Modern transportation systems, such as computer networks, have become increasingly faster, aiming to “shorten” distances and travel time. This trend allows thinking about new services and induces to reconsider existing ones starting from new technologies, as for Intelligent Transportation Systems. Thereby, an all-encompassing scenario laying at the intersection of several domains, including manufacturing, logistics, traveling, insurance, maintenance, and trading, with the transportation one, can be envisioned. The building block for the resulting transportation ecosystem is an information system that is able to gather and connect all involved stakeholders and domains around the concept of mobility and vehicle to address complex multifaceted problems in an efficient and trustworthy way. This paper proposes the adoption of distributed ledgers to implement such a vehicle-centric information system, distributing data across the network while ensuring trustworthiness. Starting from the vehicle lifecycle immutable and certified information, new services for cross-cuttingly addressing diversity and complexity in the transportation ecosystem can be implemented. The proposed solution merges Multichain and MongoDB technologies to achieve a trade-off between trustworthiness and performance, storing only the metadata in the Multichain network. Its effectiveness is demonstrated by an example on a vehicle trading service showing an overhead for the proposed solution below 18% against a pure MongoDB one on I/O operations.

运输生态系统的可信赖性：区块链车辆信息系统

现代交通系统，例如计算机网络，已经变得越来越快，旨在 “缩短”距离和旅行时间。这种趋势允许思考新服务，并促使人们从新技术开始重新考虑现有服务，例如智能运输系统。从而，可以设想在运输，运输，制造，物流，旅行，保险，维护和贸易等多个领域相交的情况。最终的运输生态系统的构建块是一个信息系统，该信息系统能够围绕出行和车辆的概念收集并连接所有相关的利益相关者和领域，从而以有效且可信赖的方式解决复杂的多方面问题。本文提出采用分布式分类帐来实现这种以车辆为中心的信息系统，在确保可信度的同时，通过网络分布数据。从车辆生命周期的不可变和经过认证的信息开始，可以实施新的服务，以跨领域解决运输生态系统中的多样性和复杂性。拟议的解决方案将多链和MongoDB技术融合在一起，从而在可信赖性和性能之间进行权衡，仅将元数据存储在多链网络中。通过一个汽车交易服务上的示例证明了其有效性，该示例显示，针对纯I / O操作的MongoDB，该解决方案的开销低于18％。拟议的解决方案将多链和MongoDB技术融合在一起，从而在可信赖性和性能之间进行权衡，仅将元数据存储在多链网络中。通过一个汽车交易服务上的示例证明了其有效性，该示例显示，针对纯I / O操作的MongoDB，该解决方案的开销低于18％。拟议的解决方案将多链和MongoDB技术融合在一起，从而在可信赖性和性能之间进行权衡，仅将元数据存储在多链网络中。通过一个汽车交易服务上的示例证明了其有效性，该示例显示，针对纯I / O操作的MongoDB，该解决方案的开销低于18％。
