Blockchain Based Model for Cloud Computing Security

Abstract: Blockchain technology is a data structure used to create a distributed ledger along with report of information holding the entire particulars (like a hash of the previous block, timestamp means when the block was created, block reward, block number etc.) of the dealings accomplished as well as disseminated between the nodes existing in the association. Total dealings accomplished in the arrangement are established by the protocols of consensus which used to keep the blockchain secure like Proof-of-work, proof-of-stake etc., and the records once put in storage cannot be changed. Bitcoin is a most fashionable electronic Cryptocurrency uses Blockchain technology. In the environment of cloud is an on demand availability of computer resources and live out of using a system of faraway servers accommodated on the net to data storage, data control, and processing information, more willingly than a private computer or native server. Authenticity, confidentiality and integrity are the major challenges still having in the cloud environment.  In this research work, we have revealed more or less of the important challenges handled through the cloud moreover projected great solutions by assimilating it through technology of Blockchain.  Keywords: Blockchain technology, Cloud computing, Security, Blockchain Cloud, Decentralized.
