Mapping of Tourism Destinations by GIS-Blockchain RPCA based on PNPOLY Algorithm

This study aims to mapping the halal tourism destination using GIS blockchain based on PNPOLY. The Ripple Protocol Consensus Algorithm (RPCA) is used to develop the blockchain. In this experiment, the data from the surveyor are input using an application that connects to the transaction set node. Then, the transaction set nodes to send the data to the transaction proposal node. The transaction proposal nodes would then distribute data to each validation data of the connected nodes to execute smart contracts with the PNPOLY method because this method used to perform smart contracts in supervising the performance of surveyors in conducting data inputs and coordinates of tourist assets according to real conditions in the field. If the smart contract process is successful with a maximum error tolerance of 20% in other transaction proposals, then this node records the new chain to the general ledger. The result of this process is a mapping of the halal tourism destination in city of Surabaya.
