i think we need to offer something only for DEM
There is an online shop with DEM. But no real goods. If you buy something nobody will ship you the goods.

http://shop.deutsche-emark.org/
OK, it is not a pretty layout but work.

If someone have something to sell i can give acces to the shop.


what about selling used MinerHardware ?


i got 1 1 THS  and 1 260 ghs SHA Miner ( A1 Chips )

only 0.88 BTC is needed to hit the price of 0.000012 on cryptsy which is mining price of DEM atm. And you will get 74000 DEM for 0.88 BTC

i think we need to offer something only for DEM   like  Brand New  BMW Smiley  only for DEM

and here is my offer:

if someone buy TODAY on Cryptsy -Sell orders up to price 0.000014 (right now is this 107K dem= cc 1.5BTC)  i give to him my reward 10k DEM

but first you have to send me PM with Cryptsy Trade key to transfer 10k Smiley

Hi

i open a ticket at Cryptopia

--------------------------------------------------------
Hi,  would you please so kind to include a new Edem-Pool (Deutsche Emark) in your Mineshaft. I would really mine and trade at your side!  Have a nice day
--------------------------------------------------------

Answer:

-------------------------------------------------------
Hi,  We used to have one but for some reason it was incompatible with our pool software and we could never find the issue, it would never solve a block no matter how much hash we used.  The decision was made to remove the pool as a lot of users were unhappy about the wasted hash.   We are sorry about this but there is not much we can do at this time.   Thanks
------------------------------------------------------

And i wrote an email to coinwarz:

----------------------------------------------------------
http://www.coinwarz.com/cryptocurrency/coins/emark
----------------------------------------------------------

to update there information there (i put all information in the email)

so everyone could calculate again if its worthy to mine DEM  ex.:

Have a nice day



The answer :
--------------------------------------
Hello,

If Cryptsy takes DEM out of maintenance so mined coins could be exchanged, then we would consider re-listing DEM.

So we are still stucked on Cryptsy  Cry

Write then again now

Mail is on the way!

Have a nice day!

cryptsy wallet back online, now it's time to rise

thats awesome...


where you can get wallet version eMark:1.3.2
??

compile yourself from github.
i can make a win wallet, but it is not necessary. In V 1.3.2 i only have add RPC command "getnetworkhashps"


Yobit.net give free DEM:

people buy DEM now. now is the time to rise the price. buy while it's cheap. I bought DEM today for 2 BTC. Buy now or you will be sorry later. Mining costs are around 0.00001 so the price should follow.

EDIT: price on cryptsy is now 0.00001

just for testing i pointed around 11THS to Pool

pool got more hash than nethash

testing with my winwallet (newest ) give me :

"currentblocktx" : 0,
"difficulty" : {
"proof-of-work" : 1580956.04153786,

really seems problem of wallet 1.3.x to measure real nethash

edit : nethash stable since 10 Blocks

dbkeys: Thanks for the good explanation of hashrate and difficulty.

The problem is the POS. If the wallet find more POS blocks, the POW diff will rise up. But the POW hashrate remains the same. The old 1.1 wallet now show more networkhash, because it calculate the networkhashrate like bitcoin.
In V1.3 i have change the hashcalculation like Novacoin use. Is is much more accurate.



I agree with this but :

If i can see the hashrate of three different pools (the hashrate of the miners) and i can tell these hashrate are ok (because the hashrate of my miners is shown correctly)
and one given pool has more hashrate (from his miners) as the fourth pool (with the new wallet) show as nethashrate Huh?

example (by heart)

Pool 1 = 6Thashes and i can see it is correct because my miner show the exact hashrate as shown in this pool
Pool 2 = 2Thashes and i can see it is correct because my miner show the exact hashrate as shown in this pool
Pool 3 = 1.5Thashes and i can see it is correct because my miner show the exact hashrate as shown in this pool
(because my miners are mining in all pools)

All of this pools show the same nethashrate as 53Thashes

Pool 4 (new wallet) = 0.7Thashes and i can see it is correct because my miner show the exact hashrate as shown in this pool
shows only 5.3Thashes as the Nethashrate...........this is less than pool 1 has Thashes from his miners
even without Pool 2 and Pool 3

At the Moment:

Pool 1:   5.5 Thashes
Pool 2:   1.3 Thashes
Pool 3:   3.36 Thashes

Pool 4:    0.24 Thashes Nethashrate 8.59 Thashes Huh??

It's true that my comments apply to a pure POW coin. Since DEM became a hybrid POW / POS, I assume more blocks will be found than would have been the case purely from POW.
Also, ¿ was there was a change in how the core software calculates network hashrate from the old wallet to the new one ?  If so, then it makes no sense to compare these two numbers.

Hi

i found this ..... (with my comments in red)

----------------------------------schnipp----------------------------------------
So, to calculate the average hashrate for a given period, simply:

1) Take the total number of blocks generated for that period (for DEM should be a block every 2 minutes otherwise the difficulty will change in a predifined time)

2) Muliply it by the total number of hash possibilities (2^256 for a 256 bit hash)

3) Divide it by the number of hashes that would be considered "valid" for a block (the target hash value)

The number of valid hashes can be calculated from the difficulty (which should be the same like it mentioned in point 1), which is something that is coded into the protocol.
A good place to start to find out how difficulty is transformed into a target hash value would be: https://github.com/bitcoin/bitcoin/blob/ca1913e8f64fc245157b008d6b37160306aa1d83/src/miner.cpp
Just search for "target".

So every time a block is found (and this should be around 2 minutes) and the difficulty is not changed i can calculate very accurate the nethashrate.
How accurate and how responsive   this calculation is   due to hooping miners (with high hashrates) depends of the length of the period you choose for the calculation.

Just in mind only valid for POW-Coins

Back to the problem:
If i find 3 pools telling me the net hashrate is  39 Thashes (at a given time and all with the same number)
One pool has 1 Thash
second has 4 Thash
third has 8 Thash

and a fourth  pool has 0,5 Thash and telling me the nethashrate is only 6 Thash
there should be something wrong with that pool.
15 Minutes later the numbers changed but in the same relations.

Keep in mind the first three pools are using the old DEM-Wallet and the fourth pool the new DEM-Wallet

Have a nice day

The Block time is 2 minutes ! So every 2 minutes the chain (for all on the right branch)is synced. So it is clear to me that every 2 minutes the nethashrate is known to everybody synced to the chain (who is not will geht the next block an orphan block).
Because the difficulty is dependent to the nethashrate (blocks have to be finished max every 2 minutes) the nethashrate has to be known to everybody working on the blockchain.

The block time is only a _target_ block time, it's what we want to achieve, on average. But achieving the desired difficulty target with a hashing function is a Poisson random process, which means you might find the desired result in less time or more time than the desired 2 minutes. Only if hashrate and difficulty are well matched, then, in the long run the average of the block times will be 2 minutes.

In a pure POW coin (like Bitcoin for example), difficulty adjust every so many blocks. (In bitcoins, its every 2016  blocks; if blocks come out ona average every 10 minutes, that will be 2 weeks). But if  blocks have been coming out faster than every 10 minutes, then difficulty will be increased by the difficulty adjustment algorithm to slow down the rate of production. If it took longer than 2 weeks to validate the 2016 blocks then difficulty will be lowered to speed up production.

No coin controls its network hashrate (Just look at the problem of multipools suddenly joining and then leaving coin networks). The network hash rate depends on who is mining and how powerful their mining equipment is. People can point their mining rigs at a different coin in an instant!
The only thing a coin network can set and control is the difficulty factor. Most POW coins have switched to much more responsive algorithms to adjust for more drastic hash rate variations than the original bitcoin algorithm could ever handle. (These algos go by names like Kimoto's Gravity Well, Dark Gravity Wave, DigiShield, Delta, etc.) So the difficulty factor is adjusted in these newer algos sometimes as often as every block, but it is always the difficulty factor being set in response to the observed hashrate.

The equation governing this relationship is:

     Hash Rate (hashes / second) = Difficulty (hashes / nonce) x [blocks_found / blocks_expected] x [size of nonce space (nonces) / target block time (seconds) ]

The size of nonce space is 2^32 = 4 294 967 296 (nonces) and target block time for DEM is 120 seconds, to equal DEM's Constant
C = 35 791 394. 13 (nonces/ second) or as Rumhocker says, about 35.8 MegaNonces/second

So let's say a real time hour has gone by, and only 20 DEM blocks have been found in that hour. If the difficulty factor has remained constant during this time, then the Hash Rate can be found with the above equation. Once you know the "effective" hash rate for this hour-long period, then you can use it to set what will be a correct difficulty factor to match the observed hash rate.

For a concrete example, POW difficulty on DEM is now:  1 673 882.67  (hashes/nonce)
If we apply this to the above hypothetical situation,
1 673 882 .67 (hashes / nonce) x [20/30] x 35 791 394 .13 (nonces/ second) = 39 . 940 396 Tera Hashes / Second
Once you know this "effective" hash rate during that hour, now you can find the difficulty factor that will balance this hashrate to produce, on average, a 2 minute block time. (Note that since we want blocks_found = blocks_expected, so that term = 1)
39.94 (TH/s) / 35.8 MegaNonces/second = 1 115 642.4 (hashes / nonce)
Which makes sense ... the difficulty is lowered, because too few blocks were found.
