Bitcoin Newcomers FAQ - Please read!

Welcome to the /Bitcoin Sticky FAQ

You've probably been hearing a lot about Bitcoin recently and are wondering what's the big deal? Most of your questions should be answered by the resources below but if you have additional questions feel free to ask them in the comments.
It all started with the release of the release of Satoshi Nakamoto's whitepaper however that will probably go over the head of most readers so we recommend the following videos for a good starting point for understanding how bitcoin works and a little about its long term potential:
Some other great resources include Lopp.net, the Princeton crypto series and James D'Angelo's Bitcoin 101 Blackboard series.
Some excellent writing on Bitcoin's value proposition and future can be found at the Satoshi Nakamoto Institute.
Some Bitcoin statistics can be found here and here. Developer resources can be found here. Peer-reviewed research papers can be found here.
Potential upcoming protocol improvements and scaling resources here and here.
The number of times Bitcoin was declared dead by the media can be found here (LOL!)

Key properties of Bitcoin

Where can I buy bitcoins?

Bitcoin.org and BuyBitcoinWorldwide.com are helpful sites for beginners. You can buy or sell any amount of bitcoin (even just a few dollars worth) and there are several easy methods to purchase bitcoin with cash, credit card or bank transfer. Some of the more popular resources are below, also check out the bitcoinity exchange resources for a larger list of options for purchases.
Here is a listing of local ATMs. If you would like your paycheck automatically converted to bitcoin use Bitwage.
Note: Bitcoins are valued at whatever market price people are willing to pay for them in balancing act of supply vs demand. Unlike traditional markets, bitcoin markets operate 24 hours per day, 365 days per year. Preev is a useful site that that shows how much various denominations of bitcoin are worth in different currencies. Alternatively you can just Google "1 bitcoin in (your local currency)".

Securing your bitcoins

With bitcoin you can "Be your own bank" and personally secure your bitcoins OR you can use third party companies aka "Bitcoin banks" which will hold the bitcoins for you.
Note: For increased security, use Two Factor Authentication (2FA) everywhere it is offered, including email!
2FA requires a second confirmation code to access your account making it much harder for thieves to gain access. Google Authenticator and Authy are the two most popular 2FA services, download links are below. Make sure you create backups of your 2FA codes.
Google Auth Authy OTP Auth
Android Android N/A
iOS iOS iOS

Watch out for scams

As mentioned above, Bitcoin is decentralized, which by definition means there is no official website or Twitter handle or spokesperson or CEO. However, all money attracts thieves. This combination unfortunately results in scammers running official sounding names or pretending to be an authority on YouTube or social media. Many scammers throughout the years have claimed to be the inventor of Bitcoin. Websites like bitcoin(dot)com and the btc subreddit are active scams. Almost all altcoins (shitcoins) are marketed heavily with big promises but are really just designed to separate you from your bitcoin. So be careful: any resource, including all linked in this document, may in the future turn evil. Don't trust, verify. Also as they say in our community "Not your keys, not your coins".

Where can I spend bitcoins?

Check out spendabit or bitcoin directory for millions of merchant options. Also you can spend bitcoin anywhere visa is accepted with bitcoin debit cards such as the CashApp card. Some other useful site are listed below.

Can I mine bitcoin?

Mining bitcoins can be a fun learning experience, but be aware that you will most likely operate at a loss. Newcomers are often advised to stay away from mining unless they are only interested in it as a hobby similar to folding at home. If you want to learn more about mining you can read more here. Still have mining questions? The crew at /BitcoinMining would be happy to help you out.
If you want to contribute to the bitcoin network by hosting the blockchain and propagating transactions you can run a full node using this setup guide. If you would prefer to keep it simple there are several good options. You can view the global node distribution here.

Bitcoin Units

One Bitcoin is quite large (hundreds of £/$/€) so people often deal in smaller units. The most common subunits are listed below:
Unit Symbol Value Info
bitcoin BTC 1 bitcoin one bitcoin is equal to 100 million satoshis
millibitcoin mBTC 1,000 per bitcoin used as default unit in recent Electrum wallet releases
bit bit 1,000,000 per bitcoin colloquial "slang" term for microbitcoin (μBTC)
satoshi sat 100,000,000 per bitcoin smallest unit in bitcoin, named after the inventor
For example, assuming an arbitrary exchange rate of $10000 for one Bitcoin, a $10 meal would equal:

Safe methods for Consolidating BTC dust?

I've received some dust transactions this past year and read up on the phenomenon here and here and here.
What's the smart thing to do about it?
I'd really like to just group them all up and send them to my RaspiBlitz Lightning node to play with the network there, but is this dangerous?
As far as I've been able to tell the danger would come from grouping a bunch of these small transactions together as it could tie the addresses together as well as reveal the involved public keys, but so what?
Am I just misunderstanding the dangers here?

How can you use your full node as trusted node for BLW ?

I recently decided to use Bitcoin Lightning Wallet (BLW) as my mobile lightning wallet. I have a RaspiBolt running as full Bitcoin and Lightning node and I would like to use my full node as trusted node for the BLW's SPV.
When I set it up in the app, "Connecting to peers" is flickering and the Bitcoin wallet doesn't seems to synchronize. I bet I have to allow the SPV on my full node. Does someone know how to do it ?

Thanks !

Why use your own full node? Answered by Pieter Wuille

One of Bitcoin's strengths - the most important in my opinion even - is the low degree of trust you need in others.
If you use a full node for your incoming transactions, you know that there was no cheating anytime in the history of your coins:
... with one exception: because there is a need to pick a winner in presence of multiple competing valid versions of the ledger, (a majority of) miners have the authority to pick the version of the block chain that wins. This means their power is limited to choosing the order in which otherwise valid transactions occur, up to and including the right to delay them indefinitely. But they cannot make invalid transaction look valid to a full node.
If you are not running a full node, the amount of trust you're placing in others increases.
SPV nodes (such as some mobile clients, and Multibit) place a blind trust in the majority of miners, without checking validity of the blockchain they produce. It still requires a majority of miners to mislead an SPV node, but they can make it believe anything (including "You received 10000000 BTC!"). The reason why this does not happen is because full nodes would not accept such blocks, and assuming a large portion of the ecosystem does rely on full nodes, miners who do this would not see their blocks accepted by the larger economy, resulting in them wasting money.
Centralized services (most webwallets) make the user trust whatever the site says. They can claim anything.
So I hope you now see the importance of full nodes in this model. If you run a full node somewhere on the network, and nobody looks at the transactions it validates, it is indeed contributing to the network, but it is not helping with the reduction of trust.
Look at it another way: if only a few large players in the Bitcoin ecosystem were running full nodes, it only requires a malicious intent, or an attack/threat against them, to change the system's rules, as nobody else is validating.
Doing transactions in the Bitcoin ecosystem helps the Bitcoin currency. Running a full node helps the network. Using a full node helps you and the ecosystem reduce the need for trust.
https://www.reddit.com/BitcoinBeginners/comments/3eq3y7/full_node_question/ctk4lnd/
Adding to that answer myself:
Running (and using) your own full node gives you the benefit of increased privacy, because you don't leak information about your UTXOs to the default node of your wallet, which can link your UTXOs together, perhaps even link them to your real world identity.
There are different ways how to set up a node (from simply installing the Bitcoin Core software on your computer to getting a plug'n'play solution such as Casa or Nodl), but to connect a (hardware) wallet to it is a little more tricky for now.
One of the projects I frequently recommend myself is https://stadicus.github.io/RaspiBolt/. It's somewhat cheap (~$150 for hardware, as compared to other plug'n'play nodes which are around $300) but can run 24/7 and includes guides how to set up Tor on the device, and how to use your hardware wallet with the node.

Brief introduction to Joinmarket (coinjoin implementation), incl setup guides for RaspiBolt and RaspiBlitz nodes

To understand the purpose and functionality of Joinmarket, you should first understand the basics of the CoinJoin mechanism. Some basic level introduction to CoinJoin can be found here:
https://bitcoinmagazine.com/articles/coinjoin-combining-bitcoin-transactions-to-obfuscate-trails-and-increase-privacy-1465235087 (includes a brief description of Joinmarket as well)
https://en.bitcoin.it/wiki/CoinJoin
What is Joinmarket?
Joinmarket is essentially a wallet with a very specific purpose: it enables users to do automated coinjoins (mixing of UTXOs) with each other. The user can assume the role of a Maker, offering their coins as being available for coinjoins, thus providing liquidity and earning small fees if their coins are being chosen for a mixing round. Or the user can assume the role of a Taker, choosing from the pool of available coins to initiate a mixing round.
Of course, the roles are not permanently fixed and the user can switch between them at any time desired. The coins never leave the user’s wallet and can be transferred out at any given point in time, so the wallet is non-custodial and trustless. Joinmarket requires the user to use their own node for that purpose.
So besides the basic wallet functionality, Joinmarket serves as a platform to match coinjoin Makers and Takers. Both profit in increased privacy for their coins, and Makers additionally profit from the small fees the Takers pay. The matching and mixing processes happen automatically, users only need to adjust some few settings (or simply use the default ones), fund their wallet and run the software.
For the role of a Maker the user runs the “Yield Generator” (automated script creating an offer), and for the role of a Taker there are two options of either sending a single coinjoined payment or to run the “Tumbler” for multiple coinjoins. Again, all these are automated functions, only requiring the funding of the wallet and starting the software with some few parameters.
Although Joinmarket has been available for almost four years and has a dedicated user base (and a stable liquidity pool), there is quite a hurdle for the set up as it requires working with command line interface. But it can be done by simply copypasting commands from the various guides. There is also a basic GUI (graphic user interface) available after the set up process.

[Note: if you only want to use Joinmarket as a Taker (using the Tumbler or the Sendpayment options) you don’t necessarily need the guides for RaspiBolt/RaspiBlitz. You can simply install Joinmarket on your desktop and let it connect to your node (you only need to adjust the joinmarket.cfg file, and possibly your bitcoin.conf file on your node, so Joinmarket can connect to it). You will need a running node in any case though (it can be a pruned node).
The reason why you would want to install Joinmarket on a Raspibolt/Raspiblitz itself is that when using the Maker feature (Yield Generator), it should be running continuously so Takers can take up your offer at any time they wish.]

List of plug'n'play full nodes (Bitcoin + Lightning) on a dedicated hardware

Here is a reference list of all plug'n'play Bitcoin full nodes known to me, most of them include Lightning functionality as well. Please note that those are for a very specific usecase: namely, for people who want a node on a dedicated device (running 24/7, not interfering with work on their pc/laptop) AND don't want to (or cannot) build their own dedicated node, or just want to have customer support in case things go wrong in the set-up process.
If you just want to run a node on your pc/laptop, it's as easy as downloading the Bitcoin Core software here and let it sync (which takes a while). If you want to build a dedicated device on your own (it's not as hard as you might think!), you can have it much cheaper than in the list below (for $100-150) and there are a number of excellent guides available, too. Most prominent ones are Beginner’s Guide to ️⚡Lightning️⚡ on a Raspberry Pi and RaspiBlitz. If you are more interested in Lightning Network, also check out Pierre's Node Launcher (for Mac and Windows).
So if you are still interested in spending money on a node and saving you the efforts of setting up everything by yourself, here are the options available to you (I'm not affiliated with either of those):
By Lightning In A Box (homepage, Twitter):
They have three main models available:
By Bitseed (homepage, Twitter):
By Nodl (homepage, Twitter):

Raspiblitz with Bitcoin Core 0.16.3

Raspiblitz with Bitcoin Core 0.16.3
My full node and lightning wallet is finally functional. Thanks for the guidance of @Stadicus3000 and @rootzoll.
These are the tutorials I used:
https://github.com/Stadicus/guides/tree/masteraspibolt
https://github.com/rootzoll/raspiblitz/blob/masteREADME.md
Needed to change the RaspiBlitz script to install the Bitcoin Core 0.16.3 instead of the now unavailable 17.0-RC3.
For the HDD I used this X820 expnsion board http://www.raspberrypiwiki.com/index.php/X820.
This way only one power source is needed and will be nice and compact once housed without the LCD on.

Why lightning? Answering all questions as I see it evolve.

I am aware of some limitations of lightning at the moment. If you run your own node majority of issues are easy to solve. Once bitcoin is global currency you don’t or rarely have to close channels. You can open direct channels with your family or friends which you use most common and for all your life making payments transfer easy. No other blockchain can scale as much as lightning if we are looking at global adoption it’s million tps. If you are talking about onboarding channels we all know we are still 10 or 15 years away from any crypto mass adoption so it’s plenty of time to onboard majority. By that time the hardware tech should have also evolved to an extent that you should be able to run full nodes on raspi 100 with 25-50 mb blocks.. costing still as of today.. that would be time to increase block size to 25-50 mb range ...boosting further onvoarding...static lnd channel back up is here with lnd 0.6 so recovering lost funds has gotten a lot easier. From here on lightning is only going to advance further not backwards if you understand any budding technology. I am running a full lightning node for last 4 months on raspi can access anywhere from world without any flaw doing micro transactions between WOS and my node wallet with my mobile. It is flawless. Using hubs third party if you can’t be online 24x7 is again optional but I foresee lnd nodes built in your routers modems or TVs in future running in background solving this further. Third party trust, hubs is again optional if you run your node. Routing is not a problem if you connect to good one or two nodes at the moment. If they go offline close your channels find other ones. Same can’t hold true if your money gets stuck in a bank account. As lightning is growing it’s becoming a no issue. It would be very exciting to see coming 5 years to see this tech grow from a baby to a full blown adult.
Finally, I would say why such a complicated appearing solution or tech when we have simpler more scalable appearing solutions already available? The simple answer to this is when technology entangles with economics and censorship resistance there is never going to be a better answer than bitcoin due to its time tested tech, monetary policy, incentives and most important the community.
Also, imagine if 1 btc goes 1 or 5 mill today’s lightning transaction would go 1000% times in terms of dollar so do not need much for day today transaction even today with current state of lightning .

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)

Explain Channels and Capacity to Me

I've been playing around with the Lightning Network using a few Android apps (eclair, lightning-wallet, and Bluewallet). I also have my own Lightning Node running on a Raspberry Pi (thanks to u/Stadicus). I've been enjoying sending Satoshis to myself and getting a feel for how this technology works.

BUT, I cannot wrap my head around understanding node Capacity, channel capacity, and how much Bitcoin I can send/receive from the Android Apps or from my Node. For instance, with the Lightning-Wallet app, I had to spend some Satoshis before I had enough room to receive any back. With my own raspi node (set on autoconnect) I seem to be able to receive Satoshis without having to spend any first. How does this work?

I feel really dumb even having to ask this question, but I'm hoping someone can explain this in a simple way. I'm sure I'm not the only one who is confused by this.

WIP: Blackpi - a stake device based on raspberry

Warning: This is a WiP and it's using Blackcoin Lore which is still in beta. Please be aware of that and backup your wallet.dat before you put any real values in this!
UPDATES
29.12.2017
22.06.2017
I am currently trying to set up blackoin on raspberry. Community members asked for a tutorial to compile it, so I will start with this here. Maybe in the future it would even be possible to turn it into a headless (=without screen and keyboard) image to put on an SD card and just boot up the wallet.
I used the latest Blackcoin Lore by janko33 for this process, however it should be quite the same with the "original" core wallet by rat4/johndolittle. Blackcoin Lore is not deemed as stable as it is still in beta, so it's up to you what source tree you take.
Please be also aware, that compiling on a small computer like raspi can take a while. Please also note that Lore is still in beta. The names in the archive are still "bitcoin". There is an update comming where the naming is correct and also maybe a few bugfixes.
** Tutorial: **
You first need to get raspbian. The lite image will work, it's a small version of the operating system without a graphical interface, so you will need ssh to operate it. The image is 294 MB but you will want to have a bigger card. 2GB is certainly too small, better get 16 or even 32GB - you also will need space for the blockchain!
To install it I followed this guide
https://hackernoon.com/raspberry-pi-headless-install-462ccabd75d0
Get the raspdian image file from:
https://www.raspberrypi.org/downloads/raspbian/
Also get Etcher from
https://etcher.io/
Etcher is a tool to write img files to an SD card/USB-stick.
After writing, open the card in your explorer and add a file "ssh". The file sould be empty and just be called "ssh" (not ssh.txt or something). It will tell raspi to activate ssh on boot.
Then boot up your raspi with the card and plug it into your network. Consult your router's LAN-page to find the device, it should register to your router as "raspberry" or so. Open up Putty and login to your raspi using pi as username and raspberry as password.
After login you can configure your raspi, please read the guide linked above for more details.
Note: One important thing that you should configure is your timezone! Use
sudo raspi-config 
Go to 4. Localisation Options and set the time to your timezone. If your time is way off, you would get troubles with staking, so make sure you always have the time set right!
After you got everything set up, get the build environment ready:
sudo apt-get install build-essential libtool autotools-dev automake pkg-config libssl-dev libevent-dev bsdmainutils #Installs alot and can take a while git clone -b Blackcoin-Lore https://github.com/janko33bd/bitcoin Blackcoin-Lore cd Blackcoin-Lore cd depends make -j 6 HOST=arm-linux-gnueabihf cd .. ./autogen.sh ./configure --prefix=`pwd`/depends/arm-linux-gnueabihf 
# note: ` = is a "backtick" not an apostroph. It causes the outpupt of "pwd" being inserted there
make -j 6 # -j n tells the compiler to use more cores, speeds that up a little (n = 1.5*cores installed) sudo make install 
This should compile so far. Update: Lore does not need Berkeley DB 4.8 to be installed, so just go with the DB provided by the repository works (libdb++-dev). (Thanks patcrypt)
After compile you can run the wallet with
lored 
And after it synced you have bitcoin-cli to control the wallet.
Issue: Synching blocks takes an awfully long time on raspi for some reason, even with Lore (that syncs blocks in a few hours instead of a whole day on a normal computer). If anyone knows how to speed up that process, please let us know!
This thread is a WiP. Please post all issues and errors here, I will then edit the OP to make it into a real, working tutorial.
On a note it was mentioned, that using an USB-stick here instead of a card would make sense since the cards are more prone to failure than USB-sticks. I will include setting it up on USB in a later version of this tutorial.
Some tips and tricks
Since compiling takes a longer time, it is recommented to run it in the console in a screen. Screen is a terminal tool that supports multiple windows in the same shell and, most important, detaches when your ssh connection breaks. Using screen you can simply reconnect and use screen -r to attach to your running shell again. To use screen, you need to install and then start it before you start the whole build process within a screen-shell.
sudo apt-get install screen screen #Start install/build process here #Type [ctrl-a] [d] to detach from the screen and put it in the background #After reconnect type screen -r to jump back into your running shell 
If you want to see your blocks being processed while the wallet syncs to the network, use the following command on a second shell (new Putty instance or screen window which you can open in screen with [ctrl-a] [c] (hit [ctrl-a] [n] to cycle through the windows in screen)
watch -n 5 lore-cli getinfo #This will execute the command "bitcoin-cli getinfo" every 5 seconds and thus display live update of your wallet info 
How to use that thing?
Here are a few helpful CLI commands, call them with lore-cli
help - Returns available commands help  - Returns detailed help to a  getinfo - Returns a descriptive information of your wallet, including balance getwalletinfo - Returns short information about your wallet, including balance, unconfirmed balance, immature balance, number of tx ect getaccountaddress 'raspi' - Returns an address for your wallet. If the account does not need to exist, it will be created with new address sendtoaddress   - Sends  to  sendtoaddress   substractfeefromaccount - Sends  minus tx fee to  getnewaddress  - Returns a new address for  each time you call the command.  is optional 
Further plans for this tutorial/project
Have fun!

My RaspiBlitz install stopped working, is now giving me grief - details below

A few weeks ago, just as Xmas madness was in full swing, my RasPi lightning setup (from these directions: https://github.com/rootzoll/raspiblitz) took a shit.
An error message was printing on the screen suggesting data corruption (sorry, don't recall exact message, but when I looked it up online, suggestions were to run fsck.
I took my drive, plugged it into my Ubuntu laptop, and ran fsck. It ran, I plugged the drive back in to the RaspPi and started it up.
So it needs to synch, no problem. I wait a few days but same message... something is wrong. Also it now wants me to re-input my wallet unlock password every time I try to do anything...
I was running version 0.93 so I ran the XXupdateScripts.sh thinking that might help...
Now I get the error on reboot of:
Starting the main menu ... ls: cannot access '/home/admin/raspiblitz.info': No such file or directory
WARNING: NO raspiblitz.info FOUND -> bootstrap not running?
So I can no longer get past the most basic startup...
I don't want to touch anything else since it appears I am breaking things... any ideas how to get moving again?
If I need to do a nuke/reinstall - is there a guide for recovering my bitcoin that I had in the wallet? Yes I have my cypher seed.

locked 20eur in raspibolt - please help me recover it

I sent 20eur in btc to the raspibolt to 3QpZhtkuW23pQ4iCNjhU9St4krcyKpaCTC.
After opening a connection and then a channel, the raspi showed zero btc everywhere - I didn't wait long enough I guess now. But then, I panicked, misconfigured the raspi and while bugfixing my own faults on it, I had the "brilliant" idea of recovering the bitcoins somewhere else using the 24 seed words of the wallet.
Here comes the challenge. Electrum and Armory were not able to import the private keys using my 24 word seed so that I can see what happened in this wallet and for example send the remaining bitcoins not locked in a channel to another wallet not on the raspi.
Anybody out there having an idea how I should do this?
