摘要

Abstract

In order to systematically elucidate the intrinsic logic of blockchain technology enabling online evidence preservation

this paper conducts a systematic review of core literature from 2019 to 2024 through the dual perspectives of smart contracts and consensus mechanisms.Research indicates that smart contracts enable fully automated execution of evidence throughout its lifecycle

effectively mitigating risks of human intervention. Diverse consensus mechanisms are employed to ensure data consistency across distributed nodes

thereby establishing a robust foundation for evidence integrity. Notwithstanding the present challenges

including inadequate legal compliance and performance impediments

the potential of this technology in domains such as judicial evidence preservation will be further actualised through enhanced technical optimisation and interdisciplinary integration.
