AI finds Ethereum validator crash bug

Ethereum Foundation developers reportedly used AI agents to search for protocol flaws and found a remotely triggerable crash in the network’s messaging system.
The issue could have affected Ethereum validators, but it has since been fixed.
For $ETH, the key signal is that AI can help surface real security risks in complex blockchain infrastructure.
But the story also shows the limits of AI security work.
Most of the other AI findings were described as confident and well-written, but completely wrong.
Human engineers still had to separate real threats from false positives.
