Method: POST gettxoutproof

POST

gettxoutproof

Returns a hex-encoded proof that id 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).

Parameters

txids - json array, required

A json array of txids to filter

blockhash - string, optional

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