区块链技术已经从加密货币的不可变交易账本发展成为用于构建分布式可靠应用程序的可编程交互环境。尽管区块链技术已被用来解决各种挑战，但据我们所知，以前的工作都没有专注于使用区块链开发安全且不可变的科学数据来源管理框架来自动验证来源记录。在这项工作中，我们利用区块链作为平台来促进值得信赖的数据来源收集、验证和管理。开发的系统利用智能合约和开放起源模型（OPM）来记录不可变的数据轨迹。我们表明，我们提出的框架可以安全地捕获和验证来源数据，只要大多数参与者是诚实的，就可以防止对捕获的数据进行任何恶意修改。
Blockchain technology has evolved from being an immutable ledger of transactions for cryptocurrencies to a programmable interactive environment for building distributed reliable applications. Although the blockchain technology has been used to address various challenges, to our knowledge none of the previous work focused on using Blockchain to develop a secure and immutable scientific data provenance management framework that automatically verifies the provenance records. In this work, we leverage Blockchain as a platform to facilitate trustworthy data provenance collection, verification, and management. The developed system utilizes smart contracts and open provenance model (OPM) to record immutable data trails. We show that our proposed framework can securely capture and validate provenance data that prevents any malicious modification to the captured data as long as the majority of the participants are honest.
