Older versions

For versions below 3.2, a transfer transaction looked like:
|
|
|
|
.. code-block:: js
|
|
|
|
const createTranfer = BigchainDB.Transaction.makeTransferTransaction(
|
|
txCreated,
|
|
metadata, [BigchainDB.Transaction.makeOutput(
|
|
BigchainDB.Transaction.makeEd25519Condition(alice.publicKey))],
|
|
0
|
|
)
|
|
|
|
const signedTransfer = BigchainDB.Transaction.signTransaction(createTranfer,
|
|
keypair.privateKey)
|
|
|
|
|
|
In order to upgrade and do it compatible with the new driver version, this
|
|
transaction should be now:
|
|
|
|
.. code-block:: js
|
|
|
|
const createTranfer = BigchainDB.Transaction.makeTransferTransaction(
|
|
[{ tx: txCreated, output_index: 0 }],
|
|
[BigchainDB.Transaction.makeOutput(
|
|
BigchainDB.Transaction.makeEd25519Condition(alice.publicKey))],
|
|
metaData
|
|
)
|
|
|
|
const signedTransfer = BigchainDB.Transaction.signTransaction(createTranfer,
|
|
keypair.privateKey)
|
|
|
|
|
|
The upgrade allows to create transfer transaction spending outputs that belong
|
|
to different transactions. So for instance is now possible to create a transfer
|
|
transaction spending two outputs from two different create transactions:
|
|
|
|
|
|
.. code-block:: js
|
|
|
|
const createTranfer = BigchainDB.Transaction.makeTransferTransaction(
|
|
[{ tx: txCreated1, output_index: 0 },
|
|
M{ tx: txCreated2, output_index: 0}],
|
|
[BigchainDB.Transaction.makeOutput(
|
|
BigchainDB.Transaction.makeEd25519Condition(alice.publicKey))],
|
|
metaData
|
|
)
|
|
|
|
const signedTransfer = BigchainDB.Transaction.signTransaction(createTranfer,
|
|
keypair.privateKey)
