Supply chains play today a crucial role in the success of a company’s logistics. In the last years, multiple investigations focus on incorporating new technologies to the supply chains, being Internet of Things (IoT) and blockchain two of the most recent and popular technologies applied. However, their usage has currently considerable challenges, such as transactions performance, scalability, and near real-time contract verification. In this paper we propose a model for continuous verification of contracts in supply chains using the benefits of blockchain technology and real-time data acquisition from IoT devices for early decision-making. We propose two platform independent optimization techniques (atomic transactions and grouped validation) that enhances data transactions protocol and the data storage procedure and a method for continuous verification of contracts, which allows to take corrective actions to reduce operational costs and increase benefits in current supply chains. An automatic deployment of a large scale distributed business logic system using virtualized appliances is also proposed. Evaluation results show the feasibility or the solution proposed.

今天，供应链在公司物流的成功中起着至关重要的作用。在过去的几年中，多项调查着重于将新技术整合到供应链中，其中包括物联网（IoT）和区块链这两种最新最流行的技术。但是，它们的使用目前具有相当大的挑战，例如交易性能，可伸缩性和接近实时的合同验证。在本文中，我们提出了一种利用区块链技术和从IoT设备实时获取数据以进行早期决策的持续验证供应链合同的模型。我们提出了两种独立于平台的优化技术（原子交易和分组验证），这些技术可以增强数据交易协议和数据存储过程，以及一种连续验证合同的方法，可以采取纠正措施来降低运营成本并增加当前供应链中的收益。还提出了使用虚拟化设备的大规模分布式业务逻辑系统的自动部署。评估结果表明了可行性或提出的解决方案。
