The cloud has several security and trust issues with the third-party provider. The blockchain-based cloud (BBC) system is an emerging technology that promises safe storage of big data on a cloud. The development of such a system needs requirements engineering (RE) in determining the requirements based on service-level agreements (SLAs). RE can provide a functional process to model and specify a SLA-based smart contract. The RE process for BBC ensures that the resulting SLA specifications are consistent, accurate, complete, verified, and validated. The RE process responds to the many challenges of the BBC and determines a novel direction to provide efficient and quality development of blockchainbased applications.

RE_BBC：基于区块链的云系统中的需求工程：其在服务级别协议规范中的作用


云与第三方提供商存在一些安全和信任问题。基于区块链的云（BBC）系统是一项新兴技术，有望在云上安全存储大数据。这种系统的开发需要需求工程（RE）来根据服务级别协议（SLA）确定需求。 RE 可以提供功能流程来建模和指定基于 SLA 的智能合约。 BBC 的 RE 流程可确保生成的 SLA 规范一致、准确、完整、经过验证和验证。 RE 流程应对了 BBC 的诸多挑战，并确定了一个新的方向，以提供基于区块链的应用程序的高效和高质量的开发。
