Land clearing services are quickly spreading, mostly due to legal requirements imposed on field owners to force them to clean their terrains in order to prevent the spread of eventual wildfi res. These land clearing services are traditionally made with the help of machinery or chemicals, which is costly and heavy on the environment. An alternative is a process which is not a novelty in itself - bringing grazing animals, usually sheep, to the terrain, and have them eat the unwanted weeds. This is a cheaper and more environmental-friendly way of conducting a land clearing service. In order to increase the eficiency of this process, the SheepIT project was created, which brought the possibility of exerting a better control over the animals with the use of smart devices, which also enable valuable data collection. This dissertation is built on top of the SheepIT project and aims at being the bridge between owners of fields who intend on paying for these services, and the owners of sheep acting as service providers and looking to nd clients. The goal is to create a platform where they can publicize their intents, contractualize services and manage them. Blockchain technology was then used in order to guarantee the provenance and integrity of important data Flowing through the system, in order to generate trust between all the users of the platform.
