Getting started with Blockchain

tewari

Washington DC – May 2019 In this session, we will introduce you to the world of Blockchain technology. We will start with the fundamentals and explain the characteristics and use cases of Blockchains and Decentralized applications. We will explain public Blockchains as well as permissioned Blockchains – with examples from Ethereum and Hyperledger. You will learn how to create a private blockchain to get started. You will learn about Ethereum and how to program Smart Contracts for Ethereum Blockchain. We will also share best practices for secure and effective Smart Contracts development.

Blockchains for Enterprise

Permissioned blockchains are being developed and used in Enterprise scenarios in which higher transaction throughput, lower latency, versatile confidentiality and governance models are more important than supporting low trust levels among participants. These Enterprise requirements are not being met adequately by the public and permission-less blockchain ledgers. Enterprise scenarios typically have known actors and the trust level between these actors is very high. This allows for trade-offs between trust levels and transaction throughput, speed, confidentiality and privacy, which in turn enables alternate solutions via permissioned blockchains. Hyperledger Fabric (referred to as ‘Fabric’ in the rest of this article) is the leading permissioned blockchain framework, initially developed by IBM. There are other players in this space, including Multichain, ChainCore and the relatively […]
