Cryptocurrency is a numerable asset that circulates on a blockchain.
The blockchain is then a ledger of accounts and transactions. As if you had an Excel sheet or a big accounting book, with the bank balance of everybody. This sheet or book would keep track of every possible transaction.
Data on a blockchain is added to the database by the addition of a block of information into a chain of existing information.
Each block is cryptographied. Hence the name “blockchain” (a chain of blocks of transactions/operations on a database) and “cryptocurrency” (currency making usage of cryptography).
Cryptocurrencies can be divided into different subcategories: tokens, NFTs, ARTs, EMTs, stablecoins, utility tokens, payment tokens, security tokens, and more.
