An enhanced consortium blockchain diversity mining technique for IoT metadata aggregation

Over the last two decades, Internet of Things (IoT) networks have grown exponentially. Although the devices have relatively low memory, resource, and processing capability, the trend is that nodes generate a large volume of data. That is where cloud technology comes into play to provide storage space. Because of its centralized nature and robustness, a large network operating with cloud assistance may be vulnerable. Due to rigid access control policies, the devices may be vulnerable to malicious activity. On the other hand, cloud technology provides a platform for such a security system to operate. A centralized secure architecture fails to consider mobile and edge devices within the context of these criteria. This raises numerous concerns about trusting third-party cloud intermediaries, which cause security and privacy leaks. The goal of this research is to look into the problem of blockchain consensus algorithms and their applicability in IoT with cloud-native infrastructure in the Ethereum and MultiChain variants. The significant challenge is scaling the core layer without sacrificing decentralization, security, or public verifiability. This type of testbed is used to investigate the impact of architectural design and consensus models in a lightweight IoT environment. Consensus in each IoT transaction remains the most important aspect of blockchain-enabled IoT networks. When the ledger is updated without privacy protection, transaction-oriented breaches can occur. Current practices for integrating finite IoT network resources into infrastructure-oriented blockchain implementations are flawed due to they are willing to sacrifice data security and integrity in order to save time and energy. This encourages researchers to investigate an improved lightweight block verification approach to the blockchain functional framework, that decreases processing needs, network latency, and network overhead substantially. As a result, the layer-3 consensus promotes blockchain to include the block with a 35% improvement in base layer block time efficiency and a 56% increase in throughput.
