Didn't know you could add the line # to such source links - nice!

But just below that is the following:

Code:

if (fAllowFree)
{
if (nBlockSize == 1)
{
// Transactions under 10K are free
// (about 4500 BTC if made of 50 BTC inputs)
if (nBytes < 10000)
nMinFee = 0;
}
else
{
// Free transaction area
if (nNewBlockSize < 27000)
nMinFee = 0;
}
}

And the call you showed to this function sets fAllowFree to true.

Read the code, not some wiki.

Priority is only used if the minimum fee is zero. If there is a dust output, the minimum fee calculated by GetMinFee() is not zero.

You have no link to the code, I can't take your word for a snippet, but I am still 99.999999% sure that dust, that is aged can be sent without a fee, if aged. I coded a faucet, I kinda know what I am talking about in that sense, and the wiki is also pretty reliable.

Not if aged, if aged long enough no fees are force, or even needed. This is prevent spamming the blockchain.

No, CTxMemPool::accept() won't accept such a transaction into the mempool at all:

Code:

int64 txMinFee = tx.GetMinFee(1000, true, GMF_RELAY);
if (fLimitFree && nFees < txMinFee)
    return error("CTxMemPool::accept() : not enough fees %s, %"PRI64d" < %"PRI64d,
                        hash.ToString().c_str(),
                        nFees, txMinFee);

and CTransaction::GetMinFee():

Code:

// To limit dust spam, require MIN_TX_FEE/MIN_RELAY_TX_FEE if any output is less than 0.01
if (nMinFee < nBaseFee)
{
    BOOST_FOREACH(const CTxOut& txout, vout)
        if (txout.nValue < CENT)
            nMinFee = nBaseFee;
}

Age has nothing to do with it.

That's not it - the default fee rules force fee payment on dust outputs.

If the output is old enough then no tx fee is necessary (even if it is only 1 Satoshi).

They send it once a day, probably other external funds that are aged.

Well...how the fuck are all these other PTC/Faucets doing it without running a 10x loss on what they send!?

I dunno. Maybe they are too? Where an example of one of their transactions for us to look at?

So... No solution as of yet has been proposed and the 1000% fee is .... not workable. I want to send thousands of people BTC! RIGHT NAO. Anyone know of a working method to have a even remotely reasonable tx fee ?

The Bitcoin blockchain is not a microtransactions payment system.

And to quote myself:

Quote from: CIYAM on March 22, 2013, 01:45:19 AM

oic - am guessing the best way to avoid fees with a faucet would be to have all its UTXOs being the exact amount as the outputs you wish to send and then just make sure that the wallet is "old" enough so that no tx fees are required at all (and replace wallets with new ones as they get exhausted).

(although that might mean having to put a month delay between now and your next payouts to age the coins enough)

Note that using uniform payment UTXOs (i.e. no change needed) will help to avoid getting even newer dust UTXO's every time you make a payout.

Ok your running a faucet, since your transactions are very small probably I am guessing, this is how the network protects it's self, so having no fees will never happen, you can set the fee to zero it will or may never confirm, and low fees aren't possible, unless you age the coins for a long time. So right now the best way, is the way your doing it.

lol! Max debug console input is 32,767 characters

Also got this error...

Quote

Error: value is type int, expected obj

Something tells me this has something to do with it

Code:

amounts are double-precision floating point numbers (code -1)

UPDATE:

After a JSON Error, a few Invalid BitCoin Address errors, and a insufficient funds error I finally got it to sendmany

But....

980% the amount transferred just to send it!

Code:

BTC Transacted: 0.001422 BTC
Transaction fee: -0.014 BTC
Net amount: -0.015422 BTC
Transaction ID: da3d8921166b8509fb7777b3f8bcb32805014e42d1e667fc9d2769d7d943b4f9

That was just a test really, 4 days worth of 'Single BitHitters' - 711 Addresses Paid

also........ Unless There is a way I can pass more data to the Debug Console I cant do much larger tx then that.... 711 is only 49 addresses short of my source list I was using...

This....might actually be a HIGHER fee then what sending normally with the GUI was ?

I think I can make a script that will create such a request..

If your using php it is really easy get all address and amount put them into an array, then run json_encode on the array and then pass it to the bitcoind

... is there a client that can do sendmany ?

..i found this

Code:

sendmany {address:amount,...} [minconf=1] [comment]

That would be a very very long command thou...

I generally send to about 2000+ addresses at once.

Yes this is the correct way to do it with 2000+ addresses as long as you have the funds it will work.

Code:

    y = 0
    For x = 0 To UBound(BTCAd)
        SendMany = SendMany & "," & Chr(34) & BTCAd(y) & Chr(34) & ":" & Val(Text1.Text)
        y = y + 1
        Sleep (1)
    Next x
SendMany = "sendmany BitHits.info '{" & SendMany & "}' 0"
Text2.Text = SendMany

default bitcoind with commandline or rpc
or you use blockchain.info
