“…Additionally, by leveraging cryptography, a fundamental aspect of blockchain technology, EOSIO en-sures irrefutability across all network transactions. The implementation of SCs plays a vital role in achieving this desired behavior [22]. SCs are self-executing scripts that re-side on the blockchain enabling the establishment of e cient, decentralized and highly automated work ows [23].…”

Recent research has focused on applying blockchain technology to solve security-related problems in Internet of Things (IoT) networks. However, the inherent scalability issues of blockchain technology become apparent in the presence of a vast number of IoT devices and the substantial data generated by these networks. Therefore, in this paper, we use a lightweight consensus algorithm to cater to these problems. We propose a scalable blockchain-based framework for managing IoT data, catering to a large number of devices. This framework utilizes the Delegated Proof of Stake (DPoS) consensus algorithm to ensure enhanced performance and efficiency in resource-constrained IoT networks. DPoS being a lightweight consensus algorithm leverages a selected number of elected delegates to validate and confirm transactions, thus mitigating the performance and efficiency degradation in the blockchain-based IoT networks. In this paper, we implemented an Interplanetary File System (IPFS) for distributed storage, and Docker to evaluate the network’s performance in terms of throughput, latency, and resource utilization. We divided our analysis into four parts: Latency, throughput, resource utilization, and file upload time and speed in distributed storage evaluation. Our empirical findings demonstrate that our framework exhibits low latency, measuring less than 0.976 milliseconds. The proposed technique outperforms Proof of Stake (PoS), representing a state-of-the-art consensus technique. We also demonstrate that the proposed approach is useful in IoT applications where low latency or resource efficiency is required.

Access control or authorization is referred to as the confinement of specific actions of an entity, thereby allowing them to be performed as per certain rules. Blockchain-driven access control mechanisms gained considerable attention directly after applications beyond the premise of cryptocurrency were found. However, there are no systematic efforts to analyze existing empirical evidence. To this end, we aim to synthesize litera- ture to understand the state-of-the-art blockchain driven access control mechanisms with respect to underlying platforms, utilized blockchain properties, nature of the mod- els and associated testbeds and tools. We conducted the review in a systematic way. Meta analysis and thematic synthesis were performed on the findings from relevant primary studies, in order to answer the framed research questions in perspective. We identified 76 relevant primary studies that passed the quality assessment. The problems targeted by relevant studies were single point of failure, security, and privacy, etc. The meta-analysis of the primary studies suggests the use of different blockchain platforms along with several application domains where different blockchain proprieties were utilized. In this paper, we present a systematic literature review of blockchain driven access control systems. In hindsight, we present a taxonomy of blockchain-driven access control systems to better understand the immense implications of this field spanning various application domains

“…Differently than the already existing blockchain-based frameworks in the literature [26]- [28], EdgeMediChain leverages the edge computing paradigm to ensure availability and parallelized high performance, precisely, in terms of handling the astonishing amount of monitored data generated from the IoT devices and body sensors, meanwhile, the blockchain technology was adopted to provide the required privacy and security in the process of sharing health data. We extend our work in [29], by introducing a new source of data (i.e., IoT body sensors) and focusing on the main idea of integrating a set of local consortium blockchains, namely local edge-mining pools, to manage the IoT devices' accounts, authentication, and data storage (i.e., the behavior of the IoT devices). Smart contracts are also utilized to ensure an automated regulation vis-à-vis AC rules and policies governing the access to the shared health data in a decentralized and non-deniable way.…”

Recently, researchers around the world in medical institutions and pharmaceutical companies are demanding a wider access to healthcare data for secondary use in order to provide enhanced and personalized medical services. For this purpose, healthcare information exchange between health authorities can be leveraged as a fundamental concept to meet these demands and enable the discovery of new insights and cures. However, health data are highly sensitive and private information that requires strong authentication and authorization procedures to manage the access to them. In this regard, the cloud paradigm has been used in these e-healthcare solutions, but they remain inefficient due to their inability to adapt to the expanding volume of data generated from body sensors and their vulnerability against cyberattacks. Hence, collaborative and distributed data governance supported by edge computing and blockchain promises enormous potentials in improving the performance and security of the whole system. In this paper, we present a secure and efficient data management framework, named "EdgeMediChain", for sharing health data. The proposed architecture leverages both edge computing and blockchain to facilitate and provide the necessary requirements for a healthcare ecosystem in terms of scalability, security, as well as privacy. The Ethereum-based testbed evaluations show the effectiveness of EdgeMediChain in terms of execution time with a reduction of nearly 84.75% for 2000 concurrent transactions, higher throughput compared to a traditional blockchain, and scalable ledger storage with a linear growth rate.
