Purpose-Built Distributed Ledgers

Abstract

This chapter explains the opportunity to present some of the platforms that have earned a reputation from both industry and academia. It discusses some emerging blockchains that have the potential to disrupt the industry in the future. Existing public ledgers such as Bitcoin and Ethereum are not fast enough to provide adequate support to applications that require a response in the fraction of a second. IOTA is a distributed ledger designed for the Internet of Things (IoT). It provides secure communications and payments between IoT devices and will soon have a smart contract service called Qubic. Hyperledger is a collaborative attempt between IBM and Linux Foundation to build an enterprise-grade, open-source distributed ledger framework. The Indy platform supports independent identities on distributed ledgers and provides the necessary tools, libraries and reusable components for implementing digital identities rooted on blockchains or other distributed ledgers.
