B-FEF-blockchain based framework to exchange files

Blockchain-based systems have proven to be efficient and capable of resolving the majority of security issues relating to exchange transactions in the system. As a result, it became necessary to move away from the problems of the existence of third parties in the system with an important level of trust; a decentralized method of transferring digital files was created. In this paper we present B-FEF-Blockchain Based Framework to Exchange Files. This solution uses IPFS and the Ethereum blockchain. The suggested method offers irreversible and irreversible records of the transmission and reception of documents. In the work system, it is available to all participants who have successfully registered and depending on the smart contract offered by Ethereum blockchain to start sending and receiving documents according to available applications or needs. In the end, the results of the B-FEF model showed that a single transaction costs about 0.387020062 Ether, that is, it showed a positive side in terms of the total cost rate. Also, in comparison with the methods previously presented in five of the previous researches and based on assessments based on eight basic criteria, the analyses supported our claim that the proposed model fulfills all these criteria. As for the basic trio of confidentiality, integrity and availability analysis, the proposed model proved to meet these fundamentals.
