区块链已经成为一种流行的技术,可以降低交易各方之间的信任税负担,而这些交易方不一定相互信任。它们被用作交易工作流程中通常包含的中央当局的替代品,以执行核查任务,并具有客观和廉洁的优点。对于供应链市场等应用程序,除了记录和验证交易(如事件检测)的核心区块链角色之外,辅助功能对于使应用程序参与者能够响应业务条件非常重要。不幸的是,现有的区块链事件框架是不成熟的,语法,不灵活的,没有足够的表达能力,许多应用程序的需求,在本文中,我们提出了一种方法,涉及一个事件模型,“语义化的区块链交易”和实现架构,集成了一个开源的区块链数据库BigChainDB与语义引擎和订阅消息平台。最后,我们建模和模拟一个用例的灵感来自制造领域,目前的可用性和初步的性能结果,证明语义启用的事件模型的区分能力。
Blockchains have become a popular technology for lowering the trust-tax burden between transacting parties that cannot necessarily trust each other. They are used as substitutes for the centralized authorities typically incorporated in transactional workflows to perform verification tasks and have the advantage of being objective and incorruptible. For applications such as supply chain marketplaces, auxilliary functionalities beyond the core blockchain roles of recording and validating transactions such as event detection are important for enabling application participants be responsive to business conditions. Unfortunately, existing blockchain event frameworks are immature, syntactic, inflexible and not expressive enough for many application needs.In this paper, we propose an approach that involves an event model which "semantifies blockchain transactions" and an implementation architecture that integrates a open-source blockchain database BigChainDB with a semantic engine and publish-subscribe messaging platform. Finally, we model and simulate a use-case inspired from the manufacturing domain and present usability and preliminary performance results that demonstrate the discriminatory ability of semantics-enabled event model.
