Only a few months have passed in 2025, and the Layer 2 ecosystem has already been hit with over 500 million dollars in losses due to security vulnerabilities.

cmETH on Mantle was attacked, and a $12 million hook vulnerability exploded during the deployment of Uniswap V4—there's a common point behind these incidents: they all fell victim to blind trust in "fast probabilistic finality."

Speed is a good thing, but when the security foundation is not solid, attackers find an opportunity. Many L2 projects compromise on finality design in pursuit of transaction speed, resulting in these vulnerabilities being precisely exploited by hackers.

Looking at Hemi's approach from a different perspective. It directly uses Bitcoin as the settlement layer, anchoring the state to Bitcoin's proof of work through the PoP (Proof of Proof) mechanism. What does this mean? About 90 minutes later, the finality of the transaction reaches a level that attackers can hardly shake.

This is a balancing game. Some ecosystems pursue the ultimate speed experience, while Hemi chooses to prioritize security. After all, in the crypto world, lost money cannot be recovered.

Which balance will you choose?
