Blockchain and Internet of Things data provider for smart applications


This paper describes the use of blockchain technology as a data provider in Internet of Things (IoT) applications. Blockchain is a novel technology, which has gained a lot of attention in the last years, mainly due to its use as a backbone for cryptocurrencies. The main purpose of blockchain technology is to provide anonymous transactions between participants, over a peer-to-peer network, using a decentralized distributed ledger. The goal of this novel approach is to eliminate any 3 rd party validation and replace the trust of a central authority for transaction validation with cryptographic proof. While most applications of the blockchain revolve around cryptocurrencies, the blockchain can be used in many other fields, such as finance, distributed data storage, health and medicine, automation, etc. By creating an open, decentralized network, the blockchain can be used to develop decentralized applications and enable data access and sharing on a much higher level than the common implementations of client-server architectures which are in use today. In this paper, we will present a proof of concept method for field devices to store and share data using a distributed ledger built on the IOTA tangle, as well as provide means of access to the data which can be used in IoT and decentralized applications.
