Solana co-founder Anatoly Yakovenko has issued a warning that Bitcoin must upgrade to a quantum-resistant signature scheme by 2030 to prevent potential security breaches from advances in quantum computing. Yakovenko suggests there is a 50% chance that quantum computers could be capable of breaking Bitcoin's private keys within the next five years. Implementing such an upgrade would require a hard fork and broad consensus within the Bitcoin community. However, industry figures such as Blockstream CEO Adam Back and Bitcoin core developer Peter Todd have expressed skepticism about the immediacy of the quantum threat, suggesting it is not a realistic concern in the short term.
