The cryptocurrency operates as open source software on a peer-to-peer model (transactions take place directly between the payer and payee). This means that no trusted intermediary such a bank or PayPal is required to verify the details of the sender and receiver. Rather, the transactions are verified by nodes (the network of computers/users spread globally) and recorded in an open ledger referred as blockchain.
