摘　　要：针对传统协同开发系统普遍采用"中心化"存储架构带来的单点故障、数据不可信、故障难以追责等安全问题,以及传统协同办公系统仅支持单一企业内部办公的问题,本文借助超级账本Fabric区块链技术以及业务流程管理和服务组合技术实现了一款基于Fabric区块链的智能合约协同开发系统.系统架构中首先结合传统中心化存储技术和区块链去中心化存储技术,通过将系统核心业务数据信息存储在区块链分布式账本中而把业务流程管理等不重要的数据存储在传统数据库中解决了"中心化"存储管理带来的安全信任问题.其次系统通过结合超级账本联盟链技术提供的企业联盟的特点使得系统可以应用于企业联盟办公中,解决了单一办公的问题.Aiming at the security problems such as single point of failure,data untrustworthiness,failure untraceability caused by centralized storage architecture and the problem that traditional collaborative office system only supports single enterprise internal office,this paper uses hyperledger fabric blockchain technology,business process management technology and service combination technology to implement a smart contract collaborative development system based on fabric blockchain.Firstly,the system architecture combines the traditional centralized storage technology and the blockchain decentralized storage technology.By storing the core business data information in the blockchain distributed ledger and the unimportant data such as business process management in the traditional database,the problem of security and trust brought by centralized storage management is solved.Finally,by combining the characteristics of enterprise alliance provided by hyperledger fabric blockchain technology,the system can be applied to enterprise alliance office,and solve the problem of single office.
