Implementation of a Blockchain-Based Secure Cloud Computing Mechanism for Transactions

Abstract

Abstract The distributed ledger known as blockchain is designed to record transactions in a manner that makes hacking, tampering, and fraud very difficult, if not impossible. Blockchains are digital distributed ledgers that keep track of transactions across several computers. The blockchain is a revolutionary financial innovation that will change the face of commercial transactions forever. This decentralized system employs and supports a wide variety of encryption methods. Due to the cloud computing paradigm, financial transactions are safe, reliable, and adaptable. This chapter provides a secure method for implementing cloud assurance using blockchain technology. The blockchain transactions are first recorded using the SHA-256 cryptographic method. After that point, the characteristics of blocks are stored, and the transactions are serialized. Finally, the blockchain would produce new blocks if certain transaction and condition criteria were satisfied. Each step of the transaction is monitored using a Merkle tree to guarantee its security and authenticity. The research did, however, highlight several major gaps in the available literature and the implications of those gaps.
