协同卫生保健环境下智能契约的性能和成本评估

区块链作为数据完整性、不可否认性和不同应用的可用性的解决方案而出现。区块链属性也对数据敏感的情景(如医疗保健)有一定的帮助。因此,许多有关在医疗应用情境中采用区块链的研究被提出。然而,很少有人讨论吸引新用户的激励方法,以及如何激励现有终端用户使用系统或应用程序。此外,几乎没有关于区块链代码执行期间的性能的讨论。为了解决这些问题,本文提出了对TokenHealth的初步评估。TokenHealth是利用游戏化和代币激励来实行协作健康的实践监控的一个应用程序。其解决方案是通过利用以太坊区块链中的可靠性来实现智能契约。我们评估了其在测试网络和私有实例中的性能,而初步结果表明,智能合同完成一个全周期的执行时间不到一分钟。此外,我们还讨论了私有情境下的实例和公共以太坊主网络的成本。

原文题目: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.
