A Secure Data Controller System Based on IPFS and Blockchain

Abstract

Blockchain is mainly used to store the amount of coins transferred and the information of sender/recipient in text format. Treating such simple information, computing and comparing hashes of the blocks, and maintaining its integrety already burden the system, which causes ‘the limit of block capacity’, the difficulty of putting a large amount of data in one block of the blockchain. This presents a solution to the block capacity problem by efficiently distributing and encrypting files using the IPFS program with which a large amount of data is recorded outside the Blockchain.
