The rapid expansion of DeFi has made people both excited and nervous. On one hand, billions of dollars in liquidity; on the other, a continuous emergence of security vulnerabilities—how can this contradiction be resolved?

Walrus Protocol offers an interesting solution. In simple terms, it focuses on excelling at two key aspects: making smart contracts more robust and implementing a sensitive "nervous system."

First, on the contract level. They adopt a modular design, with each functional block independently decoupled. The key is that these modules are not written based on intuition but are formally verified. This may sound complex, but simply put: using mathematical methods to fundamentally prove that the code does not contain logical vulnerabilities. Traditional code audits can only identify known issues, whereas formal verification can check for all potential risks. Coupled with the modular structure, upgrading individual components does not affect the entire ecosystem, significantly reducing maintenance costs.

What’s even more impressive is their real-time monitoring system. The system is distributed across multiple network nodes, continuously scanning on-chain transaction data. Machine learning algorithms play a vital role here, capable of identifying abnormal transaction patterns. Once anomalies are detected, multi-level early warnings are immediately activated, providing the security team and community with ample response time. Moreover, the entire system operates in a fully decentralized manner, eliminating the risk of single points of failure. This design approach is indeed worth other projects in the industry to reference.
