## The second param of listsinceblock

From [issue 8752](https://github.com/bitcoin/bitcoin/issues/8752#issuecomment-247988691)

> The second parameter (target confirmation) is quite strange and should probably be better > documented in the RPC help of listsinceblock (check original comment: #199 (comment))

From the actual docs here is it is:

> target-confirmations:    (numeric, optional) The confirmations required, must be 1 or more

However, that's misleading at best. I've seen at least one project thinking that `target-confirmations` means "filter to only show transactions of n target-confirmations". It's a weird param but I'd document it as

> target-confirmations: (numeric, optional) Return the hash of the block that has target-confirmations of confirmations, for use in a further call to listsinceblock
## Transactions confirmations

Says:

> "confirmations": n,       (numeric) The number of confirmations for the transaction. Available for 'send' and 'receive' category of transactions.

It should also say when it's < 0, it means the transaction conflicted that many blocks ago
## bip125-replaceable

There's an undocumented field of transactions "bip125-replaceable" which I believe has three possibilities "yes" "no" and "unknown"  (under what circumstances it says unknown, should also be documented)

"3. amount            (numeric) Quantity of " + CURRENCY_UNIT + " to move between accounts.\n"
            "4. minconf           (numeric, optional, default=1) Only use funds with at least this many confirmations.\n"
            "5. \"comment\"       (string, optional) An optional comment, stored in the wallet only.\n"
            "\nResult:\n"
            "true|false           (boolean) true if successful.\n"
            "\nExamples:\n"
            "\nMove 0.01 " + CURRENCY_UNIT + " from the default account to the account named tabby\n"
            + HelpExampleCli("move", "\"\" \"tabby\" 0.01") +
            "\nMove 0.01 " + CURRENCY_UNIT + " timotei to akiko with a comment and funds have 6 confirmations\n"
            + HelpExampleCli("move", "\"timotei\" \"akiko\" 0.01 6 \"happy birthday!\"") +
            "\nAs a json rpc call\n"
            + HelpExampleRpc("move", "\"timotei\", \"akiko\", 0.01, 6, \"happy birthday!\"")
        );
