The data model: blocks, transactions, transfers, and outputs

Overview

This section introduces the data model used in monero-ts. Refer to the API specification or JSDocs for more information.


Blocks have transactions which can have incoming transfers, an outgoing transfer, and outputs.

JSON

The following JSON demonstrates the data model as a serialized transaction which sends funds to two accounts in the same wallet, so it has both an outgoing transfer and incoming transfers.

The top level is a block which contains transactions.

Transactions can have incoming transfers and an outgoing transfer.

The outgoing transfer may have destination addresses and amounts (note: this information is only saved locally with the wallet file and is not stored on the blockchain).

Transactions can also have outputs received by the wallet.
