Research On Blockchain Electronic Evidence Authentication In Civil Litigation

As an important part of the national development strategy,blockchain technology has shown a prosperous development trend with the support of the party and the government in recent years.With the popularization of the concept of "blockchain+",the judicial field has also begun to use the strong anti-tampering advantages presented by the blockchain due to its technical features such as distributed storage and consensus mechanisms to innovate the preservation of electronic evidence.A new form of electronic evidence-blockchain electronic evidence has been produced.However,the field of electronic evidence authentication in my country has not yet formed a complete and unified rule.In addition to the contradiction between the novelty of blockchain technology and the traditional evidence rules,the authentication of blockchain electronic evidence in judicial practice presents a very confusing situation.Leading to the core question of this article,how to authenticate blockchain electronic evidence? The author believes that in order to comply with the trend of widespread application of blockchain technology,the field of evidence law in my country needs to adjust the authentication rules and theoretical innovation to solve the authentication problem of blockchain electronic evidence.Because of its decentralized distributed storage structure,the use of hash value,timestamp and asymmetric encryption technology,blockchain technology has realized the full chain guarantee of the authenticity of the evidence generated by the blockchain and the authenticity of the evidence of the blockchain storage.Sexual stage guarantee.However,based on the contradiction between advanced technology and lagging rules,blockchain electronic evidence is difficult to identify from the original,and whether the blockchain certification of traditional evidence will lead to the loss of evidence independence and the difference between national notarization and technical self-certification Three aspects of the relationship have had an impact on the traditional theory of evidence law.The construction of the certification path of blockchain electronic evidence should still be carried out on the level of legitimacy,relevance and authenticity.The authentication of legality should focus on the legality of the subject and the legality of the method;the authentication of relevance should be considered from the two levels of content association and carrier association;the authentication of authenticity should be based on the blockchain generated evidence and the blockchain storage evidence.The differences between them are carried out in the order of carrier truth,data truth,and content truth.In addition,in order to solve the chaotic situation of blockchain electronic evidence authentication,the following amendments should be made to the authentication rules: establish the principle of case review and technical assistance,and make adaptive changes to the connotation and presumption of the original rules.
