I have been working on the high level concepts for a marketplace protocol that will be built on Ethereum. To that end I have been exploring implementations of reputation systems and have seen a few common recurring themes.
- Systems that mimic traditional data scoring systems like Ebay albeit with the data being stored in a decentralized and immutable manner
- Systems that utilize the protocols token as collateral for staking in order to deter / punish bad actors (eg Numerai)
- Systems that use tokens that are separate from the protocols main token that serve only as a measure of reputation and which cannot be bought or sold (eg Swarm City)
I am interesting in knowing if there are any other 'superior' approaches to reputation on the blockchain that I should explore?
