摘要
传统的知识共享系统是以个体之间的信任为基础,用户之间的频繁交互和处理交易耗费的人力成本,已经阻碍了知识共享系统的发展。区块链具有可追溯、不可篡改、去中心化等特性,在知识共享领域具有明显优势。在分析区块链关键技术的基础上,提出了一种基于联盟区块链技术的知识共享模型。运用星际文件系统集群保证知识数据存储的可靠性,利用构建的智能合约实现知识共享,并保证知识数据的安全性。最后,基于以太坊在实验室中搭建了共享模型,实验结果表明:该模型能够满足知识共享双边用户的需求,且链上数据具有可溯源、防篡改等特性。
The traditional knowledge sharing system is based on the trust between individuals.The frequent interaction between users and the human cost of transaction processing have hindered the development of knowledge sharing system.Blockchain has the characteristics of traceability,non-tampering,decentralization and so on,which has obvious advantages in the field of knowledge sharing.Based on the analysis of the key technologies of blockchain,this paper proposed a knowledge sharing model based on alliance blockchain technology.The Inter-Planetary File System(IPFS)cluster is utilized to guarantee the reliability of knowledge data storage and the smart contract is utilized to realize knowledge sharing and guarantee the security of knowledge data.Finally,based on Ethereum,a sharing model is built in the laboratory.The experiment shows that the model can meet the needs of bilateral users of knowledge sharing,and the data on the chain has the characteristics of traceability and tamper-proof.
