摘要

区块链最近吸引了巨大的兴趣，因为它能够通过不可变的共享分布式账本增强安全性和隐私性。区块链检测完整性违规的能力对于在云平台中提供可靠的数据来源尤为关键。区块链的实际采用将在很大程度上取决于满足性能和安全保证的共识协议。在本文中，我们提出了基于区块链的云溯源共识协议的设计问题。提出了基于区块链的云数据溯源框架。我们发现在此框架内采用工作量证明共识协议存在性能和安全挑战。我们在开发云平台数据来源的权益证明方面提出了独特的设计挑战和机遇。

Consensus protocols for blockchain-based data provenance: Challenges and opportunities

Blockchain has recently attracted tremendous interest due to its ability to enhance security and privacy through a immutable shared distributed ledger. Blockchain's ability to detect integrity violations are particularly key in providing assured data provenance in cloud platform. The practical adoption of blockchain will largely hinge on consensus protocols meeting performance and security guarantees. In this paper, we present the design issues for consensus protocols for blockchain based cloud provenance. We present the blockchain based data provenance framework for cloud. We find that there are performance and security challenges in adopting proof-of-work consensus protocol within this framework. We present unique design challenges and opportunities in developing proof-of-stake for data provenance in cloud platform.
