Bitcoin and Ethereum Accelerate Quantum Resistance Upgrades Amid $300M U.S. Quantum Investment

The U.S. Department of Commerce is allocating up to $300 million via the CHIPS Act to quantum computing firms Rigetti, D-Wave, and Quantinuum. Simultaneously, Bitcoin and Ethereum developers are fast-tracking post-quantum cryptography upgrades. The Ethereum Foundation has set a December 2029 target for base-layer quantum resistance, while Bitcoin researchers are advancing BIP-360 and BIP-361 to phase out legacy signatures by 2029.
