  "size" : n,           (numeric) The serialized transaction size
  "vsize" : n,          (numeric) The virtual transaction size (differs 
                                  from size for witness transactions)
  "version" : n,        (numeric) The version
  "locktime" : ttt,     (numeric) The lock time
  "vin" : [             (array of json objects)
     {
       "txid": "id",    (string) The transaction id
       "vout": n,       (numeric)
       "scriptSig": {   (json object) The script
         "asm": "asm",  (string) asm
         "hex": "hex"   (string) hex
       },
       "sequence": n    (numeric) The script sequence number
       "txinwitness": ["hex", ...] (array of string) hex-encoded witness 
                                  data (if any)
     }
     ,...
  ],
  "vout" : [            (array of json objects)
     {
       "value" : x.xxx,     (numeric) The value in BTC
       "n" : n,             (numeric) index
       "scriptPubKey" : {   (json object)
         "asm" : "asm",     (string) the asm
         "hex" : "hex",     (string) the hex
         "reqSigs" : n,     (numeric) The required sigs
         "type" : "pubkeyhash",  (string) The type, eg 'pubkeyhash'

         ]
       }
     }
     ,...
  ],
  "blockhash" : "hash",   (string) the block hash
  "confirmations" : n,    (numeric) The confirmations
  "time" : ttt,           (numeric) The transaction time in seconds since 
                                    (Jan 1 1970 GMT)
  "blocktime" : ttt       (numeric) The block time in seconds since (Jan 1 
                                    1970 GMT)
}
