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.
