针对数据库访问控制中存在的问题，提出将区块链技术应用于数据库访问控制的思想。从区块链层次结构、访问控制过程的逻辑层次结构、访问控制的实现原理、访问控制的共识认证原理以及访问控制区块链体系的构建机制几个方面设计了基于区块链的数据库访问控制实现机制，对基于区块链的数据库访问控制体系的性能进行评价。为区块链应用于数据库访问控制提供了完整的架构，通过对访问者身份、访问权限及访问行为强化认证与监管，有效地提高了数据库访问控制的能力。

A purely peer-to-peer version of electronic cash would allow online
payments to be sent directly from one party to another without going through a
financial institution. Digital signatures provide part of the solution, but the main
benefits are lost if a trusted third party is still required to prevent double-spending.
We propose a solution to the double-spending problem using a peer-to-peer network.
The network timestamps transactions by hashing them into an ongoing chain of
hash-based proof-of
