Blockchain is a sort of public record book that’s created based on computer solutions and automation; it’s shared by many users who transfer information between each other in pairs, from user to user (P2P). The information is not housed in a central database but is classified into different information transactions; these are called ‘block structure,’ by which the sender, receiver, status, and quantity can be determined. It’s a fast, efficient system that establishes a sequence in each transaction so that the information contained is not lost or modified. The most widespread use is associated with cryptocurrencies.
