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.

GreenFit is a collaborative project uniting research institutions, technology developers, agricultural practitioners, and field actors to tackle the barriers limiting farmers from adopting climate-smart practices. Through a combination of advanced technologies such as AI-powered decision support systems, IoT sensors, and XR-based training tools, GreenFit focuses on optimizing resource use, enhancing decision-making, and building resilience to climate change. The project also promotes value-chain partnerships and strengthens digital infrastructure, ensuring scalability and sustainability. Through the use of real-time tools, including the LLM-based AgriChatbot and a drone-in-a-box system for soil analysis and crop health monitoring, GreenFit empowers farmers with the practical, innovative solutions needed to transition toward sustainable practices. GreenFit focuses on capacity building and community-driven dissemination, communication, and exploitation, as through hands-on training, workshops, and stakeholder engagement, it empowers local communities to adopt and sustain climate-smart practices. The project’s capacity-building program and knowledge-sharing platforms ensure that farmers and rural stakeholders are actively involved in the development process. GreenFit's community-led approach enhances local ownership of solutions, driving sustained environmental and economic benefits.
