Quantum Computing Threatens Bitcoin Security: The Need for Post-Quantum Solutions

Roman Oleynikov has claimed that a quantum computer might 'awaken' Satoshi's 'sleeping' bitcoins. In the era of quantum technologies, blockchain security issues are becoming particularly important. Currently, quantum machines lack enough qubits to attack major cryptocurrencies; however, preparing post-quantum algorithms is crucial—this allows systems to be swiftly secured against future threats. Old Bitcoin addresses with exposed keys are especially vulnerable because they are not protected by modern encryption. Contemporary addresses already employ hashed keys, making quantum attacks more difficult. Overall, Proof-of-Stake mechanisms are more adaptable for future updates. The expert believes that breakthroughs could be achieved through zero-knowledge proofs—ZK—which will enable the scaling of blockchains, complex computations, and AI model training, thereby increasing the efficiency and security of distributed systems 🚀.
