Developers Propose Upgrades to Protect Bitcoin from Quantum Threats
- Google’s research indicates a quantum computer could potentially crack Bitcoin’s cryptography in under nine minutes.
- Approximately 6.5 million BTC are at risk, valued at hundreds of billions of dollars.
- Proposals like BIP 360 aim to remove public keys from blockchain transactions to enhance security against quantum attacks.
- The SPHINCS+ post-quantum signature scheme offers an alternative, though it increases signature size significantly.
- Hourglass V2 seeks to limit the sale of coins in exposed addresses to one BTC per block to prevent market collapse.
As quantum computing advances, the need for robust defenses for Bitcoin is becoming urgent, with several proposals already on the table aimed at mitigating risks associated with quantum threats.
With around 1.7 million BTC held in vulnerable addresses, developers are actively working on solutions to secure these assets against potential future attacks.
