[DeM] Deutsche eMark - DEM - cryptocoin SHA256 POS/POW

[Valkyrie Crypto Gaming]

Is anyone still running this or has it become an empty shell project?

I noticed the wallet has been slow to update for many months, has anyone fixed that with a latest release?

It was the latter long, long ago (like back when folks mostly used S7s to mine); literally no important code changes in nearly 3 years

I wonder why they decided to abandon ship.

Hi guys,

It's time to list DEM in new coin exchanges and rise the value to good price!

Where is this coin still traded?

Hi guys.

I've installed eMark-Qt on Mac, loaded blockchain, loaded backup of wallet.dat but wallet says 0 and out of sync.

Apologies if this question was asked before and answer, would appreciate link to the post.

Thanks

Probably can't find peers. (Does anyone know if there are DNS Seeders for DeM which track active nodes and can be queried for current peers on the network ?)

 It's been a long time since I looked into DeM, but if you give me the link for the eMark-Qt for Mac, I will install it and see if I can have it find peers and offer help and advice to you.

You can try going to http://blockexplorer.deutsche-emark.org/ and then click on the "Network" tab (on the top, third one from the left) and copy some of the IP's of peers on the eMark P2P network as "addnode=" instructions in the .conf file

These are some of the peers I found:

Code:

addnode=144.91.77.184
addnode=213.136.80.217
addnode=45.142.176.172
addnode=82.161.34.149
addnode=147.135.97.55
addnode=95.217.78.79
addnode=41.13.20.93

eMark Github updated to V1.6

https://github.com/emarkproject/eMark

This github's latest tag is v1.5.0
Is there another site that has v1.6 ?

I compiled and ran v1.5.0 (the latest on this repository) and monitored the debug.log output file.
It makes mention of a DNS seed

Code:

Loading addresses from DNS seeds (could take a while) 
1 addresses found from DNS seeds
dnsseed thread exit
connect() to 185.243.11.77:5556 failed after select(): Connection refused
connect() to 185.243.11.77:5556 failed after select(): Connection refused
connect() to 185.243.11.77:5556 failed after select(): Connection refused

but does not in fact connect to any peers; the reason is that line 94 of chainparams.cpp refers to a sub-domain of deutsche-emark.de which should be name-served by a delegated DNS server (the DNS seeder) running a customized version of Sipa's seeder,

Code:

 94         vSeeds.push_back(CDNSSeedData("deutsche-emark.de", "seed.deutsche-emark.de"));

this delegated name server for the sub-domain should return several IP's of real-time active nodes, but instead is just returning one IP
but which is not actually running an eMark node. Look at the ANSWER SECTION here:

Not until I added at-the-time known good peer nodes to the ~/.eMark/eMark.conf file were peers found

Thanks @Glen123New ... I do see that the node reports v1.6.0 when it runs, but for completeness, the  code on github ought to be tagged 1.6.0 to avoid any doubts.


Git supports two types of tags: lightweight and annotated. A lightweight tag is very much like a branch that doesn't change — it's just a pointer to a specific commit.

Annotated tags, have a bit more info and are stored as full objects in the Git database. They’re checksummed; contain the tagger name, e-mail, and date; have a tagging message; and can be signed and verified with GNU Privacy Guard (GPG). It’s generally recommended that you create annotated tags so you can have all this information.

Creating an annotated tag in Git is simple. The easiest way is to specify -a when you run the tag command:

Code:

$ git tag -a 1.6.0 -m 'version 1.6.0'

Currently, when you check tags on the source code, its seems like the latest version is 1.5.0

Code:

/usr/local/src/eMark# git tag
1.0.0
1.1.0
1.2.0
1.2.1
1.3.0
1.4
1.4.1
1.5.0

The latest Release on github is also "eMark v1.5.0"

I've set up two DNS Seeders for Deutsche eMark and compiled binaries for Debian 10 "Buster" and  Ubuntu 16 "Xenial Xerus",  18 "Bionic Beaver" & Ubuntu 20 "Focal Fossa".
The DNS Seeders track active nodes on the network in real time, and when queried, give a list of eMark node IP addresses that are ready to receive peer connections and judged to be of high quality. This should help alot in getting initial sync and connections to peers:
 
The sub-domains:

dnsseed.deutsche-emark.cc
dnsseed.emarks.cc

They can be independently queried via the web at these links:

https://deutsche-emark.cc/emark-nodes.php
https://emarks.cc/emark-nodes.php

Example command-line query using dig in Linux:

Code:

dbkeys@zuhause:~$ dig dnsseed.deutsche-emark.cc

Similar queries can be done in Windows with nslookup

I use Windows 7 and 10, and a lot of Debian 9 and 10 on laptops and on my other 10-15 computers I have at home. No Ubuntu though, but if the glibc and other things are the same version...

But I prefer a QT-gui from console Linux when doing coins.

I checked, and the libraries are a mis-match between Debian & Ubuntu, so I got a VPS and made a binary specifically for Debian 10:

Debian 10 "Buster"

and a Qt GUI  too
Debian 10 "Buster" QT GUI Wallet

Let me know how the Qt works out for you

dbkey, thank you very much for yout work. Do you think your dnsseeder domain is permanent? Our seeder work here: 46.232.249.107 but there are problems with the DNS configs on NETCUP.
If your seeder is permanent i can talk with Rumhoker that he insert your seed domain in the source.

Hi Fyuri,  yes, its my intention to maintain the domains & node tracker/seeders running on a long-term basis, the same with the three static nodes. I will keep them online going forward, so it would be great if they were put in the official release.
