A Secure Data Controller System Based on IPFS and Blockchain

초록

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.
