| 中文摘要: |
| 从区块链的技术层面及应用层面分析其特征，并给出区块链的分类.挖掘区块链的设计需求，针对区块链的一致性和可扩展性的应用需求进行深入分析.对区块链的应用系统开发方法及区块链建模进行研究，提出了账户区块链（account blockchain，简称ABC）和交易区块链（trading blockchain，简称TBC）的双链设计模型.对智能合约进行深入剖析，提出了链上代码并行执行模型应用原则.最后，对区块链应用技术进行总结和展望. |
| 英文摘要: |
| This paper presents a blockchain definition independent of any digital currency, and describes its characteristics including consensus protocols, design patterns, scalability, databases, and chaincode. The paper then presents a permissioned blockchain, called Beihangchain, with its unique consensus algorithms, interfaces, and design. It also proposes ABC (account blockchain) and TBC (trading blockchain), to be used for a variety of applications including copyright protection and digital payment. Finally, this paper analyzes chaincode requirements and provides guidelines for effective chaincode. |
