Security experts warn Bitcoin faces urgent quantum risks as adversaries stockpile encrypted data
Security experts are warning that Bitcoin faces significant risks from quantum computing. Nation-state actors are currently harvesting encrypted blockchain data, anticipating that future quantum computers will be able to decrypt it. Approximately 6.9 million BTC could be at risk if quantum capabilities advance as predicted.
- ▪Experts believe that nation-state actors are employing a strategy known as 'harvest now, decrypt later' with Bitcoin's blockchain data.
- ▪Estimates suggest that between 6.5 and 6.9 million BTC have public keys visible on-chain, making them potential targets for quantum attacks.
- ▪A report indicates that Bitcoin's slower governance and upgrade timelines make it more vulnerable compared to Ethereum, which is advancing post-quantum cryptography integration.
