New research shows that quantum computers with about 1,200–1,450 logical qubits could break major blockchain cryptography like Bitcoin and Ethereum's secp256k1 within minutes. This highlights risks such as "on-spend" attacks during transaction confirmation and vulnerabilities in dormant wallets. Ethereum has launched a multi-year plan to transition to quantum-resistant cryptography, but the process is complex due to network coordination and user wallet migrations. While the threat is not immediate, early preparation is crucial to secure blockchain networks against future quantum attacks.
