client - Bitcoin-Qt setup: Change block-chain file

Cannot find bitcoin.qt data folder, dont know where to put blockchain.dat

Read alot of explanations on the net trying to figure this out and i really have had no luck and need it sorted asap.
Searched for %APPDATA%\Bitcoin and C:\Users\YourUserName\Appdata\Roaming\Bitcoin but theres no bitcoin folder to be found, there is a bitcoin core folder though.
Not sure how to create one if thats what i need to do and really just hoping to get some straight forward help finding where to place this blockchain data and get it up to date asap.
Thanks for any and all help.

Make your own stakebox. Ultimate beginners guide how to compile any wallet on AARCH64 (Raspbery pi and other SBC)

I contemplated to wrote this for a long time, so it's finally time.
As you know a lot of altcoins uses PoS (Proof-of-stake) way of "mining" coins. Which basically means, that you hold coins on your unlocked wallet and you are receiving stakes as a reward. This requires very little power and it can bring you a lot of rewards, at just 10W from the wall.
So first I am using latest Raspbian on RPI4B 4GB in this example.Setting up Raspbian is not part of this process since it's very well documented. I recommend to change user from pi to something else due to security concerns and you can also do other stuff just search "security Raspberry PI" and you find a lot of articles, but this is not the focus of this guide.
I know there are a lot of guides on the internet, but I am using like 5 sources, so it's compiled what other people wrote and some of my research.
I am using AnyDesk insted of SSH or VNC server, because it works it's ligthweit and it just works.
So after you see the gui of Raspbian, just launch terminal (CTRL + ALT + T) and do basic thing:
sudo apt-get update && sudo apt-get upgrade
Than press Y and let it run, after is finished, we need to prepare so dependency packages. Since most of the wallets using Berkeley DB 4.8 we need to obtain it.
So in terminal wrote:
cd cd Downloads wget http://download.oracle.com/berkeley-db/db-4.8.30.NC.tar.gz tar -xzvf db-4.8.30.NC.tar.gz cd db-4.8.30.NC/build_unix ../dist/configure --enable-cxx make sudo make install 
So wait unti it's finished and than you can delete files in Downloads folder in gui or use:
sudo rm -r [folder] 
So next thing we need to install some libraries.
sudo apt-get install git build-essential libtool autotools-dev autoconf pkg-config libssl-dev libcrypto++-dev libevent-dev libminiupnpc-dev libgmp-dev libboost-all-dev devscripts libdb++-dev libsodium-dev 
And pres y and let it run. After that another set of libraries:
sudo apt-get install libqt5gui5 libqt5core5a libqt5dbus5 qttools5-dev qttools5-dev-tools libprotobuf-dev protobuf-compiler libcrypto++- dev libminiupnpc-dev qt5-default 
And then again pres y and let it run. Some wallets need older version of libssl1.0-dev, so for for safe compiling we install that as well:
sudo apt-get install libssl1.0-dev 
Pres y and let it run. Warning don't use sudo-apt get autoremove, since it would wipe this package, since it's old.
Next thing we are going to obtain Bitcoin PPA filest, which can be done like this.
cd /etc/apt/sources.list.d/ sudo nano bitcoin.list 
Paste this in there:
deb-src http://ppa.launchpad.net/bitcoin/bitcoin/ubuntu artful main 
And CTRL+X and than y, then do this:
sudo apt-key adv --keyserver hkp://keyserver.ubuntu.com:80 --recv C70EF1F0305A1ADB9986DBD8D46F45428842CE5E sudo apt-get update 
So now we are ready for compiling. So we are going create folders. CD yourself where this folder should be situated, if you for example have plugged in some external drive. Then:
mkdir Crypto cd Crypto 
And then we have to choose wallet which you want to compile. I am choosing Streamies (STRMS) as an example, since it's pretty good coin for staking. So:
mkdir Streamies cd Streamies 
Then go to the github page and click on the green button on the left and click copy to clipboard, which gives you git link.
git clone https://github.com/Streamies/Streamies.git 
Watch the output folder which it creates, it's stated in the first two lines and copy then by highliting the text and CTRL+SHIFT+C copy it to your clipboard.
cd Streamies (this is that git created folder) ./autogen.sh ./configure CPPFLAGS="-I/uslocal/BerkeleyDB.4.8/include -O2" LDFLAGS="-L/uslocal/BerkeleyDB.4.8/lib" sudo make (this could take hours) sudo make install 
And you are done, files is going to be in folder /uslocal/bin (DO NOT delete git created folder, because you are going to need it for faster compiling, when wallet get's and update.)
cd /uslocal/bin 
Now you can list files by:
ls 
And then you can copy/move them where ever you want by using:
sudo mv * [destination full path] 
Let it run and go back to folder where you move those files.
sudo chmod +x streamies-qt (since we want to run wallet) 
In most cases compiled files are going to in format of "shared library" so we need to create script to run it. Open up a text editor from gui or through nano. And paste this to that file:
#!/bin/bash ./streamies-qt 
And save it as a sh file, for example run.sh. Then we need to make it runnable so:
sudo chmod +x run.sh 
Now to run it, it's just:
./run.sh 
And here we are glorious GUI wallet appears and you are done, you can paste blockchain, wallet.dat from other sources, so this migration is pretty easy and you, if you have it on for exaple flash disk.
So this is basic how to compile QT wallets on AARCH64. I am running 7 wallets, 2 of those are Masternodes and RPI 4B 4GB would handle way more, I am at best on half of my RAM.
Some wallets need more package, but it's not much of and issue, since compiling stops and you just copy paste nape which is missing put it in the google and add "apt-get" after the name of package and you are going to see, what is the name of the packages so it can be retreived from package assinstant aka apt-get. So basically:
sudo apt-get install [package name] 
Then press y and again wrote:
sudo make 
This process is going to continue where it was left off, so nothing is going to run from beginning.
Updating wallets is basically exactly same, just repeat steps from "git clone" and after that proceed as it was written above.
So I hope this helps some of you, to use this at home and not on some VPS, if you are anxious as me, to host my wallets on remote server.

BTC Node. Need help with Ubuntu and BTC core program. To the Linux experts here in reddit.

The good thing of loosing a post, is that you have to retype everything and this means that you are able to shorten the post.
So. TLDR, I have 2 hdd, 80gb and 320, the second one has only, all the Blockchain info, from another already running node. I am not able to tell BTC Core program that the files are already there so he does not need to download 300gb. After hours of Google and linux forums, I am stuck in this issue. Every time I type "bitcoin-qt" on my terminal, it shows as a first download. Any help will be appreciate.

Full story.
English is not my first language, and this is being typed for second time (please have mercy on my grammar or misspelling mistakes), because I posted the question on linux subreddit nobody give a f..... so I decided to bring it here, posted a short post with the link and the automatic bot deleted because the of the link. I erased both the linux and the bitcoin post, and made a third one new, here, with plain text, copy pasting the info from the linux post. Never appeared on the "new" section of this sub. So hours of typing lost, and here we are.
Old Notebook. 80gb drive, and noob to Linux. Although I have some pc and logic knowledge, installed MINT due to a recommendation from a Bitcoin community, but since I have a friend with an already running node, with Ubuntu switched to this one, just to have the same system.
Once Ubuntu installed, on the 80gb and pc running, I copy and pasted the whole bitcoin folder from my friends pc to my 320 gb. Up to here all was good. But here is the problem

My friend, who does not understand nothing about linux, is owner of a company and has an IT guy who made everything for him, but would not be willing to help me a lot, (just to be good with his boss but right now it is not reachable for me), but when we where on my pc he told me that Linux is very sensitive to ports, in other words, a small usb change, will do a program to loose the path for the files. SO, instead of using the 320gb disk on USB i installed on this notebook second Hdd bay (its an old high end laptop with 2 sata connectors), he was able to set the program and everything went well for a couple of hours, Bitcoin Core program started synchronizing, downloading very little info.

I needed to turn of the pc to move it, so closed the program (waited until bitcoin core program told me was safe to) and turn it off, then turn it on again, and the problem was there, bitcoin core program started trying to download the whole blockchain in the spare 2gb of the 320 gb disk.
So what it seemed to happen is that even when the disk is installed on a sata bay from the motherboard, as I did not installed ubunutu with this disk connected it's route (adress?) is dinamyc and that is why BTC Core Program lost the files and does not recognize it.
After hours of google, linux forums and "askubuntu" i was able to, mount the 320gb disk, first editing the fstab ( i followed the guide in "askubuntu.com/questions/125257/how-do-i-add-an-additional-hard-drive") by the way. Trying to use VIM editor was a pain, it is REALLY difficult to type something there, and save it without pressing a wrong key. I had to cancel and start over at least a dozen times (plus reading several guides), but still was not able to mount the disk (Actually after following the steps, the hdd (320) disappeared from the GUI). went back, erased, and the did the NANO steps, and I THINK that now the hard drive it is fixed (before, any change,when restarting the second hdd took some time to appear, now it seems that is mounted and to a fixed adress). Well, after mounting the hdd, I tryed to call the bitcoin-qt and the initial download page appear and again tries to download from the initial block. I searched over hours "file association in ubuntu", "program files path" etc etc and the only thing I found is how to set up the desired software to open a file.

For you to understand my mess, when I did the "user:user" thing, I did not understand completely what I was doing, (yes I had to be in sudo) BUT i think I managed to did the correct thing as both hdd are shown in the Ubuntu GUI.

Some additional data is
Both hard drives are formated in Ext4
I have (I think that) a fstab.bak before any changes

I knwo that linux users sometimes ask for details on the system, just tell me the commands and i can run them to stick any info needed.

Thanks for the help in advance.

(Updated) [Staking] Reddcoin Core client GUI wallet on a Raspberry Pi Model 3B

Intro

This thread is an update to my first Reddcoin staking tutorial that was written 7 months ago.
 
The reason for the update
My Reddcoin Core software crashed and became unusable. My Raspberry Pi 3B would lag and freeze, I couldn't stake anymore.
 
Instead of just redoing everything the same way, I wanted to see if I could improve on 3 points:
 
The updates
 
If you would like to tip me
Writing a tutorial like this takes time and effort; tips are appreciated. My Reddcoin address: RqvdnNX5MTam855Y2Vudv7yVgtXdcYaQAW.

Backup
Backup your wallet to prevent losing the RDDs in your wallet! There are two methods to backup, do both. Make new backups if you create a new receiving address!
 
 
   
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.
   
Connection issues If you have issues syncing the blockchain because you have 0 network connections, please follow the instructions in this thread.
   
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.
   
Minimization options
Adjust minimization options, so you can safely press on the X button (the close/exit button on the upper right corner).
   
RealVNC VNC Viewer (client) and VNC Connect (server): To remote connect to the Raspberry Pi, I use VNC Viewer ad VNC Connect from RealVNC.
 
   
Chromium as browser: The updates break Firefox, the browser crashes when you try to run it. Install another browser, Chromium, to solve this issue.
   
Updates / Upgrades
If Software Updater shows up and tells you that there is updated software available, do not install the updates using Software Updater. Use LXTerminal to update Lubuntu.

The linux version of bitcoin qt (0.8.5) is not robust

I've tried about 4 times to download the blockchain. Twice, the database has become corrupted. Another time it gave an error "failed to connect best block". And while it is catching up, it seems to sometimes just stall for a while.

Bitcoin-qt crashes when starting up

I've been trying to run Bitcoin-qt today without success. I've tried the obvious things, like restarting my computer, but that's about the limit of what I can think of to try.
Does anyone have suggestions? I'm on Mac, running OS X 10.7 Lion. And if it can't be fixed, can anyone recommend an alternative client?

Help, My backup says its corrupted!

Ok, I finally found my back up from 11-12-12. I try to use it in mutilbit and bitcoin-QT. It was originally made with bitcoin-qt, but that says its corrupted. I have tried to install pywallet, I must not be reading something right, because it's not working. I'm on Win7 64. I really don't want to lose at least 2 BTC. Any help for a noob? If it helps it's a .dat file about 672kb in size.

WolfCoin Wallet

The Wolfcoin blockchain and network are both designed and engineered to ensure store of value, transactional speed and security, and fungibility. The main goal of the Wolfcoin blockchain is to facilitate fast and secure transactions with a governance that helps sustain the network for the benefit of all users. The Wolfcoin blockchain is a two-tier network comprised of a Proof of Work (PoW) consensus mechanism powered by miners and a Proof of Service (PoSe) system powered by masternodes. Miners receive rewards for ensuring the security of the blockchain and masternodes are rewarded for facilitating the features of the network including Private Send and Instant Send. Wolfcoin uses the X11 hashing algorithm and is based on the Bitcoin Core codebase version 0.12.
  1. Download the Wolfcoin Wallet. Place the Wolfcoin Wallet zip file on your desktop, and extract all of the files on your desktop. Open the new Wolfcoin Wallet Folder. And run the the Wolfcoin QT File. The wallet will now load and start downloading the Blockchain and syncronizing with the Wolfcoin Network.
  2. Once the Wolfcoin Wallet is fully synchronized, you're Wolfcoin Wallet is now ready, and fully installed. Please click on Settings and then Encrypt Wallet. Create your password or passphrase, and save it somewhere safe as if you lose it, you'll lose all of your Wolfcoins as well. The wallet will now close down, and please reopen it.
  3. Once you've restarted the Wolfcoin Wallet, and it's fully synchronized again, now click on File and click on Backup Wallet. Save the file as 'wallet.dat', and save it in a folder named Wolfcoin Wallet. Please save this folder and file on a USB, or another HD for safe keeping as this file is your wallet and all of your Wolfcoins. Your Wolfcoin Wallet is now ready, backed up, encrypted, and ready to be used.

[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! If anyone wants to add/fix/correct anything in this message, please send a message to the mods <<-- Click blue text.

A very important message/reminder below.
25 Jan 1.5 pre-releases have started.
http://www.reddit.com/dogecoin/comments/1uhpwf/dogecoin_for_mac_14_topic_thread/
OLD VERSIONS The 1.4 update for the dogecoin wallet has been released. This update addresses the block chain error that occurred. This update is mandatory meaning you have to do this update. Also further down the page you can read up about the block chain. You MUST make sure you're on the correct block chain and the old block chain has been removed.
For a Windows computer the version must be 1.4. - 1.4.1 just released! See below
For a Apple Mac Computer the version must be 1.4
Download links:
[Windows Download Link](https://github.com/dogecoin/dogecoin/releases/download/1.4/dogecoin-qt-v14-Win.zip) <<--Click to start download

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
*Note the example numbers in the pictures might be out of date by the time you read them
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.
Much Thanks. 
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.

[Staking] Reddcoin Core client GUI wallet on a Raspberry Pi Model 3B

This tutorial has been updated: https://www.reddit.com/reddCoin/comments/a0wn1v/updated_staking_reddcoin_core_client_gui_wallet/.
   

Intro

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.

Run a 0.14 Full-Node on RaspberryPi3 Pruned(less than 16GB SD needed)

Hi!
Happy if this guide helps you.
Tip if you want: 19656Uwdwko5RjtnuwQENpjBwE3ChzD59v
UPDATE 04/06/17
Add 'uacomment=UASF-SegWit-BIP148' into your bitcoin.conf if you want to signal UASF.
UPDATE 03/13/17
ADDED a tl;dr; Version at the end of this Post.
UPDATE 03/12/17:
Just to test it - I reinstalled all on 8GB SD and it works as well. But maybe you should use at least 16GB for the beginning.
Using a 128GB card for the first version was a little bit stupid - so I reinstalled everything on a 8GB SD card. Including Linux and a pruned blockchain - and it works.
I used prune=550 and Jessie Lite (headless / command line) - without wallet and gui.
The SD is almost full, but it works so far
I also updated the whole manual a bit to make things more clear. Thank you for all your feedback!
Just started my Bitcoin Node today and wanted to share the way I did it with people who are interested in running their own full node. It took some time to write everything down - hopefully correct so far.
I am sure, many people around bitcoin are way more informed and educated as I am - I am the noob. So I wrote this manual to help users like me - noobs, to get started with a cheap, simple bitcoin node on raspberry pi.
Have fun!
I wanted to get my Raspberry Pi 3 working as a node to support the network. Actually the process of installing and running the node was more or less easy - but for Noobs (like I am) it might be a bit tricky to start the whole thing, because there are different ways.
Did you - like me - think you would need +120GB on the raspi, external USB HDD to be a full node? You won't!
If you have a Raspberry and you know what Bitcoin is, I guess, you are a little bit aware of linux, networks and of course bitcoin - so I won't go into detail too much.
This guide is just a little helper to get a full node running on your raspberry pi. Thanks to the help of the nice people in this sub and of course the documentation by the developers, I got it working - and of course also special thanks to raspnode.com - as I followed their tutorial to start - I went some other ways here and there - so please read carefully.
For the Part 2 I would suggest to have http://raspnode.com/diyBitcoin.html open and read through my manual.
I split the tutorial in 2 Parts - PART ONE is about installing the client on your PC and downloading the Blockchain.
PART TWO is about the setup of the raspberryPi and transferring the pruned blockchain to the pi and run it as a full node!
The first thing to be aware of is: You actually need to download the whole blockchain to get this working - if you already have your bitcoin client synced on the PC / MAC great you can reuse it!
Now you might think "but you said less than 16GB in the title!"
Yes, but the good thing is you won't need to download it on your Raspberry, neither you need to sync it completely on your raspberry which took ages (weeks!) before. When you finished this Guide, you will just have a max. 4GB Blockchain on your Raspberry Pi - but it still is a full node! The magic word is Pruning.
Maybe even a 8GB SD Card works just fine including Linux (jessie lite)!
So, if you already have a full node on your PC - Great you can almost skip PART ONE - BUT have at how to Prune in PART ONE if you don't know about it.
For PART TWO you'll need a Raspberry Pi 2 or 3 (I used 3) min. 8GB (works also) or better 16GB SD Card. (I used a 128GB for the first version of this manual - which is way too big)

PART ONE

This is the manual how to get started on you PC / MAC / Linux (I did it on Win7)
Go to: https://bitcoin.org/en/download and download the core Client for your Machine (I used win64).
Install it and configure it to save the Blockchaindata to the directory of your choice - so instead getting 120GB on your C drive, I would suggest to download it to another place like a USB drive.
You can set this up during the install. Standard folder for the blockchain folder is "%APPDATA%\Bitcoin" on Windows.
or you can do it after the install by creating a bitcoin.conf file inside your installation folder / or %APPDATA%\Bitcoin and add
datadir=l:\yourfolder
to the file. Line by line.
By the way here you could also just add dbcache - to use more memory to speed up the process a bit:
dbcache=4096
if you don't want to use the settings inside the program. (you can also set this inside the program under settings! If you have this inside the bitcoin.conf you will see the amount you set there from inside the program - it overrides the values)
You can check inside the windows client under settings, if you can see a manual dbcache is set by having a look at the left footer area. When your dbcache value shows up, everything is fine.
So the Blockchain download process will take time - maybe a few days! Depending on your machine, internet connection and HDD.
The Blockchain is huge as it contains every single transaction of the past until today. You won't need to keep your PC running all the time, you can turn it off and on and it will resync automatically when you start bitcoin-qt.exe!
Make sure to close the client always via "quit" - ctrl+q.
After you have your bitcoin core installed, the blockchain downloaded and synced - you are ready to PRUNE!
First - close the Client and let it close smoothly. After it is really closed you can follow these steps:
By pruning, your blockchain will dramatically shrink. From 120GB to just a few GB.
Be aware, that you will lose your Downloaded Blockchain as pruning will erase a big chunk of it! If you have enough space, you could of course keep the full blockchain saved somewhere on another HDD.
You can prune by editing your bitcoin.conf file by adding:
prune=550
I used prune=1024 - not sure where the differences are right now (min. prune=550). (for my 8GB version I used 550! I suggest to use this.)
Save the bitcoind.conf file and restart your windows client.
It will now clean up the Blockchain. So just the latest blocks are saved. The client should start without any problems. Maybe it takes some time to prune the blockchain data.
Check if everything works normally (the client opens as usual, you can see an empty wallet) than close the client.
Inside the Bitcoin Folder, you'll find two folders called:
blocks chainstate
those are the interesting folders containing the important data (now pruned) - and we will transfer those two to the raspberry later!
Now you are good to start the raspi transfer explained in the next part.

PART 2

Here is what I did:
1) I installed Raspian Pixel (https://www.raspberrypi.org/downloads/raspbian/) using a 128 GB SD - which is not needed because of "Pruning" - I think a 16GB card might work, too! (You can also install Raspian Jessie Lite - which saves you even more space, as it runs headless - only command line) (Updated: It is better to use Jessie Lite to save a lot of space - when you are fine with only command line)
2) I followed partly this tutorial to get everything running and setup:
http://raspnode.com/diyBitcoin.html
Please have a look at it - I have copied the Headlines in capitals to let you know what I did, and what I skipped.
On Tutorial Page: Start with RASPBIAN (OPTIONAL) CONFIG OPTIONS.
Set You RasPi up including "EDITING FILES" to save your Layout at the tutorial page and come back here.
I skipped the CONFIGURE USB AND SET AUTOMOUNT process, as we are going to use PRUNING to reduce the 120GB to a tiny filesize - so USB Devices are not needed here!
It was necessary to ENLARGE SWAP FILE to install bitcoin core - otherwise it didn't went through which ended in a frozen raspi.
So have a close look by following the raspnode tutorial at: ENLARGE SWAP FILE.
I have my raspi running via cable to router - but you can also WiFi setup everything described under NETWORKING ON THE RASPBERRY PI.
Now comes the interesting part: Follow the steps at DOWNLOADING BITCOIN CORE DEPENDENCIES - they work fine for 0.14.0 too. Git should be on Board already when you installed Pixel - otherwise you would need to install it.
sudo apt-get install git -y (only jessy lite)
I skipped the next command lines - as I don't use bitcoin-qt wallet. If you want to use it as wallet - do the step.
mkdir ~/bin cd ~bin
Now you are in the folder you want your bitcoin core data be downloaded to via git. I didn't Downloaded the Berkeley Database source code - so I also skipped the whole next command lines
[email protected]~/bin$ wget http://download.oracle.com/berkeley-db/db-4.8.30.NC.tar.gz [email protected]~/bin$ tar -xzvf db-4.8.30.NC.tar.gz [email protected]~/bin$ cd db-4.8.30.NC/build_unix/ [email protected]~/bin/db-4.8.30.NC/build_unix$ ../dist/configure --enable-cxx [email protected]~/bin/db-4.8.30.NC/build_unix$ make -j4
and went on with "INSTALLING BITCOIN"!
I followed the first part but instead downloading 0.13 I took of course the latest version:0.14
git clone -b 0.14 https://github.com/bitcoin/bitcoin.git cd bitcoin ./autogen.sh
this might take some time to start.
If you have trouble with hanging RESOLVING DELTAS - just restart the Raspberry Pi and remove the bitcoin folder inside /~bin using
rm -rf bitcoin
this command will delete the folder and you can reuse
git clone -b 0.14 https://github.com/bitcoin/bitcoin.git

For some reason RESOLVING DELTAS is a common problem with different downloads - so just retry it and at least after 3 times it should work!

as I didn't use the GUI/ Wallet, I ran
./configure --enable-upnp-default --disable-wallet
as I don't need the wallet functionality.
I didn't need to use "MAKE" which saves you maybe up to 2.5 hours.
instead you can just go ahead with:
sudo make install
(If I am wrong in doing so - please let me know)
The install takes some time - and just a heads up: when it gets stuck somewhere - just redo the installation process - it took three times to went through - stuck at some processing.
After the installation took place you can finally get your Raspberry Pi Node running in no time!
To test if the the installation went through - you can just start bitcoind using:
bitcoind &
than check if everything is working so far:
bitcoin-cli getinfo
after a few seconds you should see version: etc...
if not, something went wrong. Try to redo the steps in the raspnode tutorial.
(don't give up if it failed - retry! Ask your questions here)
IMPORTANT: you need to stop bitcoin on your raspberry now!
bitcoin-cli stop
If you don't need an external USB Drive - what I hope - as we are going to use pruning just go ahead and skip the USB part and create a file inside (or follow the raspnode tutorial on how to setup the USB drive):
cd .bitcoin
sudo nano bitcoin.conf
and enter the exact same pruning size you have used on your Desktop Machine to prune. I used 1024 but the minimum is 550. (used 550 for the 8GB SD card on PC and Raspberry)
prune=550
That's it for the raspi.
update: To signal UASF enter in a new line:
uacomment=UASF-SegWit-BIP148

TRANSFER

Now you have to transfer the two folders CHAINSTATE and BLOCKS from your PC bitcoind directory to your raspberry.
I am using a program called "WINSCP" - it is free and easy to use: https://winscp.net/eng/download.php
We need this to transfer the files to the Raspberry pi. Pretty sure you can also do it via SSH - but I am the noob. So let's keep it simple.
Open Winscp and put in the IP Address of your Raspberry Pi, User and Password (same as in SSH)
You should now see the directories on your Raspberry Pi. There is a folder called
.bitcoin
enter it and you will see the two folders
blocks & chainstate
you can delete them on the raspberry as they have some data from your previous test inside.
Make sure you can also see the bitcoin.conf file in that directory, which needs to contain the exact same prune line, like the one on your desktop machine. If not, make sure to edit it via SSH. The line "datadir=l:\yourfolder" is obviously not needed in the Raspberry bitcoin.conf file.
Now grab the two folders CHAINSTATE and BLOCKS from your PC and copy them to your .bitcoind folder.
I also copied banlist.dat, fee_estimation.dat, mempool.dat and peers.dat to the folder - not really knowing if needed! Not needed.
The whole copy process might take some minutes (against some weeks in the old way).
After copying is finished, you can now start bitcoind on the Raspberry.
bitcoind &
the & symbol let you still use the command line while the process is running btw.
The process - if succesfull - will take some time to finish.
bitcoin-cli getinfo
Will give you some informations what is going on right now. When you can see, that it is checking the blocks, this is good!
If you get an error - double check - if you have the correct prune size (same as on desktop machine) - in bitcoin.conf and that this file is inside .bitcoin on RaspberryPi. It took me some time, to find my mistakes.
Congrats! You are almost a part of the network!
To make your node now a fullnode, you will need to go to your router (often 192.168.1.1) and enable portforwarding for your raspberry pi - and open ports 8333 - that's it!
You can now go to: https://bitnodes.21.co/nodes/
scroll down to "JOIN THE NETWORK" and check check if your node IP is connected!
It will show up as soon as the blocks are checked and the raspi is running.
Well done!
Now you are running a full node, with a small Blockchain and got it working in Minutes, not weeks!
I really hope, my little tutorial worked for you and your are part of the Node network now.
If you have problems or I made a mistake in this helper tut, just let me know and I will try to make it better.
Have fun and NODL!
the noob
tl;dr; (if you are a real noob start with the non-tl;dr version!)
tl;dr; PART ONE
1) Download & install / setup bitcoincore @ https://bitcoin.org/de/download
2) change dbcache to something smaller than your memory and download the whole Blockchain (120GB).
3) create a file called bitcoin.conf put the line prune=550 (or higher) in to activate pruning on win inside %appData%/bitcoin
4) Open ports 8333 on your Router to make this a full node with a smaller Blockchain.
You are running a full node on your PC.
tl;dr; PART TWO
1) Install jessie lite and the needed dependencies on your SDCard - Raspberry
( >git clone -b 0.14 https://github.com/bitcoin/bitcoin.git )
  • see tutorial for more info.
2) create a file called bitcoin.conf inside .bitcoin and add the same prune=Number you had on your PC.
3) transfer the pruned folders BLOCKS and CHAINSTATE to the Raspberry Folder .bitcoin
4)Start "bitcoind &"
5) let everything sync
6) Make sure you have port 8333 opened on your router.
You are running a full node on your Raspberry with a super small Blockchain (I put all on a 8GB SDcard)

such beginner shibe thread wow how to get coin

 how to shibecoin v rich in minutes much instruct so simple any doge can do 

START HERE

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:
maxconnections=100 addnode=95.85.29.144 addnode=162.243.113.110 addnode=146.185.181.114 addnode=188.165.19.28 addnode=166.78.155.36 addnode=doge.scryptpools.com addnode=doge.netcodepool.org addnode=doge.pool.webxass.de addnode=doge.cryptopool.it addnode=pool.testserverino.de addnode=doge.luckyminers.com addnode=doge.cryptovalley.com addnode=miner.coinedup.comdoge addnode=doge.cryptoculture.net addnode=dogepool.pw addnode=doge.gentoomen.org addnode=doge.cryptominer.net addnode=67.205.20.10 addnode=162.243.113.110 addnode=78.46.57.132 
And paste it into a new text file called dogecoin.conf, which you then place into the dogecoin app directory.
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!

GETTING COINS

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

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.

GPU MINING

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: You can mine in two ways. Solo mining is where you mine by yourself. When you find a block you get all the reward. Pool mining is when you team up with other miners to work on the same block together. This makes it more likely that you'll find a block, but you won't get all of it, you'll have to split it up with others according to your share of the work. Pool mining is recommended because it gives you frequent payouts, because you find more blocks. The larger the pool you join, the more frequent the payouts, but the smaller the reward you get.
Over a long period of time the difference between pool and solo mining goes away, but if you solo mine it might be months before you get any coins.

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:
When you're done with this, you'll need to know:

Step three: Download mining software

For best performance you'll need the right mining software.
Unzip the download anywhere you want.

Step four: Set up miner

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: A normal hashrate is between 50 Kh/s up to even 1 Mh/s depending on your GPU.

You're now mining Dogecoins

That's it, nothing more to it.

CPU MINING

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

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

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!

Begging

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.

Tips

At the moment there are two tip bots:
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.

TESTNET Preparation

Ravencoin was launched on January 3, 2018, as a free, open source platform forked from the Bitcoin codebase. Since that time, Ravencoin has operated as a fully functional network based on the Bitcoin UTXO model. All coins have been fairly mined by a decentralized network of miners using the ASIC-resistant X16r algorithm.
Since the launch, developers have been actively working to add additional asset creation functionality to the Ravencoin core wallet client, as contemplated by Phase 2 (asset support) of the Ravencoin roadmap here.
The Ravencoin community is now able to run the current core Ravencoin client in testnet mode, in order to generate addresses that will be able to receive testnet RVN. On July 30, new asset layer features will be added to the core wallet client for use on Ravencoin’s test network. These features are expected to include additional capabilities that will facilitate the native creation, issuance and transfer of asset tokens. A revised version of the core client software will be made available for download on GitHub. This will allow for rigorous community testing of the native asset layer functionality — including the creation and issuance of testnet assets — in contemplation of the anticipated launch of this functionality on the mainnet in October.
This testnet network will be a completely independent secondary blockchain for testing purposes only, in which all tokens will have no intrinsic value and will not be traded on exchanges. The purpose of a testnet is to test features and functionality before introducing those features and functionality to the main blockchain. It is a playground to experiment and test different features with almost no cost to transact or mine blocks. During this testing phase, the Ravencoin blockchain itself will continue to maintain the same operation and functionality it has today.
To run your current wallet in testnet mode:
  1. First shutdown your current full client wallet.
  2. Create a shortcut to your raven-qt.exe with this in the target field: C:\Users\Path\to\executable\raven-qt.exe" –testnet
  3. Open the wallet by clicking on the shortcut you just made, and let the blockchain sync fully
Don't worry, this will not interfere with your regular Raven wallet, just make sure both wallets are not running at the same time. For those who are technically inclined, running in testnet mode does not overwrite any of the blockchain data or wallet files of Ravencoin’s main network. Instead, it will create a subfolder named testnet3 inside your data folder where all testnet related data and wallets reside. If you would prefer to err on the side of caution, consider running your testnet wallet on a different computer.
There are currently a couple of tools available to assist you with testnet testing.
After this testing period, it is anticipated that the community will consider adoption of the new asset-aware code. Activation will occur through the BIP9 consensus mechanism. More information on the activation process can be found here.

Please help - why is my Bitcoin Conf file in the wrong directory?

I am running a Bitcoin Core GUI-based full node on Windows 10. The conf file is in my bitcoin data directory, instead of being in the appdata/roaming folder. But bitcoind and bitcoin-cli continue to look for the conf file in that appdata/roaming folder, which I guess is the reason the bitcoind server never appears to start. However, Bitcoin-qt (the GUI) appears to work fine and is also pointing to the conf file correctly. I checked by opening the conf file from the settings>options.

How do I start bitcoind and check if it is running or not? If I run it on cmd, it appears to start downloading the whole blockchain again, which is unnecessary because I already have all of it.

Transcript from Ravencoin Open Developer Meeting - Nov. 16, 2018

Tron at 2:03 PM

Topics: Messaging (next phase) UI 2.2 - Build from develop - still working out a few kinks Mobile - Send/Rcv/View Assets - In progress Raven Dev Kit -Status

RavencoinDev at 2:04 PM

Hey Everybody! Let's get started!Thanks Tron for posting the topics.Tron is going talk about Messaging Plans.Let's start there.

Chatturga at 2:06 PM

It looks like this channel is not connected to the IRC. One moment

RavencoinDev at 2:07 PM

Well, we going to move forward as the tech guys fix the IRC connections.

Tron at 2:07 PM

I wanted to have a doc describing the messaging, but it isn't quite ready.I understand this isn't going to IRC yet, but I'm starting anyway.

RavencoinDev at 2:08 PM

Look for it soon on a Medium near you.

Tron at 2:08 PM

Summary version: Every transaction can have an IPFS hash attached.

Vincent at 2:09 PM

any plans for a 'create IPFS' button?

RavencoinDev at 2:09 PM

Yes

Vincent at 2:09 PM

on asset creatin window also?

RavencoinDev at 2:09 PM

Yes

Vincent at 2:09 PM

sweet

Tron at 2:09 PM

IPFS attachments for transactions that send ownership token or channel token back to the same address will be considered broadcast messages for that token.The client will show the message.Some anti-spam measures will be introduced.If a token is in a new address, then messages will be on by default.The second token in an address, the channel will be available, but muted by default.

RavencoinDev at 2:11 PM

That way I can't spam out 21b tokens and then start sending messages to everybody.

Tron at 2:11 PM

We'd like to have messaging in a reference client on all six platforms.

corby at 2:11 PM

Hi!

Tron at 2:11 PM

Photos will not be shown. Messages will be "linkified"

RavencoinDev at 2:12 PM

and plain text.We'll start with the QT wallet support

Tron at 2:12 PM

Any other client is free to show any IPFS message they choose.The messaging is fully transparent.

Rikki RATTOE at 2:13 PM

ok, so messaging isn't private

Tron at 2:13 PM

Anyone could read the chain and see the messages.

RavencoinDev at 2:13 PM

No, never was planned to be private

MSFTserver-mine more @ MinerMore at 2:13 PM

irc link should be fixed

Tron at 2:13 PM

It is possible to put encrypted content in the IPFS, but then you'd have to distribute the key somehow.

RavencoinDev at 2:13 PM

Thanks MSFT!

Chatturga at 2:13 PM

Negative

Tron at 2:14 PM

Core protocol changes Extend the OP_RVN_ASSET to include for any transfer: RVNT <0xHH><0x12><0x20><32 bytes encoding 256 bit IPFS hash> 0xHH - File type 0x00 - NO data, 0x01 - IPFS hash, 0x02 through 0xFF RESERVED 0x12 - IPFS Spec - Using SHA256 hash 0x20 - IPFS Spec - 0x20 in hex specifying a 32 byte hash. …. (32 byte hash in binary)

corby at 2:14 PM

By it's nature nothing on chain is private per se. Just like with wallets you'd need to use crypto to secure messaging between parties.

Tron at 2:14 PM

Advantages: This messaging protocol has the advantage of not filling up the blockchain. The message information is public so IPFS works as a great distributed store. If the messages are important enough, then the message sender can run nodes that "PIN" the message to keep a more durable version. The message system cannot be spoofed because any change in the message will result in a different hash, and therefore the message location will be different. Only the unique token holder can sign the transaction that adds the message. This prevents spam. Message clients (wallets), can opt-in or opt-out of messages by channel. Meta-message websites can allow viewing of all messages, or all messages for a token. A simple single channel system is supported by the protocol, but a channel could be sub-divided by a client to have as many sub-channels as desired. There are no limits on the number of channels per token, but each channel requires the 5 RVN fee to create the channel.

RavencoinDev at 2:14 PM

So, somebody could create their own client and encrypt the data on the blockchain if they wished.

corby at 2:15 PM

Wow Tron types fast

Rikki RATTOE at 2:15 PM

yeah there was some confusion in the community whether messaging would be private and off chain

Tron at 2:15 PM

Anti-Spam Strategy One difficulty we have is that tokens can be sent to any Ravencoin asset holder unsolicited. This happens on other asset platforms like Counterparty. In many cases, this is good, and is a way for asset issuers to get their token known. It is essentially an airdrop. However, combined with the messaging capabilities of Ravencoin, this can, and likely will become a spam strategy. Someone who wants to send messages (probably scams) to Ravencoin asset holders, which they know are crypto-savvy people, will create a token with billions of units, send it to every address, and then message with the talking stick for that token. Unless we preemptively address this problem, Ravencoin messaging will become a useless spam channel. Anyone can stop the messages for an asset by burning the asset, or by turning off the channel. A simple solution is to automatically mute the channel (by default) for the 2nd asset sent to an address. The reason this works is because the assets that you acquire through your actions will be to a newly generated address. The normal workflow would be to purchase an asset on an exchange, or through a ICO/STO sale. For an exchange, you'll provide a withdrawal address, and best practice says you request a new address from the client with File->'Receiving addresses…'->New. To provide an address to the ICO/STO issuer, you would do the same. It is only the case where someone is sending assets unsolicited to you where an address would be re-used for asset tokens. This is not 100% the case, and there may be rare edge-cases, but would allow us to set the channels to listen or silent by default. Assets sent to addresses that were already 'on-chain' can be quarantined. The user can burn them or take them out of quarantine.

RavencoinDev at 2:18 PM

Okay, let me know when/if you guys read through all that. 📷📷2

corby at 2:18 PM

To be clear this is a client-side issue -- anyone will be able to send anything (including messages) to any address on chain..

RavencoinDev at 2:18 PM

It'll be in the Medium post later.

Tron at 2:19 PM

@corby The reference client will only show messages signed by the issuer or designated channels.Who is ready for another wall of text? 📷

corby at 2:19 PM

I hear that's the plan 📷 just pointing out that it is on the client in these cases..

Tron at 2:20 PM

Yes, any client can show anything gleaned from the chain.Goal: A simple message format without photos. URL links are allowed and most clients will automatically "linkify" the message for valid URLs. For display, message file must be a valid json file. { "subject":"This is the optional subject", "message": "This is required.", "expires": 1578034800 } Only "message" is required {"message":"Hello world"}

bhorn at 2:21 PM

expires?

Vincent at 2:21 PM

discount coupon?

Tron at 2:21 PM

If you have a message that worthless (say after a vote), just don't show the message.

bhorn at 2:21 PM

i see - more client side operation

corby at 2:21 PM

/expires

Tron at 2:22 PM

Yep. And the expiration could be used by IPFS pinners to stop worrying about the message. Optional

RavencoinDev at 2:22 PM

If the client sees a message that is expired it just won't display it.

Vincent at 2:23 PM

will that me messaged otherwise may cause confusion?"expired'

RavencoinDev at 2:23 PM

YesWe'll do our best to make it intuitive.

Tron at 2:24 PM

Client handling of messages Pop-up messages or notifications when running live. Show messages for any assets sent to a new address - by default Mute messages for assets sent to an address that was already on-network. Have a setting to not show messages older than X IPFSHash (or 8 bytes of it) =

Rikki RATTOE at 2:25 PM

will there be a file size limit for IPFS creation in the wallet?

RavencoinDev at 2:25 PM

We'll also provide updated documentation.

Tron at 2:26 PM

Excellent question Rikki. Here are some guidelinesGuidelines: Clients are free to show or not show poorly formed messages. Reference clients will limit message display to properly formed messages. If subject is missing, the first line of the message will be used (up to 80 chars). Standard JSON encoding for newlines, tabs, etc. https://www.freeformatter.com/json-escape.html Expiration is optional, but desired. Will stop showing the message after X date, where X is specified as Unix Epoch. Good for invites, voting requests, and other time sensitive messages that have no value after a specific date. By default clients will not show a message after X blocks (default 1 year) Amount of subject shown will be client dependent - Reference client may cut off at 80 chars. Messages longer than 15,000 (about 8 pages) will not be pinned to IPFS by some scanners. Messages longer than 15,000 characters may be rejected altogether by the client. Images will not be shown in reference clients. Other clients may show any IPFS content at their discretion. IPFSHash is only a "published" message if the Admin/Owner or Channel token is sent from/to the same address. This allows for standard transfers with metadata that don't "publish".Free Online JSON Escape / Unescape Tool - FreeFormatter.comA free online tool to escape or unescape JSON strings

RavencoinDev at 2:26 PM

We're hoping to add preferences that will allow the user to customize their messaging experience.

Tron at 2:27 PM

Also, happy to receive feedback from everyone.

corby at 2:27 PM

In theory though if you maintain your own IPFS nodes you should be able to reference files of whatever size right?

Steelers at 2:27 PM

How about a simple Stop light approach - Green (ball) New Message, Yellow (Ball) Expiring Messages, Red (Ball) Expired Messages

RavencoinDev at 2:27 PM

Yes please! That's the point of sharing it here

RavencoinDev at 2:29 PM

Questions on messaging?

Jeroz at 2:30 PM

Not sure if I missed it, but how fast could you send multiple messages in succession?

BruceFenton at 2:30 PM

Some kind of sweep feature or block feature for both tokens and messages could be useful Certain messages will be illegal to possess in certain jurisdictions If someone sends a picture of Tiennneman tank man in China or a message calling for the overthrow of a ruler it could be illegal for someone to have There’s no way for that jurisdiction to censor the chain So some users might want the option to purge messages or not receive them client side / on the wallet

Tron at 2:30 PM

Messages are a transaction.

RavencoinDev at 2:30 PM

So it'll cost you to spam messages.They can only send a hash to that picture and the client won't display anything not JSON

corby at 2:31 PM

purge/block is the age old email spam

Tron at 2:31 PM

The Reference client - other clients / web sites, etc can show anything they wish.

RavencoinDev at 2:31 PM

You can also burn a token if you never want to receive messages from that token owner.

UserJonPizza|MinePool.com|Mom at 2:32 PM

Can't they just resend the token?

Tron at 2:33 PM

Yes, but it would default to mute.📷2

RavencoinDev at 2:33 PM

meaning it would show up in a spam foldetab

bhorn at 2:33 PM

is muting available for the initial asset as well?

RavencoinDev at 2:33 PM

Something easy to ignore if muted.

Tron at 2:33 PM

@bhorn Yes

BruceFenton at 2:33 PM

Can users nite some assets and not others?

Tron at 2:33 PM

@bhorn It just isn't the default.

BruceFenton at 2:33 PM

Mute

RavencoinDev at 2:33 PM

YesYou can mute per token.

BruceFenton at 2:34 PM

Great

Tron at 2:34 PM

And per token per channel.

Jeroz at 2:34 PM

channels are the subtokens?

BruceFenton at 2:34 PM

What’s per token per channel mean ?

Tron at 2:34 PM

The issuer sends to the "Primary" channel.Token owner can create channels like "Alert", "Emergency", etc.These "talking sticks" are similar to unique assets.📷1ASSET~Channel

RavencoinDev at 2:37 PM

Okay, we have a few more topics to cover today.Tron will post more details on Medium and we can continue discussions there.

Jeroz at 2:38 PM

Ah, I missed channel creation bit for each token with the 5 RVN / channel cost. It makes more sense to me now.

RavencoinDev at 2:38 PM

The developers are working towards posting a new version 2.2 that has the updated UI shown on twitter.

Vincent at 2:39 PM

twit link?

RavencoinDev at 2:39 PM

The consuming of large birds (not ravens) might slow the release a bit.So likely the week after Thanksgiving.

[Dev] Blondfrogs at 2:39 PM

The new UI will contain: - New menu layout - New icons - Dark mode - Added RVN colors

Dan1666 at 2:39 PM

+1 Dark mode

RavencoinDev at 2:39 PM

DARK MODE!

Dan1666 at 2:40 PM

so pleased about that

RavencoinDev at 2:40 PM

I can honestly say it'll be the nicest crypto wallet out there.

[Dev] Blondfrogs at 2:40 PM

A little sneak peak, but this is not the final project📷📷6📷3

!S1LVA | MINEPOOL at 2:40 PM

Outstanding

Dan1666 at 2:41 PM

reminds me of Sub7 ui for those that might remember

UserJonPizza|MinePool.com|Mom at 2:41 PM

Can we have an asset count at the top?

[Dev] Blondfrogs at 2:41 PM

Icons will be changing

Vincent at 2:41 PM

does the 'transfer assets' have a this for that component?

Tron at 2:41 PM

Build from develop to see the sneak preview in action.There may be small glitches depending on OS. These are being worked on.

Rikki RATTOE at 2:41 PM

No plans for the mobile wallet to show an IPFS image I'm assuming? Would be a nice feature if say a retail store could send a QR coupon code to their token holders and they could scan the coupon using their wallet in store

[Dev] Blondfrogs at 2:42 PM

@Vincent That will probably be a different section added later📷1

RavencoinDev at 2:42 PM

Yes, Rikki we do want to support messaging.Looking into how that would work with Apple and Google push.

push | ravenland.org at 2:42 PM

sub7📷1hahaoldschoolit so is similar aswell

[Master] Roshii at 2:43 PM

Messages are transactions no need for any push

Tron at 2:43 PM

@Rikki RATTOE There's a danger in showing graphics where anyone can post anything without accountability for their actions. A client that only shows tokens for a specific asset could do this📷1

RavencoinDev at 2:43 PM

True, unless you want to see the messages even if you haven't opened your wallet in a week.

Rikki RATTOE at 2:44 PM

the only thing I was thinking was if you simply linked the image, somebody could just copy the link and text it off to everyone and the coupon isn't all that exclusive

UserJonPizza|MinePool.com|Mom at 2:44 PM

Maybe a mobile link-up for a easy way to see messages by just importing pubkey(edited)

RavencoinDev at 2:45 PM

Speaking of mobileWe are also getting close to a release of mobile that includes the ability to show assets held, and transfer them.Roshii has been hard at work.📷6📷1

Vincent at 2:46 PM

can be hidden also?

Could we do zerofee mempool messaging that basically gets destroyed after it expires out of the mempool for real-time stealth mode messaging

corby at 2:48 PM

That's interesting!

RavencoinDev at 2:49 PM

There are other solutions available for stealth messaging, that's not what the devs had intended to build. It does sound cool though @Under

Under at 2:50 PM

📷 we’ll keep up the good work. Looking forward to the db upgrades. Will test this weekend

RavencoinDev at 2:50 PM

Thanks!That leaves us with 10 minutes for the Dev Kit!Corby has been working on expanding some of the awesome work that @Under has been doing.

corby at 2:52 PM

Yes -- all of the -addressindex rpc calls are being updated to work with assets

RavencoinDev at 2:52 PM

Hopefully we'll be able to post the source soon once the initial use cases are all working.

corby at 2:52 PM

so assets are being tied into transaction history, utxos, etc

RavencoinDev at 2:52 PM

The devs want to provide a set of API's that make it easy for web developers to build solutions on top of Ravencoin.VinX is investigating the possibility of using Ravencoin to power their solution.

corby at 2:53 PM

will be exposed via insight-api which we've forked from @Under

[Master] Roshii at 2:53 PM

Something worth bringing up is that you will be able to get specific asset daba from full nodes with specific message protocols.

corby at 2:54 PM

also working on js lib for client side construction of asset transactions

[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 these threads 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:
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:
C:\Users\UserName\Desktop\quark-v2_w64\minerd64_sse4.exe
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:
C:\Users\Nexic\Desktop\quark-v2_w64\minerd64_sse4.exe -a quark -t 8 -o stratum+tcp://src.coinmine.pl:6020 -u Nexic.worker1 -p pass1
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.

Looks like I lost 1.54 BTC to a Core wallet mishap

Hey all,
So I was looking to cash out portion of my Bitcoin portfolio. Up until now, all I'd used was exchanges and the online Blockchain.info wallet. I was using Bitpay until now, however I was now on my Macbook and couldn't find a proper .dmg file for the Bitpay client. I then downloaded the Bitcoin Core wallet, one of the 5 I believe payment protocol enabled wallets listed on Bitpay (keep in mind I know nothing about the Core wallet other than that it holds a private key that I should back up). After downloading it, I generated an address and sent my Bitcoin to it. I made sure to double check the address multiple times. I then waited for confirmations - only to realize the Core wallet needs days to sync up with the blockchain and I wouldn't be able to use my Bitcoin until it does - quite unfortunate. I then waited. I didn't back up my private key right there and then because I didn't really see any need to. After it downloaded 50% of the blockchain, I realized my Macbook didn't have enough space. This is where it seems to have all gone to shit.
I had no space left on my Macbook so I deleted the contents of the 'blocks' folder. It was just a bunch of 'block' and 'rev' files numbered off. I then restarted the Bitcoin-Qt wallet and it allowed me to redirect the download to an external drive that I had inserted. Right here, my Bitcoin address disappeared from the 'Requested Payments History' tab. I tried to use the dumppprivkey command but the console just didn't recognize the public key.
I'm pretty much making this post as a last resort after talking to some friends as well. Anyone know if I made some dumb mistake and there actually is a way to get my Bitcoin back?
Here's the address to anyone that may think I'm trolling:

Have I missed any steps trying to recover an old wallet?

I found an old wallet.dat from 2012 on one of my hard drives with bitcoin qt 0.7.0. I made a backup of the wallet.dat to my current computer.
I downloaded the newest version of Bitcoin Core and let it sync the entire blockchain. When it was done, I closed Core, deleted the wallet file that it put in the folder, and replaced it with my backup. I reopened Core with the -rescan and -upgradewallet parameters. It said 0 bitcoins.
I checked the receive address on blockchain.info and that said 0 too. I went back to the old hard drive and opened bitcoin qt 0.7.0 and it said 0. I copied that receive address into blockchain.info and it said 0.
The thing I'm wondering about is the receive address in 0.7.0 was different than the one in Bitcoin Core after I restored the old wallet.. is that normal?
Anyway, not sure if I actually had any bitcoins to begin with, but wanted to make sure I did everything I could to double-check?

How to activate USAF

Hello, how can one activate user-activated soft fork? The "tutorial" on usaf.co is useless since my Bitcoin-QT client automatically starts when I start a computer. I have it installed on the external hard drive. That's probably a reason, why there's no Bitcoin folder in appdata, and therefore I can't create bitcoin.config file (I don't think Bitcoin-QT client could read it). So is there any other way to activate it without reinstallation of the client? And if I have to reinstall the client, how can I tell it, that I want all the blockchain data on the different hard drive? Also, is there any way to ensure, that my node is really signaling for UASF?
Thanks.

[Bounties] Bug hunters wanted

Testnet.BitcoinReserve.ch is looking for a few good bug hunters.
Offering $75 in BTC for fatal bugs and a sliding scale all the way down to $2 for minor typos. The first round of testing (see /BitcoinReserve) paid out over $350 to various testers.
Bitcoin Reserve allows deposit and withdrawal of Bitcoin, conversion to/from dollars and payments to other members in USD or BTC. The system is currently running on Testnet3.
I am the final and only arbiter of bounty payouts. The first person to find and report a particular bug will be paid a bounty. Subsequent reports on the same issue are helpful but will be paid a partial bounty only if they add worthwhile information. Be sure to include the URL and any supporting information with your bug reports: Bugs must be reproducible or otherwise independently observable (i.e. reviewing server logs). Larger bounties will be paid to the address you send me through a reddit personal message, smaller bounties will be paid through changetip. If bounty payouts end up exceeding 3 BTC, the contest will be paused as we examine what the hell is going on.
Again, the website is https://testnet.bitcoinreserve.ch, Happy Hunting!

Any way to recover wallet access? Reward if you help me recover

Hi all, I'm looking for some insight on whether my wallet is gone or not.
Here's the backstory. I tried to transfer my btc to cold storage in 2015 (and thought I did) but when I tried to open that wallet, it was empty. For some reason, the transaction never went through. I went back to my old SSD, but I had deleted a lot of stuff off of it, including the wallet file (dumb, I know :/). Here was my setup:
I had bitcoin qt installed on my external harddrive. I didn't realize it was storing the wallet file and blockchain on my internal SSD which is how I accidently deleted it. When I opened the app again, it started downloading the blockchain again and it created a new wallet file on the SSD. I sent the SSD to a data recovery specialist, but they could not help.
There are some files on the external HD, but I don't know if they are useful at all. There's an src folder with a lot of H and CPP files, and a few other odds and ends. There's also a daemon folder with a bitcoind application.
Not sure what else I could do. Anyone have any thoughts on this? I'll reward anyone who can help me with a successful recovery. Thank you.
