Solana co-founder urges Bitcoin community to be prepared for quantum computing threats

Solana co-founder Anatoly Yakovenko calls on the Bitcoin community to speed up its pace of preventing potential quantum attacks. He stressed that major advances in quantum computing may arrive faster than expected. At the 2025 All-In Summit, Yakovenko said the likelihood of a breakthrough in quantum technology within five years is 50%, and urged Bitcoin to move to a quantum signature resistant scheme. Yakovenko's predictions stem from the rapid integration of various technologies and the rapid development of artificial intelligence from theoretical research to practical applications. He called the acceleration shocking and encouraged the community to speed up the adoption of protective measures. Cybersecurity experts are also concerned that the threat posed by quantum computing may be implemented earlier than expected. Quantum computers are expected to eventually crack existing encryption methods, which raises security concerns among blockchain users. Still, many Bitcoin supporters believe that the threat is still out of reach. Currently, the security mechanism of Bitcoin wallets uses the elliptic curve digital signature algorithm (ECDSA), which relies on the elliptic curve discrete logarithmic problem (ECDLP) that classical computers cannot solve. However, quantum computers may be able to overcome this challenge. David Carvalho, founder and chief scientist of Naoris Protocol, warned in June that quantum computers have developed to the point where they may break through Bitcoin encryption in less than five years. Transitioning blockchain from traditional encryption to post-quantum security requires hard fork, and many crypto communities have resisted this. Despite these warnings, some Bitcoin users are not worried about the threat ahead. Blockstream CEO Adam Back said current quantum computers will not pose a credible threat to Bitcoin’s encryption technology. Although it may be realized in the future. Back estimates that quantum computers will achieve this capability in about 20 years. Similarly, Jan3 founder Samson Mow expressed minor concerns about the threat posed by quantum computing, saying that while quantum computing does have risks
