i cant sync my wallet either 

My both pools lost connections - what is happening? Can anyone provide some addnodes?

Yeah, current implementation is faulty on forced retarget. It will only be triggered if one block takes more than 4 hours to find.

Fix is on its way, haven't had time before.

We have to be careful using single block times to do anything, because this is a random process. I like the 5 blocks in less than 2 minutes causing a retarget. How about the forced retarget is 2 hours, or less than 12 blocks in 1 hour, or alternatively forced at 2 hours, or less than 6 blocks in 30 minutes. Currently we are looking at the last 30 blocks for the retarget, I propose in the 5 blocks in 2 minutes, or <6 blocks in 30 minutes that we use the last 15 blocks to calculate the new difficulty. This will dampen the effect and reduce overshoots.

Just a note. It looks like the current 4 hour force retarget isn't working. Can we debug why we aren't getting a retarget after 4 hours. Let's get that fixed, and also add the quick retarget up based on 5 or 15 blocks, and target that for 3-4k blocks away.

Or if I am reading the block chain wrong, let me know.. We should have seen a retarget on 28988.

Port created. Here are the details:

http://mnrb.coinmine.pl
Getwork: 8197
Stratum: 9197

To all users on http://nrb.coinmine.pl - please withdraw your coins and migrate your accounts to above pool.

i think thats great, lets have a super quick diff adjust, quick to rise and quick to fall, it will force multipool and crypto switchers to make a decision. if we make adjustment every 3 blocks with ridiculous rises and immediate falls, it'll rid us of them.

Yeah, if you set up getwork I'll migrate.

I can set up getwork port as well but really want to migrate everyone...

Is it stratum only? Because it is a bitch to configure with CudaMiner...
Also, I'm really not interested in multimining, so I would rather stay with the old pool..

Yeah, the core idea in the suggested solution is to give up on fixed retarget intervals. Every block becomes a potential retarget point depending on how fast/slow the last N blocks get found. N needs to be picked so it is high enough to compensate variance, but small enough to react to network spikes.

we'll have to develop a resistance to coinchoose/coinwarz and multipools. Perhaps a readjust that pushes diff up sharply if 5 blocks are solved in under 2 minutes, by a factor of 5? that should instantly kick off the multipools. Then if a block is not solved in 20~30 minutes difficulty reverts to previous level?

Multipools, multimining - shooting a bullet in your feet...

Do you guys realize that it's gonna kill coin after coin ? Unless it's the intended goal, of course...

Announcement about http://nrb.coinmine.pl:

I am trying to get rid of old/crappy/buggy mmcfe implementations and this is a part of it. We opened nrb pool based on actively developed mmcfe-ng which is far more reliable than old frontend. Please migrate your accounts to new pool:

http://mnrb.coinmine.pl
New stratum port: 9197

New pool has 1% fee (connected with MultiMine service) but for all users registered on old site fee will be 0% - please notify me via PM or email [email protected] once you create new account.

There are several advantages and new functionalities on new pool including system-wide accounts (you will have one account/workers for all new pools on coinmine.pl)

i agree, they threw +100mh in less than a minute!!! Let us begin a new discussion to deal with all current issues so that the next update is all inclusive.

I'm starting to think it's time for yet another retarget algorithm... multipools are gonna kill the coin otherwise.

Implementing oatmo's suggestion is getting critical.

yes it appears so, they sent an email.

Hummm... is there a multi-mine pool dropping in on Noirbits ? I'm definitely gonna have to push the difficulty retarget for blocks going too fast...

Give it up...

I don't think the guy will ever admit he missed the link on the first post because it was not highlighted in shiny blue and that it actually required him to read the post. And snaidervp was right, despite my belief that all animals should be fed, trolls are an exception


On an another topic, refunds are coming along nicely, should be comitted within the week (RPC call only at first, initiated by refunder only... I'll add a protocol extension later to have a sender request a refund, but still subject to the receiver's agreement).

If you ask politely, we'll help. Welcome to the club.
