Theoretically, the entire bitcoin network might not find a block for over 2 weeks; if difficulty wouldnt be adjusted to 1 in such unbelievably unlikely scenario, it might even continue for decades. Actually it might anyway, I dont know what happens to difficulty if no blocks were to be found for 2 weeks.

Hmm would suck if it created some race condition which caused the network to halt. Smiley
Let's all stop mining for 2 weeks and test it. :p

DeathAndTaxes - very nice ideas on block stats. Added to my list. Smiley

The duplicate proof of work message is new. Only recently did I add support for reject-reason to the server. And also, only recent versions of cgminer supports reject-reason. Probably same with other miners. BitMinter client will support it very soon.

About block solving rewards, it is on my list, so it's coming sometime. Smiley Kain, I think the transaction fees going to the solver is today not enough, and in the future too much. But triggering block rewards at a certain CDF level is probably a good idea. Once donations are working I think a solution could be a "block rewards" cause you could donate to. The collected coins would be paid out to the user creating the next high CDF block. Either pay out the whole block rewards pot at X CDF. Or pay out a share of the pot, proportional to how high the CDF is.

Another thought is that it may be good to always have a block reward even for fast blocks. A block reward makes a block withholding attack more expensive.

never seen that one D&T.  I'm trying to get 2 5870's to cooperate in windows vista...Bitminter is only recognizing one card, and I tried GUI miner, and it also only recognized 1. they both show up in hardware manager though.

You may have to reinstall AMD drivers after installing the second card, and you may have to reboot after that. If that still doesn't fix it, maybe you need to use driver sweeper and then reinstall AMD drivers. When I added a 5970 to my system that already had a 6990 it got pretty messed up at first.

Where do you find the instructions for joining using hashkill?  Also do you still have 0% fees and share the transaction fees?

Yes, still zero fees and paying out the transaction fees.

I haven't tried hashkill, but you should be able to get any miner to work by connecting to mint.bitminter.com port 8332 (use port 80 if a firewall prevents you from using 8332). As username put USERNAME_WORKERNAME where those are your username and one of your worker names on BitMinter. As password you use that worker's password.

You just made me a BitMinter disciple, Doc:

Yay!  Grin Nice low stale stats you got there! Smiley

He's got the powaaaaah! Tongue

In other, totally unrelated, news: buying GPUmax shares for BitMinter seems to work fine now. Just be careful when you enter pool information that you use http://mint.bitminter.com:8332. If you don't include the 8332 port number it will attempt to run through port 80. Port 80 mining is slower and more prone to timeouts and other issues. Only use it when you have firewall problems, not to channel massive hash rates from GPUmax. Tongue

Lately we had a lot of bad luck, and I estimate we lost about 10% of users and workers, and about 8% of hash power. This always happens when we hit a streak of bad luck, and the variance has always been a constant impediment to the growth of the pool.

I'm thinking about two ideas to solve this, and I'd like to discuss them here.

The first idea is to join p2pool. I don't really know much about it, but I see what I thought was a 0.5% fee is (at least these days) an optional 0.5% donation. Turning the donation off I could hook bitminter up to p2pool and still keep this pool zero fee.

Thoughts? Possible issues?

Can we still build our own blocks as we see fit and put things like BIP16 votes in it? Will we get orphaned shares in the share chain, the same way bitcoin blocks are orphaned (invalid)? I guess it doesn't matter as this should happen equally for all p2pool users.

I have many ideas for building my own stuff for cooperation between pools. But if p2pool can do the job, it saves time I can spend on other features instead.

The other idea I'm considering is a "share market" where you can sell and buy shares (proofs of work). Yes, it would be possible to make it similar to GPUmax so you can sell hash power to other pools. But I'm thinking firstly about shares within BitMinter. If you are worried about variance you can sell your shares at a price below their expected value and get a steady income. Like mining PPS with a couple percent fee. Other users who don't worry as much about variance can buy those shares. The buyer is the one that gets a score in the shifts and gets paid when a block is generated. As long as the share price is below the expected value of a share, the buyer is likely to make a profit over time. In the middle of that I can take a fee on share sales to get some income for the pool.

Seems a nice idea in theory. However, variance could make it too risky to buy shares. This is basically what operators of PPS pools do, and sometimes their results leave a lot to be desired.

Any thoughts?

I would be interesting in this. 

One "issue" is p2pool has a short LP time.  It is about 10 seconds between LP vs 300 or so between LP for Bitcoin (w/ merged mining).  It isn't a problem but the differences likely mean we will lose some % of our native hashing power as people flee to more conventional pools.  The good news is even if we fell back to say 80GH/s native we would have the variance of a 350GH/s pool (p2pool aggregate hashing power w/ +80GH/s from Bitminter).

The next issue is p2pool uses dynamic share difficulty and currently there are ~560 difficulty (I have one rig testing out p2pool).  Now you can obfuscate that from users by having them submit only difficulty 1 shares and then hand p2pool difficulty shares on to the p2pool network.

The last issue is "accounting".  When we solve a block we get 50 BTC it is very easy, very simple for users to understand and track.  If we are part of p2pool when p2pool solves a block we will get a "cut" of each block split by PPLNS.  You then can split that revenue like you do now.  Hypothetically if BM had 80GH/s and p2pool had 350GH/s we would get ~11.5 BTC per block solved.

At 350GH/s we would solve a block on average in 4.4 hours (or roughly 5 blocks per day).

Quote
Can we still build our own blocks as we see fit and put things like BIP16 votes in it?

p2pool works on consensus just like Bitcoin.  In any breaking split (like BIP16) 51% of the network will determine the course of actions.  If 51% don't support BIP16 then if you attempt to process BIP16 transactions it will be seen as invalid by rest of network.  Essentially it works like a "mini" Bitcoin in that respect.

Quote
Will we get orphaned shares in the share chain, the same way bitcoin blocks are orphaned (invalid)? I guess it doesn't matter as this should happen equally for all p2pool users.

Yes you will get orphaned shares in p2p share chain.  I get about 7% orphaned.  However they don't cost you anything.  p2pool provides a stat called efficiency.  If you have a 7% orphan rate and p2pool has a 7% orphan rate then your shares as a % of p2pool is equal to your hashing power.

orphans only matter if you orphan rate is higher than p2pool.  Currently I run at about 102% efficiency so I actually am picking up a ~2% bonus by being more efficient with my shares.  As a dedicated pool you likely could ensure you have hundreds of peers and fast connection which reduces orphan rate.

I have many ideas for building my own stuff for cooperation between pools. But if p2pool can do the job, it saves time I can spend on other features instead.

I really think p2pool could evolve to be p2backbone being a high difficulty network which connects conventional pools, major hashing farms and sub p2pools (made up of independent small miners).  I feel any work towards improving p2pool is better spent than reinventing the wheel.

I had considered running a pps pool which connects to p2pool.  I have been thinking of algorithms where the pps reserve would be "open market".  Essentially the pps fee would be based on buyers and sellers.

Still fleshing it out.  Now obviously this could work with a conventional pool also but honestly I feel p2pool is the future of mining.  It decentralizes control and only centralizes rewards.

Bitminter @ 150 GH/s has ~1.7% of the network hashing power.  IF the entire network ran on p2pool we would simply be paid 1.7% * 50 BTC = 0.85 BTC per block ... EVERY BLOCK.  Smiley  144 times per day, 52,560 times per year.

Now I doubt the whole network will move to p2pool but maybe someday 20%, 30%, 51% of the network is.

I did a clean install of vista and reinstalled the drivers. Not a big loss, as its only a mining rig Wink

There is no such thing as a 6990 driver.  AMD has been using unified drivers for years now.  What exactly did you install?
