Also the estimated coins/day is way off because of the "stuck" block.

Good luck,hope u can solve it soon, will be back than..

Can't login to cryptotrain pool, anyone else have the same problem?

As i've been watching this, primarily on bitember and cloudminers... the hashrate isn't dropping right as the diff nudges up, people are sticking with it for 100's of percents above the target. When it gets to >500-1000% is when i'm seeing miners drop, not right on the switch.

I think the point of Bullus' posting of the blocks was that the difficulty inches up, the amount of shares needed climbs up as expected... but on block 10,870 it takes millions of shares vs. 10s of thousands... the difficulty change was .8ish.

So people aren't seeing a .8 diff change and immediately changing their miners causing what you are seeing in the hash drop. I think you're looking at only the raw numbers in the hash rate without realizing that people are leaving the pools AFTER it gets stuck, not at such a minute diff change.

I'm used to being on pools and getting the occassional 200-500% block.... but what i'm also used to seeing is the block number increasing as other pools (that i might not be mining on) are finding it. Here all pools get stuck on the same block until for whatever magic reason it unsticks.

yep i can see them ( i think let me delete some old ones)

Will do.

yep, hashrate dropped off.  Why it happens have no clue, but working on a different targeting algo... this is brutal.

No need to delete anything in the future, this has been happening every so often last 2 days.

Because the stuck block difficulty will be much lower - the blocks you point out were found fast.

Wait will the next block hits, not the difficuly, then look at the block immediately after - see the difficulty, and you will see what I mean.

There are some things I'm looking at as organizer pointed out...  not to worry.  We will get through this.

During the stuck block, i was sending coins to bter.com and also receiving coins from the pool..but it isn't even confirmed (they were grayed out) .
Now i deleted everything except wallet.dat en conf and resyncing again...i think bter.com got the same problem if a block is stuck?

PM me the date and time when you want to fork.
I will make sure to update the wallet on the pool.

I suggest after 7PM GMT +1.

same here no confirm, I event cant get into the web interface, it keeps showing the login page. Even resetted my password.. cryptotrain anyone else?

I also think that we need to fix something here and do it as soon as possible. But first we need to locate the problem. In my opinion it is difficulty retargeting scheme. Did anyone see a similar problem in another forks?

no blocks again!
and no tran,no confirm,no trade!

Please don't even think about implementing DigiShield in this coin.
Its even worse than KGW for smaller coins.
Will maybe work fine for Doge but it will kill Flutter for sure.

TheKidCoin do you read your PMs or is your Inbox already spammed?

Its very clear what it is, blocks don't just magically get stuck LOL, they are just too difficult to find when the hashrate drops 50% + what the calculated difficulty was (which is exactly what these exploits can do).

For example say hashrate is supposedly 2 gH, and a block is calculated to be 50 difficulty, then suddely the hash drops to 1 gH, what happens it is VERY difficulty to mine the block at 1gH

This is one thing that was brought to my attention yesterday - which explains why pools on the correct chain were showing much more hashrate than was reported on the rest of the network https://bitcointalksearch.org/topic/attention-all-stratum-pool-admins-513382

I am definitely looking into these things, but remember, dogecoin is a POW coin I believe - there are a lot more moving parts in this coin...  If anyone knows people like Sunny King, Balthazar etc and is willing to ask them to take a look, it would be appreciated.  Or any other Dev that can make an educated guess for that matter.

We definitely will need to fork the coin in the next week - there are other things I want to put a stop to - not fix, but adjust for the better- so whatever this fix is it will be rolled in the next few days and the fork will happen no earlier than 7 days forward - unless we can get agreement with bter, and all pools to implement the update quickly.  Any ideas on the warning/window needed to implement a mandatory fix is also appreciated - if it can be done with 3 days warning or so, thats fine too.  Bter really is the key.

Is something up?

Been 40 minutes+ since last block on 3 pools I've been watching. 

If u say it is because of the diff of the block, why block 10867,10869 is finding it alot faster with the "same" difficulty?
See the share differences.

Another stuck block?

switching my rented rigs 

I'll stop posting after this for the day, but BTER was having issues with the chain too:



Then:


This type of stuff will scare people away from the coin.

Don't follow what your saying

I'd just like to be able to leave my rig on FLT. I still don't think this is a hashrate/diff problem and would like to see some potential attempts to solve it...

Maybe look into implementing the DigiWave thing the DOGE people are putting in place in lieu of KGW (which can be exploited too), which would help as the coin gains more attention.

How come block 10867,10869 is normal than with the same diff?
