OScore is an on-chain credit score for programmable creditworthiness which is designed based on the Orange protocol. Its workflow illustrates how an MP and a DP work together in the Orange system.
OScore can represent one's credit standing in DeFi systems. It is calculated using many different pieces of transaction data, including:
Payment history
Liquidation history
Amounts owed and repaid
Credit mix
Length of credit history
It implements a customized model and quantification of on-chain behavior and interactions with existing DeFi protocols using Orange. This ensures the scoring methodology remains empirically sound and statistically valid.
Consider the following diagram illustrating OScore's transaction data synchronization flow from Ethereum, which is the DP in this context.
An Ethereum sync node
Synchronization service that listens and monitors transactions via the sync node
Stores the relevant transaction data in a database
Stores block data for contract executor to fetch
Listens to contract events via the sync node
Logs relevant event data in a database
Stores transaction and event data
This data is stored in the database and fetched via an interface by the Orange system when the OScore model is invoked. Applications send invocation requests using an SDK. You can refer to the example here.
