gettxoutproof

NOTE: By default, this feature is only occasionally functional. This is the case when the transaction's utxo has an unspent output. Maintaining a transaction index is necessary to ensure that it always functions. You can do this by using the -txindex command line option or by manually specifying the block in which the transaction is contained (by blockhash).
