Taiko halts Layer 2 block production after bridge security breach

Taiko halts Layer 2 block production after bridge security breach

Taiko developers slammed the brakes on their mainnet today. The team took the network offline to stop block production after a security exploit targeted the bridge mechanism. It's a major blow to the Layer 2 project, which had been gaining traction as a zero-knowledge rollup.

Taiko's official channels are now telling users to pull their assets immediately to prevent further exposure. This isn't just a minor glitch; any vulnerability in proof validation strikes at the heart of rollup security. The project hasn't provided a timeline for a restart while they patch the hole.
