The emerging technology called blockchain promises to be part of document certification processes, transactions and digital communications. Therefore, it has been used successfully as part of digital currency schemes.
Now we mention its possibilities to be applied in various situations of forensic interest.
In addition to its usefulness in different processes, several applications are proposed for this emerging technology. For example, being a complement in medical records, assistants in notary services, verifiers in tax collection, as well as the processing of smart contracts. These are all cases of interest to lawyers, but in the forensic context it can also be applied.

The primary objective being the most efficient integration of the investigation files, keeping digital evidence available and preserving the chain of custody. Preventing the loss, falsification or illegibility of information, privacy violations, as well as data duplication. The incorporation of this technology in automobiles to store digital information and then be able to use it in cases of traffic accidents, creating a blockchain before and after the event, the vehicles involved would support the forensic investigation. Similarly, the incorporation of cell phone information into a forensic blockchain could be used as evidence in criminal cases. Forensic Preparation proposes that digital evidence is collected and secured in advance and the data that is collected can be used as material for the analysis of security incidents and also as legal evidence.
For the reasons stated above, it is confirmed that this blockchain technology will change the way many legal processes are carried out.
