Stratum mining allows LTC pools to achieve less than 0.5% stales. The only current pool to implement it is ltcmine.ru. If you check out their list of miners there, you will see that many are mining with quantities of stales as low as 0.2%. Latest version of cgminer to support it is 2.10.2 The reaper version that supports stratum is here: https://bitcointalk.org/index.php?topic=92522.msg1372243#msg1372243I think as a community we work on getting stratum support for more pools, so that you guys pool mining all get more litecoin. Currently, PoolServerJ supports both litecoin mining and stratum.

What ? As far as I know, the official poolserverj has no stratum support and scrypt support is still broken.

Isn't poolserverj the backend for ltcmine.ru? Unless I'm mistaken

No, we are not using poolserverj for ltc pool.
Don't know about cgminer, but our stratum-mining-proxy fork works fine.
There is a mistake in first post, our reaper fork doesn't support stratum for now, and i recommend to use it in combination with our proxy. But it's planned to implement native support.

Tested cgminer 2.10.2, and it's doesn't work. So, our mining-proxy is the only way to mine through stratum/ltc, for now.
P.S. I've planned some changes in LTC version of stratum protocol, to make it more correct and clear (in terms of difficulty, for example).

Care to explain why cgminer natively doesn't work? Is the problem in cgminer or the pool's stratum implementation?

I think that cgminer uses 0x00000000ffff0000000000000000000000000000000000000000000000000000 as the maximum target for LTC (instead of 0x0000ffff00000000000000000000000000000000000000000000000000000000) while current target calculation, but it's only my guess. If I'm right, then it's actually working, but sets unreally hard difficulty for shares... And as a result, miner can't solve it.

Yep, here's my patch. http://pastie.org/private/b5jve8ebgynaidu3yv22areplace set_work_target in cgminer.c with that one, if someone could post a windows build with that it would be nice since I've only compiled this on linux and I have no AMD cards anymore.

Unfortunately, I can't check this patch on my current machine, because it have no opencl support and cgminer can't mine scrypt on CPU.

Updating the mining guide with more information on how to run stratum correctly with ltcmine.ru
if you are getting high stales make sure you are using the mining proxy!

It's not a stales. It's just an invalid shares.
