SAFE E-COMMERCE SYSTEM IMPLEMENTED BY SEPARATING AND STORING INFORMATION ON SHARED AND DISTRIBUTED LEDGER AND EXTERNAL STORAGE DEVICE ON BLOCK CHAIN

摘要

The present invention relates to an online e-commerce system and, more specifically, to a method for enabling safe e-commerce by interfacing with a distributed ledger managed by a block chain technique and a distributed storage for managing various content required for electronic transaction. Specifically, when storing data, information that requires high security such as transaction history and is to be shared with other nodes is stored in a block chain and called on-chain data. Big data such as proposals or product descriptions is stored outside the block chain, and called off-chain data. The object of the present invention is to separate and process data of different purposes and enable safe e-commerce in a block chain network.;COPYRIGHT KIPO 2019
