TL;DR
- Changpeng Zhao warned that artificial intelligence could facilitate attacks against Bitcoin users without needing to break its cryptography.
- Vitalik Buterin also expressed confidence in current cryptographic security, although other researchers have warned that advances in AI could compromise digital signatures.
- Bitcoin Core has revised its vulnerability disclosure policy to release fixes more quickly when security flaws can be easily discovered using AI.
Changpeng Zhao (CZ), founder of Binance, warned that artificial intelligence could pose a threat to Bitcoin users even without breaking its cryptography. He pointed to phishing and social engineering attacks as more immediate threats than a potential compromise of cryptographic algorithms.
Zhao believes Bitcoin’s cryptographic mechanisms remain resilient and that AI could exploit leaked information to deceive users and gain access to their assets.
Ethereum co-founder Vitalik Buterin also expressed confidence in the security of current cryptographic systems. However, there is considerable disagreement within the industry over whether artificial intelligence could discover previously unknown mathematical weaknesses.
Everyone worried about AI hacking crypto, but the internet and banking systems rely on weaker encryption.
That said, AI doesn’t need to break Bitcoin’s cryptography to cause damage, leaked data already enables more phishing, social engineering, etc,
Stay SAFU!

Debate Over the Cryptographic Risks of AI
Ethereum Foundation researcher Justin Drake warned that an AI-discovered mathematical breakthrough could compromise the ECDSA digital signature algorithm, which is used to verify the authenticity of transactions.
Drake suggested that such a vulnerability could allow attackers to recover private keys and severely undermine cryptocurrency security.
His comments drew strong criticism from Yehuda Lindell, Coinbase’s head of cryptography, and Adam Back, CEO of Blockstream, who questioned the likelihood of that scenario.
Matthew Green, a cryptographer at Johns Hopkins University, argued that the possibility of machines finding mathematical solutions that human researchers have overlooked should not be dismissed entirely.
Bitcoin Core Accelerates the Release of Security Fixes
Bitcoin Core announced changes to its vulnerability disclosure policy because artificial intelligence models can now identify certain software flaws with relative ease.
Developer Antoine Poinsot explained that keeping easily discoverable vulnerabilities secret can delay the release of fixes without providing meaningful protection.
Under the new rules, vulnerabilities classified as easily discoverable will receive fixes across all maintained versions, accompanied by a security advisory.
For other vulnerabilities, disclosure timelines will continue to depend on severity. Low-severity issues will be disclosed two weeks after a major release containing the fix, while medium- and high-severity vulnerabilities may remain undisclosed until support ends for the last affected version.
The revision addresses risks already affecting software development. In August, a Bitcoin security research team identified nearly 5,000 potential issues across more than 390 projects using AI-assisted tools, including hundreds of vulnerabilities classified as high or critical severity.
