Bitcoin Quantum Threat: Developers Issue Warning At ETH Denver, developers warned that quantum computing could threaten Bitcoin's signature security, with around 30% of Bitcoin exposed to public keys. Developers are focusing on signature security rather than the SHA-256 algorithm. As the threshold for quantum hardware lowers, Bitcoin and Ethereum developers are ramping up quantum planning. Hunter Beast stated that the concern lies with signatures rather than hash algorithms, as Shor's algorithm can reverse-engineer private keys. In 2024, Google's breakthrough quantum chip is expected to advance the technology further. Alex Pruden pointed out that signature security is particularly sensitive to quantum computing threats. Over 6.9 million Bitcoins face long-term exposure risks. Additionally, the proposal to freeze Satoshi's Bitcoins is considered complex and challenging. If quantum computing takes the lead, 4 million Bitcoins flooding the market could destroy the project. (decrypt)
