Over $469 Billion in Bitcoin Faces Quantum Computing Threat
- More than 30% of all Bitcoin, equating to over $469 billion, has its public key exposed on-chain.
- 6.04 million BTC, or approximately 30.2% of the issued supply, is vulnerable to quantum risk.
- Exchanges account for about 40% of operationally exposed Bitcoin, with significant variance across platforms.
- Binance and Bitfinex show high exposure rates at approximately 85% and 100%, respectively.
- The United States government plans to invest over $2 billion into quantum startups to advance industry capabilities.
Research indicates a significant portion of Bitcoin is at risk due to public key exposure on the blockchain, potentially vulnerable if quantum computing advances sufficiently. Exchange practices contribute heavily to this exposure, though it varies by platform.
Approximately one-third of all Bitcoin is currently at risk if future quantum computers can exploit known public keys, highlighting the need for improved security measures and protocol updates in the cryptocurrency space.(Source)
