An Analysis of Blockchain Solutions for Digital Evidence Chain of Custody 7th International Congress on Blockchain and Applications Lavin Perrino, Irene Llanos Ferraris, Diego Rafael Informática ISO 27037, CoC, Blockchain 1203 Ciencia de Los Ordenadores 3304 Tecnología de Los Ordenadores Producción Científica Chain of custody (CoC) preservation is essential to ensure the integrity and authenticity of digital evidence in legal and forensic settings. This review article examines how Blockchain-based solutions address the requirements of ISO 27037, which regulates the identification, collection, acquisition and preservation of digital evidence. An initial tax-onomy is also proposed to classify blockchain-based solutions. The analysis reveals significant shortcomings in aspects such as auditability, scala-bility and legal admissibility. Finally, key recommendations are presented to strengthen the integration between Blockchain and ISO 27037 guidelines , fostering more robust solutions aligned with international forensic standards. This work has been partly funded by the NATASHA project (PID2022-142292NB-I00), from the Spanish Ministry of Science, Innovation and Universities. 2025-05-16T08:00:57Z 2025-05-16T08:00:57Z 2025 info:eu-repo/semantics/conferenceObject info:eu-repo/semantics/publishedVersion https://doi.org/10.5281/zenodo.15430154 Blockchain 2025: 7th International Congress on Blockchain and Applications, Lille, France https://uvadoc.uva.es/handle/10324/75760 eng https://www.researchgate.net/publication/391785023_An_Analysis_of_Blockchain_Solutions_for_Digital_Evidence_Chain_of_Custody info:eu-repo/semantics/openAccess application/pdf Springer
