When I first encountered @ethos_network , an on-chain reputation system, the first thing that came to mind was the potential of an on-chain game profile. And finally, @Ronin_Network has brought that vision to life. Since the launch of @MaplestoryU , the biggest complaints from players have been about cheaters and scammers. But what kind of future can we imagine if a game profile is tied to a wallet? From the perspective of game projects, it becomes much easier to identify and select trustworthy players. Over time, malicious users will gradually disappear from the ecosystem. Players with good reputations will receive greater rewards and benefits, while cheaters and scammers will earn only minimal rewards. This mechanism, combined with the incentive structure of blockchain, works especially well and significantly enhances the health and sustainability of the gaming ecosystem. An on-chain reputation system has the potential to become the new standard for blockchain games.
