Certainly the adequacy of digital technologies contemplates the use and adequacy of the blockchain, since it is very important for the oil industries that their data is stored in a system where the information can remain intact forever, even payments with cryptocurrencies through the blockchain is also contemplated for payment for barrels of oil and its derivatives.

Thank you friend for reading and making a comment where you share your impressions. Regards
