摘要

Blockchain technology functions as an innovative solution that allows users to obtain secure decentralized tamper-resistant data management capabilities. The traditional blockchain systems demonstrate drawbacks because they create scalability challenges and need high amounts of energy for operations together with delayed transaction times, especially when used in high-throughput and resource-constrained situations. This research designs an improved cloud-based blockchain system which combines Proof-of-Stake (PoS) protocol with Byzantine Fault Tolerance (BFT) controls, along with batch transaction handling systems, to foster better performance results. The framework delivers dynamic scalability and distributed processing efficiency because it makes use of cloud infrastructure. The implementation simulation reveals substantial increases in transaction rate upto 10,000 TPS and quicker consensus times together with enhanced validator impartialty as well as more than 60% energy efficiency improvement, as compared to standard Proof-of-Work protocols. Security and trust evaluation methods exhibit thorough testing of the system that confirms its capabilities in adverse environments. This proposed framework provides an energy-efficient solution which can serve robust real-world applications in IoT together with healthcare and supply chain and finance domains.
