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). | |||||
Arguments: | |||||
1. txids (json array, required) A json array of txids to filter | |||||
[ | |||||
"txid", (string) A transaction hash | |||||
... | |||||
] | |||||
2. blockhash (string, optional) If specified, looks for txid in the block with this hash | |||||
Result: | |||||
"data" (string) A string that is a serialized, hex-encoded data for the proof. | |||||
