scantxoutset  (  )

EXPERIMENTAL warning: this call may be removed or changed in future releases.

Scans the unspent transaction output set for entries that match certain output descriptors.
Examples of output descriptors are:
    addr(
)                      Outputs whose scriptPubKey corresponds to the specified address (does not include P2PK)
    raw()                    Outputs whose scriptPubKey equals the specified hex scripts
    combo()                      P2PK, P2PKH, P2WPKH, and P2SH-P2WPKH outputs for the given pubkey
    pkh()                        P2PKH outputs for the given pubkey
    sh(multi(,,,...)) P2SH-multisig outputs for the given threshold and pubkeys

In the above,  either refers to a fixed public key in hexadecimal notation, or to an xpub/xprv optionally followed by one
or more path elements separated by "/", and optionally ending in "/*" (unhardened), or "/*'" or "/*h" (hardened) to specify all
unhardened or hardened child keys.
In the latter case, a range needs to be specified by below if different from 1000.
For more information on output descriptors, see the documentation in the doc/descriptors.md file.

Arguments:
1. "action"                       (string, required) The action to execute
                                      "start" for starting a scan
                                      "abort" for aborting the current scan (returns true when abort was successful)
                                      "status" for progress report (in %) of the current scan
2. "scanobjects"                  (array, required) Array of scan objects
    [                             Every scan object is either a string descriptor or an object:
        "descriptor",             (string, optional) An output descriptor
        {                         (object, optional) An object with output descriptor and metadata
          "desc": "descriptor",   (string, required) An output descriptor
          "range": n,             (numeric, optional) Up to what child index HD chains should be explored (default: 1000)
        },
        ...
    ]

Result:
{
  "unspents": [
    {
    "txid" : "transactionid",     (string) The transaction id
    "vout": n,                    (numeric) the vout value
    "scriptPubKey" : "script",    (string) the script key
    "amount" : x.xxx,             (numeric) The total amount in " + CURRENCY_UNIT + " of the unspent output
    "height" : n,                 (numeric) Height of the unspent transaction output
   }
   ,...], 
 "total_amount" : x.xxx,          (numeric) The total amount of all found unspent outputs in " + CURRENCY_UNIT + "
]
