Blockchain digital forensics:technology and architecture
Issues of limited scene adaptability,inadequate evidence preservation,and low efficiency in traditional digital forensics were addressed by analyzing the feasibility of incorporating decentralized,tamper-resistant blockchain technol-ogy into digital forensic practices.Initially,a phased forensic process was proposed based on a hierarchical architecture for blockchain forensic technology,examining the advancements of blockchain at each stage of evidence acquisition,preservation,and presentation.Subsequently,limitations in existing research were analyzed,and a digital forensic frame-work incorporating comprehensive blockchain involvement was designed by utilizing the distributed advantages of blockchain.This framework integrated evidence information into the on-chain data structure and introduced a comple-mentary graph analysis algorithm to standardize evidence collection across various scenarios.An off-chain distributed da-tabase was employed to achieve scalable,efficient storage,while smart contract templates enhance the reusability of con-tracts for similar forensic transactions.Lastly,potential future directions for the application of blockchain technology in forensic science were explored.
