Abstract

The popularity surrounding blockchains has naturally led to research into its applicability in many areas. However, Nakamoto-style blockchains possess several characteristics that make them inappropriate for many purposes in the Internet of Things (IoT) domain. Notably, they are powerintensive and require high network connectivity. These requirements are fundamentally incompatible with IoT where nodes may have limited power and sporadic network access. We are designing a blockchain approach for IoT environments called Vegvisir. Vegvisir is a partition-tolerant blockchain for use in power-constrained IoT environments with limited network access. Under the hood, it is a membership-based, directed acyclic graph (DAG)-structured blockchain [1]. It is motivated by and ideally suited for paramedics and firefighters in disaster scenarios. For instance, it can be used to aid in many tasks during disaster response where network connectivity is poor or nonexistent; namely, it is a blockchain, so provides the abstraction of an append-only log of transactions that is tamperproof. Utilizing a distributed trust model, Nakamoto-style blockchains are free from centralized control and single

unteted:为物联网环境部署区块链

围绕区块链的流行自然导致了对其在许多领域的适用性的研究。然而，中本聪风格的区块链具有几个特点，使其不适合物联网(IoT)领域的许多用途。值得注意的是，它们是电力密集型的，需要高网络连接性。这些要求从根本上与物联网不兼容，因为物联网节点可能具有有限的功率和零星的网络访问。我们正在为物联网环境设计一种区块链方法，称为Vegvisir。Vegvisir是一款分区容忍b区块链，适用于功率受限的物联网环境，网络访问受限。在底层，它是一个基于成员关系的、有向无环图(DAG)结构的区块链[1]。它是由灾难场景中的护理人员和消防员所驱动的。例如，在网络连接较差或不存在的灾难响应期间，它可以用于帮助执行许多任务;也就是说，它是一个区块链，因此提供了一个不可篡改的事务附加日志的抽象。利用分布式信任模型，中本式区块链不受集中控制和单一
