Proof of Game (PoG): A Proof of Work (PoW)’s Extended Consensus Algorithm for Healthcare Application

Abstract

Advancement in blockchain technologies during the past decade has attracted tremendous interests from academia, research community and the industry. A blockchain network is a peer-to-peer, decentralized and immutable distributed ledger system for transactional records. With an increase in the number of blockchain-based applications, it becomes a powerful technology for decentralized data processing and consensus mechanisms based blockchain networks. In this work, a single- and multiplayer bit challenging and incentivized consensus mechanisms for blockchain networks are used in proposing a “proof-of-game (PoG)” protocol for resource variant blockchain networks. Bit verifier PoG is designed to be memory dependent and CPU independent mechanism for time efficiency and resource independence. In results, it is observed that the number of blocks mined using this protocol is proportional to the number of participants associated with blocks. Further, it is observed that the priority of a blockchain increases exponentially with an increase in the number of blocks mined, and the number of blocks mined decreases exponentially with an increase in computational challenge.
