Solana co-founder warns: Quantum Computing threatens Bitcoin security, developers need to prepare in advance.

Anatoly Yakovenko, co-founder of Solana, warned that Bitcoin developers must prepare for potential breakthroughs in quantum computing, as this could render the network's existing security measures obsolete. He believes there is a "50%" chance that Quantum Computers will break Bitcoin's encryption defenses within the next five years. Shor's algorithm can crack the elliptic curve digital signature algorithm (ECDSA) that protects Bitcoin's Private Key, and once this technology matures, it will pose an existential threat to the network.

Quantum Threats: Future Challenges to Bitcoin Security

At the 2025 All-In Summit, Solana co-founder Anatoly Yakovenko reignited the debate over the long-term security of Bitcoin. He stated that there is a "50 percent" chance that Quantum Computers will become powerful enough within the next five years to break the encryption security measures protecting Bitcoin wallets.

This concern mainly focuses on the Shor Algorithm, which can derive the private key from the public key in polynomial time. This poses a significant risk for networks like Bitcoin that protect private keys and verify transactions based on the ECDSA algorithm. Once this algorithm is effectively utilized, attackers will be able to forge transactions and control wallets, posing an existential threat to the entire network. Yakovenko believes that Bitcoin should migrate to quantum-resistant signature schemes before quantum-safe technologies mature.

Controversy Focus: Urgency and Adaptability

However, there are still disagreements within the Bitcoin community regarding the urgency of the quantum threat. Blockstream CEO Adam Back believes that this technology is still relatively distant and claims that making Bitcoin "quantum ready" is quite simple. Bitcoin core contributor Peter Todd, however, disagrees, stating that current quantum computers do not exist and that "those demonstrations running toy-level problems do not count." Another core contributor, Luke Dashjr, believes that compared to issues like spam transactions and developer corruption that the community currently faces, the urgency of the quantum threat is lower.

The design of Bitcoin makes any quantum upgrade complicated. The migration to post-quantum cryptography (PQC) requires a hard fork, which is a highly controversial and technically complex process that needs broad support from the entire network. Yakovenko counters these skeptics by pointing out the rapid advancements in AI technology, arguing that this demonstrates how quickly laboratory research can translate into real-world applications. He suggests that when tech giants like Apple or Google deploy quantum-safe encryption stacks, "it is time for Bitcoin to migrate its security infrastructure."

Conclusion

The discussion about quantum threats highlights the ongoing interaction between technological advancements and cryptographic security. Although the specific timing of the threat remains contentious, the necessity of long-term solutions is undeniable. For the Bitcoin community, the core challenge lies in how to effectively fend off powerful threats that may arise in the future through technological upgrades while adhering to core principles such as decentralization and immutability, ensuring its long-term security as the cornerstone of global digital assets.
