# Composable Reputation *Learnings from Repgrind: The Web3 Reputation System Builder* By [nintynick.eth ๐Ÿงข](https://paragraph.com/@nicknaraghi) ยท 2022-03-18 highlight --- Over the last few months, I hacked on a reputation project with David Ehrlichman and Marco Spilimbergo. Here's what we attempted and learned. The basic premise was this: reputation systems are fundamental to how humans operate, but they are implicit and therefore centralized. Building a decentralized reputation system is hard. So we were working on a way to create, discover, and apply composable reputation systems. It consisted of a no-code reputation system builder and a marketplace for finding reputation building blocks from other people.

The onchain data is there. In order to build meaningful reputation systems, it has to be perspectival (aka context-specific). So making it really easy to build lots of systems for reading the data and mixing and matching them seems like the way to do it. Later, David and I worked on building out a project called the DKD (DragonKillDAO, based on DragonKillPoints) to try to create the perfect base mechanism that would naturally evolve into context-specific reputation systems. The prototype was in Discord using currency tracking by MEE6 bot, which was a pretty good place to start.

I often refer back to this quote from Joi Ito on Toshio Yamagishi's work in particular: ![](https://storage.googleapis.com/papyrus_images/35a5c91cea3cb46eb12a363d71f32189.jpg) * * * _May 2024 update:_ If you're going to build a decentralized reputation system, you almost certainly need to use a recursive mechanism like PageRank. Spencer Graham wrote about what we're seeking for the Hats Protocol ecosystem [here](https://docs.google.com/document/d/1kGrvXO-J6XNRl0S8ryVDI9d--8xsDKNCyWkFw8wREc4/edit#heading=h.3omr0z1lrrha). The DKD Game Rules link above is very congruent with tipping in $DEGEN, (and $enjoy and $RARE). I think this is going to evolve into a stable and foundational primitive in crypto pretty soon. I might work on an ERC-20 fork just for tipping. The whole point of crypto is programmable value! This design space is severely under explored. Keep trying to program the representations of value in new ways! --- *Originally published on [nintynick.eth ๐Ÿงข](https://paragraph.com/@nicknaraghi/repgrind-composable-reputation-1)*
