDesk reports this; according to the provided synopsis, the threat has not yet materialized.

According to the same report, the development of fault-tolerant quantum machines and the crypto industry's migration plans are beginning to converge around 2029. The available package does not specify which solutions, organizations, or stages are included in these plans.

The significance of the news lies in the potential reduction of time for crypto networks to prepare for a new class of computational threats. However, since the source is presented only as metadata and a brief synopsis, the scale of U.S. support and the readiness of Bitcoin and Ethereum for migration require further verification.
