In this paper we take a first step towards that goal by designing Hybrid-IoT, a hybrid blockchain architecture for IoT. In Hybrid-IoT, subgroups of IoT devices form PoW blockchains, referred to as PoW sub-blockchains. Then, the connection among the PoW sub-blockchains employs a BFT ...
Blockchain technology is increasingly being used in the internet of things (BCoT: Blockchain for IoT) to ensure the security and reliability of data exchanged between connected devices. There are several generic blockchain architectures for IoT that differ in their network and consensus characteristics...
Technologies such as blockchain provide a potential solution to enable secure and effective management of IoT data communication in a distributed and trustless manner. In this paper, a novel lightweight blockchain-centric IoT architecture is proposed to address effective IoT data communication management...
The blockchain-based architecture provides linked devices with minimal and decentralized security solutions. Moving freight is a complex process comprising several parties with variable priorities in freight transportation applications. An IoT-driven blockchain can record the arrival times, the status of ...
Our main contribution is a fully decentralized architecture that combines blockchain and traditional distributed database to gain additional features such as efficient query and retrieval of metadata stored on the blockchain.doi:10.1007/978-3-319-76451-1_33Obaro Odiete...

While the intersection of DLT and IoT is a critical technological convergence to watch, and one that may provide an architecture for trust in autonomous products and services, businesses must take a sober approach. Blockchain is not a panacea or a solution to all IoT (nor IT) inefficiencies....
We propose a blockchain and fog-computing-enabled security service architecture that operates on fog nodes at the edge of manufacturing equipment clusters. The proposed service facilitates CM equipment authentication and equipment-cloud channel privacy protection while preserving anonymity and unlinkability ...
First, the proposed architecture uses SDN to continuously monitor and analyze traffic data in the entire IoT ecosystem, thus mitigating the issue of data unavailability in security detection and providing optimal security defense. Second, the architecture employs the Blockchain Declaration of interests ...
Here we will introduce the notion of Reputation Capital. In this approach, the reliability of a consumer is guaranteed by the blockchain (in this case, it must pay the service to another agent), while the reputation capital of a provider witnesses its ability to provide quality service. ...
