Bitcoin’s Quantum Transition Won’t Stop at Bitcoin

HONG KONG, October 18, 2026 – As quantum computing advances, the challenge extends beyond Bitcoin’s cryptography to the financial infrastructure built around it. Quantum computing is emerging as one of Bitcoin’s long-term security challenges. A sufficiently powerful quantum computer could theoretically compromise the digital signatures protecting Bitcoin transactions, potentially exposing funds associated with vulnerable public keys. While no publicly demonstrated quantum computer is currently c
