區塊鏈作為數據完整性、不可否認性和不同應用的可用性的解決方案而出現。區塊鏈屬性也對數據敏感的情景(如醫療保健)有一定的幫助。因此，許多有關在醫療應用情境中採用區塊鏈的研究被提出。然而，很少有人討論吸引新用戶的激勵方法，以及如何激勵現有終端用戶使用系統或應用程式。此外，幾乎沒有關於區塊鏈程式碼執行期間的性能的討論。為了解決這些問題，本文提出了對TokenHealth的初步評估。TokenHealth是利用遊戲化和代幣激勵來實行協作健康的實踐監控的一個應用程式。其解決方案是通過利用以太坊區塊鏈中的可靠性來實現智慧契約。我們評估了其在測試網路和私有實例中的性能，而初步結果表明，智慧合約完成一個全周期的執行時間不到一分鐘。此外，我們還討論了私有情境下的實例和公共以太坊主網路的成本。
原文題目：Performance and Cost Evaluation of Smart Contracts in Collaborative Health Care Environments
原文：Blockchain emerged as a solution for data integrity, non-repudiation, and availability in different applications. 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 appli- cations. However, few are discussed about incentive methods to attract new users, as well as to motivate the system or application usage by existing end-users. Also, little is discussed about performance during code execution 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 through smart contracts using Solidity in the Ethereum blockchain. We evaluated the performance of both in Ropsten test network and in a Private instance. The preliminary results show that the execution of smart contracts takes 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.
