Hi, Just a heads up on the hosting for the Datacoin explorer on CryptoID, it will expire on 2019-08-02 00:00 (in 7.5 days). If your contribute towards the CryptoID hosting costs, the explorer for Datacoin will be hosted for longer https://chainz.cryptoid.info/contribute.dws?coin=dtcThank you, Hamburger

Hi, Please be advised that the domain datacoin.tk will most likely cease to exist or be removed from my control in 90 days time due to ongoing issues with the .tk registrar. This situation was partially resolved twelve months ago when I had an opportunity to move the domain name from the free space to a paid domain. Ever since then it became impossible to retain any of the domain names under my control. You are requested to move your coins from the online wallet https://www.datacoin.tk/wallet/ if you are one of the 129 account holder with a positive balance. The Datacoin node will remain online and will still be accessible via the IP address and therefore access to the online wallet accounts will also be available, however, that will be without SSL access. I will most likely make the online wallet available should a suitable domain name become available in the .org domain space - any suggestions are welcome. Thank you, Hamburger

Hi,
I am looking for a Miner that would be able to test a new version of an upgraded altcoin. The coin use the same algorithm as Litecoin (scrypt) with the difficulty mostly under 1.00 - Nvidia GeForce 1060 6GB mining is preferred, however, the Futurebit Moonlander 2 Scrypt Asic USB Miner may aslo be used. If this fail, any other means of mining on the new version will be appreciated.
Please send me a PM for the details or reply here if you want me to send you a pm with more details.
Tnx,
Hamburger

no active miner?
@QQ6693606 What do you mean with - no active miner? as all transactions are done without any issues? Hamburger

@superbotolo
Yes, not so much as the upload file size is limited, however, answer is still yes.
Yes, however, the uploaded file is compressed resulting in a smaller file but still each node will have to store all of the information on the block chain.
Yes and no, you need to encrypt and password protect your files before publication on the block chain if your require encryption and protection otherwise the file is accessible to anyone with the transaction id.
I am working on three things at this time, the first, to complete the in wallet block explorer provided by Graham Higgins. The second is an in wallet file publisher for publishing files on the block chain, keep a record of transactions id's of all published files from the wallet as well as transactions id's of third party files that was retrieved with the wallet and the retrieval system to download and decompress file for access. The last is similar to the the second, however, a web based system.

@igorttomic You are totally lost, this is Datacoin and not Datatoken.... H
|
|

I actually understand why we lost excellent coders for Datacoin!
Everyone wants top of the range software, applications and features, however, the very same people are the first to criticize, complain and whine about the development of Datacoin. None of these supporters or rather (ab)users are willing to put hand in pocket to support the coders nor are they willing to pay for private development of their requirements and then make it available to advance the development of Datacoin.
Anyway, let me leave it at that, I will reevaluate my position in three months time.

![Roll Eyes](https://bitcointalk.org/Smileys/default/rolleyes.gif) Crikey! forgot that YoBit have DateCoin (DTC) and DataCoin (DTCN) tokens, a good practice would be not to list tokens as coins! H

|

this coin is still alive?
Yes, why do you ask?
|
|

Is it possible to add to this wallet: http://www.datacoin.tk/wallet - function of uploading files, we can currently do it, but only with DTC Browser, which is inconvenient and impossible for mobile users? Dunno, how much effort it would need - DTC Browser is already working - but probably need some backend to do operations - https://github.com/j0nn9/DTCBrowser@muf18 It should not be to much effort to implement the publishing of files to the Datacoin blockchain, or I rather hope so! Anyway, the publishing of files to the Datacoin blockchain using PuTTY and WinSCP is easy if you run a node on DigitalOcean or Vultr. Just upload your file for publishing to any directory on the server i.e. /var/tmp/filename.txtNext login to the server with PuTTY and at the prompt type; bzip2 -c -9 /var/tmp/filename.txt | base64 -w 0 | xargs -I XX datacoind senddata XXand press enter. The successful publishing of the file to the Datacoin blockchain will return a transaction id (txid) i.e. 3cf7b2efc185cc948261abd3d5d633e9dd3878a8315d579a9ebfd76638638ac1To retrieve the publication, login to the server with PuTTY and at the prompt type; datacoind getrawtransaction 3cf7b2efc185cc948261abd3d5d633e9dd3878a8315d579a9ebfd76638638ac1 | xargs -I XX datacoind decoderawtransaction XX | grep -E '"data"' | grep -E -o ': ".*"' | sed -E 's/[": ]//g' | base64 -d | bzip2 -d > /var/tmp/retrieve_filename.txtThe successful retrieval of the file from the Datacoin blockchain will return no visible output, however, you will find the file at your location entererdi.e. /var/tmp/retrieve_filename.txtLike I said, easy, very easy! Now, I just recently started learning about executing a shell script from a PHP script and have not yet found a proper solution. If someone out there know how to execute a shell file I should be able to implement the publishing of files to the Datacoin blockchain on http://www.datacoin.tk/wallet i.e. getinfo.sh #!/bin/sh
// Returns an object containing various state info. datacoind getinfo that will return; { "version" : "v0.1.2.0dtc-hp11-unk-beta", "protocolversion" : 70001, "walletversion" : 60000, "balance" : 0.00000000, "blocks" : 2900817, "moneysupply" : 36483140.72783475, "timeoffset" : 0, "connections" : 23, "proxy" : "", "testnet" : false, "keypoololdest" : 1528975869, "keypoolsize" : 101, "paytxfee" : 0.00000000, "errors" : "" } Using a PHP file i.e. getinfo.php <?php
echo exec("bash shell.sh 2>&1");
?> or something like; <?php
$command = escapeshellcmd("bash shell.sh 2>&1"); $output = shell_exec($command); echo $output;
?> H

Welcome to the new year! Well that was a bit late for that but anyway, I found that https://www.blockexplorer.tk/ ( http://207.148.31.116/) are not working and at first left it at that. Later I decided to investigate as it is the only know blockexplorer for Krugercoin that I use to make sure my nodes are updating correctly. Eventually found that the free domain was suspended. Left it at hat again and then the flame started to burn again I then decided to approach freenom for an answer. It boils down to it that one of their trusted security partners decided to suspend the domain and no one are unable to provide any clear reason for this - see blow for reply; Thank you for your message.
Upon inspection, we have found that your domain name has been removed by one of our trusted security partners. Because we completely trust these companies and individuals (we wouldn't call them trusted partners if we didn't) and their reasons for removing domain names, we will not be able to restore the domain(s) to your account.
Possible reasons for having your domain name removed by our security partners include but are not limited to: - phishing; - spreading viruses and/or malware; - copyright infringement. These are violations of our terms and conditions that we do not allow.
Kind regards,
Freenom Support So now I have send them a reply, not that I expect that they will admit their failure, corruption, unethical, behavior etc.., I appreciate your reply, you should however seriously have a re look at your trusted security partner that suspended this domain as they are in the process of damaging your reputation. The website https://www.blockexplorer.tk are; 1) Is not a phishing site as it does not collect any user information nor does it send or receive emails as a matter of security and integrity for server safety. 2) Is not spreading viruses and/or malware as there are no interaction with any visitor nor does it contain any scripts or software that is capable of doing so. 3) Is not infringing on any copyright as for the code use on the site is open source and the deployment of the software on this server complies with the license agreement of the author. In addition, the name block explorer or blockexplorer are not copyright protected as it is commonly used by the crypto currency community and the phrase was coined by the original developer and visionary of Bitcoin. Furthermore, the service that run on this site is the block explorer for Krugercoin, a unique crypto currency and the name in it self also does not infringe on any copyright or trademark as most likely and erroneously contemplated by your trusted security partners. The copyright and trademark that they mostly think of is Kruger Rand that is the trademark of the South African Mint and copyright also vest in South African Mint - there are no trademark name or copyright known as Krugercoin. You really do not have to reinstate the domain as your supposedly trusted security partner is engaging in noncompetitive and corrupt behavior for suspending this domain and is depriving a small community of their right to identify with them self. My personal believe on this suspension is that it is politically an racially motivated and has nothing to do with any of the reason sited. I take it that you will understand that I will no longer be able to promote or recommend your services and will not proceed with my planned upgrading any of my other free domains to paid domains. Thank you, Sorry for any inconvenience this cause to anyone using the site - it is still available via the ip address http://207.148.31.116 ia any one need to access it. The krugercoin.tk are also removed and is now available as a "SPECIAL" domain at a premium. Anyway, lets see what the future hold and move to a better domain extension and registrar. H

Was the Krugercoin founded in South Africa?
Does it have any relation to the Kruger Park?
Louis, Unfortunately no on both counts - it was some guy from India who saw an opportunity to make some money, created the the coin and then dropped it like a hot potato when he though it reached the highest value. Fortunately there are a few people out there that still support the coin and is actively mining the coin to keep it alive. I still would like to see the coin succeed on such a level that it would be useful in South Africa. You would find some information at; https://web.archive.org/web/20140208001152/http://krugercoin.co/main/PM me if you want to work on this coin with me. H

Nice script! I would go with at least 1GB RAM, so it's not swapping to hell and back. I've had some odd experiences (like internal compiler errors, or signal 11 core dumps) when trying to compile coin daemons on a memory constrained VPS.
It is correct, this script is meant to be for Ubuntu 14.05 Desktop users that want to compile the Ubuntu Graphic User Interface - can be done on their own machine or virtual server. Compiling Windows Binaries on a machine with these specs will take most likely two days. I prefer 6 cpu /16 ram as it only take a few minutes to compile the Ubuntu Graphic User Interface and about 20 minutes to compile the Windows Binaries. Would be nice to know if this will work on the Windows Subsystem for Linux. H

Are you using the linux GUI wallet? If so what changes are needed to Hamburger's instructions given above to be able to compile the GUI version?
Or is there another way to install the linux GUI wallet?
This script will install and compile the Linux graphic user interface for krugercoin-qt You can build on a Virtual Private Server: Server:Ubuntu 14.04 x64 CPU: 1 vCore RAM: 512 MB Size: 20 GB SSD Referral link below - if you really appreciate open source http://www.vultr.com/?ref=7587570 - November only https://www.vultr.com/?ref=7225127 - Anytime - recommended The $3.50/mo [$0.005/h] server would be fine and it will take approximately 40 minutes to complete. 1) Create a shell file - install.sh Copy and paste: #!/bin/bash

You should know what to do if you are using Ubuntu Desktop. Some appreciation would be nice, just check out the nice Krugercoin address below!

I've compiled the daemon per the above instructions (thanks!) and I'm syncing now. I see 2 connections that have block height of 8877770.
45.32.163.218:8771 70.169.221.184:8771
Somebody must be mining on the v09.3 network.
edit: now I'm mining on the 9.3 network
Congrats on the mining - I naively believed that nodes are the back bone of maintaining any chain, after the fiasco of the last month, I now understand the symbiotic relationship between miners and nodes much better. You should do a short tutorial on mining and post it here for other people who are not willing to ask in the open - I can not keep up with the PM requests for assistance. I have asked https://www.atomminer.com/ to add Krugercoin to their pool - their FPGA Crypto Miner will support scryt mining and it would be ideal for mining Krugercoin. Very low power consumption and easy to maintain. BTW - they are looking for distributors if anyone is interested, just join them on Telegram 45.32.163.218:8771 is just a node running 0.9.3 and 70.169.221.184:8771 could be either an exchange or a miner. I have added the necessary check points up to block height 8800000 in 0.9.4 and will see how fast the synchronization is now. Tnx, H

what changes to the above are need to get the gui client to compile?
I unfortunately do not know - I make use of the command line only or Windows PC. Most likely you will have to include the qt dependencies, my development environment include; autoconf automake autotools-dev build-essential g++ git libboost-all-dev libczmq-dev libdb4.8++-dev libdb4.8-dev libevent-dev libgmp-dev libprotobuf-dev libqrencode-dev libqt4-dev libssl-dev libtool miniupnpc pkg-config protobuf-compiler python3 qt software-properties-common univalue unrar uuid-dev For Qt5 also install; libqt5gui5 libqt5core5 libqt5dbus5 qttools5-dev qttools5-dev-tools In most altcoins, the altcoin-qt for *nix will automatically build when you compile, provided that all the correct dependencies are met. I will try to do this once I have a stable chain to work with - It's been more than a month now since the mining stopped and the blockchain went out of sync. I will recompile the Krugercoin 0.9.4 client with check points to only follow the longest Krugercoin chain. At the same time, I will see if I can find a way to prevent Worldcoin, Digitalcoin and the rest of the Krugercoin and Litecoin clones that piggy back on Krugercoin to connect to the network. If all else fail, I'll either abandon the rescue of this project or create a hard fork. H
