SEDIMARK · October 1, 2025
D4.2

In response to the growing demand for secure and transparent data exchange, the infrastructure of SEDIMARK Marketplace leverages cutting-edge technologies to establish a resilient network.

The decentralization approach ensures increased security, transparency, and user-centric control both over different types of assets and user identity information. The SEDIMARK Marketplace leverages distributed ledger technologies to establish a resilient and scalable infrastructure. The decentralized architecture of the marketplace is built on a robust distributed ledger employed for user identity management, as well as blockchain foundation, fostering tamper-resistant contracts.


This deliverable presents the final version of the Decentralized Infrastructure employed for the SEDIMARK Marketplace and the APIs that enable the functionalities satisfying the requirements and the objectives for the Project. It represents an important capstone for every stakeholder that plans to use the Marketplace for offering assets and consuming data and services. Here, after a careful examination and design process across all the partners of the project, the final version of the SEDIMARK Marketplace is shaped and consolidated. This document stems from the previous capstone realized with Deliverable SEDIMARK_D4.1 and Deliverable SEDIMARK_D3.4 in December 2023. The current deliverable builds upon the previous version, extending its scope and functionality. This document highlights the key differences, changes, and additions made since the last iteration, providing a clear overview of the enhancements and improvements implemented in this version. Additionally, each section of the current deliverable includes context and rationale for the updates, ensuring a comprehensive understanding of the project's evolution.
