Solana co-founder Anatoly Yakovenko has issued a serious warning about Bitcoin’s future security. He believes there’s a 50/50 chance that quantum computers could break Bitcoin’s current encryption by the year 2030. If that happens, billions of dollars in Bitcoin could be at risk.

Yakovenko is urging the Bitcoin community to act fast and upgrade the network to use quantum-resistant cryptography. He made this statement at the All-In Summit 2025, emphasizing how quickly technology, especially artificial intelligence and quantum computing, is evolving.

Right now, Bitcoin relies on a system called ECDSA (Elliptic Curve Digital Signature Algorithm) to keep wallets safe. This method uses complex math problems that are very hard for normal computers to solve. But quantum computers work differently and could easily break this encryption using a method known as the Shor algorithm.

If a powerful quantum computer is built, it could expose private keys from Bitcoin wallets that have already revealed their public keys. This would allow hackers to steal funds directly from those wallets.

David Carvalho from Naoris Protocol agrees with Yakovenko, saying the threat from quantum computers could become real in just five years—not decades away, as some believe. He warns that this is no longer a distant problem but an immediate concern.

Yakovenko also notes that upgrading Bitcoin’s system won’t be easy. It might require a hard fork, which means every user would need to update their software—a massive and complicated task. But waiting too long to act could be dangerous.

While some in the crypto space think the threat of quantum computing is still far off, Yakovenko argues that the chance of a breakthrough is high enough that action needs to be taken now.

Other experts in the crypto industry, including Ethereum co-founder Vitalik Buterin, have echoed similar concerns about quantum attacks on digital currencies.

The bottom line: To protect Bitcoin’s future, developers need to start moving toward quantum-resistant security. The technology is evolving fast, and if Bitcoin doesn’t adapt, it risks falling behind.
