摘要
大数据的流通是创造数据价值的关键一环,然而目前数据流通面临着诸多问题。区块链是一种分布式账本技术,具有去中心化和不可篡改特性,可以解决数据流通过程中的一些痛点问题。介绍了区块链技术的特性,阐述了利用区块链改造授权存证环节、进行数据溯源和实现智能合约的主要思路,梳理了实现数据流通的整体架构。在此基础上,给出了国外利用区块链进行数据流通的应用实例,并介绍了一些其他的数据流通新技术。
Circulation of big data is a key link in the value creation of data, but there are numerous problems to be solved. Blockchain is a distributed ledger technology, which can be applied in data circulation by its decentralizing and immutable property. The main idea of authorized deposit certificate, data traceability and smart contract using blockchain was discussed, and the overall architecture of data circulation by blockchain was proposed. Finally, some applications and other data security solutions were introduced.
