EtherScore is a reputation system that uses NFTs to represent Web3 achievements. The system provides badges based on user interactions such as voting in DAOs, swapping or lending coins/NFTs, etc. Users can collect badges to improve their on-chain reputation and build their EtherScore profile. On top of this, Dapps can develop services that require a reputation system, such as curated social networks, fair airdrops/ICOs, DeFi, DAO governance etc. Chainlink and The Graph are used for decentralization and verifiability of our solution.
The alpha version of EtherScore is live on Mumbai testnet and offers more than 80 badges for users of the most popular Dapps and chains. Of these 80 badges, 13 are related to the Optimism ecosystem, cumulating to 120,000 mints (details in the Impact section).
