BlackRock says bitcoin quantum computer risk not a major worry

BlackRock says the quantum computing threat to bitcoin and other cryptocurrency networks is technically manageable. In a report titled \"Quantum Computing and Blockchain\", it said moving existing cryptography to quantum-resistant standards is easier than building a quantum computer capable of breaking it. BlackRock said the key challenge is coordination and implementation in decentralised networks. It also flagged potential vulnerabilities in bitcoin’s current structure and announced a bitcoin security consortium with Coinbase, Fidelity Digital Assets and Block.
