gettxoutproof ["txid",...] ( "blockhash" )

Returns a hex-encoded proof that “txid” was included in a block.

NOTE: By default this function only works sometimes. This is when there is an unspent output in the utxo for this transaction. To make it always work, you need to maintain a transaction index, using the -txindex command line option or specify the block in which the transaction is included manually (by blockhash).

Argument #1 - txids

Type: json array, required

A json array of txids to filter

  "txid",    (string) A transaction hash

Argument #2 - blockhash

Type: string, optional

If specified, looks for txid in the block with this hash


Name Type Description
data string A string that is a serialized, hex-encoded data for the proof.
