Guide to Developing an Ethereum Decentralized Voting Application

The blockchain systems continuously grow and evolve, and a great way to use the technology is through decentralized applications known as dApps. CryptoKitties is an excellent example of dApps as it successfully combines the concepts of collectible cats and blockchain. It is a highly popular game and just one model out of the many opportunities that are possible. 

Why Do We Make a Decentralized Voting App?

A decentralized application that uses blockchain allows us to carry out specific actions such as transfer of money without any third party; however, trusted it might be. Some of the best and popular dApps have a real-world use-case that displays the essential Blockchain nuances. It is understood that the voting app may not be the best choice for consumers. Still, it is necessary to keep in mind that the main concepts that are handled by Blockchains like audibility, accessibility, security, and transparency are also the same problems that continue to hinder present democratic elections. 

But what makes dApps so unique? Blockchain keeps an enduring record of all the transactions or votes, as in this case, all votes can be easily traced back to the location of incidence with no chance of getting the voter’s identity being revealed. Since every node in the network verifies each vote, the votes that have been cast in the past can never be altered, and the present votes cannot be hacked. The system is fully secure as it would require an attacker to have control of at least 51% nodes to bring about a change in results. 

Designing a Voting dApp

The concept of decentralized voting on a blockchain has many perks. It is tough to tamper with the results once the candidate has given his/her votes. It is possible to design a simple voting dApp using a private blockchain and a remix platform. 

Core Components of the Ethereum

If you are not new to Blockchain and Ethereum’s concepts, you should understand the core components of Ethereum. 

1. Smart Contracts are back-end storage. Solidity is actually a Smart Contract language that is a bunch of data and code that occupies a particular address of the Ethereum blockchain. It is similar to Object-Oriented Programming that includes state variables and functions.
2. The Ethereum Virtual Machine or EVM manages the computation of the full Ethereum Network. The Ethereum Virtual Machine can be conceptualized as a huge decentralized machine with the addresses that can change data and execute code.
3. Web3.js is a Javascript API that facilitates interaction with blockchain, like making transactions. Any communication with the Ethereum Clients is made abstract by the API, allowing the developers to concentrate fully on the application content. One should have a web3 instance embedded in the browser to achieve this. 
4. The Mist Wallet is a user-interface (UI) based software that is used to connect to the Ethereum blockchain. It is dependent on the Geth client to perform all the operations seamlessly. The software can be used to create accounts, design contracts, transfer across the accounts, and view the transaction details.

Conclusion

Building applications on Ethereum is easy and similar to a regular application taking a back-end service. The hardest part is, of course, writing a robust and smart contract. One should have a proper understanding and core knowledge of decentralized applications and Ethereum, and this will kick-start an interest in developing them.
