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

 * 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).
