Cryptocurrency transactions are recorded on a decentralized ledger. This ledger is called a blockchain. Every time crypto is bought or sold, the transaction is added to the blockchain — a public database of the transactions, which is available to other crypto holders. Anyone can join and participate in the blockchain, but data on individual transactions — and the people involved with them — are secured using cryptography (the basis for the term cryptocurrency). For each transaction added to the blockchain, there’s a digital validation process to verify it and prevent fraud.
