The problem Nomis Onchain Reputation Scorer solves

Nomis is an identity protocol and wallet-scoring infrastructure that helps developers grow their products, services and communities faster by enabling personalized web3 experiences (think cookie infrastructure for web3). Nomis enables web3-native loyalty programs, targeting campaigns, and score-based reward distribution to improve the ROI of your marketing campaigns and prevent bots from being rewarded. We make this possible by evaluating the reputation of wallets based on their on-chain activity.

As a result of the hack, we've developed Reputation Scorers for Zora and Base to help those chains' developers and web3 teams assess wallets' on-chain reputation based on their digital footprint within the Zora and Base ecosystems, respectively. In other words, Zora and Base developers can now easily answer the question 'how much does a particular wallet look like Zora/Base power users?' The Reputation Scorer enables the following super powers for BUIDLers:

• Run web3-native loyalty programs based on wallet journey data
• Create and manage bot-free communities
• Distribute rewards fairly to power users and early adopters using score-gating
• Offer custom DeFi credit terms to end-users based on their on-chain creditworthiness

We encourage Base and Zora developers to play around with Nomis Reputation Scorers on their chains and hire our API to build better and more personalized web3 products and communities!

Challenges we ran into

We hired explorer APIs and 50+ more on-chain data sources to get wallet, transaction, and NFT movement data; constructed variables, based on the data extracted which can be received via Nomis API. Finally, we hired our mathematical model to develop Nomis Reputation Scorer based on the constructed variables.
