#USCryptoReserve under the pseudonym Satoshi Nakamoto; it is unknown whether it was developed by a single person or by a group of specialists. Its operation is based on the generation of a unique digital file that, through cryptography, guarantees its authenticity – hence the term cryptocurrency – in addition to a global database – called blockchain – that transparently shows how and when each of these files was created. Likewise, the algorithm that generates it is designed so that there is a unique and limited amount of bitcoins, and that after a certain period, fewer and fewer can be created – this process is called ‘halving’ – until reaching its final amount of 21 million, which is projected to be reached in the year 2144.
