Blockchain technology has evolved as a promising means to transform data management models in many domains including healthcare, agricultural research, tourism domains etc. In the research community, a usable blockchain-based system can allow users to create a proof of ownership and provenance of the research work, share research data without losing control and ownership of it, provide incentives for sharing and give users full transparency and control over who access their data, when and for what purpose. The initial adoption of such blockchain-based systems is necessary for continued use of the services, but their user acceptance behavioral model has not been well investigated in the literature. In this paper, we take the Technology Acceptance Model (TAM) as a foundation and extend the external constructs to uncover how the perceived ease of use, perceived usability, quality of the system and perceived enjoyment influence the intention to use the blockchain-based system. We based our study on user evaluation of a prototype of a blockchain-based research data sharing framework using a TAM validated questionnaire. Our results show that, overall, all the individual constructs of the behavior model significantly influence the intention to use the system while their collective effect is found to be insignificant. The quality of the system and the perceived enjoyment have stronger influence on the perceived usefulness. However, the effect of perceived ease of use on the perceived usefulness is not supported. Finally, we discuss the implications of our findings.

用户对可用的基于区块链的研究数据共享系统的接受度：基于 TAM 的扩展研究

区块链技术已经发展成为在医疗保健、农业研究、旅游领域等许多领域转换数据管理模型的有前途的手段。在研究界，一个可用的基于区块链的系统可以让用户创建所有权和出处的证明。研究工作，在不失去控制权和所有权的情况下共享研究数据，为共享提供激励，并让用户完全透明并控制谁访问他们的数据，何时以及出于什么目的。最初采用这种基于区块链的系统对于继续使用服务是必要的，但它们的用户接受行为模型在文献中没有得到很好的研究。在本文中，我们以技术接受模型（TAM）为基础，扩展外部结构以揭示感知易用性、感知可用性、系统质量和感知享受如何影响使用基于区块链的系统的意图。我们的研究基于使用 TAM 验证问卷对基于区块链的研究数据共享框架原型的用户评估。我们的结果表明，总体而言，行为模型的所有个体结构都会显着影响使用系统的意图，而发现它们的集体效应微不足道。系统质量和感知享受对感知有用性的影响较大。但是，不支持感知易用性对感知有用性的影响。最后，
