语义区块链研究综述

Review on research of semantic blockchain

区块链因具有去中心化、不可窜改、可追溯、集体维护、可编程和安全可信等特点,已应用于金融、物联网、供应链与物流链管理、数字资源版权管理等行业,但因缺乏链间互操作、无法索引查询等问题,极大制约了它的深入应用。语义Web技术和区块链技术融合产生的语义区块链技术,有望解决这些相关问题。为方便研究者系统地了解语义区块链的研究现状和发展趋势,对语义区块链技术进行了综述。首先,分析了区块链对语义Web技术的需求、语义区块链的优点;然后,分析和总结了语义区块链的研究和应用现状,包括区块链本体的设计、区块链数据的语义描述、语义数据的存储、智能合约的语义化、语义区块链的相关应用;最后,对语义区块链的主要研究方向进行了展望。

Because of many key advantages such as decentralization,tamper-resistance,traceability,collective maintenance,programmability and security,blockchain technology has been widely used in finance,Internet of Things,supply chain and logistics chain management,digital resources copyright management and other industries.However,the application of blockchain technology has been greatly restricted due to the lack of interoperability between chains and the lack of efficient queries of blockchain data,and so on.The semantic blockchain technology,the combination of semantic Web technology and blockchain technology-gives hope to solve these problems.In order to facilitate researchers to systematically understand the research status and development trend of semantic blockchain technology,this paper reviewed the semantic blockchain technology.Firstly,this paper analyzed the requirements of blockchain for semantic Web technology and the advantages of semantic blockchain technology,then analyzed and summarized the research and application status of semantic blockchain,including the design of blockchain ontology,the semantic annotation of blockchain data,the storage of semantic data,the semantization of smart contract and the related applications of semantic blockchain.Finally,this paper made a look at the future research directions of semantic blockchain.
