Normally your measured hashrate is used. X-Mining-Hashrate, if available, is only used in the beginning when the server has not yet measured your hashrate.


This is per worker.

Testing is up on port 9000 again. This time testing dynamic difficulty (aka var diff or variable difficulty).

Please help testing: mint.bitminter.com port 9000

Difficulty is from 1 to 128 (powers of 2). The default is diff 2 unless your miner sends X-Mining-Hashrate in which case the default is based off of that. After this the diff updates every minute based on your hashrate.

The target is set to 15 proofs of work per minute. That's one result sent in every 4 seconds. The server will adjust the difficulty of your work to get you as close to the target rate as possible. You will need a couple GH/s to get over diff 1. No luck for me with 1.3 GH/s

When mining at diff X you get credited X accepted work for each valid result sent in. So mining at diff 4 means your "accepted" numbers will go up by 4 for each valid result.

Like last time the livestats won't show your hashrate on the test port. But you can look at the "workers" page on the website, mine for a bit, then refresh and see that the accepted work goes up. Note that those stats are a few seconds delayed. The livestats will work better once proper multi-server support is finished on the server side.

You can't use BitMinter client for this yet, sorry, multi-server support is still on its TODO list.

Let me know how it runs.

There's also Bitcurex. Their debit cards are very nice. At this moment there aren't many BTC buyers though.

Another mint race coming up next weekend with some nice trinkets from Isokivi for prizes.

Check it out: https://bitcointalk.org/index.php?topic=120864.0

BTC trinkets (Isokivi @ bitminter and bitcointalk) is kindly offering some very nice trinkets for a third Mint Race on BitMinter. It will be similar to the first and second mint races. The finest quality minting work (lowest hash value) will win.

Start: friday 2012.11.02 at 20:00 UTC
Finish: sunday 2012.11.04 at 20:00 UTC

Prizes:
1st place: Bitcoin cufflink pair + 5 BTC
2nd place: Bitcoin tiepin + 3 BTC
3rd place: Bitcoin lapel pin + 2 BTC

Currently cufflinks are selling for 3.25 BTC, a tiepin for 2.5 BTC and the lapel pins for 2 BTC. You can see pictures here: https://bitcointalk.org/index.php?topic=120686

If you don't win you can of course still buy the items you want. See the link above for more information.

Rules:

• Just like your hash must beat the difficulty to produce a block, it must beat the other miners to win. The best (lowest) hashes during the race will win.
• As long as your work is accepted by the server it is valid for the race, even if it ends up "stale" or "orphaned" in the block list.
• Each person can only compete with one (their best) hash.
• If a winner cannot be reached within 1 week, the prize will go to the next on the list. You may want to make sure that the "account details" page at bitminter.com has an email address listed for you so that you are easy to reach.
• Any block by Isokivi or DrHaribo will not count in the race.

Verifiability:
Hopefully your mining software will show if you have created a block (BitMinter client does). Your block will show with your user name in the block list at http://bitminter.com/blocks. You can click the height number for the block (leftmost column) to see details. There is a link there to blockchain.info where you can see the hash value of the block both on the page and in the URL. The lowest hash value wins. Hash values are shown in hexadecimal. 0-9 is lower than A-F. A is lower than B. Pretty simple.

Updated 2012.11.04, 17:00 UTC

14 blocks in the first 10 hours of the (UTC) day. This should be a pretty good day.

What is miner quad mode? Do you mean ModMiner Quad FPGA? It is not supported in BitMinter client. You will need to use a different miner.

This was with myopenid.com? Their service is a bit unreliable, but it seems to be working again now.

How can it be harmful only for hoppers when you take money out of all user accounts?

You made the switch to PPS retroactive and took back money that had already been paid under the old system. Most people who run a bitcoin service would not dream of doing something like this.

Hmm, looks quite nice. I had not seen that before. The plan was to use nagios (http://www.nagios.org/), but I think I will do a little research and see what my options are. Monit looks like it may be less hassle.

Yes, just before WKNiGHT made his first block on minter (congrats!), all the payments finally went out.

It was a bug in namecoind that first caused payments to fail last night. I fixed this by restarting namecoind which had locked up. But this had in turn triggered a bug in my own code and some payments would not go out until I could locate and fix this issue.

My apologies for the late payments today. Everything should be in order again now.

After fixing the stuck payments earlier today some of the payments still didn't go out. Fixing this as soon as possible.

Sorry for payments not happening for a few hours. The payment processor was stuck on a namecoin payment with a namecoind that was just not responding. I suspect alt coins have a lot of old bugs that were fixed in bitcoin ages ago. I'll need a watcher mechanism to detect when namecoin locks up.

Namecoin value is up lately, so they are a decent income boost for miners now. Not so sure about adding merged mining with other "bug coins" though. The alt coins just aren't properly maintained the way bitcoin is.

Anyway, all payments are out and things are back to normal again.

Another thing; many are asking about why BitMinter has produced some blocks with only 1 transaction lately. This is part of the many changes I made lately to better handle the issue with old miners randomly attacking the server. If you run an old version of cgminer or bfgminer your requests to the server go on a separate queue where you get work more slowly than everyone else. You also get work for producing 1 transaction blocks because it is slightly cheaper to make.

If you run a cgminer or bfgminer version below 2.7:
You are causing yourself and all other miners to lose transaction fee income on the blocks you make. You were causing slow server response and a high reject ratio, before these changes. You are getting work slower than others on the pool. You are probably getting more stales too. I know this isn't something you intended to do and you may not have been aware of it before. But you are running a very old miner version with some serious bugs in it. Upgrade today!

Looks like Apple broke Java 6 in the latest update.

If you are having problems getting BitMinter client running on Mac OS X, there is some info about it here:

http://stackoverflow.com/questions/13004854/is-there-any-way-to-reenable-javaws-with-java-6-on-osx-lion

Remember you can start from command line (if you get javaws working with the instructions at that URL):

If I read the timezones right, Fcx35x10 won if you go by any other timezone than EST (east coast US). Including the other 3 american timezones.

Let's be honest now. You took money out of the accounts of your users because you wanted a buffer to run PPS. I agree PPS is very dangerous for a pool op and you need a large buffer to even attempt it. But you can't just take other people's money.

Can you understand that the people in this thread are unhappy that bitcoins suddenly disappeared from their accounts?

https://bitcointalk.org/index.php?topic=50779.0

The thread has a google translation of the explanation from your site. If it's not stealing, then what is it? I think you should apologize to those miners and give their money back.

A day late the prepay perk has now been disabled for users with donations set too low, as announced earlier at https://bitcointalk.org/index.php?topic=27062.msg1250147#msg1250147.

If your perk has been disabled then your donation has also been reduced by 1% which was the old cost of the perk that is now disabled. Have a look at your perks and donations and decide whether you want to make any changes.

Deepbit seems to be in 2nd place, not 3rd?

Awesome stats though, I like the new "loss to poolhopper" stats.

Bitcoinium (for Android devices) now supports BitMinter for pool stats.

Is this service still alive?
