Blockchain Technology Implementation on Simple Microcontroller Based Ballots System

Abstract

Ballots security and reliability is two of the crucial things that makes digital based ballots system not widely implemented. Paper-based ballots have the downsides of environmental impact on making paper. Blockchain has one of the advantages on the security aspect where the blocks are secured using cryptographic protocol that makes it hard to be hacked. This paper will be examining the possibility of ballots implementation using a microcontroller-based ballots system. The microcontroller is used because it is cheap to implement and it has the capability to sign the blockchain transaction. This paper is a proof of concept for a smaller scale ballots system for a small organization with two candidate option. The blockchain network used in this paper is a Ethereum test network provided by Ropsten. The number of testing done is 60 times total for the two candidate. The smaller scale testing proven to be successful with the transaction confirmed successful in etherscan.io.
