What is CryptoNote in cryptocurrencies?

CryptoNote in cryptocurrencies is the application protocol upon which all anonymous cryptocurrencies are built. To achieve anonymity, the protocol uses the technology of ring signatures. Using technology makes it possible to hide the identity of the sender, which cannot be revealed from the group. Transactions are sent to one-time addresses, which are generated from random transaction keys and the user's real address. From the outside, multiple transactions sent to the same address will look like they are sent to different addresses that have nothing in common.
