Listsinceblock

listsinceblock ( "blockhash" target_confirmations include_watchonly include_removed )

Get all transactions in blocks since block [blockhash], or all transactions if omitted.
If "blockhash" is no longer a part of the main chain, transactions from the fork point onward are included.
Additionally, if include_removed is set, transactions affecting the wallet which were removed are returned in the "removed" array.

Arguments:
1. blockhash               (string, optional) If set, the block hash to list transactions since, otherwise list all transactions.
2. target_confirmations    (numeric, optional, default=1) Return the nth block hash from the main chain. e.g. 1 would mean the best block hash. Note: this is not used as a filter, but only affects [lastblock] in the return value
3. include_watchonly       (boolean, optional, default=true for watch-only wallets, otherwise false) Include transactions to watch-only addresses (see 'importaddress')
4. include_removed         (boolean, optional, default=true) Show transactions that were removed due to a reorg in the "removed" array
                           (not guaranteed to work on pruned nodes)

      "amount" : n,                        (numeric) The amount in XEC. This is negative for the 'send' category, and is positive
                                           for all other categories
      "vout" : n,                          (numeric) the vout value

      "confirmations" : n,                 (numeric) The number of confirmations for the transaction. Negative confirmations means the

      "generated" : true|false,            (boolean) Only present if transaction only input is a coinbase one.
      "trusted" : true|false,              (boolean) Only present if we consider transaction to be trusted and so safe to spend from.
      "blockhash" : "hex",                 (string) The block hash containing the transaction.

      "blocktime" : xxx,                   (numeric) The block time expressed in UNIX epoch time.

        "hex",                             (string) The transaction id.

      "time" : xxx,                        (numeric) The transaction time expressed in UNIX epoch time.
      "timereceived" : xxx,                (numeric) The time received expressed in UNIX epoch time.
      "comment" : "str",                   (string) If a comment is associated with the transaction, only present if not empty.
      "abandoned" : true|false,            (boolean) 'true' if the transaction has been abandoned (inputs are respendable). Only available for the 
                                           'send' category of transactions.
      "comment" : "str",                   (string) If a comment is associated with the transaction.
      "label" : "str",                     (string) A comment for the address/transaction, if any

  "removed" : [                            (json array) <structure is the same as "transactions" above, only present if include_removed=true>
                                           Note: transactions that were re-added in the active chain will appear as-is in this array, and may thus have a positive confirmation count.
    ...
  ],
  "lastblock" : "hex"                      (string) The hash of the block (target_confirmations-1) from the best block on the main chain. This is typically used to feed back into listsinceblock the next time you call it. So you would generally use a target_confirmations of say 6, so you will be continually re-notified of transactions until they've reached 6 confirmations plus any new ones
