OK, the rewards were recalculated. To compansate all moral damages I don't take 2% fee for rounds 6933 and 6934, but instead I give you 1 BTC extra. Those rounds are worth for you 51 BTC each.

If for anyone the rewards for those two rounds were not recalculated correctly, please report here and I will fix this tomorrow.

The issue wasn't that we were in a 5 hour block, it was that for over 2 hours the account page wasn't showing a true total of shares submitted. It just stopped counting them, or so it appeared.

Looks good now, Slush.  Smiley

If I go to https://mining.bitcoin.cz/ or https://mining.bitcoin.cz/accounts/login/?next=/accounts/profile/ , it stays secure but when I login, the website takes me to my account unencrypted. Could you please implement a certified SSL Server Certificate to your site? Also to stick to HTTPS at any given time connected to mining.bitcoin.cz? Or an option to stay connect securely after logging in?

Hi pekv2,

I worked around this bug with the Firefox extension "HTTPS Everywhere" (https://www.eff.org/https-everywhere). In order to work with the pool's site you have to create a custom ruleset (as described at https://www.eff.org/https-everywhere/rulesets).

For mining.bitcoin.cz it looks like this:
Code:
<ruleset name="mining.bitcoin.cz">
  <target host="mining.bitcoin.cz" />

  <rule from="^http://mining.bitcoin.cz/" to="https://mining.bitcoin.cz/" />
  <securecookie host="^mining\.bitcoin\.cz$" name=".*" />
</ruleset>

Put this in a file called mining.bitcoin.cz.xml in the HTTPSEverywhereUserRules folder in your Firefox profile. After restart you will only ever see https for the site. Also your cookie will be marked  as secure and thus only be sent over https. Maybe you have to log out and in again to have this take effect.

For the two rounds in question, I am still not seeing any reward. I believe I started mining for the day fairly early during the 5 hour round.

Thanks for looking into this issue and all the other work you've put into this pool.


EDIT: Slush credited my account for what was lost during these rounds. In fact, he gave me more than I probably would've earned. Thanks.

slush,

I haven't seen any discussion of merged mining on other block chains like namecoin here yet (at least, no hits on a search of this thread). Are you working on this?

https://github.com/vinced/namecoin/blob/mergedmine/doc/README_merged-mining.md
http://dot-bit.org/Merged_Mining

Basically, we can earn namecoins and bitcoins at the same time. It sounds crazy, but it appears that there is no loss of bitcoin hashing power when adding namecoin mining. Just additional free profits. The only thing needed to enable this is changes on your end.

Or are we already mining namecoins for you?

Thanks!

This will start working at namecoin block 24000. Current namecoin block is http://explorer.dot-bit.org/  18000. So still plenty of time - it is impossible for pool to mine minecoin right now.

Also, mining is finding a nonce against a hash of merkle tree of whole block chain. It is not possible that two different chains (namecoin, bitcoin) will have the same hash of merkle tree. You cannot look for a nonce against two different hashes of merkle tree, it must be one of them. Can you point me to the exact description of implementation and math involved, how namecoin has to be modified to get this to work?

Because currently it would be for example spending some percent of total power on minecoin and the rest on bitcoins, which isn't what people want (less hashing power going to bitcoins?).

Ah, so we have about 42 days (1000 hours) before this is possible if namecoin averages 6 blocks/hour.

That's exactly what I thought (that you couldn't have one hash work for both), but I was wrong. I'm not an expert on this, but my understanding is that they will both accept the same hash if it meets their current difficulty requirements. I had to read lots and lots of posts and wiki pages before I finally understood this. One post which helped was here: http://forum.bitcoin.org/index.php?topic=30294.msg393412#msg393412

Basically, namecoin has been modified to accept bitcoin hashes which contain the namecoin merkle root hash in the bitcoin block. The bitcoin protocol doesn't care, and you get free namecoins for the bitcoin hashing you were already doing.

There will be more and more alternative chains, and miners are going to want to get as much value out of their hashing as they can, so this will become an essential feature. The pools will probably just sell the namecoins for bitcoins, take their cut, and distribute the rest of the extra bitcoins to the miners.

1 block each 6 hours is closer to the reality nowadays  Grin

Block 20160 is estimated to get reached on 30th November, so block 24k is supposed to get reached more more long than 42 days...

We are under attack, bear for the fight. One backend just had loadavg above 12.0.

EDIT: ok, I think that problem is fixed now. But I will keep an eye on that. Some of you might have lost connections, but your miners should reconnect automatically.

So unlucky lately, so many blocks over 1-2 hours and some over 3! Isn't the average share number around the difficulty number?

I think your algorithm is broken I can come in the middle of a two hour block

and get nearly the same payout as someone who has been there the whole

two hours. The older shares are being weighted, scored way way too low.

-------------added
so could mine at btc guild for 1hr 50min [see CDF ]payed out proportionally

and then goto slush and be caught up with everyone in a few minutes for

a sweet score based payout

Raulo made proof that this approach will lead you to losses because you don't know when the new block starts on other pool (btcguild and deepbit hide their stats) and because you never know when the block will end on this pool, he wrote some .pdf article about that:

https://forum.bitcoin.org/index.php?topic=1976.msg50002#msg50002
(it's linked from there)

No matter if round just started or if it's already going for 5 hours, the probability of solving it is still the same.

This approach also allows real-time stats of solved blocks here. With share based payouts, if you knew when block ends you could join for short rounds and get full payout. This is why btcguild and deepbit have hidden stats.

I see that one of my workers has found 1 block, somewhere in the past..
Is it possible to know which block it was?
