Speaker – Ash Tewari

Getting started with Blockchain

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.

TRINUG – Programming Smart Contracts on Ethereum Blockchain

TRINUG – Main Meeting : Programming Smart Contracts on Ethereum Blockchain – August 2018

In this session, Ash will introduce you to the world of Blockchain programming. You will learn about Ethereum and how to program Smart Contracts for Ethereum Blockchain. You will learn how to deploy and test your Contracts on a public Ethereum Testnet. Ash will share best practices for Smart Contract development. You will be able to participate in a hands-on walk-through in the latter half of the session.

Charlotte IOT – Programming Smart Contracts on Ethereum Blockchain

Charlotte IOT – July 2018

You will not want to miss this chance to learn about Blockchain, a technology enabling an entire IoT ecosystem! It has a distributed database for all the transactions, which eliminates the need for the third party to authenticate the transactions. The database ledger is a continuously growing list of records, called blocks, which are linked and secured using cryptography.
Charlotte IoT wants to thank Ash Tewari for traveling from Raleigh to share his extensive knowledge and experience around Blockchain. In this session, Ash will introduce you to the world of Blockchain programming. You will learn about Ethereum and how to program Smart Contracts on Ethereum Blockchain. You will learn how to deploy and test your code on a public Ethereum Testnet. Ash will complete the session with sharing some best practices for Smart Contract development. You will be able to participate in a hands-on walkthrough in the latter half of the session.

Ethereum Blockchain-As-A-Service in Azure Cloud

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.

Getting Started with Smart Contracts on Ethereum Blockchain using Visual Studio

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.

Universal Apps

The story of Windows Universal Apps is the result of advancements in three areas:

The platform convergence between Windows 8.1 and Windows Phone 8.1
The (ongoing) unification of Windows and Windows Phone stores.
Shared Projects and other enhancements in Visual Studio 2013 Update 2 to support cross-platform development.

I have written about my experience in converting an existing Windows 8 app, CensusMapper, to a Universal App on the AIS Blog. Read the article here. I have also created another Universal App, LRMS, using Windows App Studio. This app is available in both Windows and Windows Phone Stores.

I gave a presentation at the Raleigh Code Camp this past weekend : Creating Universal Apps for Windows Phone 8.1 and Windows 8.1. Thanks to everyone who attended the presentation. The session slides for this presentation are available here : Download Slides.
