Firstly, contract registration requests can ensure the secure storage and transmission of contracts on the blockchain, thereby improving the execution efficiency of contracts. Through blockchain technology, relevant information of contracts can be distributedly stored, preventing single-point failures while ensuring the authenticity and integrity of data. Secondly,  contract registration enables the parties involved to monitor the performance of contracts in real-time, enhancing the transparency of contract management. The data on the blockchain cannot be tampered with; once the content of a contract is recorded, all parties involved cannot modify it, thereby reducing the risk of contract disputes.
