How is cryptocurrency tracked and exchanged?

Cryptocurrencies are tracked and exchanged using distributed ledger technology, such as the blockchain. This technology allows for secure and transparent transfer of funds from one user to another without needing to go through a third-party intermediary. The process is facilitated via digital tokens that represent the coins or tokens being traded. These tokens can be stored in digital wallets and exchanged for other digital assets, or for physical currency. Cryptocurrency transactions are usually verified and stored on a public ledger, creating an immutable record of all transactions that have occurred on the network.
