according to https://bitcointalk.org/index.php?topic=104664.0 this pool does not do DGM, slush said he was going to implement DGM many months ago - but never did

Hello Graet,

thank you for your correction. DGM was the name for slush's payment method that I found in a note to the pool. I always wondered whether this was really true as it didn't match with other statements in the forum.

In the forum notes I found, nobody ever gave a name to the method applied but I think one may call it Raulo's method, exponentially weigthed payout, "slush exponentially scored mining" or the cooperative sharing method. If there is a name to it, I would be glad to know it. Slush exponentially scored, as in your reference, is not too helpful in my opinion.

slush invented the not quite hopper proof payout system and only 2 pools use it, Slush exponentially scored is as accurate a name as any (I do not choose the names for payout systems)
DGM is very different to slush's method.
https://bitcoil.co.il/pool_analysis.pdf is a comprehensive guide to payout methods - well worth a read

Slush congrates on the "Slush Pool 2.0" upgrades! I have been with this pool from my start of mining and wish all here a prosper pool future!

[Rishodi]

How is variable difficulty being calculated? I ask because I have a stratum proxy running on a server with several miners connecting to Slush's pool through it, all using different worker names. It looks like the difficulty is being adjusted based upon the total number of shares being submitted through the proxy and not on the basis of individual workers. I'm guessing that difficulty is calculated independently for each connection, as all my workers use a single connection to the pool, but just wanted to verify.

I just hope the the new and improved Slush 2.0 solves this long-assed block soon and moves on

Pool luck (1 day, 7 days, 30 days): 135%, 98%, 106%

Pool luck looks normal so maybe its just the new mining world with these high difficulties and so many different pools and large solo miners. You can only cut the pie so many times until all the pieces look to small.

I'm pretty sure that luck reflects the results of the previous block found, not the current block. when this one resolves, it will drag luck down.

What Slush 2.0?  Did I miss something?

Hello MinerTE,

When I launched mining.bitcoin.cz in late 2010 I didn't really expect the pooled mining concept to become such a success. At the beginning, mining was accessible rather to geeks but gradually the expectations towards a mining pool service have changed a lot.

My goal now is to introduce completely new features and cutting-edge technologies that will make mining accessible to newcomers as well as keep mining.bitcoin.cz attractive for advanced users.

A few months ago I started to make preparations for a new edition of the pool - Slush Pool 2.0. The changes will be gradual and will lead to better user experience. The result should be simply a stronger pool with some great new benefits for you.

Consider today's news as a warm up. In a short time I will release a few more enhancements.

Thanks for being with my pool and good luck! :-)

New Support & Development Team
I have increased my team by two new members Pavel and Jan. Pavel is responsible for bringing new pool features meanwhile Jan is taking care of the infrastructure and stability of the network. Both Jan and Pavel are experienced IT professionals and close friends of mine for more than 15 years and I fully trust them to provide a very dedicated service to the pool. For the last couple of months they have been working alongside with me and are now fully operational. It's also thanks to them that several new features could be deployed.


Vardiff - Slush Pool 2.0 ASIC Ready
The first crucial feature that I'd like to introduce has been deployed three weeks ago and it works pretty well. It's called variable difficulty, or simply vardiff. Vardiff protects the pool from being overloaded by strong ASICs and helps to easily manage the stream of shares from miners to the pool. It creates no impact on the height of your rewards. Having implemented Vardiff, the pool is more stable and truly ASIC ready without any need for manual setting of the difficulty by the user.

FAQ: How does Vardiff work?

Infrastructure boost
We have invested significant time and resources to improve our server infrastructure during the past several months.

Although these improvements are less visible, they are our top priority. Today's infrastructure provides better security and reliability on multiple levels (fallback scenarios, multiple distributed services etc.) and next tasks are on the list. The new infrastructure opens an entirely new space for building cool features on top of it.

Minor reward system changes
While working on completely new and quite exciting rewarding system, we've changed some settings of the current one in order to improve stability (e.g. decrease variance) in miners' income. It has already been deployed.

The change is about altering shape of used scoring function. The function is now less steep than before which means that your submitted shares influence your score for a longer time period. Therefore your score is less sensitive to instant luck of your miners and this leads to a lower variance in results.

Thanks.  Though I visit this thread as much as I can, I obviously missed this news somewhere on here.  How long ago was this?

Ten-and-a-half hours and counting.  Prepare the virgins, newborns and the chickens.

That is correct. A round does not factor into luck calculations until after a block is found, and when the current round is over the daily luck is going to drop well under 100%.

[Go3Team]

12 hours and counting.  Ouch.

[CroverNo01]

14 Hours and counting 

[scooter]

14 Hours and counting 

Why is everyone counting? That only encourages the count to go higher!

[sifo]

These updates don't look promissing to me.
15 hours and counting. :`-(

Ok I have a question, since posting the pool's luck and the block is still ongoing why is the 1 day pool luck going up when nothing has been found for us? It seems as this block (over 14 hours now) continues that the 1 day luck would adjust down not up, as we see in the 7 and 30day? No big deal just more curious than anything else.

 Pool luck (1 day, 7 days, 30 days): 179%, 96%, 105%

I guess time spent on active block doesn't count.
And just berofe this block, we had quite quick rounds, so luck looks good.

[sifo]

There it is. 15h round done. I hope it will be valid.
