Storage space: I am using an 8 GB microSD card for the OS, and a 128 GB USB drive for data. Minimums I would recommend: 8GB SD card and 32 GB USB drive.
Reddcoin Core client version: v18.104.22.168-a8767ba-beta (most recent version at this moment). ↳ Screenshot
You need the OS; Lubuntu. Download Lubuntu (707 MB) for the Raspberry Pi: https://ubuntu-pi-flavour-maker.org/download/. It's a .torrent download, so you will need a BitTorrent client. Message me or post in this thread if you need help with this.
You need software to write the OS to the SD card. I use Etcher. Download Etcher: https://etcher.io/.
Select image: select the lubuntu-16.04.2-desktop-armhf-raspberry-pi.img.xz file.
Select drive: select your microSD card.
Plug the SD card into your Raspberry Pi and power it up.
Lubuntu should boot up.
Set up Lubuntu, connect to the internet (wired or wireless). ↳ As username, I chose "rpi3b". You will see this username throughout this whole tutorial.
Make sure date and time are correct ([Menu] > System Tools > Time and Date). ↳ Click on Unlock to make changes. I personally change Configuration to "Keep synchronized with Internet servers". ↳ Screenshot
Reboot ([Menu] > Logout > Reboot). I am connected to wifi, but have issues getting wifi to work on initial boot. A reboot solves this issue.
Make sure system is up-to-date, install never versions.
Open LXTerminal ([Menu] > System Tools > LXTerminal). ↳ Screenshot
Enter the following in LXTerminal: sudo apt update && sudo apt upgrade ↳ Screenshot
You will be asked if you really want to continue. Enter Y (yes).
Updates are being installed! Wait until it's finished.
Install programs that will be used in this tutorial.
GParted: to partition the USB drive.
Htop: to see the amount of memory (RAM) and swap that is in use.
Enter the following in LXTerminal to install these 2 programs. sudo apt install gparted && sudo apt install htop ↳ Screenshot
Create 2 partitions on the USB drive: 1) Swap partition 2) data partition (for the Reddcoin blockchain) The swap partition is necessary: The Reddcoin wallet can be memory intensive. To prevent any crashes or freezes, add 2 GB of 'virtual' memory by creating a swap partition.
Important: Backup your USB drive if needed. The USB drive will be formatted, so the data on the USB drive will be wiped.
Please use the USB drive solely for this purpose, do not combine it with other stuff.
Keep your USB drive plugged in, do not (randomly) plug it out.
Plug your USB drive in.
GParted will be used to create the partititons. Start GParted via LXTerminal: sudo gparted ↳ Screenshot
Apply the changes. Click on the check mark or select Edit > Apply All Operations. ↳ Screenshot ↳ Screenshot
Important: The name of the swap partition is needed later, so please write it down. Mine is /dev/sda1 (first partition on first drive (drive 'a')). ↳ Screenshot
Reboot. After the reboot, the data partition you just created should be visible on your desktop. ↳ Screenshot
The swap partition is created, so now we can enable and use it.
The swap in use can be monitored with the program Htop. Open Htop ([Menu] > System Tools > Htop) to see the 'Swp' (swap) in use. ↳ Screenshot By default, swap is not used, so 0K. ↳ Screenshot You can leave Htop open.
To enable the swap partition, open LXTerminal and enter the following commands: (Assuming /dev/sda1 is your swap partition.)
Unpack the file (large file, takes around 15 minutes to unpack): sudo xz -d bootstrap.dat.xz ↳ Screenshot
After a successful unpack, your will find the file bootstrap.dat in your USB root folder. ↳ Screenshot
On the first run of the Reddcoin Core client, it will ask for a data directory to store the blockchain and wallet data.
Start the Reddcoin Core client: sudo /media/rpi3b/usb/reddcoin/src/qt/reddcoin-qt ↳ Screenshot
The welcome screen will appear and ask you about the data directory. I suggest a new folder on your USB drive, I picked blockchain. The directory will be created with all the necessary files. ↳ Screenshot
Click on the three dots (...) on the right. ↳ Screenshot
Click on Create Folder at the upper right corner. Type and enter in the folder name. (In my case: blockchain.) Click on Open. ↳ Screenshot ↳ Screenshot ↳ Screenshot
After selecting the directory, the Reddcoin Core client will start. Wait till it's fully loaded and close it.
Move the bootstrap.dat file to your data directory you selected in the previous step. By doing this, Reddcoin Core will use the bootstrap.dat file to import the blockchain, which speeds up syncing. sudo mv bootstrap.dat /media/rpi3b/usb/blockchain/ (Assuming blockchain as data directory.) ↳ Screenshot
The Reddcoin Core client set up is completed, but you still have to sync fully with the blockchain before you can send, receive and stake.
Keep the client running until it's fully synchronized. It will use the bootstrap file first, and download the rest of the blockchain to complete the sync. This can take some time (it took 2 days for me). Syncing the blockchain uses a lot of resources, so the software may react slow.
You can see the progress in the debug window (Help > Debug window). ↳ Screenshot
When the synchronization is completed, the red (out of sync) will disappear on the Overview screen! ↳ Screenshot
When synchronization is complete, you can start staking your Reddcoins.
You can write down your private key or copy and save it in a document. Make sure you save it somewhere only you can access it.
To import later: Debug window -> Console -> importprivkey [label] [label] is optional. ↳ Screenshot (without a label) ↳ Screenshot (with a label)
Boot with only 1 USB drive plugged in: Make sure only the USB drive (with the swap partition and data partition) is plugged in when you boot up your Raspberry Pi. This to make sure the swap partition (/dev/sda1) is recognized correctly. If you boot up with multiple USB drives, Lubuntu might see the USB drive with the swap partition as the second drive (instead of the first drive), and ignore the 2 GB swap partition. If this happens, starting Reddcoin can render the Raspberry Pi unresponsive.
Start Reddcoin Core easier Run a shell script (.sh file), so you can start Reddcoin just by double clicking on an icon on your Desktop.
Right Click on your Desktop and select Create New -> Empty File. ↳ Screenshot
Enter a file name, make sure it ends with .sh, and click on OK. I've chosen for Reddcoin.sh. ↳ Screenshot The file will be created on your Desktop. ↳ Screenshot
Add the command to start Reddcoin to the file.
Right click on the file, select Leafpad (to open the file in a text editor). ↳ Screenshot
Add the following to the file and save the file: sudo /media/rpi3b/usb/reddcoin/src/qt/reddcoin-qt ↳ Screenshot
To be able to execute the shell script (.sh), it has to have 'execute permissions'.
Right click on the file, and select Properties. ↳ Screenshot
Click on the Permissions tab.
For Execute, select Anyone, and click on OK. ↳ Screenshot
To start Reddcoin Core, double click on the file. A new window will pop-up, asking you what you want. Execute in Terminal is what we want, so you can click on enter. ↳ Screenshot Reddcoin Core will now start. Do not close the Terminal window, you can minimize it if needed.
Minimization options Adjust minimization options, so you can safely press on the X button (the close/exit button on the upper right corner).
Activate 'Minimize on close'. Settings -> Options... -> Window (tab) -> Minimize on close. ↳ Screenshot Reddcoin will still run when you click on the X button. To close/exit Reddcoin, right click on the Reddcoin icon in the system tray (bottom right corner). ↳ Screenshot
RealVNC VNC Viewer (client) and VNC Connect (server): To remote connect to the Raspberry Pi, I use VNC Viewer ad VNC Connect from RealVNC.
After your download is finished, open the file and click Install Package. ↳ Screenshot
To run the VNC Connect once:
Open [Menu] > Run, and enter: vncserver-x11 ↳ Screenshot
To auto run on startup:
Open Default applications for LXSession ([Menu] > Preferences > Default applications for LXSession). ↳ Screenshot
In LXSessions configuration, select Autostart in the menu left.
Under Manual autostarted applications, enter vncserver-x11 and click on + Add. ↳ Screenshot ↳ Screenshot
Reboot your Raspberry Pi and check if VNC Connect is started automatically after the reboot.
When VNC Connect is running, you'll see a VNC icon on the right bottom corner. Double click the icon to open VNC Connect and to see the IP address you need to enter to connect to your Raspberry Pi. ↳ Screenshot
I want to stake Reddcoins on my Raspberry Pi, but there is no easy to install package for the Reddcoin Core client. I found some tutorials (mentioned at the bottom, under 'credits'), but I still struggled to get the result I wanted. It took some small adjustments, but I got the GUI Wallet of Reddcoin Core working on my Raspberry Pi Model 3B. See the steps below. :).
If you have any questions or comments, please post a comment in this thread, so others can also benefit from it.
If you would like to tip me: RqvdnNX5MTam855Y2Vudv7yVgtXdcYaQAW.
Even though Raspbian is the primary OS for the Raspberry Pi, it seems that it's not possible to build and compile the Reddcoin wallet software for Raspbian Stretch. However, I got the wallet compiled using Ubuntu MATE.
RPi: Raspberry Pi 3 Model B
OS: Ubuntu MATE 16.04.2 (Xenial)
Space needed: I would recommend at least 32 GB. I am using an 8 GB SD card for the OS, and a 128 GB USB drive for data.
The Reddcoin wallet can be memory intensive. To prevent any crashes or freezes, add 1 GB of 'virtual' memory by creating a swap file. After your Raspberry Pi has rebooted, open MATE Terminal again and enter the following commands:
sudo fallocate -l 1G /swapfile
sudo chmod 600 /swapfile
sudo mkswap /swapfile
sudo swapon /swapfile
To make sure the swap file persistent (so it survives a reboot), you have to add a line to the /etc/fstab file.
In MATE Terminal, enter the following command to open the file in Pluma (text editor): sudo pluma /etc/fstab
In Pluma, create a new line, add this text: /swapfile none swap sw 0 0 ↳ Screenshot (You should add spaces to vertically align the lines.)
Save and close the file.
Back to MATE Terminal; reboot your Pi: sudo reboot
To see if the swap file is used after a reboot, run: sudo cat /proc/swaps ↳ Screenshot
After the reboot, open MATE Terminal again. Download, unpack, configure, build and install Berkeley DB:
Add this line in Pluma: /uslocal/BerkeleyDB.4.8/lib/ ↳ Screenshot
Save and close the file.
Back in MATE Terminal: sudo ldconfig
Download the source of the Reddcoin wallet and build it:
git clone https://github.com/joroob/reddcoin
sudo ./configure --disable-tests
sudo make ↳ Screenshot (this will take some time; with me it took just over 1 hour)
sudo make install
Speed up synchronizing with the Reddcoin blockchain by bootstrapping.
cd (to make sure your working directory is your home directory)
Download the bootstrap file (1.45 GB): sudo wget https://github.com/reddcoin-project/reddcoin/releases/download/v22.214.171.124/bootstrap.dat.xz
Unpack the file: xz -d bootstrap.dat.xz
After a successful unpack, your will find the file ''bootstrap.dat'' in your home folder. ↳ Screenshot
On the first run of the Reddcoin Core client, it will ask for a data directory to store the blockchain and wallet data.
Start the Reddcoin Core client: sudo $HOME/reddcoin/src/qt/reddcoin-qt
The welcome screen will appear and ask you about the data directory. I suggest a new directory in your home directory, I picked 'blockchain'. The directory will be created with all the necessary files. ↳ Screenshot
After selecting the directory, the Reddcoin Core client will start. Wait till it's fully loaded and close it.
Use the file manager (Caja) to browse to your home directory and move the ''bootstrap.dat'' file to your data directory you selected in the previous step. Your home directory is the first item in the File Manager in the left menu.
The Reddit Core client set up is completed, but you still have to sync fully with the blockchain before you can send, receive and stake.
Launch the Reddcoin Core client again: sudo $HOME/reddcoin/src/qt/reddcoin-qt
Keep the client running until it's fully synchronized. This can take some time (it took 2 days for me).
You can see the progress in the debug window (Help > Debug window). ↳ Screenshot
When the synchronization is completed, the red (out of sync) will disappear on the Overview screen!
Your wallet will be encrypted, and the Reddcoin Core client will be closed. Launch the Reddcore Client again. ↳ Screenshot 4
To stake, you need to unlock your wallet (by entering your password): Settings > Unlock Wallet...
Make sure "For staking only" is checked before clicking OK. ↳ Screenshot
You can only stake with Reddcoins that have matured: coins have to be at least 8 hours in your wallet to mature.
The grey arrow at the bottom should be green when staking. Hover over that icon to see the progress of staking. ↳ Screenshot
Backup your wallet! File > Backup wallet... ↳ Screenshot
Start Reddit on system login. Settings > Options ↳ Screenshot > This works when using only an SD card. > I can't get this to work when using SD card (for OS) and a USB (for data/blockchain).
Adjust minimization options, so you can safely press on the red X (close/exit button). ↳ Screenshot
The default browser, Firefox, stops working and crashes after updating Ubuntu MATE. My solution is installing another browser: Chromium. To install Chromium, enter the following in MATE Terminal: sudo apt-get install chromium-browser ↳ Screenshot You can then access Chromium via [Menu] Applications > Internet. ↳ Screenshot
To remote connect to the Raspberry Pi, I use VNC Connect from RealVNC.

[Guide] No hardware to mine? How to net 6,000+Ð/day using Windows Azure
Inspired by lleti 's free guide for using Amazon Web Services. However, from what I understand due to rental costs, it is more efficient to buy doge directly than use AWS. This guide is based on utilizing the $200 credit that comes with the Windows Azure cloud computing free trial, so you will not pay anything. This is targeted at shibes with poor hardware that can only mine 50-200 doge per day, but it will work for everyone. Disclaimer: Doge rate is an estimate based on current difficulties and market. Windows Azure trial may be US only (?) Overview / How it works You will not be mining doge directly with this method. Mining doge effeciently requires a GPU, which aren't found in traditional servers. Instead, we will be using the powerful CPUs provided with Windows Azure servers to mine a CPU based crypto-currency, such as QuarkCoin or SecureCoin, and convert those to doge. Steps 1) Install your QRK or SRC wallet Ideally if you are reading this, you have installed a dogecoin-qt wallet for yourself before. We will need to do the same for either QuarkCoin or SecureCoin. This is the wallet where will will send the coins you mine with your Windows Azure servers.
These are not the only CPU coin options, but QRK and SRC are very similar (same hash function) and simple to mine. Once you have installed the wallet, it should look very similar to your DogeCoin wallet. If you have trouble downloading the blockchain ('out of sync'), look at thesethreads respectively to see which nodes you need to add to your config file. Config files are located at C:\Users\UserName\AppData\Roaming\CoinName.conf on Windows. 2) Set up a mining pool account If you have joined a mining pool for DogeCoin, it will be a very similar experience for other alt coins. See the following bitcointalk threads which have a list of mining pools:
If you would like a pool recommendation, I can recommend src.coinmine.pl and qrk.coinmine.pl; this is from personal experience, I am not affiliated with them. Once you are logged in you should also create 3 workers, as we will be setting up 3 servers, one for each server. So you should have 3 worker names, and a password set up for each worker. 3) Sign up for Windows Azure free trial Link: www.windowsazure.com/en-us/pricing/free-trial/ You will have to provide a valid credit card and verify your account with a cell phone so they know you are a real person. This is a Microsoft product so they are reputable. Once you sign up, you will receive a $200 to use in 30 days. Remember to cancel when your credits are running out so they don't charge you. 4) Create Windows Server instances I would recommend you watch this video which walks you through the UI of the Windows Azure management site to set up the virtual machines we need. Essentially we are going to do the following:
Create 2 Windows Server 2008 R2 SP1 instances with 8 CPU core / 14 GB RAM option
Create 1 Windows Server 2008 R2 SP1 instance with 4 CPU core / 7 GB RAM option
Thus we have a total of 20 CPU cores to mine QRK / SRC with. We want the the most CPU power we can get without excessively burning our $200 credit. That's why 2008 R2 is used, and only 3 instances of it. 5) Remotely connect to servers and download miner This section is also covered in the video from section 4, watch it for a visual walkthrough. Once the servers have been initialized on Microsoft's end, we should be able to access them under 'Virtual Machines' at www.manage.windowsazure.com. You should see each host name and a status, and when selected there should be an additional 'Connect' button - click it. You should now be prompted to download a .rdp file. Download this for each of your 3 virtual machines to a folder you will remember. You will open this .rdp file and use the login credentials you previously specified to connect to each server. Once you are remotely connected, you should see the desktop. Open up the first icon on the taskbar that looks like a server, this is your server manager. We need to open up the 'Configure IE ESC' setting that's visible on this pane. Make sure 'Off' is selected for both admins and users on the IE ESC configuration. Now, open up the IE browser and navigate to https://docs.google.com/file/d/0B9cvOfoOekSdVzZZcThLZHg4bjA/edit. Press Ctrl + S to download the entire zip to the desktop, and un-zip it. 6) Configure and start miner Again, this is pretty much covered in the video from section 4, if you prefer watching. You should now have a folder on your server's desktop named quark-v2_w64. This is the miner for both QRK and SRC. We are going to be using minerd64_sse4.exe. Create a shortcut to minerd64_sse4.exe within the same folder. We now need to add the parameters for your miner. Right click on your minerd64_sse4.exe shortcut -> Properties. Look at the target field, it should look like this:
We are going append the following format to this target field
-a quark -t 8 -o stratum+tcp://src.coinmine.pl:6020 -u user.worker -p password
-a: algorithm, both SRC and QRK use 'quark' -t: number of cores (so either 8 or 4 for our purposes) -o: mining pool information (url and port). -u: account you have for your mining pool, then a period, then a worker name -p: password that you created for the worker in step 2 So here is an example of what the target field of your shortcut should look like when you are done:
7) Profit!! If you set up your miners correctly on each Windows Server VM (I prefer to assign a separate worker to each one), you should be able to run them and see an output like this: http://i.imgur.com/3lECqSz.png. You can close your remote sessions without interrupting it. How do you get the doge, you ask? Well, using the above setup I have earned 10 SecureCoins in the past 2 days. These are worth 0.00094 bitcoins (BTC) on Cryptsy at present. A doge is worth 0.0000007 BTC at present, so if I go from SRC -> BTC -> DOGE, I can turn 5 SRC to 6,642 DOGE on Cryptsy. There are also other exchanges, I won't go into how to exchange coins on this post. Remember, this is every day for about a week, for free! Also, you can CPU mine on your own personal computers as well, not just the servers. TL;DR Mine QuarkCoin / SecureCoin using Windows Azure free trial, use Cryptsy (or other exchange) to convert to DOGE. Much more efficient than CPU mining Doge.
Running staking Lore clients paves the way for some of the future use cases of BLK utilising the Bitcoin 0.12 (and newer) core tech, including colored coins. So I'm going to leave this one going indefinitely to kickstart the number of Lore clients staking. It's certainly not mandatory but it will be good in the longer term to have a nice distribution of Lore staking clients.
The cross-compile which lets you create binaries for multiple platforms didn't work for the QT version on the Pi, so there is more to do than just running the binary unfortunately, as below. There are folks working on some much cleaner solutions than this for the Pi, with a custom front end, and where you won't have to do any mucking about. That is coming soon. In the meantime, if you enjoy a fiddle with such things, here's how to get this QT client working on your Pi.
These instructions assume you are starting from scratch with a completely blank OS.
Note they have since (August 2017) released a version called 'Stretch' which does not work with this guide. I'll see if I can come up with something new for that at some point and link to it here when I have. In the meantime the guide should work with the Jessie image above.
Unzip the file and extract the .img file to burn it onto Fresh SD card to boot from (to be safe, use 16GB or larger), using a tool like win32diskimager or Etcher.
Assuming you have keyboard/mouse and monitor plugged into your pi, boot it up and the Jessie Desktop will show.
Before we do anything else, you should increase the default swap size on the pi, as compiling certain libraries can exhaust the RAM and get stuck otherwise. To do this, launch a Terminal window and type:
sudo nano /etc/dphys-swapfile
and Change the CONF_SWAPSIZE from 100 to:
Exit nano with control + x to write out the file.
Then, run the following to restart the swapfile manager:
(If you prefer to compile it yourself instead, it is possible by following the instructions in the original article by Mindphuk just taking into account this is the newer version of the Lore client than when that was written (https://github.com/janko33bd/bitcoin/releases) and the versions of Boost and the Berkeley DB need to be the same as below.)
Double click the zip and extract the Lore binary files. Yes, at the moment they are all called 'bitcoin', not 'blackcoin' or 'Lore' - this is because the code derives from a recent bitcoin core implementation so this has not yet been updated. You can place these wherever you like.
In the Terminal window, change directory to where you put the binaries, e.g.:
cd Downloads/lore-raspberrypi-armv7-jessie-pixel chmod +x *
That marks the binaries as executable.
Now, we need the Boost libraries installed for any of the Lore binaries to work. The project was done with Boost 1.62.0. Unfortunately the Jessie repository only goes up to 1.55, so we need to download and build 1.62 manually on the device.
wget https://sourceforge.net/projects/boost/files/boost/1.62.0/boost_1_62_0.tar.gz/download tar -xvzf download cd boost_1_62_0 sudo ./bootstrap.sh sudo ./b2 install
(This will take almost 2 hours. Have a nice cup of tea and a sit down.)
When I came to run the binaries, I found they couldn't find Boost. Running this command fixes that:
Now we are going to install the packages which aren't already included in the default OS installation which the binaries need in order to run:
Place the bootstrap.dat file into the ~/.lore directory.
Run ./bitcoin-qt again, it will say 'Importing Blocks' rather than 'Synchronising with Network'. My pi sync'ed fully in about 5-6 hours.
If you want peace of mind that Lore will always start on bootup into the Jessie w/Pixel desktop (i.e. after a power cycle), then you need to create a .desktop file in the following place.
sudo nano ~/.config/autostart/Lore.desktop
And in it, enter the following (tailoring the Exec line below to the whereabouts of your bitcoin-qt file):
[Desktop Entry] Name=Blackcoin Lore Comment=Mining without the waste Exec=/home/pi/Downloads/lore-raspberrypi-armv7-jessie-pixel/bitcoin-qt Type=Application Encoding=UTF-8 Terminal=false Categories=None;
Power usage and payback time
After a good while leaving it going by itself, the CPU load averages got down to almost zero, all of the time. Idling, the Pi uses a bit less than 3 watts. This means it would take two weeks to use one 1Kw/h of electricity.
If you pay e.g. 12.5 cents a unit, that's what you'd expect this to cost to run in a fortnight. That's around $0.25 a month or $3 a year. Green and cheap and helping to secure the BLK network. I paid for the year's worth of electricity in 2 days staking with 25k BLK. Makes mining look silly, huh? ;)
Securing your Pi
With staking, your wallet needs to be unlocked and as such, the keys to your wallet are on the device. In a clean and newly installed environment as described above, and if you don't allow others to use your device and there is no other software or nasties running on it, there is no real cause for concern. However, there are some basic security precautions you can take.
Firstly, if you have enabled SSH and are playing with your pi across your LAN (or worse, the Internet), you should immediately change the password for the default 'pi' user (which is preconfigured to be 'raspberry'). Simply log in as normal, then type:
You'll be prompted to enter the old and the new passwords.
Security by default
Your Pi is likely, by default, to not be exposed to incoming connections from the outside world because your router is likely generating a private address range for your LAN (192.168.x.x or 10.0.x.x or 172.x.x.x) which means all incoming connections are effectively blocked at the router anyway unless you set up a 'port forward' record to allow packets arriving on certain ports to be forwarded to a specific internal IP address.
As for accessing your Pi across the internet, if you have set up a port forward, this likely has security ramifications. Even basic old fashioned protocols have proven in recent times to have uncaught flaws, so it's always advisable to lock down your device as much as possible, and even if you only plan to access the Pi over your LAN, install a firewall to configure this. I used one called ufw, because it's literally an uncomplicated firewall.
sudo apt-get install ufw sudo ufw allow from 192.168.0.0/16 to any port 22 sudo ufw --force enable
This allows just port 22 (SSH) to be open on the Pi to any device on my LAN's subnet (192.168.0.x). You can change the above to a single IP address if paranoid, or add several lines, if you want to lock it down to your LAN and a specific external static IP address (e.g. a VPN service you use). To find out what subnet your router uses, just type:
and you'll see on the interface you are using (either hard wired or wifi) the 192.168 or 10. or 172. prefix. Change the above rule so it matches the first two octets correctly (e.g. 10.0.0.0/16 if you're on a 10.0. address).
You may already use VNC to access your Pi's desktop across your LAN, this uses port 5900. Add a line like above to lock it down to an internal address. It's not a good idea to expose this port to the wider world because those connections are not encrypted and potentially could be subjected to a MITM attack.
You can query the status of the firewall like this:
And of course, try connecting remotely once you change the rules to see what works. You should consult the official documentation for further options: https://help.ubuntu.com/community/UFW
Back up & Recovery
There are again many ways to tackle this so I'll just speak about my basic precautions in this regard. Don't take it as a be-all-and-end-all!
The wallet.dat file is the key file (literally) containing all the private/public keys and transactions. This can be found in:
You can navigate there using Jessie w/Pixel's own file manager or in a terminal window (cd ~/.lore). You can copy this file or, if you'd rather keep a plain text file of all your public and private keys, use the 'dumpwallet' command in the console. In Lore, go to Help > Debug Window > Console and type 'dumpwallet myfilename' where myfilename is the file you want it to spit out with all your keys in it. This file will end up in the same place you launch bitcoin-qt from.
The instructions earlier on, when running Lore for the first time intentionally left out encrypting your wallet.dat file because in order for the wallet to stake upon startup, it needs to have a decrypted key already. This isn't perfect, but after a power cycle, it would never stake unless you left it decrypted. So the best practice here is as soon as the wallet.dat file has left your device, i.e. you copy it to a USB stick for example, put it in an encrypted folder or drive (or both).
On the Mac, I use a software package called Concealer to encrypt files I store on the Mac itself: http://www.belightsoft.com/products/conceale There are almost certainly free packages with similar functionality, I have just used that one for years.
Note that these disk encryption methods may mean having to access the USB stick on a PC or Mac in order to retrieve the files in the event of a disaster. Be aware this may mean exposing them to more security issues if your computer is in any way compromised or someone nefarious has access to your computer. There are more 'manual' ways of backing up and recovering, such as literally writing down private/public key pairs which this guide doesn't go into, but may suit you better if paranoid about your setup.
The wallet.dat file has everything in it you need to recover your wallet, or if you used 'dumpwallet', the file you saved out has all the keys.
Wallet.dat method: Install Lore as normal then replace any auto-generated wallet.dat in ~/.lore directory with your backup. If a lot of time has elapsed and many transactions have occurred since your backup, launch lore with:
And if that doesn't do the job, do a full reindex of the blockchain:
If you used the dumpwallet command, install Lore then place the file containing all the keys that you saved out in the same directory as bitcoin-qt. In Lore, go to Help > Debug Window > Console and type 'importwallet myfilename' where myfilename is that file containing all the keys. The wallet should automatically rescan for transactions at that point and you should be good to go.
There are a million ways to do effective security and disaster recovery, but I hope this shows you a couple of basic precautionary ways. There are discussions about better ways to stake without compromising too much security which are happening all the time and developments in this regard will happen in time.
In the meantime, feel free to comment with your best practices.
WHAT IS A DOGE VANITY ADDRESS Vanity addresses are ones where you can choose what characters appear somewhere in the address. For example, DPie5ucpypDTUsgquc3ea2Meg6TwpW6mW1. All Doge addresses must start with D (capital) and the second character must be a capital if it is a letter (not all letters accepted, for example I O Y W are not allowed as the second character). You can also create letters or words at the end or even beginning of the address such as:
Letters that I have found valid as second characters are: 5 6 7 8 9 A B C D E F G H J K L M N P Q R S T U HOW TO CREATE YOUR VERY OWN DOGE VANITY ADDRESS
Unzip it to a folder you can easily access via command line (c:\vanity is a good example)
Launch “Command Prompt” and go to that folder (“cd c:\vanity” if you chose that folder)
Choose the generator you will use. Use “vanitygen.exe” or “vanitygen64.exe” for CPU gen or “oclvanitygen.exe” for OpenCL devices Command will be one of the following (replace Doge with what you want to generate)
oclvanitygen.exe -X 30 -p 0 DDoge (you may need to change “-p 0″ to “-p 1″
vanitygen64.exe -X 30 DDoge (Use this if the above command does not find a valid GPU)
This will continue searching through the chain until it finds a privatekey that signs an address beginning with DWord
Once one is found, it will show you the Address and the Private Key (read below on how to import)
You can use “-k” to “keep searching after a match and “-r” to accept regex (useful for finding a suffix instead of a prefix)
You can direct the output to a text file with “-o filename.txt”
You can have it read a list of different terms from a file using “-f list.txt”
If you get an error that states Bitcoin addresses can only start with a “1″, then that means your second character is invalid. Make sure it is an UPPERCASE character and if that does not work, try a different character. Again, O I Y W are not allowed for second characters. If the error states that a specific letters such as “O”, “I” or “L” is not allowed you can try using a lowercase version of it.
HOW TO IMPORT YOUR NEW DOGE VANITY ADDRESS INTO YOUR DOGECOIN-QT WALLET
You need to save the Privatekey from above to use the address.
Open your Dogecoin wallet client if its not open already.
Go to Help > Debug Window > Console
If your wallet is encrypted and locked, type in: walletpassphrase “YOURPASSWORD” [seconds to stay unlocked]
Now type in: importprivkey “TheVeryLongPrivateKeyThatYouReceivedFromTheLastStep” “A nickname for this wallet”
You should see the command be accepted, and it will stay processing the key for 5-60s
You will see another line with no text show when complete. The icon will have red text on it vs the green text that your commands icon had. Once you are done importing all of your privatekeys into the client, you will need to restart it to see them in your list.
Guide: How to redeem and sell bitcoin diamond (bcd) from ledger nano s (Segwit)
I spent two days to figure this out but I think I know how to solve this, just currently stuck and need your help! I had btc stored on a nano s segwit wallet before the fork. Bitcoin diamond was forked from bitcoin on block #495866 (nov 24 2017) and launched the mainnet Jan 5 2018 (I think). There is currently very little information about this project and very little support on exchanges, wallets and mining. http://btcd.io The only light wallet currently have a splitting tool is Bither for Android but they do not support Segwit. If you had your btc in a segwit wallet before the fork you can't use this method. Otherwise follow this: https://steemit.com/bitcoin/@tiberiu/how-i-claimed-sbtc-super-bitcoin-from-my-paper-wallet Or this: https://www.reddit.com/BitcoinMarkets/comments/7oekie/guide_how_to_redeem_and_sell_all_bitcoin_fork/ You get 10 bcd for every btc and current price is 0.001 btc. That means you get $160/ forked btc which is 1% free money. Is it worth it? For me it is. You can use same method for both SBTC and BCD. Other methods can be used for BTX, BCX and BFX but have to wait for me. Need segwit support in Coinomi and/or Bither. In my BCD case it was a bit more complicated but hopefully possible.
Enter your ledger 24 word mnemonic. Select BIP49 derivation path. Find your btc address that contained btc right before block 495866, copy private key. Use a block explorer: https://blockchain.info
Find the tx ID that sent those btc and verify in bcd explorer if you have any bcd before you continue (click on the actual address will not work for some reason, shows empty). My tx had 3000 confirmations. http://explorer.btcd.io
Actually quite cool you can run Ubuntu on Windows 10! You can build for 32 bit as well but not when you have installed dependencies for x64. The last step will copy the binaries to your windows folder: "make install DESTDIR=/mnt/c/workspace/bitcoindiamond"
Run bitcoindiamond-qt in windows and let it sync with network. Took me 12h with fiber connection.
Go to help and open console. If your wallet is encrypted, decrypt for 10min using: "walletpassphrase your-wallet-passphrase 600".
Import old btc address as watch-only to check bcd balance. True means it will rescan the blockchain. Rescan took 1h with a decent PC (no SSD):
If you see your BCD balance, now Import your btc private key into the watch-only address. No need to rescan again, thus "false".:
Ok here is where I'm stuck. I can see my balance but it's not spendable. I also tried to import private key directly (with sync) with empty core wallet but balance is still zero. It does not pick up the transaction! Anyone know how to solve this? Rest of the guide when this is solved:
You should now be able to access your bcd!
Go to gate.io (register). Deposit bcd to exchange from bitcoindiamond-qt. Try small amount first, use a proper fee.
"1) I can backup my wallet by exporting a wallet.dat file. Do I have to do this everytime I receive more BBP? Or just whenever I add a new key? 2) How do I add new keys? 3) Can I generate and see the private key so that I can write it down/print it and store it somewhere safe?" -znffal 1) think of your wallet.dat file as your passbook in a passbook savings account. You have to have that .dat file to be able to access (and prove you SHOULD have access) to the BBP stored in your account addresses. Exporting it once is all you need. 2) Adding new keys? The passphrase (password) you use is the only "key" you would have in an encrypted wallet (besides the .dat file). If you mean new addresses, you can get those by going under File and Sending (or Receving) Addresses and hit "new". 3) Clicking Encrypt Wallet will be where you choose a passphase, I don't know you can see it other than when you enter it. To put a real world example or two. Example One: You don't ever encrypt or backup your wallet. If I borrowed/stole/hacked your computer, I could send all your coins to my wallet (no passphrase). Example Two: You encrypt your wallet with the passphrase "secret" but don't backup the wallet.dat file, then your computer crashes and you lose all your data. Since you didn't have a copy of the wallet.dat file, your coins would be lost. Example Three: You backup your wallet.dat but don't encrypt it. Your computer crashes and all your data is lost, but you re-download the QT program, restore your wallet.dat, all your coins are still in you wallet. But if you lose your USB drive that has the wallet.dat on it, and I find it, I can put your wallet.dat on another computer and send all your coins to my wallet. Example Four: You encrypt your wallet and back up the wallet.dat file. If I hack/borrow your computer, unless I guess your passphrase your coins are safe. If you computer crashes, your can restore your wallet.dat file to another computer and your coins are safe. In short, Encrypt your wallet (passpharse) and then backup (copy) the wallet.dat file to at least two locations." -616westwarmoth "Find your wallet.dat file, copy it to a flash drive or any other secure place. If your computer crashes, you'll always have the wallet.dat and can put it on a new machine. It will have to resync a bit when you do, but you'll never lose your "key" to the wallet. Speaking of keys, you should password protect your wallet and make sure to remember it!" "Yes you must have a copy of the wallet.dat somewhere. So multiple back up copies are a good idea. If you lose the wallet.dat file the coins will be in limbo but there will be no way to recreate the file. One thing to remember is it doesn't matter if the wallet.dat file is "current", it can be 10 years old on a flash drive and you can download a new client, put the wallet.dat file into the machine and you'll be good." -616westwarmoth "In addition to this, whenever you reboot the node after more than 24 hours of being synced, we back your wallet.dat up into the "backups" folder. This is useful if you ever accidentally delete your wallet.dat. Also, if you want a paper backup, you can do a 'dumpprivkey accountaddress' command from the RPC." -Rob "wallet is a collection of private keys" "there are other ways to achieve high security. You can make a new wallet, encrypt it with a long password, send coins to it, put it on a flash drive and put it in cold storage, then download the hard drive cleaning program and erase the wallet.dat sectors from your PC. And of course, keep a printed copy of the private key on paper and put it in a safe. Put the usb in the safe also. Burn a cd rom with the wallet.dat file and put it in the safe." -Rob How to safely back up your wallet https://dashpay.atlassian.net/wiki/spaces/DOC/pages/1867878/How+to+safely+back+up+your+wallet Keep Your Crypto #SAFU (CZ's Tips) https://www.binance.com/en/blog/421499824684900429/Keep-Your-Crypto-SAFU-CZs-Tips References: https://bitcointalk.org/index.php?topic=2042657.msg23955128#msg23955128http://forum.biblepay.org/index.php?topic=27.0https://bitcointalk.org/index.php?topic=2388064.msg27797529#msg27797529 To Read: https://en.bitcoin.it/wiki/Wallethttps://en.bitcoin.it/wiki/Storing_bitcoinshttps://bitcoin.org/en/secure-your-wallet NOTE: As of version 126.96.36.199 we have updated to HD wallets, so you should not need to worry about keypools anymore if you have upgraded "Regarding the Sanctuary, you receive payments always to the same address (key), so the keypool is not consumed for those payments. But when you click to generate a new address on the "Receive" tab, one key will be deducted from the keypool. Also, sometimes new addresses are automatically generated and the keypool is consumed, for example when solo mining and finding a block, a new address could be used for the block reward. You can always check your current keypool size by typing "getwalletinfo" in the RPC console and see "keypoolsize" and "keys_left". It's only concerning if they are a low number and you plan to generate new addresses in your wallet. They start from 1000. If the number gets too low, you can just type "keypoolrefill" to refill them back to 1000 and then you should backup the wallet. But from my experience the wallet automatically refills the keypool from time to time (or after certain actions like transactions), because I see that my wallet file keeps getting larger and the "keys_left" returns to 1000. The only issue is if you actively use your wallet on multiple computers (for example cloud mining or simply sometimes using the wallet on your laptop), then one wallet could refill the keypool with new addresses and the other one will not, or they will generate different new addresses. If I understand this correctly, for example, you could receive a payment on a new address generated in one wallet; your old balance will be there on both wallets, but only the one wallet where you generated the new address would show the new payment. Then you should copy the wallet.dat file to other computers, to update them. If you use the wallet on just one computer, you should just backup the wallet from time to time (or when you see it has increased in size). Qt also backups wallet.dat automatically, those can be found in the folder %AppData%\BiblepayCore\backups, you will see that they also have timestamps in their names and possibly different sizes." -inblue https://bitcointalk.org/index.php?topic=2388064.msg27391534#msg27391534
[Beginner] Questions so stupid I should have made a throwaway
Let's get the most embarrassing question out of the way first. Yesterday I downloaded my first ever crypto wallet Dogecoin qt-1.6. It was 14 weeks behind so I ran it several hours until it was synchronized. Closed the window once syncing was complete, and now I don't know how/where to access it after searching my computer for the file/program. I understand that this question is so dumb that there's no search results on /dogecoin or google, but: Where on my computer is that empty wallet that I synced for hours yesterday? It's obvious I'm not understanding what a Wallet is since I don't know where to find it after running the exe. I want to buy my first dogecoins. I have no other cryptocurrency, this would be my first, and I'm getting the sense that dogecoin is not for new users who can't mine, but for people who are already in the crypto market with bitcoin/litecoin and can convert these into dogecoin. Is this a reasonable assumption, being that I can't just buy dogecoin with credit card/bank account? I made an account on Coinmkt.com and they will only allow purchase through ego pay, ok pay or money order. Searching reddit for how to buy, I found a recommendation of cash -> coinbase -> BTC-e -> Litecoin -> wallet, so is it the same for dogecoin? I have made a Coinbase account, but I'm starting to feel that this "club" is turning out to be a bit more exclusive than I had anticipated and while I don't mind doing some work before I can participate, the barriers for entry are making me second guess whether a total crypto newb is really welcome to jump in without first being serious about Bitcoin to get access. Am I off-base? (I'm a little discouraged but not ready to give up). Edit: You guys are amazing, and I was able to find my dogecoin files (the appdata\roaming folder was hidden), set the dogecoin.exe as a shortcut on my desktop, and am going to give Coinbase a try for buying some bitcoin that I can convert to dogecoin. (I assume there's a tutorial on how to go from Coinbase btc to Doge somewhere?). An hour ago I felt like an outsider, and now I'm looking forward to being part of this community rather than just a confused lurker. Final question for today if anyone sees it: Would Dropbox be an ok place to keep a backup of my wallet once I get some funds in it?
There's multiple ways you could go about doing this. Here are two methods that I know. You could have a usb, external hdd, etc. with your wallet on it (Basically making a mobile wallet).
Here's how you would do this on Windows.
Download the windows .zip from dogecoin.com
Extract the folder from the .zip file.
Make a text file within the extracted folder called launch.txt
Put this in it: start bitcoin-qt.exe -datadir=data
Rename the text file to launch.bat
Make a folder called data
Double-click launch.bat to start it. If files show up in the data folder you made, it's done.
I see this being moderately safe as you always have your wallet with you. I do believe that the only way someone can gain access to your wallet is if they get the files from the USB or the USB itself. Although I am unsure of the threat of using your wallet on multiple machines as far as hacking goes. OR You could have a designated laptop/machine for your wallet.
Start out with a clean install of windows onto the machine.
Get the .zip from dogecoin.com (Download, usb, etc.) onto the designated machine.
Only connect the machine to the internet for wallet/doge use.
And only use the machine for transfers from/to yourself.
Think of this method as a bank. Your main machine, machine A, is used for everyday use (So mainly Reddit). Machine B is your "vault/bank" or "offline" machine. All obtained doge (from mining, tips, services, etc.) are sent to Machine A. From there, you would send said doge to Machine B. You would then turn on Machine B, connect it to the internet and confirm that the doge was received. Machine B would then be disconnected from the internet. Now you have an offline machine (vault/bank) holding your doge. Now lets say that you want to spend some of your doge. Turn on/Connect Machine B to the internet. Now send the desired amount of doge from Machine B to Machine A. Then disconnect Machine B from the internet. The amount of doge that you wish to spend is now on Machine A rather than Machine B.
Machine A is your "wallet" which carries around your doge that you wish to use.
Machine B is your "bank" which holds your doge that you wish to store.
This is probably the safest method that you could use between the two or just in general. I guess if you wanted to be even safer, you could always use different addresses between transactions between your machines. Also, you could have multiple offline machines/wallets to spread your doge between to be even safer. Or even mix these two methods so you would have both a mobile wallet, offline wallet (bank), and your online wallet (main machine). Edit: formatting

I got tired of waiting and waiting for the whole blockchain to sync so I decided to move my dogecoins to my phone since the app does not need to download the whole chain. (Luckily there is a bounty for a electrum equivalent that will hopefully arrive soon.) It is much much easier if you just transfer some funds to a new address on your android phone, but this tutorial is for those people like me who can't even get the dogecoin app to sync. Surprisingly the whole process was very simple. Don't be put off by all the text or all the talk about security. I just want things to be accessible to beginners and to practice good habits. Root is not required. Note: I am assuming you are using the official dogecoin-qt app and the Dogecoin Wallet app by langerhans. Disclaimer: This will involve having your private key stored in plaintext. Proceed with caution and treat that file like you would a password. Do not share your private key with anyone.
Getting your private keys
A wallet comprises of public keys and private keys. Public keys are the addresses that you share, you can only use them for viewing. Private keys let you actually make transfers and are what makes you the owner of the wallet. Today we will be transferring those private keys to your phone. They will still be present on your computer unless you delete them, so keep that in mind security-wise. You will have to replace everything in '<>' with your own values.
Open the desktop app
Open the wallet console by going to: Help -> Debug Window -> Console
If your wallet is locked with a password, you'll need to unlock it by typing: "walletpassphrase 120".
Get the private key for an address by typing: "dumpprivkey "
Save the private key to a file.
Repeat this for each address that you want to transfer over.
Please think about how much dogecoins you want to transfer over. Brarsh:
Do you need that much? What if you lose your device? Just like only keeping a small amount of cash in your wallet and most safe in the bank, only carry what you could conceivably use for that time without access to your main wallet.
Creating a backup file
Next we need to create a backup file so that we can import our addresses into the android app. The android app uses the same format for its backup files as MultiBit (A popular bitcoin app). A typical file looks like the following:
# KEEP YOUR PRIVATE KEYS SAFE! Anyone who can read this can spend your Bitcoins. Kwmxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx 2013-06-22T18:36:35Z L1Sxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx 2013-05-04T22:47:32Z Kxwxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx 2013-05-08T00:58:28Z
What we want to do is put our private keys in the following format: key date-of-address-creation, where the date is in the format YYYY-MM-DDTHH:MM:SSZ. Note the T and the Z. The android app needs the date so it knows how far back into the blockchain it needs to sync. If you can't remember when you created the address, visit http://dogechain.info/address/YOURADDRESS and get the date of the earliest transaction. It says that the dates are approximate, so I'd just put 00:00:00 for the time. You should now have a valid unencrypted backup of your wallet.
Importing the backup
Transfer the backup to your android phone, placing it in your Download folder. It has to be put in the Download folder or else the dogecoin app won't find the backup. Make sure it has a name you'll remember later.
Open the dogecoin app and click on: Back Up Keys -> Restore private keys. Click on the name of the backup and from the list that shows up, look for your backup, which should be unencrypted. Click Restore.
Delete the backup in your Downloads folder. Remember, your private key is stored in plaintext in there, so it is important that you delete it. Delete the backup on your computer if it is there also.
Wait for the app to sync completely. Your addresses will be added to the addresses that were already in the app, and your transactions should show up. If they do not, make sure that the date you put was correct and early enough.
Go to Back up Keys > Back up private keys and create a backup. This time it will be encrypted with a password :). If you do not have a backup, you could lose all your coins if you lose your phone or the data on it.
To the moon!
I just got into dogecoin two days ago so correct me if any of this is wrong. Same thing with anything in the post :). Blockchain/Dogechain: The blockchain is a ledger (record) of all the dogecoin transactions that have ever taken place. As of writing it is larger than 1GB in size. The blockchain is needed to find out how many funds you have in your wallet. Wallet: A wallet is the digital equivalent of a real life wallet. It is where your money is tied to (It doesn't contain actual dogecoins, but someone else could explain that better than me). The wallet contains your addresses and your private keys, both which are needed to receive and send dogecoins respectively.
I thought would put together another tutorial for anyone looking to get started with mining CannaCoin's. it is a bit of a plug for my own mining pool ccn.surmine.com, but you're free to mine of another pool, the process is pretty much the same. Once broken down into individual parts the whole process is quite simple and should only take less than half an hour to start mining. The process can be broken down into the following stages:
Setup CannaCoin Wallet: This is where you keep coins.
Create Mining Pool account: This is where you work with others to mine coins.
Install GPU Miner: This is the software you need to mine.
Mine: Start the application and watch the magic.
Stage 1: Setup CannaCoin Wallet
Go to [cannacoin.cc](cannacoin.cc) , click on download wallet then Download and select the windows client and save to your PC. Setup Image 1
Open the CannaCoin wallet you downloaded and browse to the Cannacoin-QT folder. Setup Image 2
Drag the contents into the Cannacoin folder you created on your C drive. Setup Image 3
Double Click cannacoin-qt, you will asked to allow access to through your firewall, click "Allow access". Setup Image 4
Your CannaCoin wallet is now running. It may show "No block source available" in the bottom left corner, give it 15 mins and it should connect to the network, if not check your firewall settings. Once you see "Synchronizing with network" in the bottom left you know you are good. Setup Image 5
Click the Receive tab and write down your CannaCoin address, this is your address to receive coins. Setup Image 6
Stage 2: Create Mining Pool account.
There are multiple pools you can choose from but as I run a mining pool I might as well plug my own ccn.suremine.com , If you would like to use another the following steps will work with another pool.
Complete the registration form, make sure you choose a good password that is unique to this poll, write down the PIN, as if you lose it you lose your coins! Account Image 2
Check your email and Click the email verification link, if you can't see the email check your spam folder.
Login to your account and Click "My Account" then click "Edit Account" On the Left Hand Nav. Enter your PIN and click unlock. This will create a confirmation email you will need to click. Account Image 3
Check your email and Click the email verification link, if you can't see the email check your spam folder.
Set your payment address ( the one you copied down when you created your wallet).
Set your Donation Percentage ( this helps keep the pool running).
Set your automatic payout threshold ( low to start with to see the funds come through).
Once Downloaded, unzip the file, go into to cduaminer-2014-02-28 then into x86 and drag the contents of the zip file into the GPUminer folder. By the time you're doing this the date of 2014-02-28 may have changed to a newer version, that's good news!) Install Image 2
Open up notepad and insert the following text, you want to replace the worker login and the worker password with the values you noted down earlier. cudaminer.exe -o stratum+tcp://uk.suremine.com:6666 -u USERACCOUNT.WORKERUSER -p WORKERPASS pause Install Image 3
Select File > Save as then save the file to c:/GPUmine as gpuminer.bat. Install Image 4
Stage 4: Mine
From the C:/GPUminer double click gpuminer.bat this will open a window. after a few minutes you should start seeing accepted transactions. All accepted transactions are good. Mine Image 1
When you launch gpuminer.bat if you see the following error it means you need to update your Nvidia drivers: Error Image 1
Users have also reported needing to install CUDA Toolkit and Visual Studio, if you hit issues please try installing these applications.
If you are looking to get the most out of your Nvidia card you can update gpuminer.bat with config from the Nvidia Comparison Table
