Cryptocurrency is a new world

Its history:

In 1977, the RSA algorithm appeared. It was invented by Leonard Adelman, Adi Shamir, and Ronald Rivest at the Massachusetts Institute of Technology, which was announced at the time and a paper on its invention was published. In its abbreviation, it consists of 3 letters, which are the first letters of their names.

In 1993, mathematician David Chumm invented what is said to be the first electronic encrypted currency, which was based on cryptography.

In 1996, E-gold was launched, which is the first site for exchanging and trading gold, which requires opening an account and using it to buy and sell gold.

.

The block chain was defined in the book (The Block Chain Revolution) as an electronic ledger, used to record financial and economic transactions, for everything that has value, so that it is recorded and encrypted with each user in the form of a block, and then all these blocks are linked to each other to form a chain. Of the blocks, they are distributed and saved on the computers of all users around the world, which makes the process of hacking or tampering with them practically impossible, because, as we mentioned, they are stored with the users, which makes changing or erasing them not possible except by controlling the computers of all users around the world, which is something that is not possible. It is currently achievable.
