Quantum Computing Could Break Bitcoin Sooner Than You Think, Warns Coinbase Research Head

TL;DR Duong warned “Q-day” could target Bitcoin’s ECDSA signatures and SHA-256 proof-of-work, not only cold wallets. He said quantum computers could both steal funds by breaking signatures and mine blocks faster, though mining is lower priority for now and disrupt its security model overall. Duong sees today’s machines as too small to be imminent, but urges post-quantum signature migration amid debate between Adam Back and Charles Edwards as te…

Quantum Tech May Threaten Bitcoin Beyond Wallet Hacks

Quantum computing could one day weaken Bitcoin’s core security systems, which would affect both wallet safety and mining efficiency.

Coinbase Research Warns Quantum Computing Threatens Bitcoin Security

Coinbase research warns quantum computing could weaken Bitcoin’s core cryptography over the long term. About 32.7% of Bitcoin supply may be exposed due to public key reuse and legacy script types. Experts say quantum-resistant signature upgrades will be needed as computing capabilities advance. Quantum computing is emerging as a possible long-term risk to Bitcoin’s cryptographic foundations, according to research commentary from a senior analyst…

Quantum Danger to Bitcoin: More Than Just Cold Wallets Under Threat

Quantum Computing Threats to Bitcoin: Security and Mining Implications Advancements in quantum computing may pose significant risks to Bitcoin, not only compromising wallet security but also potentially disrupting its economic and security infrastructure. Experts warn that sufficiently powerful quantum computers could exploit cryptographic vulnerabilities, challenging the integrity of the world’s leading cryptocurrency. Key Takeaways Quantum co…
