Output recognition ================== The module provides means to obtain output information from transactions as well as recognize and decrypt those destined to user's own wallet. That functionality is a part of ``Transaction.outputs(wallet=None)`` method which may take a wallet as optional keyword, which will make it analyze outputs against all wallet's addresses. The wallet **must have the secret view key** while secret spend key is not required (which means a view-only wallet is enough). .. note:: Be aware that ed25519 cryptography used there is written in pure Python. Don't expect high efficiency there. If you plan a massive analysis of transactions, please check if using Monero source code wouldn't be better for you. .. note:: Please make sure the wallet you provide has all existing subaddresses generated. If you run another copy of the wallet and use subaddresses, the wallet you pass to ``.outputs()`` **must have the same or bigger set of subaddressses present**. For those missing from the wallet, no recognition will happen. Output data ----------- The method will return a set of ``Output`` objects. Each of them contains the following attributes: * ``stealth_address`` — the stealth address of the output as hexadecimal string, * ``amount`` — the amount of the output, ``None`` if unknown, * ``index`` — the index of the output, * ``transaction`` — the ``Transaction`` the output is a part of, * ``payment`` — a ``Payment`` object if the output is destined to provided wallet, otherwise ``None``, An example usage: .. code-block:: python In [1]: from monero.daemon import Daemon In [2]: from monero.wallet import Wallet In [3]: daemon = Daemon(port=28081) In [4]: tx = daemon.transactions("f79a10256859058b3961254a35a97a3d4d5d40e080c6275a3f9779acde73ca8d")[0] In [5]: wallet = Wallet(port=28088) In [6]: outs = tx.outputs(wallet=wallet) In [7]: outs[0].payment.local_address Out [7]: 76Qt2xMZ3m7b2tagubEgkvG81pwf9P3JYdxR65H2BEv8c79A9pCBTacEFv87tfdcqXRemBsZLFVGHTWbqBpkoBJENBoJJS9 In [8]: outs[0].payment.amount Out [8]: Decimal('4.000000000000')
