DEM wallet at crypsty  why is still im out

@phatkiller  thx for great info phat. After I saw your post I thought maybe I should get my couple miners out and give it a try. I gave werming pool  a try, got lucky and found a block. I was the only miner there lol. Immer gerade aus   always going straight ahead.

PS: I'm staking later today and will transmit some thankfulness to your address 

no, the nethashrate is not necessary for building a new block and is not known.


Yes, the difficulty is given in the last block for the next block and fix for the next 2 minutes.
The nethashrate is calculated from the difficulty.

estimated hash rate ≈ Difficulty * 4295032833.0 / 120
if Diff = 1000000 ->  Nethashrate ≈ 35 THs 

BUT THIS IS ONLY FOR POW WITHOUT POS

POS coins has a less mininghashrate by miners, (eMark at this time ca. 1/5)
eMark calculate the nethashrate like Novacoin.
https://github.com/novacoin-project/novacoin/blob/master/src/rpcblockchain.cpp#L50
I think this would be the best way to estimate the hashrate.

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.

have a nice day

DEM Pool List

http://coinz.at/DEM/
Currently down usually has highest Hashrate of the publicly available pools. I've mined ~100 DEM here.

http://dem.suprnova.cc
Good pool sitting at about 3 - 5 th/s right now.  I've mined about ~1000 DEM here.

http://dem.gcpool.eu
Haven't had the chance to mine here yet low hashrate right around 400 gh/s right now. I think glen123 owns this pool.

http://miner-control.de:8000
This is where I've mined most of my DEM (~5500 DEM) usually sits between 3 - 5 th/s

http://mining.securepayment.cc/pools/emark/
This is a pooled SOLO mine.  Basically if you discover the block you receive full reward minus 3% fee I mined exactly 3 blocks for a total of 145.5 DEM

http://dem.werming.com/
Haven't had the chance to mine here yet low hashrate right around 1 gh/s right now.

http://dem.ispace.co.uk/coindetails/?coin=dem
Great pooled I've mined a few coins on here.

There used to be two others but i think they are gone if i find the URLs i'll post em.

Market List

https://www.cryptsy.com/markets/view/DEM_BTC

Mixed feelings about cryptsy.  I love that they support so many altcoins but this wallet has been in maintenance forever.  They've even stopped
making excuses as to why the wallet isn't working all they say now is that its in maintenance.

https://www.cryptopia.co.nz/Exchange?market=DEM_BTC
Low volume, I've succesfully traded on here without a problem cant complain about the exchange side of things but as far as the mining side ........

https://yobit.net/en/trade/DEM/BTC
Just recently added DEM.  Never traded on here

Final market is coins-e I wont provide link DO NOT trade there as they are holding 7k+ DEM of mine hostage and refuse to release it or even respond in a timely fashion to my emails/support tickets.

In general, pools know their own hashrate quite accurately. I don't know exactly how the DEM core software is calculating the net-hash-rate, but it must be using a certain number "x" of blocks (would have to look at the code to see what "x" is) to determine an ellapsed time which it uses to derive the net-hash-rate over that period of time.
In reality, over any length of time the actual hash rate powering the network can vary up or down very substantially, so that at any particular point in time, the real number of hashes-per-second can be quite different than the number reported as net-hash-rate by the DEM core software (wallet).
So it's not surprising that a pool might know itself to have a higher hash rate than the total net-hash-rate _reported_ by the core software.

You could think of it this way: the pool reports its own instantaneous hash rate, and the wallet reports the average net-hash-rate over a longer period of time.  So the instantaneous hash rate of a pool could exceed the net-hash-rate reported by the DEM core wallet, particularly if a few large rigs very recently joined the pool.

If those rigs stay on the DEM network, eventually the core DEM wallet will reflect that increased hash rate too, but it will lag the pool's knowledge; the pool is the first to know about increased hash rate, because it actually has to give work to the miners; the DEM wallet is only aware of blocks being found, and once the blocks are found then it can calculate how much hashrate was on the network to account for the blocks found over that period of time.

please read this for bitcoin hashrate
https://en.bitcoin.it/wiki/Difficulty


estimated hash rate = Difficulty * 4295032833.0 / 600
Difficulty = 600 / 4295032833.0 * estimated hash rate (hash/s)

eMark have 120s Block time. So change 600 to 120 and test

just to inform :

working on pool. restart in est . 1 h

Coinz.at is deceased (DEAD) for a couple of days

Just again for info



here are three mining pools (with my comments)




coinz.at                            pool very stable but sometimes web-interface is slow (sometimes not available for days !!)
                                       ----> the most miners

dem.suprnova.cc                pool very stable and responsive 
                                       ----> only a few miners

dem.gcpool.eu                    small pool very stable very responsive admin (sometimes a lot orphan blocks --> under investigation)
                                        ----> only one or two miners

with the  parameter : "load-balance" : true, in cgminer.conf you can send shares to all at the same time with one miner.
if one pool fails, this part will switch to the remaining pools.

Have a nice day

yes that works fine - sent a bit of hash as a test - all good


Cheers - usukan

aha - cool thanks

am I blind or missing something - can't find DEM here?

will change from 30 to 120

just making backup and recompile


gimme a sec

You are right, i think i made a mistake.
i will take a look at it on weekend.

OP of threat says this:

1.
create a new file „emark.conf“ with edior and save it at "all files" to be named correctly (not .txt at the end)
Drag or Copy&Paste in the file:
Code:
server=1
rpcuser=USERNAME
rpcpassword=PASSWORD
rpcallowip=127.0.0.1
rpcport=6666
USERNAME and PASSWORD should be replaced as your needs
There should the file go in:
%\AppData\Roaming\eMark

2.
as before, you should create a new file in the folder of your wallet: eMark-qt-server.bat
Drag or Copy&Paste in the file:
Code:
emark-qt.exe -server

3. create a new file in the folder of cgminer and name it "runme.bat (or as you wish)
Drag or Copy&Paste in the file:
Code:
cgminer.exe -o http://127.0.0.1:6666 -u USERNAME -p PASSWORD
USERNAME and PASSWORD should be replaced with settings of „emark.conf“

4. now, you can start solomining:
start file eMark-qt-server.bat
start CGMINER with runme.bat

Now, thats all - you can start mining the "Deutsche eMark"


EDIT: just tried this and it don't work. Tried to change IP in conf file and in Cgminer of ASIC. Also don't work. In ASIC I changed IP of computer where wallet is, and in conf file I changes IP of ASIC

where is link for Solo asic minning config?   need help

Ok thanks
