21.10.2020 As a decentralized and distributed technology, blockchain provides a new solution to the problems that exist in IoT authentication [28, 34, 35].As in Figure 1(b), blockchain-based authentication schemes decentralize IoT authentication by establishing a blockchain network at a gateway or authentication server in the system to achieve distributed management of the authentication process. For many applications, this combination of security and performance enables a new defense to DDoS attacks, even those that leverage IoT devices. To demonstrate the point, let's consider a popular blockchains as a storage layer and introduces a database layer on top that extends blockchains by classical data man-agement techniques (e.g., sharding) as well as a standardized query interface to facilitate the adoption of blockchains for data sharing use cases. We show that by introducing the additional database layer, we are able to improve 04.04.2016 28.01.2018 28.11.2020 Blockchain And IoT: A Perfect Match? Let’s start with Bitcoin’s extensive global blockchain ledger footprint.

As various companies, projects and individuals begin thinking about ways to apply blockchains to the IoT and Smart Systems, we’ll … 01.09.2018 04.06.2019 Projects like IOTA have come along with new IoT-specialized blockchains or blockchain-like technologies to tackle many of these issues. Considering that the world volume of IoT devices is expected to exceed 70 billion devices by 2025, it seems likely that these issues will get more attention and research. security concerns and scalability issue. In this paper, we pro-pose HIBEChain, a hierarchical blockchain system that realizes scalable and accountable management of IoT devices and data. HIBEChain consists of multiple permissioned blockchains that form a hierarchical tree structure. To support the hierarchical These will need to be worked on over the next few quarters before we see production grade IoT deployments on Blockchains. Topics: iot, blockchain, industrial internet, smart cities.
