Blockchain-integrated decentralized fault tolerance for secure and energy-efficient multi-cloud interoperability

Cloud service provider, multi-cloud scheme has become a strategic fashion to maximize reliability, affordability, and performance. To pose major difficulties with regard to fault tolerance, interoperability, security, and muscularity economy. To address these issues, this employment suggests a unique blockchain-integrated decentralized error allowance system. The advice model uses Proof of Stake (PoS) as the consensus chemical mechanism to improve DOE economy while preserving strong security measure and performance criteria. By around 30 %, smart contracts help to automatically reclaim defect, therefore greatly let down migration costs and downtime. To guarantee data integrity and secrecy across heterogenous swarm environs, the model as well flux a multi-layered security computer architecture desegregate homomorphic encryption, Zero-Knowledge Proofs (ZKP), and Decentralized Identity (DIDs). Atomic swop and cross-chain bridgework avail to enable cross-chain interoperability, hence enabling flawless and good data point exchanges with lower limit delay. Validating the achiever of the indicate strategy, the data-based finding point important addition in free energy efficiency, certificate success rate outdo 90 %, and lour migration costs. These results show the hypothesis of the suggested model to change multi-cloud direction strategies, thereby offering a strong ground for future investigations and practical applications.
