论文摘要
区块链技术为信息记录提供了可审核和防篡改的分布式存储基础架构。可以利用这来支持分布式工作流程管理。与工作证明共识相比，比特币和以太坊普及的是基于BFT（拜占庭容错）的区块链，以达成共识贸易可伸缩性，以达成共识和最终达成共识。这使它们更易于用作分销基础架构，因为不需要适应应用程序来处理最终的一致性和延迟工作证明区块链的共识。因此，诸如工作流引擎之类的应用程序可以轻松移植到这种区块链基础架构上，以利用其分散的完整性保证和信息分配模型。在本文中，我们描述了如何在基于BFT的区块链基础架构上使用Yawl Workflow引擎，以启用不同组织的协作工作流程。
Blockchain technology provides an auditable and tamper-proof distributed storage infrastructure for information records. This can be leveraged to support distributed workflow management. Compared to proof-of-work consensus, popularized by Bitcoin and Ethereum, blockchains based on BFT (byzantine fault tolerance) ordering consensus trade scalability for immediacy and finality of consensus. This makes them easier to use as distribution infrastructure, as applications need not be adapted to deal with eventual consistency and delayed consensus of proof-of-work blockchains. Hence, applications such as workflow engines can be easily ported to such a blockchain infrastructure to take advantage of their decentralized integrity assurance and information distribution model. In this paper we describe how the YAWL workflow engine can be used on a BFT based blockchain infrastructure to enable collaborative workflows across different organizations.
