Redactable blockchain scheme with controllable and accountable editing
摘要
Abstract
Many existing blockchain application schemes emphasize block editability to address potential errors.A secure and effective redactable blockchain scheme requires that on-chain data remain editable while it strictly controls editing permissions.To address these problems,this paper firstly proposed an edit request control strategy to address the issue of excessive editing in blockchain editing.This strategy used smart contracts to record the editing status of all nodes and blocks,enabling effective control over related editing requests.It then designed a representative node mechanism for large-scale blockchain environ-ments,selecting representative nodes based on a reputation evaluation strategy driven by their editing behavior,which enhan-ced the efficiency of trapdoor recovery under decentralized trapdoor management.Finally,it established a trusted chameleon-based random number generation mechanism to strictly restrict the editing content handled by representative nodes,achieving fine-grained control over editing permissions.Comparative analysis and experimental results show that the scheme achieves de-centralized trapdoor management and block editing while ensuring system security and efficiency.The scheme exhibits higher stability and controllability in complex editing environments.关键词
