Abstract: Introduction: Blockchain disruptive technology maybe provides solutions to the phenomenon of deepfake and try to solve the problems of image authentication in a post-truth era. Methodology: A bibliographic review search in repositories, digital libraries and databases of physical sciences, computer science and engineering and others of multidisciplinary research. This study is selected sixteen significant articles for analysis. Results: The scientific and academic community poses deepfake's phenomenon as a menace because of its social, political and economic impact. The characteristics of the blockchain, such as traceability, tracking, transparency and trust, make it optimal to authenticate and curb the deepfake phenomenon. Conclusion: Goals with distributed file systems, peer-to-peer networks for sharing and storing, DLTs and blockchain's framework seems satisfactory. Blockchain technical and methodological characteristics, which are its own such as the use of smart contracts, proof-of-authority, hash values and other parameters, must be combined with artificial intelligence detection systems, watermark technology and complicity and commitment of large tech companies and social media platforms, in the authentication and preservation of digital pristine content and detection of its tampering.
