Bitcoin's Quantum Race: $300M US Push Targets 2029 Threat Window

A $300 million US government hardware push is accelerating fault-tolerant quantum computing development, with both Bitcoin and Ethereum's security assumptions converging on a critical 2029 window where current cryptography could theoretically be broken.

While the quantum threat to BTC's elliptic-curve signatures isn't imminent, the funding signals urgency. Bitcoin's protocol relies on cryptographic primitives that fault-tolerant quantum machines could eventually compromise, making migration planning a live technical discussion rather than a distant hypothetical.

For long-term BTC holders, this development reinforces the importance of monitoring Bitcoin Core's roadmap for post-quantum signature schemes as the 2029 timeline approaches.
