Cryptocurrency is a specific type of digital money. Its operation is facilitated by an automated payment system without a single central authority. Blockchain and distributed ledger technology are the main technical means of implementing cryptocurrencies.
Cryptocurrency is stored in special wallets that contain individual identifiers and transaction histories of specific network "participants." A user can have as many wallets as they like, which, in the case of cryptocurrencies, are confidential. It is impossible to determine who is behind a specific identifier or who uses it as a means of payment. Wallets are protected by cryptographic encryption. Transactions are also cryptographically secured, which prevents interception or falsification by malicious actors.
