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 […]
Ethereum Blockchain (EBaas) as a Service provided by Microsoft Azure and ConsenSys allows for enterprise customers and partners to play, learn, and fail fast at a low cost in a ready-made dev/test/production environment. It will allow them to create private, public and consortium based Blockchain environments very quickly in Azure. In this session, you will learn how to get started with prototyping building blocks of a decentralized application using EBaas in Windows Azure. Venue: Triangle Azure User Group Slides : download.
Smart Contracts are an exciting innovation built on blockchain technology. It is a way to execute code in a trustless, decentralized and transparent system. Ethereum is a decentralized platform to run smart contracts using a variation of Bitcoin’s blockchain technology. In this session, you will learn how to write smart contracts in Visual Studio. You will learn how to deploy them to public Ethereum blockchain and a private/consortium blockchain as a service in Azure. You will be introduced you to Solidity – the programming language used to write smart contracts. You will get familiar with the tools and technology around this exciting, promising and relatively new innovation. Presentation Slides are here: download.
