Prototype of Blockchain in Dental care service application based on Hyperledger Composer in Hyperledger Fabric framework

摘要

Most enterprise blockchain applications rely on real world trust relationship such as the business in financial institutions, entertainment industry, supply chain industry, transportation, education, healthcare services, etc. Hyperledger aims to advance blockchain technology that confederate in the cross-industry to open standard platform for distributed ledgers, which can transform the way business transactions are controlled globally. As we know currently the model of blockchain have permissionless blockchain and permissioned blockchain, which the permissionless blockchain such as Bitcoin cryptocurrency that anyone can operate a node and participate through spending CPU cycle and demonstrating a proof of work. On the other hand, permissioned blockchain model control who participates in validation and in the protocol. More over these nodes typically have established identities and form a consortium. Therefore, to make the innovation application that need the authority and permission for submitting the transaction we will select the hyperledger fabric framework to develop our project. Hence this paper will focus to study to develop a prototype of healthcare service application in dental clinic service. In order to keep records transactions that are accessible and controlled the authority by participants which it has a transaction id number that generate by hash number mechanism running by hyperledger composer. This application will create a trust relationship wherein the goal is to set up a set of participants in an ecosystem that it needed in health care service in the field of sharing the medical equipment and transaction that can save a variety of costs and make an interoperability process in the clinics.
