Air cargo involves large-scale data and multiple stakeholders, i.e., airports, airlines, agents, and clients. How to enable stakeholders to share data in a secure way is essential, since it improves efficiency for various processes among stakeholders. This paper proposes AirCargoChain, a blockchain-based data sharing approach for air cargo, which has the following advantages: (a) secure: we propose a blockchain-based cooperative network architecture, Cooperative Network (CN), to allow mutually distrusted stakeholders to manage data collaboratively. (b) scalable: we design a storage scheme, Off-Chain Storage (OCS), based on IPFS to support large-scale data storage; (c) user-friendly: we provide effective communication mechanism and convenient contract name service in Node Communication (NC) and Contract Management (CM), respectively. A comprehensive evaluation offers insight into the applicability and effectiveness of AirCargoChain.

空运货物涉及大规模数据和多个利益相关者，即机场，航空公司，代理商和客户。如何使利益相关者以安全的方式共享数据至关重要，因为它可以提高利益相关者之间各种流程的效率。本文提出了AirCargoChain，这是一种基于区块链的航空货运数据共享方法，具有以下优点：（a）安全：我们提出了一种基于区块链的合作网络架构Cooperative Network（CN），以允许互不信任的利益相关者共同管理数据。（b）可扩展性：我们基于IPFS设计了一种存储方案，链外存储（OCS），以支持大规模数据存储；（c）用户友好：我们分别在节点通信（NC）和合同管理（CM）中提供有效的通信机制和便捷的合同名称服务。全面的评估可深入了解AirCargoChain的适用性和有效性。
