On B2B and B2C relations, the reliability among stakeholders is an essential requirement. Every second of every day, businesses exchange items with suppliers, partners, customers and others. Items mean goods, services, money, data and more. Such exchanges are transactions, that need to be reliable, precise and agreed among the participants. Moreover, in many transactions, the fully automation is not possible, it is needed a trusted centralized entity. In many cases, the human intercession is needed to certify the proper execution of such transaction (audit, public notaries, third-party certifier…). Blockchain aims to enable automatic transactions, reducing the "trust tax" among stakeholders. It is being used in more and more domains. However, Blockchain cannot fully ensure that the digitally recorded information is taken in a certain location and time. The automated and trusted Proof of Location has not been fully achieved without the human intercession. A reliable and affordable source of positioning/timing data is essential to achieve the automated verification of location and time. The new service Open Service Navigation Message Authentication (OS-NMA) of Galileo will provide authentication of the navigation data, in order to determine if the data used for processing was produced by the satellites or falsified. The overall goal of SPACE4GREENERis to propose a technological solution that enable a trusted platform among stakeholders of different nature for the automated certification that an activity occurs or a thing is in a location in a certain point of time, without requiring a third-party human certification. The solution is based on the integration of Galileo OS-NMA signals and Blockchain with smart devices and mobile platforms that will produce a trusted information and share it among the stakeholders. The benefit of such approach is applicable to multiple domains, but the technical validation will be focused on Agrifood and fishing scenarios.
