Internet of Entities (IoE): A Blockchain-based Distributed Paradigm for Data Exchange between Wireless-based Devices

The exponential growth of wireless-based solutions, such as those related to the mobile smart devices (e.g., smart-phones and tablets) and Internet of Things (IoT) devices, has lead to countless advantages in every area of our society. Such a scenario has transformed the world a few decades back, dominated by latency, into a new world based on an efficient real-time interaction paradigm. Recently, cryptocurrency has contributed to this technological revolution, whose fulcrum is a decentralization model and a certification function offered by the so-called blockchain infrastructure, which makes it possible to certify the financial transactions, anonymously. This paper aims to indicate a possible approach able to exploit this challenging scenario synergistically by introducing a novel blockchain-based distributed paradigm for data exchange between wireless-based devices defined Internet of Entities (IoE). It is based on two core elements with interchangeable roles, entities and trackers, which can be implemented by using existing infrastructures and devices, such as those related to smart-phones, tablets, and IoT systems. The employment of the blockchain-based distributed paradigm allows our approach ensuring the anonymization and immutability of the involved data, which is key in many scenarios and domains (e.g. financial applications, health and legal applications dealing with personal and sensitive data), requirements more and more searched in recent innovations. The possibility to exchange data among a huge number of devices gives rise to a novel and widely exploitable data environment, whose applications are possible in different domains, such as, in Security, eHealth, and Smart Cities.
