区块链技术存储的电子数据的合法性审查

Legality Review of Electronic Data Stored with Blockchain Technology

区块链技术存储的电子数据与传统电子数据在存储介质以及是否具有阶段性上存在差异,以致于传统电子数据的合法性审查规则无法直接被套用。基于链上生成链上存储的电子数据以及链下生成链上存储的电子数据,按照不同阶段就载体、内容分别进行审查,充分考虑区块链作为载体对电子数据产生的影响。当电子数据存储在区块链上时,采用区块链的合法性审查规则对区块链进行审查,对链下已经进行过合法性审查的电子数据,由于区块链具有不易篡改性,在上链后仅需对上链前后的电子数据的哈希值进行比对即可。另外,对不满足“合规范性”要求但满足“合正当性”要求的电子数据可予以补正,对不满足“合正当性”要求的电子数据则应当予以排除。这样一来,可以使得区块链技术存储的电子数据的合法性审查更为规范和统一。

Because of the differences in storage medium and difficulties in determin the phase of storage between elec⁃tronic data stored with blockchain technology and traditional electronic data,the legality review rules for traditional elec⁃tronic data cannot be directly applied to those stored with blockchain technology.For the electronic data both generated and stored on the chain and those generated off-chain and stored on the chain,thorough consideration is necessary con⁃cerning the influence of the blockchain as a carrier on the electronic data on the basis of respective review of the carrier and the content according to the stage they are in.The rules for the legality review of blockchain should be applied to re⁃view the blockchain when the electronic data are stored on the blockchain,and for the electronic data that have been re⁃viewed for legitimacy off-chain,a hash value comparison of the data before and after they get on the chain is enough because of the immutability of the data on blockchain.In addition,electronic data that do not conform with“the norms”but meet the requirement of“legitimacy”can be corrected,but those that do not meet the requirement of“legitimacy”should be excluded.In this way,the legality review of the of electronic data stored by blockchain technology can be made more standardized and conform with each other.
