DLT Architecture Proposal for IoT Applications Based on Data Streams

Millions of sensor-based devices are now continuously transmitting data, which is key for solving real-world situations. In the modern era, devices and their generated data streams are crucial because of their low cost combined with east implementation. Despite the ease with which both devices and their data streams may be altered, the processes required to transfer data collected to final analysis—which involve data transformation and variable creation—present a significant issue to research since such data must be secured in applications. Systems can be endowed with characteristics like resilience against the advent of single points of failure or resistance to information manipulation by means of distributed ledger technologies (DLT). DLT has the capacity to create sensor-based solutions with properties that would enable the creation of a broader variety of potential solutions. This contribution introduces a platform for gathering data streams from sensor-based devices and publishing them on a DLT infrastructure (DLTI). We present and justify the platform’s interface layers, i.e., data gathering and publication on a DLTI.
