10 min readAug 28, 2023


Since September 2020, FIWARE Foundation has been leading the successful i4Trust project around Data Spaces, which has been receiving funding by the European Commission under the Grant Agreement of 951975. Thanks to the extraordinary collaboration of partners such as iShare and FundingBox, 32 selected solutions on Data Spaces have been awarded and funded. With the first impacting results available, FIWARE has decided to publish a fine selection of Impact Stories showcasing FIWARE-based solutions created by an awarded and funded consortium of DIHs (Digital Innovation Hubs) and SMEs. The CollMi experiment addresses two common issues in logistics operations: The absence of a unified digital communication mechanism between different entities and The lack of trust between logistics companies. These issues have been causing many errors and have been hindering the implementation of efficient and sustainable practices.

Challenge & Context

The rise of e-commerce and the increasing consumer demand for rapid delivery has placed considerable pressure on the logistics industry to improve their efficiency in both urban and rural areas. Municipalities are also concerned about the negative impact of increased parcel deliveries on traffic, congestion, and pollution in urban centers, and are seeking sustainable solutions.

Collaborative Micro-Hubs (CMHs) represent a new logistical concept that utilizes advanced game theory methodologies. In this model, a group of logistics companies, including express and freight forwarders, collaborate by sharing resources to deliver parcels from a network of common logistics centers located in strategic areas of urban centers. The primary incentives for logistics companies to operate within a CMH include cost reduction, improved service quality, and wider geographical coverage without large initial investments and risks.

TheCollMi experiment addresses two common issues in logistics operations that cause many errors and hinder the implementation of efficient and sustainable practices, such as those utilized by CMHs.

These problems are:

  • The absence of a unified digital communication mechanism between different entities involved in the logistics value chain, such as senders, recipients, forwarders, shippers, consignees, and receivers. Typically, unstructured email messages are used to exchange information about the parcel’s whereabouts and to agree on important details of shipping, such as pickup locations and times, customs clearance procedures, and delivery dates and locations. There is an urgent need for an easy-to-use platform that provides intelligent EDI processes, which take into account the needs of smaller companies that cannot afford the typically large investment of custom logistics management systems. The main challenge is to develop a common data model with integrated authentication and authorization that meets the data needs of each entity and respects different privacy requirements and data-sharing processes.
  • The lack of trust between logistics companies, that hinders the implementation of collaborative operations that could benefit both companies and the entire logistics process. The main obstacle is that logistics companies find it difficult to trust a third-party entity that manages data-sharing platforms because of the potential damage that such an entity could inflict in the case of a malicious action. A possible solution to this problem is to use distributed ledger technology with appropriate consensus mechanisms that ensure all parties validate the exchanged data and prevent future changes.


Despite the recognized commercial and environmental advantages of collaborative micro-hubs, implementing them is a complex challenge in terms of business technology. Success depends on the ability to provide credible solutions for different transport operators to exchange information and execute operations shared with each other. Smart contracts, based on blockchain technology, are chosen as essential elements to support the adherence of operators to the platform.

This project aims to develop a practical solution to this problem, by using blockchain technology, specifically distributed ledger technology. The goal is to implement a robust digital solution that solves the collaboration and trust issues that limit the implementation of collaborative micro-hubs. Blockchain technology has the potential to record all transactions of the micro-hub, last-mile carriers, freight forwarders, and sellers, in a verifiable, permanent, and transparent way for all interested parties.

The role of the i4Trust initiative in this project is to provide a reliable data-sharing framework with trustworthy access control. The framework ensures that each retailer only has access to package information for their own orders or their clients’ orders. Each logistics operator can access package information relevant to their operation, whether it is their own orders or those they were subcontracted to deliver.

The CollMi experiment introduces collaborative logistics micro-hubs that foster co-opetition among traditional market competitors, representing a significant conceptual innovation. The benefits of this project extend beyond the entities directly involved in the operations, with spill-over effects including reduced traffic and air pollution, benefitting the wider community. The main technological contribution of the project is the integration of distributed ledger technologies, iShare, and FIWARE components to implement smart data models and operational trusted data sharing processes.

The retail industry has long awaited a reliable source of information to track the whereabouts of incoming and outgoing goods, irrespective of the specific freight forwarders, last-mile carriers, subcontracted companies, and government agencies involved in the process. The proposed solution offers important efficiency gains, such as eliminating the need to make multiple phone calls or manually access the digital platforms of each entity involved in the supply chain to track parcel status. The solution provides more reliable information to customers about their purchases and future availability of out-of-stock goods. It also allows them to compare the performance of logistics operators and make strategic business decisions.

How it works

Figure 1 . Architecture

The experiment architecture categorizes logistics operators into two types:

The LMD operator is contracted by the retailer to deliver goods directly to the final client, while the FF is a subcontracted third party for a portion of the route. Logislink assumes both roles and will implement the components for the LMD since they include everything needed by the FF. Each LMD operator will run its own instance of a FIWARE Context Broker (Orion LD) and a MongoDB database containing relevant context data for packages they were contracted to deliver.

Similarly, the Smart Islands Hub (SIH) will also run an instance of a FIWARE Context Broker, referred to as shared Context Broker. Context Broker will subscribe to waybills related to the collaborative microhub present in the context brokers implemented by the LMDs and serve as the primary context information provider for all participants, retaining information regarding handoff operations. Access to these context brokers will be protected by instances of Kong, a gateway proxy, in each logistics operator and the SIH.

Once all participants are registered as iShare parties, package context information (waybill) is then provided via the shared context broker to retailers and contracted LMDs, using iShare compliant access policies for identification, authentication, and authorization. The experiment’s retailers are Loja do Chá, an online shop, and Weasy, which acts as a proxy for all online shops under their umbrella and offers them a plugin to access their respective client package information. The FF and other LMD’s contracted to deliver within the micro hub will also obtain package context information assigned to them via the shared context broker to obtain the necessary information for their legal transport document.

The retailers, LMDs, and FFs, will subscribe to waybill entities of the LMDs they work with via the shared context brokerand have access only to those entries where they are listed as the trader or transporter for that leg of the delivery. Any changes to those entries will trigger notifications. The final customer can track their delivery status on both the online shop’s website (in their authenticated area) and the LMD’s website (unauthenticated) using a unique identifier provided by the LMD and passed on by the retailer.

All LMDs and the SIH will implement FIWARE’s Identity Manager Keyrock, and retailers will use the identity provider at the shared context broker (SIH) for authentication.

Benefits & Impact

CollMi is a B2B digital platform that enables logistics companies to share deliveries with one another.

The platform has two typical use cases. Firstly, companies without the necessary resources or interest in making a delivery can offer it to another logistics company on the platform. Secondly, a logistics company experiencing a period of low activity can use the platform as a source of deliveries. These situations are common among logistics companies, especially smaller ones. However, CollMi transforms these problems into business opportunities, increasing the productivity of logistics companies. Currently, no other platform on the market provides such a service, making the opportunity quite unique.

ColliMi’s proposed experiment involves collecting data on the costs, time, and participant feedback from the new processes enabled by the data sharing platform. The results will demonstrate significant benefits for all stakeholders. These benefits include lower delivery costs, shorter delivery times, wider geographical coverage, more detailed and accurate information for end customers, reduced traffic, and decreased carbon emissions.

The experiment will also create qualified jobs in the logistics sector by opening a number of new positions to manage and monitor micro-hub operations, while reducing the number of unqualified and lower-paying jobs, such as delivery couriers and drivers. ColliMi anticipates a significant increase in this effect in the near future as companies and end-customers become more aware of the need to reduce carbon emissions and adopt responsible consumption behaviors, leading to a greater demand for collaborative micro-hubs.

The cooperative relationship between companies within the micro-hub opens up new opportunities for smaller logistics companies to operate and compete with larger market owners. This should help cultivate a more equitable economic landscape where wealth is shared among a greater number of companies and their associates.

All SMEs involved in this experiment can leverage these benefits to increase their sales. However, SMEs in the logistics and software development sectors stand to gain the most, with sales expected to increase by over 30%, according to the author’s opinion. Logistics companies will be able to accept more deliveries and relay them to partners via the micro-hub, receiving a fee in the process. They can also accept deliveries from other operators within the micro-hub’s market. Software development SMEs can meet their sales objectives by developing and maintaining logistics software management projects integrated with the micro-hub platform.

Next steps

CollMi’s consortium recognized that, possibly through third party software, data generated by the platform could be supplemented with data from individual logistics operators. This could then be used to create a recommendation engine that advises companies in advance on which deliveries they should outsource to other companies, and which deliveries they should bid on, at what amount, and quantity. This would not only automate the interaction of logistics companies with the marketplace, it would also provide companies with a mechanism to increase the automation level of their entire logistics operation.
