“…Complying with legal requirements: there is some controversy on the topic of the suitability of blockchains to address the general data protection regulations (Voigt and Bussche, 2018). Restructuring views to comply with the personal data privacy requirements in a permissioned setting (maintaining proofs or links to the original views) could be a solution to this problem (Manevich et al, 2021;Montgomery et al, 2020).…”

PurposeThe complexity of business environments often causes organizations to produce several inconsistent views of the same business process (BP), leading to fragmentation. BP view integration attempts to produce an integrated view from different views of the same model, facilitating the management of BP models.Design/methodology/approachTo study the trends of BP view integration, the authors conduct an extensive and systematic literature review to summarize findings since the 1970s. With a starting corpus of 918 documents, this survey draws up a systematic inventory of solutions used in academia and industry. By narrowing it down to 71 articles, the authors discuss in-depth 17 BP integration techniques papers, classifying each solution according to 9 criteria.FindingsThe authors' study shows that most view-integration methods (11) utilize annotation-based matching, based on formal merging rules. While most solutions are formalized, only approximately half are validated with a real-world use case scenario. View integration can be applied to areas other than database schema integration and BP view integration.Practical implicationsBy summarizing existing knowledge up to June 2021, the authors explore possible future research directions. The authors highlight the application of view integration to the blockchain research area, where stakeholders can have different views on the same blockchain. The authors expect that this study contributes to interdisciplinary research across view integration, namely to the context of blockchain.Originality/valueThis survey serves to pave the way for future trends, where the authors highlight the application of view integration to blockchain research.

“…The transaction flow has three steps: i) execution, verification of correctness, and endorsement of transactions; ii) order and consensus protocol; iii) validation against application-specific confidence assumptions, avoiding concurrency problems (Manevich et al, 2021;Ruan et al, 2020).…”

“…The nodes perform an atomic transmission protocol resulting in an ordered sequence of output strings grouped into blocks. (Manevich et al, 2021). The transaction flow is anchored in consensus; each originator uses the same block formation protocol to group transactions into blocks and forward them to the nodes.…”

Blockchain technology combined with Data provenance is one way to make soil data more trustworthy and traceable by providing tamper-proof information about the origin, transformations, and history of pieces of data. We present Hyperledger Fabric of FAIRCHAIN, a computational infrastructure that manages smart contracts that uses soil data. We aim to mitigate the open challenges of the agricultural food supply chain, specifically in the difficulty of traceability of soil data. In this work, we present the mechanism to structure a smart contract using soil data enriched with retrospective provenance metadata. The infrastructure can hold workflow implementations.

“…In recent years, the popularity of blockchains as a means of payment and asset transfer has increased significantly. The public perception of blockchain technology has evolved from initial unawareness and suspicion to current optimism about the potential for decentralized asset management [1]. The technology is also expanding on its use cases, facilitating intermediation among mutually untrusted entities.…”

Hyperledger Fabric is a leading permissioned blockchain platform known for its flexibility and customization. A crucial yet often overlooked component is its state database, which records the current state of blockchain applications. While the platform currently supports LevelDB and CouchDB, this study argues that there is an unmet need for exploring alternative databases to enhance performance and scalability. We evaluate RocksDB, Boltdb, and BadgerDB under various workloads, focusing on memory and CPU utilization. Our findings reveal that each alternative outperforms the existing options: RocksDB excels in throughput and latency, Boltdb minimizes CPU usage, and BadgerDB is most memory-efficient. This research not only provides a roadmap for integrating new state databases into Hyperledger Fabric but also offers critical insights for those aiming to optimize enterprise blockchain systems. The study underscores the significant gains in scalability and performance that can be achieved by reconsidering the choice of state database.
