+blockchain.transaction.get_merkle_witness
+=========================================
+
+Witness-SPV. Proves that a transaction with a given wtxid was mined in a particular block.
+
+**Signature**
+
+  .. function:: blockchain.transaction.get_merkle_witness(txid, height=None, cb=false)
+  .. versionadded:: 1.6
+
+  *txid*
+
+    The txid (NOT wtxid) as a hexadecimal string.
+
+  *height*
+
+    Optionally, the height at which it was confirmed, an integer.
+    Clients are encouraged to provide this field when they can, to reduce server load.
+
+  *cb*
+
+    A boolean.
+    If set to :const:`true`, the result MUST also include the *cb_tx* and *cb_proof* fields.
+    If set to :const:`false`, those fields are omitted.
+
+**Result**
+
+  A dictionary with the following keys:
+
+  * *wtxid*
+
+    The wtxid of the mined transaction, as a hexadecimal string.
+
+  * *block_height*
+
+    The height of the block the transaction was confirmed in, an integer.
+
+  * *block_hash*
+
+    The hash of the block the transaction was confirmed in, as a hexadecimal string.
+
+  * *pos*
+
+    The 0-based index of the position of the transaction in the
+    ordered list of transactions in the block, an integer.
+
+  * *cb_tx*
+
+    The raw coinbase transaction from the block, as a hexadecimal string.
+
+  * *cb_proof*
+
+    Merkle branch to prove `cb_tx` (against block header merkle root).
+    A list of transaction hashes the current hash is paired with,
+    recursively, in order to trace up to obtain merkle root of the
+    block (in header), deepest pairing first.
+
+  * *wmerkle*
+
+    A witness merkle branch to prove `wtxid` (against `cb_tx`).
+    A list of hashes the current hash is paired with,
+    recursively, in order to trace up to obtain `witness root hash`
+    (committed to in the coinbase), deepest pairing first.
