In recent years an effort has been made to improve supply chain management (SCM) and traceability control in different industrial sectors, for example, in agriculture one of the main concerns is about to know where is the product in particular moment and where it will be next. Problem here is, as many other systems, the centralisation of information and trust problems derived from human interaction with transactions in the system. Based on this context of lack of trust, we propose the design and development of a platform using a database based on Blockchain technologies, the platform's main effort is to propose a solution for agriculture SCM and control over internet taking as study case Colombian agriculture negotiation process.
