Not sure I understand what you mean by compromising the network.

Well say that people join a pool that's being run on a server that belongs to someone who want's to attack the network and compromise the chain with fake transactions. I read countless of times on these forums and in the wiki that something like is impossible because someone would need a cpu power to match at least 50% of the rest of the network. Well isn't that what a pool is? Basically a server with the power of loads and loads of CPUs combined?

Could pools get so big that the difficulty gets so high ...
difficulty gets higher with more network-hashing-power, doesn't matter if that power is pooled or not.

...wont be worth mining...
not a matter of difficulty, or hashpower at all.

Could pools get so big that one pool could have enough hashing speed to actually compromise the network?
in theory, yes.

From what I understand, it's actually approaching that fairly quickly.

Could pools get so big that the difficulty gets so high that not being in a pool even if you have 4 GPUs of your own wont be worth mining anymore unless you also join a pool?

Yep - I understand my statement lacks logic...

Something about seeing rewards getting smaller is disappointing (even if they are more frequent)

I would be pleased if [Tycho]'s pool stayed right around 30-35Ghash  ;)
Why ? :)
I imagine because with more the proportional share gets smaller and smaller for those with high speed hashing.
Yes, is gets smaller, but more often. Overall reward per hour/day will be the same.

What's the number in the bottom right corner on your web-site for? It keeps changing every time i switch pages.
It's time spent for generating this page. Not connected to the pool at all.
Letters and numbers at the bottom left corner is bitcoin address - you can send donations there :)

This is little offtopic, but the right reason why I closed registration was that in the some point pool started to grow exponentially (difficulty was low, bitcoin price was high and somebody slashdotted it) and I was too slow in adding more and more bitcoinds Smiley. For current pool users, there is no reason for making pool even bigger; more ghash/s does not add any benefit for them.

[Tycho] I don't know if you mentioned this before but are you going to limit to how many users can participate in the pool?
No, i'm not planning to set such restriction.

But maybe no, because you know (from me) that there will be problems with bitcoind. That's the point. Btw, my pool software (not bitcoind) can handle thousands of getworks per second and I never had problems with speed of my custom software.

(Bts it's nice example of another issue, in the times when I made the pool, running more instances of bitcoind on the same machine was not possible because of hardcoded listening on the 8333 port.)
Ok, sorry again for this, my statement was unsuitable. You are doing great work and thanks for info about bitcoind.

[03:51] <[Tycho]> On how many getworks/sec did you started to get problems in the first time ?
[03:51] I think around 30ghash, not sure which getwork/s it was

Nobody is lying here. Yes, in my case on 30ghash/s the bitcoind started to fail. But it is not related to hashrate, but to getworks/sec. As you're using the same core as me, you'll hit the same problems later.

But maybe no, because you know (from me) that there will be problems with bitcoind. That's the point. Btw, my pool software (not bitcoind) can handle thousands of getworks per second and I never had problems with speed of my custom software.

My pool software is much more efficient, so i don't see any problems with number of clients.
Hehe, don't say this - you are still on 30ghashes, I had no problems on this speed, too (and also don't have problem at current 90ghash/s).
Quote from: slush on March 03, 2011, 12:25:03 PM
I never had troubles with speed of pool software itself and I see your statement as little unfair, because you didin't have to solve 90% of troubles which I had. Just my 2 cents...
I was talking about all the pool complex in total. Sorry, no offense intended.

And please don't forget that lot of issues was caused by non optimized miners; I spent weeks with miner developers to find those glitches and bugs. The last huge improvement was support for long living HTTP connections, this was the reason why I closed the pool registrations, because hundreds of miners connecting every few seconds literally DDoSed the server with SYN floods.

That's a lot of luck.

At 1.5 MHash/s (about twice your speed) I've generated 69 shares in 48 hours.
