Increasing Motivation for Playing Blockchain Games Using Proof-of-Achievement Algorithm

Abstract

Satoshi Nakamoto introduced a peer-to-peer electronic payment system in the paper “Bitcoin: A Peer-to-Peer Electronic Cash System” [12] in 2009. The payment system introduced in this paper (now known as blockchain technology) had a big impact on digital data transfer in a point that using blockchain technology, digital data transfer can be done without having third parties to give trust to the transfer process. In this paper, we focus on one of the key components of the blockchain technology, “consensus algorithm”. We propose a consensus algorithm “Proof-of-Achievement (PoA)” which is an algorithm optimized for blockchain games, focusing on the number of tasks achieved in the game. Using the PoA algorithm, we aim to increase the motivation for playing blockchain games. Through a user study, this paper discusses the effects of the PoA algorithm.
