Cryptospatial blockchain sharia hotel based on practical Byzantine fault tolerance

Abstract

This research develops an application based on android that uses four interconnected nodes in a network with the Practical Byzantine fault tolerance (PBFT) blockchain method to value object geospatial retrieval. First, this application uses two types of users, general users and surveyors. Second, a surveyor location is validated within a radius of fifty meters from the central point of assets location using midpoint circle validation. Third, PBFT is used to access and validate and guarantee consistency by data using JSON-DIFF algorithm.
