Designing a voting DApp

Decentralized voting on a blockchain has many perks. It is extremely hard to tamper with once a candidate is voted for. In this section, we try to design a simple voting DApp using both the private blockchain (also known as a private testnet) and remix platform that was introduced in Chapter 3, Hello World of Smart Contracts.

At this point, it will be good to recap the difference between an EthereumJS-based testrpc and Geth-based testnet from Chapter 2, Grokking Ethereum . A test RPC is a third-party client implementation used for testing. It is basically a Node.js-based Ethereum client. It simulates a full client. Whereas Geth-based testnet is an official full client implementation in the Go language, having a command-line interface, which can be used to connect to the real blockchain or on public testnet blockchains, such as Ropsten, or on a private testnet blockchain like ours.

The voting DApp we will develop has three basic functions:

  • It initializes a list of candidates...
