The present invention relates to a method for processing a division type factoring service for accounts receivable by using document proof using a blockchain. If an accounts receivable issuer attaches a digital signature to the blockchain through a document application server by using a distributed ID recorded in the blockchain and records the document proof, an accounts receivable receiver attaches a digital signature to the document proof of the accounts receivable issuer recorded in the blockchain through the document application server and records the same in the blockchain, so that a process of issuing and receiving electronic documents for the accounts receivables is completed with the document proof of the blockchain. If the accounts receivable receiver divides the amount of the accounts receivable to divide the same into two or more accounts receivable and sell the two or more accounts receivable, the document application server creates the hash values of the distributed ID of the electronic document of the accounts receivable, the distributed ID of an accounts receivable buyer, and the divided amount, and stores the same in tree form to divide the initial accounts receivable into several accounts receivable, and thus many people can directly trade and settle accounts receivable. The method comprises the steps in which: the document application server issues the accounts receivable by recording, in the blockchain, the document proof of the terminal of the accounts receivable issuer to which the digital signature of the accounts receivable receiver is attached. 본 발명은 블록체인을 이용한 문서증명방식의 분할방식 매출채권 팩토링서비스 처리방법에 관한 것으로, 블록체인에 기록된 분산아이디를 사용하여 매출채권발행자가 문서애플리케이션 서버를 통해 블록체인에 전자서명을 첨부하여 문서증명을 기록하면, 매출채권수취자는 문서애플리케이션 서버를 통해 블록체인에 기록된 매출채권발행자의 문서증명에 전자서명을 첨부하여 블록체인에 기록함으로써 매출채권 전자문서 발행과 수취과정이 블록체인의 문서증명으로 완료되도록 하고, 매출채권의 거래는 문서애플리케이션 서버에서 매출채권 수취자가 매출채권의 금액을 분리하여 두 개 이상의 매출채권으로 분할하여 판매할 경우 매출채권 전자문서의 분산아이디와 매출채권 구매자의 분산아이디와 분할된 금액을 해시로 만들어 트리형식으로 저장하여 최초 매출채권을 여러 개의 매출채권으로 분할함으로써 다수가 매출채권을 직접 거래하고 정산할 수 있게 만드는 방법에 관한 것이다.
