Well, if you read the official Grøstl Hash function website, one recognizes that the FH-Wiesbaden developed Grøstl FPGAs in 2009.
And if you continue reading, Mr. Stefan Tillich already developed an ASIC for that hash function not much later. The question is, if those technologies already have been sold, or rebuilt in some way.

My first assumption would be, that there exists only a small number of FPGAs and ASICs in educational environments and the difficulty fluctuations are some kind of "scare tactics" from somebody with huge GPU hashing power.

http://www.groestl.info/news.html

Going POS only is the only way to really do that.
But that also cuts out your GPU mining.

 


EDIT
Unless this new Algo by Feathercoin works.
http://www.feathercoin.com/neo-scrypt-press-release.pdf

just do something quick and dirty to make it impossible/too costly for asic or fpga to mine.

All,

I am/was mining at 138 mh/s while all of this went down and it appeared to me that the issue was in 3 waves based on what I saw with the difficulty.  It was hovering around 130 yesterday and then plummeted to 19 or so.  I went to coinwarz to check their stats and the site validated what I was seeing.  At that point, it was a head-scratching moment but I thought that a pool went offline, such as what many are suggesting.  It stayed around 20 for about 20 minutes and then started to creep up again until it went to 100 again.  Then it went down again to 4.  It went back up to perhaps 40 or so and them went to 0, all the while I was mining.  I checked/refreshed coinwarz again and it validated the 0 difficulty again.  Last night I checked coinwarz and cryptsy again and it was showing 130 difficulty, even though I was seeing difficulty at 3.  My rig is still connected and mining, basically because if there was an issue and I ended up being the only miner on the network, I wanted the advantage.  And, even though I have not lost connectivity to the minter, I appear to be on the fork versus the correct chain.  Let me know what I can do to get any info to the group.  I used to be a follower/miner of the coin and lost interest for a while and decided to give it another try after finding I can have a high hash rate with the new algorithm. 
As of yesterday, when I checked the network hash rate of the "new" difficulty, it showed around 300 mh/s with me using 138 or so.  Perhaps another miner on the same chain? 
But why would I not have been on the "real" blockchain all along if I never stopped mining and continued to solve blocks?
Anyway, let me know what I can do to help shed light on the situation.
 

FYI:

Paths Diamond has to chose from (Once you start heading toward asics):

1st Path Make diamond into a multi algo coin including scrypt , which already has asics.
Groestl, Scrypt, & POS

2nd Path , POW only
it would probably make more sense to drop the POS and get yourself added to merged mining with Litecoin & Dogecoin in scrypt based asics.

or

3rd path Drop all POW and focus only on POS.

or

4th Leave everything the way it is.


IMO these are what choices can lead to from this discussion.
Good Luck

 

Everything will depend on the capitalization of diamond and its value.
If capitalization reaches $ 1 million and above (for a long time) then Asic miners for the groestl algorithm will certainly appear.

groestl is part of x11
if people develop x11 asics pure groestl mining as alternative ability will be a sideeffect most likely

The question is: is there enough volume on groestl coins to warrant asic development?

discussion ON

we will read with interest what the community think about this topic

fact is the diff did nearly tripple

are there 3x more GPU miners than before?

we also see the x11 miners on http://multipool.bit.diamonds/ did increase a lot too
so some DMD friends with gpu miningpower left direct groestl mining and mine via multipool their DMD

could that be the path?
to ignore if a increasing part of DMD is landig in hands of (china based?) fpga miners
(i dont think asics are here already)

and use DMD Multipool and DMD Cloudmining at the "investor" path to mine DMD
(as additional way to earn DMD beside just buy them on exchange)

maybe even some fpga owner can tell us
where they get the gear  from
who programm it
how expensive it would be to buy pre programmed groestl mining FPGA

I am not aware that ASIC's and FPGA's are using Groestl - Do you know something?

please update the algo to make ASIC and FPGA devices unable to operate on DMD.

sooner the better please.

I don't need the Shoutbox really much, I think more important for the pool would be a working download section, maybe even with preconfigured batch-profiles, as less tech savy people are not able to put these things togehter.

Hi Stillontop,

Thank you for your support, glad you like the new Pools =)

Yes, you should connect to port 3388 with that speed.


Btw, Would you like to have the Shoutbox on the new pools?


Thanks for mining with me

Hello miningfield, thank you for polishing your pools around the world! My 290X is already crunshing numbers in EU, just like before
I am already considering a donation, if the pool remains stable for some time, I will do it for sure. Keep up the good work guys!

My card spits out around 24.x Mh/s, I hope that qualifies for using the 3388 port, I don't want to belong to the lamers on 3387

that we will find out when we talk with someone
able to provide a android wallet with POS abilities

we dont seek a copycode solution with diamond UI
but the guys who deliver android wallet must be available for longterm support and upgrades of wallet too

all our partners have a longterm relationship with us
we dont believe in "fire and forget" jobs
sustainable cooperation is the way to success

thx for feedback from everyone

situation now

network recovered
cryptsy multipool/cloudmining and the major mining pools (danbies and miningfield) are all on main chain

if u wana see if u are on mainchain
http://dmdpool.digsys.bg/bc/block_crawler.php
show the highest block in good chain
(refresh with F5 it dont autoupdate screen)

analysis will follow
but i dont belive in a accident.....
looks like a intended attack

if u didnt before make sure now u add the line bantime=600 into conf
without that line even if our wallet code allow forked wallets to reunite again with mainchain
they cant because u block them for 24 hours........

if u dont allow someone talk with u
u cant tell him that he is wrong......

pokeytex, thanks for using my pool as reference

By the way, the pool and the block explorer look at different wallets, so in theory my pool could get forked too.

I was offline for few days, having the luxury to be seriously ill and sort of missed this fork. I am glad you guys are back in the main chain, but could we collect some information as to what happened? running the (forked) wallet with

debug=1
printjunk=1

(at least) should record some useful information in the debug.log file. We need to find out what caused it -- I was investigating the sudden drop in difficulty, but about the only explanation I could find was large portion of heavy miners dropped off the network (they forked, apparently).

If you will remember, few months ago we had more such occurrences. The ultimate cure for this is some discipline in maintaining peer connections, as there are apparently people who like to experiment with other's resources -- no surprise, Diamond has become popular again.

There were lots of suggestions earlier in this thread how is better to setup your wallet's connections. In general, if you are block generating node (PoW, PoS) you should refrain from 'fully' participating in the network. In such cases, you should not listen for external connections to you (listen=0) and you should only connect to known good nodes that you are sure run valid software. It is also best to use connect= to these nodes, as to not connect to more nodes than you intend to. We publish a list of nodes that are well dispersed geographically, so should be safe from network outages.
If you run larger mining operation, you could set up your own 'master' node and have the actual miner wallets connect to it only/too etc.

The reason for all this 'trouble' is that if you have lots of hash power, you are an good target for an attacker, who would trick you to fork out by providing you with 'convincing' block. In a way, they use your own hashing power to fork you away... We continue to investigate possible such cases and will implement more protection in the wallet itself. But it is important to know, that an valid (i.e. not modified) wallet would not relay such blocks.

If you are not block generator, you can connect any way you wish, as long as you make sure you are connected to at least one of the 'good' nodes. You will eventually receive the 'cure' from the good node and heal automatically. This should require few hours at most.

Hope all this makes sense. I need to get better to be more concise, sorry

How do I fix my wallet.  It is showing difficulty 1.7?

Also Danbi's pool shows only 640067 blocks found but my wallet shows 640081 blocks?

update - nevermind  I followed the old instructions and updated my data now wallet seems to match Danbi's pool data.
