Motivation

This is the last of the 5 articles I wrote to explain how an end-to-end Balloting system on Ethereum might work. In this segment, I will explain the codes behind the Voting module of the DApp. 

This is the 4th of 5 articles to explore the development of an end-to-end Balloting system on Ethereum. In this article, I will explain the codes behind the Ballot Management module of the DApp. 

Do check back often as I work on the rest of the articles in this series.

Ethereum, Bitcoin and many other cryptocurrencies have fallen to new lows in September 2018. Vitalik Buterin, the creator of Ethereum said that Blockchain is now at the stage where we are "Go(ing) from just people being interested to real applications of real economic activity".

This article builds on the tutorial written by Michael Chan here. In his article, Michael demonstrated how to code a React.js Dapp that writes a file's IPFS hash to an Ethereum Solidity Smart Contract and stores the file in IPFS. Michael Chan's article is a great piece to follow if React.js is what you are seeking.

I have come to enjoy coding in Solidity because it offers so much in innovative features.I have written about the "_" modifier in a previous article. In this article, I wish to document what emit in Solidity does.

This is a continuation of the Going Dutch Smart Contract project that I started on 2nd Sep 2017. It has been a month, which is probably the equivalent of a year if you count in blockchain-time. Geth has gone from 1.6.7 to 1.7.2 and after upgrading my setup, I had to let it run overnight (in fast mode!) to sync my node to the block again.

Objective

This is a continuation of my post about Ethereum on the Cloud and Smart Contract execution with MetaMask. MetaMask is a Google Chrome extension and runs only on desktops. I wanted to execute Dapps on a mobile device on the go. Enters Status. Status is a mobile application on Android and iPhone. It allows you to run Decentralized apps, stores your ETH in a wallet and send/receive ETH from another person. It also runs like chatbot.

Installing Status

Mahesh Murthy has an amazing tutorial to setup an Ethereum environment to develop Truffle Dapps on the Ethereum blockchain. You can read it here. Part 1 of the tutorial explains the architecture of the Ethereum platforms and lets you execute a smart contract via a simple web page that runs locally. The blockchain runs locally using testrpc.
