论文摘要
区块链是一种分布式技术，它允许在互动和执行交易的不可靠用户之间建立信任。尽管区块链技术主要用于加密货币，但它已成为建立对物联网领域（IoT）的信任的促成技术。然而，对物联网的区块链的幼稚用法会导致较高的延迟和广泛的计算能力。在本文中，我们提出了一个专门用于包含不同分布式物联网实体的供应链中的区块链体系结构。我们提出了该架构的轻量级共识，称为LC4IOT。共识是通过广泛的模拟来评估的。结果表明，所提出的共识使用低计算能力，存储能力和延迟。
The blockchain is a distributed technology which allows establishing trust among unreliable users who interact and perform transactions with each other. While blockchain technology has been mainly used for crypto-currency, it has emerged as an enabling technology for establishing trust in the realm of the Internet of Things (IoT). Nevertheless, a naive usage of the blockchain for IoT leads to high delays and extensive computational power. In this paper, we propose a blockchain architecture dedicated to being used in a supply chain which comprises different distributed IoT entities. We propose a lightweight consensus for this architecture, called LC4IoT. The consensus is evaluated through extensive simulations. The results show that the proposed consensus uses low computational power, storage capability and latency.
