...dvent of blockchain technologies, the requirement of such trust in a central authority is eliminated. Instead, a decentralised network can be established, acting as a distributed, tamper-proof ledger [6]. Thus, leveraging blockchain technology in a data provenance solution for the IoT is a promising choice [6]. The IoT is characterised by a multitude of use cases and potential application areas [1]. ...

...Tendermint [32] provides BFT tolerance and is similar to the PBFT algorithm; however it provides a tighter guarantee with regards to the results returned to the client when more than one third of the nodes are faulty, and allows for a dynamically changing set of set of validators, and leaders that can be rotated in a round-robin manner, among other optimizations [33]....
