Abstract

Distributed Ledger Technologies (DLT), of which Blockchain is a popular example, are increasingly becoming an integral feature of many modern systems.While cryptocurrencies are a common motivating example, and they drive systems such as Bitcoin, DLT has many other uses across industries including Health Care, Supply Chain, IoT, and Finance among others.One of the key concepts that make DLT appealing is the ability for large-scale systems that do not trust each other to reach consensus and share a commonly verifi able ledger, in order to track resources, changes to system-wide data, and other artifacts.Cryptocurrencies are one type of resource that can be tracked, but DLT has been used for energy, pharmaceuticals, and many other domains.
