How Arbitrum's Security Council Froze $70M of North Korea's Stolen Funds

Summary

Griff Green, an Arbitrum Security Council member, explains how the council used Arbitrum's forced inclusion mechanism to freeze $70 million in stolen North Korean funds. The funds were left idle for 48 hours, allowing a Layer 1 transaction to move them to a dead address without upgrading any node. The discussion also covers the role of SEAL 911, the security council's governance structure, and the launch of a quadratic funding round for Ethereum security projects.
