This comprehensive review paper examines the integration of "Smart Contracts for Smart Forensics," focusing on the synergy between digital forensics and blockchain technology. In legal scenarios, digital forensics includes collecting, preserving, analyzing, and interpreting digital evidence. Blockchain technology, renowned for its distributed and tamper-resistant ledger, offers promise for enhancing the security and integrity of forensic procedures. The amount of digital evidence, however, presents difficulties, as does the requirement for maintaining a balance between privacy and traceability. Ensuring accurate provenance records is crucial for evidence credibility and integrity in digital forensics. Blockchains offer properties to address these needs, but tailored designs are necessary for efficient provenance extraction. By exploring the practical applications of smart contracts in forensic procedures, the paper offers valuable insights into enhancing security and efficiency in digital forensic investigations. Through these discussions, the paper aims to contribute significantly to the advancement of forensic practices, specifically emphasizing the transformative potential of smart contracts in ensuring integrity and trustworthiness.
