Yes, a smart contract.
An initiation of the smart contract in which the next information will be specified:
- Amount of loan
- Address of creditor
- Credit interest rates
- Series of loan charges
- Unique biometric indicator of borrower
The smart contract checks whether payments are made fully and in time to the creditor. If payments are made according to stipulated conditions, the borrower's credit score is automatically raised or in the opposite case it is reduced. In case the borrower attempts to apply for new credit, they would be refused. Provided biometric data allows to unambiguously identify the person’s credit history, the reverse procedure is impossible. Credit history cannot be associated with a person due to the realization of unique biometric identifier.
