Recently studying the architectural design of the Walrus protocol, I discovered a very critical issue—how does the system hold up when large-scale node failures or network partitions occur?

This brings us back to disaster recovery and network resilience. The protocol layer must have predefined response plans and cannot rely on last-minute solutions. More importantly, resilience testing should be conducted regularly to simulate various extreme scenarios and see if data can truly be recovered.

There are two core metrics that are especially important in measuring system resilience—Recovery Time Objective (RTO) and Data Recovery Point Objective (RPO). These two indicators need to be clearly designed, and the test results should be made open and transparent. Only then can we truly verify whether a protocol can stand the test.
