To ensure a blockchain network operates healthily, node reputation assessment is actually quite crucial.

Imagine a system that can track each node's response speed, data completeness, and online stability, then score them based on these historical performances. Such a scoring system can directly influence how rewards are distributed and how data tasks are assigned. Nodes that perform well naturally get more opportunities.

But there's a problem to watch out for— the Matthew effect, where the strong get stronger and the weak are marginalized. Therefore, when designing this mechanism, it's important to find ways to maintain the network's openness, so that new nodes or small and medium nodes still have opportunities to stand out. Balancing these aspects is key to building a network ecosystem that is both quality-assured and vibrant.
