aircargochain: a distributed and scalable data sharing approach of blockchain for air cargo

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.
