Crypto researchers cut Bitcoin and Ethereum quantum attack estimate by 50%

Crypto researchers have revised their estimates for the timeline of quantum attacks on Bitcoin and Ethereum, reducing the previous projections by 50%. A paper shared with CoinDesk details how both human researchers and AI agents outperformed Google's March results on a key calculation used by Shor's algorithm, which is central to quantum factorization attacks.

This development adds a new variable to the ongoing assessment of quantum threats to blockchain security. The improved performance in solving the core calculation suggests that quantum computers could potentially threaten the cryptographic foundations of major cryptocurrencies sooner than previously expected.

The research underscores the importance of advancing quantum-resistant cryptography and preparing the blockchain ecosystem for potential future vulnerabilities. While the exact timeline remains uncertain, these findings contribute to the evolving understanding of quantum risks in the crypto space.
