Emergency drill "regular training of troops". Conduct node failure drills every month, and all participating nodes and users receive WCT rewards; teams that quickly fix vulnerabilities exposed during the drills receive additional rewards. After six months, the actual recovery time from a fault decreased from 1 hour to 10 minutes. This kind of "token-based emergency training" is much better than being flustered when incidents occur; the strength of the ecosystem is built through practice.
