Issue upgrading my bitcoin node
Hello, I'm trying to update my current node (v0.18.1.0). I'm running my node on Mac using an external HD. Everything is on my HD except for the bitcoin.conf file and the Bitcoin Core icon in my Applications folder. I was able to launch my node using the icon on my Application folder (bitcoin-qt) or using the command line (bitcoind) Since I downloaded the new version (v0.19.0.1), I have the following issue: When I launch my node using the icon on my Application folder (bitcoin-qt) everything is fine and the new version is running (using the data in my external HD), but when launch the node using the command line (bitcoind), it still launch the old version. Is there a separate update from bitcoind? I've done some research online but I didn't find anything helpful. Thank You!!! ***EDIT*** I have downloaded "bitcoin-0.19.0.1-osx64.tar.gz" which include the executable for bitcoind, bitcoin-cli, etc and replace the old ones by the new ones and everything looks fine!
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: v184.108.40.206-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
[PSA] Dogecoin Wallet version 1.4 released. You must update.
WARNING: DO NOT send your wallet.dat file or dogecoin folder to anyone. There have been reports of people offering to help others by asking them to send their files to them so they can help. DO NOT do this. Scam attempt picture Always encrypt your wallet! I can't express this enough. You should use a strong password longer than 15 characters. This password should contain numbers, symbols, and some capitalization! There is no need to have your wallet open 24 hours a day. Open it only when you need it. See - 'Getting Started' on the side bar. This entire post has been written to be as close to ELI5 (Explain it like I'm 5) as possible - By request!

Open the downloaded file and extract the contents of the downloaded file into any new folder or location on your computer. If you put the files into a folder you can name the folder anything you want but make sure you remember that this is the latest version of the software. You don't have to remove your folder containing the old version of the wallet. You can place it in a folder called 'Old versions of dogecoin wallet' if you like. Now you can click on the Dogecoin icon contained in the new folder to open your version 1.4 wallet. What happens if I get an error when I open the new wallet? An error was reported called "11DbException" If this happens Download this file and place it in the same folder as your updated wallet. Open the file you just downloaded called "Dogecoin OPEN' and wait. This might take 2 or 3 minutes. Also jtlarousse has found a solution that worked on Windows. Please follow carefully and make backups before starting. Reebzy might have found a solution for Apple Mac Blockchain fork 101: The block chain is a ledger or document created containing every transaction that has ever happened. This file can be quite large. Bitcoins ledger is over 15GB. At some point this document/ledger split into two separate documents known as a fork. How do I know if I am on the right block chain? Go to your newly updated dogecoin wallet and open it. Click on Help>>Debug next Observe the current block number *Notetheexamplenumbersinthepicturesmightbeoutofdatebythetimeyoureadthem Now go over to http://dogechain.info/chain/Dogecoin . This website is the official Dogecoin blockchain website. Check the block number they're reporting The number you found in your wallet and the number reported on the website should close. There might be a difference of 100 blocks depending on when you last refreshed your wallet or how long it took for you to get from one step to the next step in this guide and if the dogechain website is lagging. I'M NOT ON THE CORRECT BLOCK CHAIN My numbers are very different. How do I get back onto the right block chain? IMPORTANT For windows: 1)Close down the Dogecoin wallet client. 2)Go to your data folder: C:\Users[your windows log-in name]\AppData\Roaming\DogeCoin 3)Delete the Dogecoin.conf file. Do not delete the wallet.dat file! 4)Download this update file and place it into the Dogecoin folder where the other file was deleted. For Apple Mac: 1)Close down the Dogecoin wallet client. 2)Go to your data folder: ~/Libarary/Application Support/Dogecoin 3)Delete the Dogecoin.conf file. Do not delete the wallet.dat file! 4)Download this update file and place it into the Dogecoin folder where the other file was deleted. Next visit this post by Netcodepool for instructions on how to manually download the correct block chain and install it.
Edit: Some posts were removed from this thread. To limit confusion. Check this post for details about mining pools that were/are using the wrong fork. Did you send coins only to find out you're on the wrong chain? See this post to get them back An Apple Mac support thread has been made by voidref (The mac developer). If you're having troubles please see this thread Some shibes have reported their wallets wont sync. Please check to make sure your firewall, antivirus, malware scanner or similar programs are not blocking it the wallet. You can add rules to these programs to allow the wallet to make contact with the internet. It's not advised but possible to also disable the software for a short amount of time. Don't forget to enable the software again afterwards. Is your wallet crashing? Try this helpful tip from gandhikahn or if you're using windows try the 1.4.1 update above.
Upgraded the staking system and improved staking efficiency.
Updated QT to 5.9.7. This can fix the Mac version start-up problem for Mojave and High Sierra users. It also means that Bitcoin 2 Core software starting with v2.2.0 will no longer run on MacOS versions older than Yosemite 10.10.
Fixed a rare wallet crash scenario that could have happened while staking if one was beaten to the block and validating their created block.
Removed Qt4 build support and code fallbacks.
Fixed missing block explorer icon.
More than 99 confirmations will be required before coins can be staked.
If all other conditions are met, staking now begins after the wallet receives its first coins that can be staked without having to restart the wallet.
Changed the minimum transaction fee to 0.00003200 BTC2 per KB.
Removed explicitly unused transaction comparators that sometimes could have caused transaction timestamp display issues.
Completed the changes to claiming from the fork.
Started using the clock5.png icon when a transaction is almost confirmed.
Removed the stretched Windows installer icon.
Updating your Bitcoin 2 Core wallet to this version is mandatory. That includes upgrading all your Masternodes. After enough nodes have upgraded to this version, a new staking protocol will be activated and the old nodes that fail to upgrade their wallet before that will end up forking to the wrong chain. Estimated time of this protocol upgrade is between August 21 - August 24 2019. As soon as possible. To update, you just need to download the archive, stop your wallet and let it fully shutdown, and then copy the executable files in the bitcoin2-bin folder to replace the ones you had installed already. After upgrading your Masternode and your desktop wallet, you should go in the Masternodes tab on your controller wallet and click to Start the upgraded Masternodes. Binaries for a couple of platforms that are less used are still to be compiled.
how to shibecoin v rich in minutes much instruct so simple any doge can do
UPDATE 1/21/14: I'm not updating this guide anymore. Most of the steps should still work though. See the wiki or check the sidebar for updated instructions. Before you do anything else, you need to get a wallet. Until there's a secure online wallet, this means you need to download the dogecoin client. Now open the client you just downloaded. You'll be given a default address automatically, and it should connect to peers and start downloading the dogechain (aka blockchain in formal speak). You'll know because there will be a progress bar at the bottom and at the lower right there should be a signal strength icon (TODO: add screenshots). If you've waited 2 or 3 minutes and nothing is happening, copy this:
And paste it into a new text file called dogecoin.conf, which you then place into the dogecoin app directory.
On Windows this is C:\Users\[YOUR_USER]\AppData\Roaming\DogeCoin
On Macs it's ~/Library/Application Support/DogeCoin
Now restart your qt client and the blockchain should start downloading in about 1-2 minutes. Once it finished downloading, you're ready to send and receive Dogecoins!
Decide how you want to get Dogecoin. Your options are:
I'll go into detail about each of these. I'm currently writing this out. I'll make edits as I add sections. Suggestions are welcome.
Mining is how new dogecoins are created. If you're new to crypto currencies, read this. To mine (also called "digging"), a computer with a decent GPU (graphics card) is recommended. You can also mine with your CPU, but it's not as efficient.
These instructions cover only Windows for now. To mine, you'll need to figure out what GPU you have. It'll be either AMD/ATI or Nvidia. The setup for both is approximately the same.
Step One: Choose a pool
There's a list of pools on the wiki. For now it doesn't really matter which one you choose. You can easily switch later. NOTE: Youcanmineintwoways.Solominingiswhereyouminebyyourself.Whenyoufindablockyougetallthereward.Poolminingiswhenyouteamupwithotherminerstoworkonthesameblocktogether.Thismakesitmorelikelythatyou'llfindablock,butyouwon'tgetallofit,you'llhavetosplititupwithothersaccordingtoyourshareofthework.Poolminingisrecommendedbecauseitgivesyoufrequentpayouts,becauseyoufindmoreblocks.Thelargerthepoolyoujoin,themorefrequentthepayouts,butthesmallertherewardyouget. Overalongperiodoftimethedifferencebetweenpoolandsolomininggoesaway,butifyousolomineitmightbemonthsbeforeyougetanycoins.
Step two: Set up pool account
The pool you chose should have a getting started page. Read it and follow the instructions. Instructions vary but the general idea is:
Create an account
Create a worker under the account
Grab the mining URL (usually on the getting started page)
Setup your cash out options in your account settings by entering one of your wallet's receiving addresses
When you're done with this, you'll need to know:
Your account, worker name, and worker password
The mining (stratum) URL (usually the pool's URL followed by a port)
Step three: Download mining software
For best performance you'll need the right mining software.
Create a text file in the same folder as your miner application. Inside, put the command you'll be running (remove brackets). For AMD it's cgminer.exe --scrypt -o stratum+tcp://: -u -p For Nvidia it's cudaminer.exe -o stratum+tcp://: -O : Substitute the right stuff in for the placeholders. Then on the next line of the text file type pause. This will let you see any errors that you get. Then save the file with any name you want, as long as the file extension is .bat. For example mine_serverName.bat.
Step five: Launch your miner
Just open the .bat file and a command line window should pop up, letting you know that the miner is starting. Once it starts, it should print out your hash rate. If you now go to the pool website, the dashboard should start showing your hashrate. At first it'll be lower than what it says in the miner, but that's because the dashboard is taking a 5 minute average. It'll catch up soon enough. NOTE: Anormalhashrateisbetween50Kh/suptoeven1Mh/sdependingonyourGPU.
You're now mining Dogecoins
That's it, nothing more to it.
CPU mining isn't really recommended, because you'll be spending a lot on more on power than you'd make from mining Dogecoin. You could better spend that money on buying Dogecoin by trading. But if you have free electricity and want to try it out, check out this informative forum post.
Trading has been difficult so far, but Dogecoin just got added to a few new exchanges. If you don't have a giant mining rig, this is probably the best way to get 100k or more dogecoins at the moment. I'll write up a more complete guide, but for now check out these sites:
Faucets are sites that give out free coins. Usually a site will give out somewhere between 1 and 100 Dogecoin. Every site has its own time limits, but usually you can only receive coins once every few hours, or in some cases, days. It's a great way to get started. All you do is copy your address from the receive section of your wallet and enter it on some faucet sites. Check out /dogecoinfaucets for more. If you go to each site on there you might end up with a couple hundred Dogecoin!
This method is pretty straightforward. Post your receiving address, and ask for some coins. Such poor shibe. The only catch is, don't do it here! Please go to /dogecoinbeg.
Other redditors can give you Dogecoin by summoning the tip bot, something like this: +dogetipbot 5 doge This might happen if you make a good post, or someone just wants to give out some coins. Once you receive a tip you have to accept it in a few days or else it'll get returned. Do this by following the instructions on the message you receive in your inbox. You reply to the bot with "+accept". Commands go in the message body. Once you do that, the bot will create a tipping address for you, and you can use the links in the message you receive to see your info, withdraw coins to your dogecoin-qt wallet, see your history, and a bunch of other stuff. As a bonus, so_doge_tip has a feature where you can get some Dogecoins to start with in exchange for how much karma you have. To do this, send the message "+redeem DOGE" to so_doge_tip. You'll need to create a tipping account if you don't have one. If you want to create a tipping account without ever being tipped first, message either of the bots with "+register" and an address will be created for you.

The Gridcoin Developers are pleased to unveil 3.7.12 to you today, which is a massive release featuring over 450 commits over the last couple months. While being a large update it is still leisure, and users do not have to update. Download the update from GitHub here. The Windows MSI can be downloaded here.
Rather than posting the full release notes (because that would be ridiculous given the number of changes), I will instead showcase some of the more prominent and exciting features in this release. If you would like the full unedited changelog please see the Github commit list here.
New changes in this release include:
Gridcoin Research is now a 64 bit installation
This is largely due to the fact that our GUI management software has been updated to QT 5.9 and QT has dropped support for 32 bit operating systems. Note that this change was made by QT in June of last year, so this has been a long time coming. If you still require a 32 bit release, please do not use this leisure update and remain on 220.127.116.11 for the time being.
Please note however that we will be removing support for 32 bit entirely with the next mandatory release (Date TBD). This serves as a warning for those still on 32 bit systems: you have a few months before you will need to find a 64 bit OS to run the wallet.
We are pleased to share the new graphical user interface that has been in the development branch for over six months now. It's time for the new icons and artwork to be released to everyone. See below for a sample of the new GUI in default "light" mode:
To break down the new icons on the right, we have at the top the purple beaker for a POR (solo) Researcher reward. Below that we can see two red icons denoting outgoing transactions (sent to another wallet). Beneath that we see an incoming transaction (in this case from grcpool). Finally at the bottom we see the icon for sending transactions to yourself.
Also take note of the great new art for the icons on the lefthand side, with the new purple coloring throughout the wallet's UI.
The Gridcoin RPC commands have received a large overhaul to make them more consistent with commands used by other "Bitcoin-like" wallets. The most notably changes come in the form of removing the keywords execute and list from commands. Any command that used these prefixes previously, such as list rsa for example, will now be changed to run without the prefix. So the old command list rsa is now simply rsa in the new wallet.
In addition many new RPC commands have been added, although many of these are used for internal debugging and logging purposes by testers and developers. For full RPC documentation please see the GitHub commits linked above.
New AutoTools Build System
This item is mainly of interest to those who self-compile or manage packages themselves. Gridcoin has switched to the AutoTools build system which greatly simplifies the process of self-compiling the wallet across all platforms. If you self-compile or need information about AutoTools, please refer to the documentation in the /doc/ folder on GitHub.
Neural Network Enhancements
With this update we introduce many improvements to the Neural Network used by Windows nodes that should improve consensus, decrease sync time, and generally make the entire process of creating superblocks smoother. As stated above the full changelog for the NN can be found in the GitHub commits.
These are far from all the changes, but these five are the ones we would like to specifically showcase for the average wallet user. We hope you will be happy with the new release and look forward to your feedback.
As always, thank you to all the developers who contributed to this release, including but not limited to: @ravonn, @ifoggz, @tomasbrod, @thecharlatan, and @jamescowens.
I would also like to thank all our dedicated testnet users who helped to find bugs and issues to ensure a smooth release. Special thanks to @noah-blaker, @jamescowens (again!), and @GlenArm for going the extra mile to assist debugging tricky last minute issues.
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/v18.104.22.168/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!

[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.
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.
Hmmm? How do I get the correct balance out of the fullnode wallet?
As the full node wallet became available I downloaded and installed. Well basically it's still the bitcoin core bitcoin-qt desktop application. Now I imported my private key in which there was bitcoin at the time of the split. I expected the amount of BTG to show up in the wallet and then go from here.... But it seems this full node wallet also shows when I spent my bitcoin after the split... I am confused: Isn't that the whole idea of the split that after importing the private key into the new wallet I only see the transactions I do or have done on the new chain and not the others as well... Well, what a mess, how do I have to proceed to ensure the new wallet recognizes that amounts I spent AFTER the chain split are not relevant for the BTG chain? (Meaning I still get the coins in the wallet and they aren't marked as spent immediately....) thx for some clarification here... p.s.: btw, there really hasn't been time enough to seperate the modified bitcoin-qt from the original one? By default using the same folders and basic settings, also not even branding the title or icons - cmon, thats a job an intern can do in one hour... really disappointing...
