Performance and Cost Evaluation of Smart Contracts in Collaborative Health Care Environment
Blockchain emerged as a solution for data integrity, non-repudiation, and availability in different applications, such as in the industry sector. Data sensitive scenarios, such as health care, can also benefit from these blockchain properties. Consequently, different research proposed the adoption of blockchain in health care applications. However, few is discussed about incentive methods to attract new users, as well as to incentive the system or application usage by existing en-users. Also, few are discussed about performance during code executions in blockchains. In order to tackle these issues, this work presents the preliminary evaluation of TokenHealth, an application for collaborative health practice monitoring with gamification and token-based incentives. The proposed solution is implemented using the Ethereum blockchain with Solidity smart contracts programming language. We evaluated the performance of both in
Ropsten test network and in a Private Instance. The preliminary results are for the execution of the smart contracts, with less than a minute for a full cycle of different smart contracts. Also, we present a discussion about costs for using a Private Instance and the Public Ethereum main network.
