Early Bitcoin Addresses Exposed to Quantum Attack Risk
The Bitcoin community is facing a potential threat from future quantum attacks due to the exposure of public keys in early addresses. Researchers warn that Satoshi Nakamoto's early Bitcoin could be prime targets for such an attack, as many of these units are held in exposed addresses.
According to security researcher Justin Drake, this vulnerability does not require panic since coins behind hashed addresses can remain protected until they are spent. However, the issue highlights a challenge for crypto security and protocol upgrades.
The development raises concerns for Bitcoin wallet practices, quantum preparedness, and broader crypto adoption. The market capitalization of Bitcoin stands at $3.00T, with a 24-hour spot volume of $57.30B and an ETH gas fee of 0.16 Gwei as of September 21, 2026.
