Therefore, Oracle is considered as the bridge between the decentralized protocol and the external data of the blockchain, and becomes an essential existence.

The Port of DeFi Network uses the Oracle assisted DeFi protocol smart contract as the data source outside the blockchain, avoiding the risks of forgery, tampering, modifying or hiding of the centralized data. It synchronously uploads the information of the world under the chain to the blockchain, and completes the information synchronization between the blockchain and the real world. …

The Port of DeFi Network returns responses through nodes to data requests or queries made to, or on behalf of, user contracts, which we call request contracts and denote with a USER-SC, and the chain interface that links the Port of DeFi Network’s request contracts is itself a chain contract as denoted by the PDF Network -SC.

Behind the PDF Network -SC, the Port of DeFi Network has an online component consisting of three main contracts: reputation contracts, order-matching contracts, and aggregation contracts. Reputation contracts track Oracle-service-provider performance metrics. …

Borrower and lender mainly refer to those parties who borrow and those that lend, hence the term borrower and lender. Decentralized lending refers to the behavior of matching the borrower and the lender through a centralized lending agreement, and then transferring the assets and completing the borrowing and lending immediately after the mortgage and pledge are confirmed. …
