Bitcoin, ethereum diverge on quantum computing response strategies

As quantum computing emerges as a long-term security challenge for blockchain, bitcoin and ethereum are taking different approaches. Bitcoin is leaning toward gradual steps that preserve its existing structure, including proposals such as BIP-360 to reduce public key exposure. Ethereum is outlining a structured roadmap that treats quantum resistance as a multi-layer system upgrade, emphasising cryptographic agility. Both networks have yet to finalise solutions, and near-term market impact is seen as limited.

Toshiba says quantum-inspired computing algorithm boosts speed 100-fold

Toshiba has unveiled a quantum-inspired computing algorithm that simulates quantum calculations on classical computers, saying it improves speed and accuracy at the same time. The company said the algorithm can run up to 100 times faster than existing methods and achieve near-100 percent accuracy by using the “edge of chaos” concept. It cited a case where runtime fell from about 1.3 seconds to under 0.01 seconds.

Musk says even lost BTC wallets will one day open as Google reignites quantum debate

Elon Musk (일론 머스크) joined a renewed debate over whether quantum computers could crack Bitcoin encryption, saying even wallets with forgotten passwords may become accessible one day. The discussion resurfaced after summaries of Google research spread again on social media, including a post claiming Google cut required resources by 20 times. Google set 2029 as a target to complete a shift to post-quantum cryptography, and a paper suggested ECC-256 could be broken with under 500,000 physical qubits.
