The use of blockchain (BC) technology for IoT-based collaboration platforms is still hindered by its inherent properties, namely, the need for everincreasing storage and the low scalability. In this paper, we investigate the interoperability requirements between BC and tangle distributed technologies. We propose a new decentralization architecture in which BC and tangle are combined in such a way that the IoT functionality is increased, and storage is enhanced while keeping a high level of reliability, data accessibility, integrity, and security. In our architecture, a BC-based platform installed in the backend, used primarily for data storage and smart contract. In the frontend, the applications are running on a Tangle-based platform so that it fits IoT devices. The architecture, when implemented, will reap the advantages of both technologies while limiting the drawbacks of them. The main part of the proposed approach has been implemented and tested using a GPS data emulator connected to an IOTA node. The received data have been propagated and stored in the deployed BC and IOTA.
This paper presents the design and implementation of a new platform that takes into consideration the requirements and constraints resulting from the industrial context based on IoT. This platform combines the “Tangle” and “Blockchain” techniques. Tangle is primarily designed to address scale-up issues and the relatively high cost (time and resource) of transactions in a traditional blockchain-based platform. Unlike the “blockchain” structure, it consists of a solid mathematical foundation called DAG (Direct Acyclic Graph). It uses a validation process in which transactions are entered into the distributed registry after authenticating two other randomly selected transactions according to a Poisson distribution (thus, the locations of the new transactions are chosen using random runs in the graph). Therefore, it is an easily scalable system that does not require mining or transaction fees. We aim to study the integration of Tangle and Blockchain techniques to improve the performance and scalability of distributed registry-based platforms to be adapted in industrial enterprises whose processes incorporate or are based on IoT.
