8 stories about Quantum Computing from across the crypto press, curated and summarized daily. Most recent: Nov 1, 2026.
Nasdaq-listed Next Technology Holding has authorized selling or borrowing against its 5,833 bitcoin, valued in the headline at about $450 million. The company cited exchange-security and quantum-computing concerns, while saying none of its bitcoin is held at Binance.
Google says its Willow quantum chip can prepare certain states needed for advanced calculations with about 40 times fewer errors, improving one part of the hardware needed for a future attack on Bitcoin wallets. The report does not mean current Bitcoin wallets have been cracked: a capable, large-scale quantum computer remains a future concern.
Nine crypto companies have launched the Quantum Alliance to coordinate preparation for possible quantum attacks on blockchain security. The group agrees the risk deserves attention, but not on when it may arrive or whether vulnerable bitcoin should be frozen; a Google research advance adds to the debate without setting a clear countdown.
Bitcoin Magazine reports researchers built a working post-quantum defense for Lightning, but the report lacks design details or performance data. Separately, Coinbase urges Bitcoin to adopt flexible addresses and backup quantum-proof keys now.
Ethereum has finalized the Frame Transactions feature in the Hegotá upgrade, allowing users to pay gas fees without holding ETH. This move, supported by Vitalik Buterin, aims to enhance flexibility and security, including protection against quantum computing threats.
Ripple is updating the XRP Ledger to protect against quantum computing attacks, following recent advancements in quantum cryptography. Bitcoin and Ethereum have also announced plans to migrate to quantum-resistant technology. The industry is racing to prepare for 'Q-Day,' the point at which quantum computers can break current encryption.
StarkWare successfully executed the first Bitcoin transaction resistant to quantum computing threats. However, they warn that Bitcoin still needs a protocol-level upgrade for full protection.
Coinbase is building a post-quantum custody system and funding Bitcoin's cryptographic upgrades to protect against future quantum computing threats. While the threat is not imminent, quantum computers could one day break Bitcoin's cryptography.
