Bitcoin and Ethereum accelerate quantum resistance upgrades: The United States invests $300 million to bet on quantum hardware

According to CoinDesk, the U.S. Department of Commerce has allocated up to $100 million each to three quantum computing companies: Rigetti, D-Wave, and Quantinuum, totaling up to $300 million, to expand hardware, manufacturing, and error correction systems, while simultaneously acquiring minority stakes in the three companies.

Meanwhile, Bitcoin and Ethereum developers are accelerating the advancement of post-quantum cryptography upgrade plans. The Ethereum Foundation has set December 2029 as the deadline for the base layer quantum resistance upgrade, covering the execution layer, consensus layer, and data layer; although there is no unified timeline for Bitcoin, proposals BIP-360 (post-quantum output types) and BIP-361 (phasing out ECDSA and Schnorr signatures) have been accelerated, with researchers also viewing 2029 as a critical window for completing a trustworthy migration path.
