Some things to consider:

Transaction fees would also go to the pool, right?

How about the "I find a solution but don't post it" attack, aka. "withholding winning shares"? As miners might have to be adapted for this pooling scheme anyways, please also implement "oblivious shares"!

Can the pool require it's miners to always include some special transactions (for free), like payouts?

It just depends on how much you sell your BTC for, if that's a bad or a good thing.

If 1 Bitcent would now be worth 100 USD, you would earn much more than at the ~17USD/BTC before.

Fee? Transaction fees mined belong to...? Proportional means "1 share out of 100 earns 1% of BTC mined, regardless of when it has been submitted" - right?

There would be no better way to finally eliminate pool hopping than releasing an easy-to-use open source pool hopping software, so every pool that still uses proportional payout will be abused like there's no tomorrow.

I can give you tipps on an easy possible implementation if you want to, you would just need twisted (a python framework), python and a internet connection... Also probably a database to store the one value that cannot easily be extracted live: Current total pool hash rates (though it might be very well possible to calculate a good enough estimated number on larger pools with >100 blocks solved)

Do you even know what "ASIC" stands for?! Probably not, or you would know, why what you just said is completely stupid.

About FPGAs: They are maybe good at MH/W performance, performance per chip wise they quite honestly seem to suck though.

0.02 Bitcoin on "NEVER".

Use google or the search function here, you already know the search term "pool hopping"...

We really don't need another thread coming up with this, can't you just start a "I BOUGHT 5 6990 GPUS, WHERE'S MY FREE MONEY?!" thread like every other kiddie here?

Because (like with every difficulty increase) the graphs average over a few blocks/hours/days and thus overshoot at the beginning.

This could be fixed by calculating block-to-block hashrate and after that smoothing things out instead of calculating 100 blocks-to-100 blocks hashrates while assuming the same difficulty for them, but that would be more computationally intense probably.

Biggest problem right there:
Such a client would be of NO use to generate BTC, meaning it needs to be willingly installed. It's not that easy to convince people to do this!

Also it is quite hard to bruteforce a wallet, so this again could lead to "some" problems (like "the sun expanding to the surface to the earth sooner"-type problems!).

Aaaand there is the small (but not impossible) chance, that the wallet you crack as a combined effort is your own!

ASICs won't ever be cheap (as they have to be custom made), FPGAs will only start to pay off if the difficulty stays fairly constant over half a year or so OR if you can get them for free (more or less).


As the most exiting thing for most people seems to be either:
"I can produce money with my computer!!!11"
or
"The exchange rate went up like OVER 9000%!!!!11"

There seems to be demand for both buying and producing BTC at the moment.
Buying actually is REALLY hard, especially if you want to buy fast, this is why a lot of people seem to rather start mining.


Anyways, I think it will still take some time until the hashrate stabilizes, so the biggest hashrate-burst as fast as possible currently wins. This means GPUs won't even be beatable by the cheapest available FPGAs in the near future income wise.

Shall I put up a sell order for 999999999999999999 shares?!

Anyone can sell as many shares as they wish currently, after no more shares are in an account, the order will just vanish by becoming invalid. I believe the 3535@0.75 BTC is still the "original" sell order by Tawsix (who is the ONLY person who cannot put up arbitrarily large sell orders).

That's kinda the opposite of a "dark pool"...

The rest of the offer will be cancelled once all of these shares in the acount offering it are sold, so in reality there might even be only a single share behind this (I'm not sure if it would even work with 0 shares) - or 1000.
Interestingly you can also put online sell/buy offers with 0 shares currently!

It's not really bad, you just can't know how many shares are really "behind" this offer, until it is bought up. It wouldn't matter though if there would be the max. amount of shares in the seller's account standing there instead, the outcome is the same.

Mining ist sowas wie eine Lotterie mit extrem(!) vielen Zahlen. Es wird nichts permanent gespeichert, daher kannst du auch keine "errechnete Leistung" mitnehmen - entweder du hast etwas gewonnen oder nicht.

Lässt du 2 Computer zugleich minen, müssen die absolut 0 voneinander wissen, sie werden trotzdem an verschiedenen "Glückszahlen" arbeiten.

Bei CPUs ist es mittlerweile sehr wahrscheinlich, dass die Stromkosten den Aufwand NICHT decken werden! Schau/rechne bitte erst genau nach, wieviel dich mining kostet und wie viel du an BTC erwarten kannst (vermutlich in einem mining-pool, solo muss man schon sehr gerne Lotto spielen um in solche Wahrscheinlichkeiten Geld zu investieren...).

http://mtgoxlive.bco.in/orders <-- difficulty increase, and BAM! 1.2 USD more...

1) It will remain quite stable at current difficulty if the hashrate remains stable at the current hashrate.
2) If it takes longer than 14 days to mine 2016 blocks, difficulty will go down to compensate for this. So yes, it can go down (and has already done so in the past once).

They could just take the time between last block + this block and calculate which hashrate you'd need to solve it theoretically in exactly this amount of time.

Very lucky short rounds would cause huge spike though, so these numbers then would need to be averaged out again, but it would handle difficulty changes very well + fast.

Could be even done on historic blockexplorer date quite easily. Anyone up for an afternoon challenge?

After a block has been found, Bitcoin waits until 120 more blocks have been found until the 50 BTC from that block are being able to be moved.
550/50 = 11 blocks have currently less than 120 blocks after them, so the money there cannot be paid out yet (if you donate 2,5% or more, eleutheria probably gives you a "loan" from his own pocket, until the 50 BTC from that block have been confirmed so you can already pay out directly after a block was found)

Could you do this for a longer timeframe too? Something along the lines of "since January"...

Also: On which data is this based on?

So wie er sich anhört, hat er noch ganz was anderes verloren/in Rauch aufgelöst...

1) Banken geben derzeit kaum Zinsen, wieso sollte ich also mein Geld dort lagern?
2) Ich kann z.B. 50000 "Dritteleuro" um 500€ "erzeugen" (falls da die Bank mitspielt... ) - jeder irgendwie logisch denkende Mensch wird NIEMALS Waren im Wert von auch nur 1 Eurocent für "Dritteleuro" rausgeben, da die beliebig vervielfältigt werden können.
3) Ist vielleicht eine nette Idee für Spielgeld (Monopoly?) aber als echtes alternatives Zahlungsmittel komplett ungeeignet, da beliebig inflationär und komplett unreguliert (BTC ist z.B. durch vorher festgelegte Regeln künstlich reguliert).


Ich würde ja gerne ein paar Bilder von (vielen!) erfolgreich "zerdrittelten" Euroscheinen sehen, mir klingt das alles SEHR theoretisch - und die Gefahr, dass die Bank sagt "da fehlen aber 34%, der ist ungültig!" ist auch nicht zu verachten!

Currently _all_ pools I know of take the transaction fees for themselves.
