Blockchain technology provides basic building blocks to support the execution of collaborative business processes involving mutually untrusted parties in a decentralized environment. Several research proposals have demonstrated the feasibility of designing blockchain-based collaborative business processes using a high-level notation, such as the Business Process Model and Notation (BPMN), and thereon automatically generating the code artifacts required to execute these processes on a blockchain platform. In this paper, we present the conceptual foundations of model-driven approaches for blockchain-based collaborative process execution and we compare two concrete approaches, namely Caterpillar and Lorikeet.

协作业务流程的区块链支持

区块链技术提供了基本的构建块，以支持在分散的环境中执行涉及相互不信任方的协作业务流程。几项研究建议证明了使用高级符号（例如业务流程模型和符号（BPMN））设计基于区块链的协作业务流程的可行性，并在此之后自动生成在区块链平台上执行这些流程所需的代码工件。在本文中，我们为基于区块链的协作流程执行提供了模型驱动方法的概念基础，并比较了两种具体方法，即Caterpillar和Lorikeet。
