Summary:The present invention relates to a transaction method of a change encryption transaction system using a blockchain, comprising: a digitization step of determining a change less than a predetermined amount, which is remained as a transaction in a POS device when a customer performs cash transaction with a business owner, as digital currency data; an encryption step of allowing the POS device to request a virtual currency transaction server to encrypt the digital currency data for the change in a blockchain method to acquire encrypted digital currency data; a transmission step of allowing the POS device to transmit the encrypted digital currency data to an application of the customer′s smart device; and a storage step of allowing the application of the customer′s smart device to store the encrypted digital currency data. Accordingly, when the customer buys a product with cash in various member stores, the change is encrypted into the digital currency data by application of blockchain technology, thereby being simply stored in the application of the customer′s smart device and the like, using again a stored deposit, and allowing the POS device of the member store and the application having an encryption function embedded therein to link data with each other through a barcode or an RFID mode. 본 발명은 소비자가 사업자에게 현금 거래시 포스기에서 거래로 남게되는 일정금액 미만의 잔돈을 디지털 화폐 데이터로써 판단하는 디지털화단계; 포스기가 가상화폐 거래서버에 요청하여 블록체인 방식을 통해 잔돈에 대한 디지털 화폐 데이터를 암호화하여 암호화된 디지털 화폐 데이터를 얻는 암호화단계; 포스기가 암호화된 디지털 화폐 데이터를 소비자의 스마트기기의 앱에 전송하는 전송단계; 소비자의 스마트기기의 앱에서 암호화된 디지털 화폐 데이터를 저장하는 저장단계; 로 이루어지는 것으로, 본 발명 블록체인을 이용한 잔돈 암호화 거래시스템의 거래방법은 다양한 가맹점에서 소비자가 현금으로 상품을 구매하고 잔돈을 디지털 화폐 데이터로써 블록체인 기술을 적용하여 암호화한 후, 소비자의 스마트폰 등의 앱에 간편히 저장하고, 저장된 적립금은 다시 재사용할 수 있고, 가맹점에 있는 포스기와 암호화 기능이 내장된 앱은 바코드 또는 RFID 방식을 적용하여 데이터를 연동하는 현저한 효과가 있다.
