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).
Type: json array, required
