Tanuki is a trustless wallet scoring protocol. It uses ZKP’s to trustlessly read historical on-chain activity to calculate wallet scores. Wallet scores are modular, enabling use cases like paymasters with loyalty-based subsidies and lending protocols with variable rates.
- Reputation scores, e.g. on-chain PageRank
- Credit score protocols which offer different terms to users based on their scores
- NFT pricing models that consider the wallets' past interactions with the NFT to accurately estimate price.
- Paymasters that determine the amount of gas fee reimbursement for each user. Currently, these methods are performed off-chain, resulting in centralized, less transparent, and trust-dependent systems.
- Spam prevention on Lens: create a social credit score for accounts, only allow posting / interaction based on certain minimum score
