Blockchain can record data in a decentralized, secure ledger. Smart Contracts are a novel technology extending blockchain capabilities. It allows secure automated execution of business logic inside the blockchain. The increase in connectivity for connected devices allowed blockchain and smart contracts to create new secure and automated...

The Internet of Things (IoT) has revolutionized the way devices interact and communicate with each other. As the number of IoT devices increases, there is a growing need for secure and reliable communication protocols. Blockchain technology has emerged as a promising solution to ensure secure and trustworthy communication in IoT networks....

The study presented in this paper demonstrates the potential of blockchain technology to address some of the challenges present in the automotive domain, particularly in terms of providing secure and efficient data handling for real-time vehicle accident data storage. We propose an implementation on Android Automotive OS using a Substrate-based...

In this paper, we will present a new model of distributed ledger-based IoT network, in which we combined Hyperledger Sawtooth as blockchain with InterPlanetary File System (IPFS) as a distributed storage system. The combination of these two types of distributed ledger technologies can allow more efficient data storage than in other blockchain...

We want to study the adaptability of blockchain technology on IoT devices. In this paper we studied Hyperledger Sawtooth adaptability on a Raspberry Pi 3 B+ depending on the requirements of a special use case described by our industrial partner Renault. In addition to the study of Hyperledger Sawtooth adaptability, we modified the model of the...

We present Hyperledger Sawtooth performance results using an industrial use case implementation, which contains blockchain as the immutable data storage and IoT devices sending transaction to the blockchain. Throughput and transaction execution latency is extracted from a benchmark on a local blockchain setup. An API is also implemented to...

Recent literature claims that blockchain technology (BCT) has the potential to enhance interorganizational data sharing. Yet, in practice, BCT's implementation faces challenges which partly explain companies' reluctance to adopt BCT in their existing interorganizational environment. This is particularly striking in some economic sectors, such...

This paper presents a blockchain cloud deployment for an industrial vehicle use case. Hyperledger Sawtooth is used as distributed ledger with Rancher and Kubernetes as container-orchestration. This paper aims to explore the feasibility and scalability of the use case in a real-world scenario cloud deployment. Also, the blockchain performances...

We present in this work a Lightweight Transaction Protocol (LTP) for enabling constrained embedded devices' interaction with multiple types of blockchains via the LoRaWAN communication protocol. The proposed protocol provides the benefit of interacting with multiple blockchains with only 13.5% decrease in battery life. The protocol also...

Private or consortium blockchain networks have fewer verified participants and offer better throughput and transaction efficiency than public networks. However, as more and more blockchain consensuses are designed for private or consortium networks, their performances are often estimated without a practical use case implementation. In our use...
