Supply Chain Finance in Blockchain-based Digital Asset Platform

Assets such as warehouse receipts and pre-sale certificates are important for enterprises,which can be used to pledge in supply chain finance. In China, traditional supply chain finance is done manually by the bank side, which inevitably encounters problems such as multiple pledges and unclear rights on assets. In this paper, we propose a blockchain-based digital asset platform (DAP), which not only embeds digital signatures and smart contracts to improve the reliability of supply chain finance between enterprises and banks but also the data stored on the DAP blockchain makes traceability possible. Besides, DAP is built on DNA-based Consortium blockchain and threshold ECDSA Algorithm, which is autonomous and controllable. Moreover, subsequent performance tests show that DAP has a high ability to process transactions and has a greater potential for application.
