Cryptocurrency ?
• A cryptocurrency (or crypto
currency) is a digital asset designed
to work as a medium of
exchange using cryptography to
secure the transactions and to
control the creation of additional
units of the currency.
• Cryptocurrencies are classified as a
subset of digital currencies and are
also classified as a subset
of alternative currencies and virtual
currencies .

Types of cryptocurrencies
• The first group functions as a currency exclusively.
• It includes Bitcoin and its forks, such as Litecoin or dogecoin. They have no other
functions, except for value transfer.
• The second group has the ability to have distributed computations.
• The main representation of distributed computing is Ethereum and its smart
contracts. It has ability to run small pieces of software on all computers in the
network.
• Privacy coins (anonymity).
• That was the reason for privacy coins to appear on the cryptocurrency scene.
They use different technologies to hide transactions, but the idea is the same
across all of them. Protect the data about senders and receivers.

• The system is peer-to-peer, and transactions
take place between users directly, without an

network nodes and recorded in a
public distributed ledger called a blockchain.

currency. It is powered by technology known as
the blockchain.
