What makes building reputation systems so tricky in Web3? It's one of those problems that sounds simple on the surface—track behavior, reward reliability, punish bad actors—but explodes in complexity the moment you dig deeper. You've got trust bootstrapping issues, Sybil attack vectors, collusion risks, and the fundamental challenge of creating systems that actually reflect real merit rather than just gaming mechanics. How do you design something that's resistant to manipulation while staying decentralized? These design tensions are exactly what make reputation architecture in blockchain ecosystems such a fascinating puzzle.
