  1. 3. SMS Certified by Blockchain

3.1 SMS Certified by Blockchain

A SMS certified by Blockchain is a SMS that generates on its delivery a blockchain based certificate of both content and delivery, that can serve as documentary proof in case of legal proceedings.

The blockchain certificate contains within its data blocks the sender’s number, the receiver’s mobile phone number, the message sent in the SMS, the date and time the message was delivered, the digital signature, and a pdf link. This pdf is generated upon the SMS delivery and it contains all the details of the transaction.
