gettxoutproof (0.17.99 RPC)

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"

    [

      "txid"

2. "blockhash"

Result

"data"
