ICP Transactions
On the Internet Computer blockchain, the information about ICP tokens is maintained in the Ledger canister, a component of the Network Nervous System. The Ledger canister maintains a mapping between account identifiers and ICP token amounts. The Ledger provides an API that allows the principal, e.g. a user or a canister, who controls an account to transfer ICP tokens to any other account. All transfers are recorded as transactions in a ledger of transactions. The ledger also records minting and burning of ICP tokens.
