The RaspiBlitz is optimized for being setup during a workshop at a hackday or conference (see detailed workshop tutorial). When it comes fully assembled with an up-to-date synced blockchain, it's possible to have it ready in about 2 to 3 hours.
If you start at home ordering the parts from Amazon (see shopping list below) then it's a weekend project with a lot of downloading and syncing time where you can do other stuff while checking on the progress from time to time.
If you already run a Umbrel or myNode you have basically all the hardware needed and you can make the Migration to RaspiBlitz from Umbrel/myNode under one hour.
All parts together cost around 180-250 USD - based on shops and location.
If you like to support the RaspiBlitz project you can order a plug&play RaspiBlitz from raspiblitz.com
Find a list of other shops selling a plug&play RaspiBlitz in your area on raspiblitz.org.
The cheapest way is to buy and assemble the single parts yourself. There are two packages.
Please try to use the exact hardware models that are recommended in the shopping lists. We have had multiple reports where, for example, other SSD or SSD cases/controllers lead to problems. The idea of the shopping lists is to provide you the best tested hardware components that work together - improvement recommendations are always welcome.

Useful info:
- What's new in Version 1.7.1 of RaspiBlitz?
- How to update my RaspiBlitz?
- How to migrate to RaspiBlitz from Umbrel/myNode
- How to verify the SD card image after download?
You need to write the downloaded SD card image (the img.gz-file) to your SD card (16GB minimum) - you can use the very easy tool Balena Etcher for this: https://www.balena.io/etcher/. It's available for Win, Mac & Linux.
Insert the SD card and connect the power plug.
- Make sure to connect the raspberry with a LAN cable to the internet at this point.
- Make sure that your laptop and the raspberry are on the same local network.
Troubleshoot:
- I don't have a LAN port on my Laptop - how to connect to my RaspiBlitz?
- Is it possible to connect the Blitz over Wifi instead of using a LAN cable?
- Can I directly connect the RaspiBlitz with my laptop?
- I connected my HDD, but it still says 'Connect HDD' on the display?
When everything boots up correctly (one reboot is normal), you should finally see the local IP address of your RaspiBlitz on the LCD panel.
Now open up a terminal (OSX/Win10) and connect through SSH with the command displayed by the RaspiBlitz:
ssh admin@[YOURIP] → use password: raspiblitz
Now follow the dialogue in your terminal.
Further down you will find more detailed documentation of the setup process.
If you run into a problem or you have still a question, follow the steps below to get support. Also check the setup documentation for details.

The following documentation will provide more detailed background information on the setup process.
If you are looking for a tutorial on how to organize a workshop to build the RaspiBlitz, see here.
Every time you start with a fresh SD card image you will be offered different options.
For example this is also the point where you can import a Migration file from an older RaspiBlitz - read about Migration further down.
But because you are setting up a brand new RaspiBlitz you will choose here FRESHSETUP.
Then you will be asked what to do with the connected hard drive/SSD.
If there is already a blockchain on your hard drive/SSD you will be asked if you want to use this pre-synced/validated data or if its OK to delete it. If there is no blockchain data this question will be skipped.
Finally you have to agree that all (other) data on the hard drive/SSD will be deleted, except the blockchain if you selected that previously. This might take some seconds.
First thing to setup is giving your RaspiBlitz a name:
The name you choose for your RaspiBlitz will also be used as your public alias of your lightning node so choose wisely.
Then you can choose which Lightning implementation you want to run on top of your Bitcoin Fullnode.
RaspiBlitz started with LND from Lightning Labs which is used by most other RaspberryPi lightning nodes and works with most additional apps.
But you can now also choose CL for c-lightning by Blockstream which is a good choice for more experienced node operators & lightning developers that want to use the highly customizable plugin structure that c-lightning offers.
It's also possible to use both lightning node implementations in parallel on your RaspiBlitz later on - just pick one to start with for now.
Choose NONE if you're only interested in running a Bitcoin full node without Lightning.
In the following we show the setup with LND - which is very similar to the steps with c-lightning.
If you chose to use one of the lightning implementations you will now be asked if you want to start a NEW wallet/lightning node or if you have an OLD lightning wallet/node that you want to re-create.
Normally you just chose NEW here, but to recover an old wallet you have the following options if you choose OLD:
Choose this option if you have made a complete backup of the LND or c-lightning data and have a tar.gz file starting with the word 'lnd-rescue' or 'cl-rescue' available. It will recover all your on-chain funds and open channels you had. But you have to make sure that the rescue backup you have is really the latest version - otherwise you might lose channel funds.
If you have tar.gz file that starts with 'raspiblitz', that's a migration file. That also includes your old LND/c-lightning wallet, but you import that file at the beginning of the setup process with 'FROMBACKUP - Upload Migration Backup' instead choosing FRESHSETUP
The next best option is if you have the channel.backup file and the word list seed.
This allows you to recover all on-chain funds (i.e. "bitcoin balance") in the lightning wallet, and gives you a good chance of recovering the off-chain funds (i.e. "lightning balance") you had in open channels, as long as the remote peer supports option_data_loss_protect which is very common since 2020.
All channels you had open before will be closed during this procedure.
See Bitcoin Optech - Static Channel Backups for more background information on this process.
If you only have the seed word list (RaspiBlitz 1.1 and older) you can at least try to recover your on-chain funds. Recovery of channel funds is not very likely in this scenario.
But normally you are setting up a new node - so simply choose NEW in the menu.
Finally you have to set 3 passwords called A, B & C. For each password please choose unique, single strings, without spaces and special characters, that are at least 8 chars long.
You can use this RaspiBlitz Recovery Sheet (PDF) to write those passwords down for safe storage and also use it later on for your Seed Words.
The password A,B,C idea is based on the RaspiBolt Guide Preparations - check out for more background.
First, password A is requested - this is the password which will be used for SSH login and it's also set for the existing users: admin, root, bitcoin & pi.
The bitcoin and lightning services will later run in the background (as daemon) and use the separate user “bitcoin” for security reasons. This user does not have admin rights and cannot change the system configuration.
Then enter password B - this is internally used for the bitcoin RPC interface. It is also used as login for additional apps like the RTL-WebGUI or the Blockexplorer.
And finally enter password C - this is used to encrypt/lock the lightning wallet on the hard drive/SSD and is used by LND. Every time a lightning node is started/rebooted LND needs load the wallet into memory to work with and ask you for password C to "unlock" the wallet.
In the early RaspiBlitz versions there was also an additional password D, that is no longer in use.
After this the setup process will need some time to set everything up - just wait until it's finished. This can take from 10 to 30 minutes:
Once the basic setup has completed your lightning node will be setup & your lightning wallet will be created for you. As part of this process you will be presented with your lightning node "seed words" which you MUST write down on paper (or engrave into steel) and store in a secure location. You will need to confirm that you wrote the seed words down before you can continue.
WRITE YOUR SEED WORDS DOWN before you continue - you will need them to recover funds in case of failing hardware etc. If you just want to try/experiment with the RaspiBlitz, at least take a photo of the seed words with your smartphone, so you have something just in case. If you plan to keep your RaspiBlitz running store this word list offline or in a password safe.
You can use this RaspiBlitz Recovery Sheet (PDF) to write down your seed words for safe storage.
If you don't have a full copy of the blockchain pre-synced/validated on your hard drive/SSD then you will now be asked how you want to get your copy of the blockchain. There are two basic options :
For the new RaspberryPi 4 (with SSD & min 2GB RAM) this is the best way to go.
It will take around 3-6 days to sync & validate directly with the bitcoin network.
With this option, you have done it the original don't trust, verify way.
For the old RaspberryPi 3 this is not recommended. A RaspberryPi 3 has a very low power CPU and syncing+validating the blockchain directly with the peer2peer network can take multiple weeks - that's why for a RP3 you should choose the COPY option .
If you have a friend that is already running a synced RaspiBlitz or you have a laptop with enough free space on the hard drive that can download & validate the Blockchain much faster you can also choose the COPY option.
You can then delete existing blockchain your RaspiBlitz already started syncing for you
To copy from another RaspiBlitz choose BLITZ and follow the instructions.
Know that the other Blitz will be offline to the lightning network during the copy that will take multiple hours.
To copy from your laptop/computer (WINDOWS, MACOS & LINUX options) you first need to download & validate the blockchain on your own computer/laptop.
To do so, install latest bitcoin-core (0.18.1 or higher) from bitcoin.org and keep it running until the blockchain is synced (will need around 400 GB).
Then under the COPY option choose the Operating System.
The copy will be done over the local network by SCP (SSH file transfer) - follow the instructions given in the dialogues.
It's advised to keep a backup of Bitcoin Core & the blockchain data directory on your laptop/computer in case you need to re-setup the RaspiBlitz.
More details: I have the full blockchain on another computer. How do I copy it to the RaspiBlitz?
If you don't have the Bitcoin blockchain already on another laptop or RaspiBlitz simply choose SELFSYNC.
And hooray :D Your RaspiBlitz is ready to go! Welcome new node operator.
If you hit OK, the RaspiBlitz will go into a final reboot.
Just wait a bit and then the SSH command to login again. Logging in via SSH requires password A that you setup earlier.
If you run LND you will be asked to unlock your wallet - this requires password C.
There is an option to activate auto-unlock of LND if you prefer, this can be found under SETTINGS in the main menu.
Your RaspiBlitz might need quite some time to sync and validate the blockchain -- this can be multiple days. In the beginning you might see fast progress but this gets slower later on as historical blocks start to get fuller. Your RaspberryPi CPU will likely get quite hot during initial sync. However this is OK as the RaspberryPi has its own protection against overheating and will ensure the CPU doesn't critically overheat.
Once the Blockchain is synced you will enter the SSH Main Menu:
All options on the main menu will be explained below in the feature documentation.
OK .. so from here on out, your RaspiBlitz is ready to play with.
If you need an idea of what the most basic next steps to experience Lightning would be:
- Fund on-chain wallet
- Open a channel
- Make a payment
If you would prefer to do this from a web browser with a dashboard UI, instead of an SSH terminal, go to SERVICES, activate the RTL Webinterface, and after install you will find a new menu option for RTL in the SSH main menu - it will give you all the information so that you can now open the RTL web interface in your browser.
Have fun riding the lightning :D
*We always love seeing photos of new RaspBlitzes added to the network, tag @rootzoll in your pictures on twitter. There is also a RaspiBlitz Donation Page, why not try to send some satoshis there with your new RaspiBlitz :D *
These are the features available through the RaspiBlitz SSH menus. They have the goal to offer some basic/fallback functionality & configurations. More complex or user-friendly tasks are best to be done with wallets, apps and scripts you connect to your Lightning Node via APIs - because you have a full Bitcoin- and Lightning-Node on the RaspiBlitz.
So let's take a look at the SSH main menu in detail:
This is the screen that gets displayed on the LCD/display. It's useful to call in a remote situation from SSH if you don't have your RaspiBlitz next to you, or if you want to copy+paste your nodeID or make a screenshot.
It's not automatically updating. It's just for one-time info.
- Why is my bitcoin IP on the display red?
- Why is my node address on the display red?
- Why is my node address on the display yellow (not green)?
Under LND/c-lightning Wallet options you will find some basic tools for managing your Lightning node.
These are very simplified in the RaspiBlitz SSH menu for learning purposes.
For more advanced management of your Lightning node see additional apps under SERVICES.
Before you can open channels with other nodes you need to put some coins in your on-chain wallet (managed by your lightning software). Use this option to generate an address to send funds to.
Reminder: RaspiBlitz is still experimental software. With funding your lightning node you accept the risk of losing funds. So just play with small amounts - something in the area of 20 EUR/USD should be enough to make your first experiences. Also, it's a good privacy practice to coinjoin your coins before sending them to any Lightning Network wallet.
You can fund it multiple times - starting with small amounts first to test. Your lightning node will always generate a different address, but all funds you send will get into the same LND on-chain wallet.
Before you can open a channel with another node on the network, you need to connect this node as a peer to your node.
Opening a channel with a peer is just optional. Having another node as peer helps your node to receive information about the lightning network through the gossip protocol. It will help your node to find better routes through the network.
To open a payment channel with another node, you can use this option.
Find interesting nodes to open channels with through online directories like 1ML.com or join the RaspiBlitz NodeManager telegram group to meet people to open channels with: https://t.me/raspiblitz
Bear in mind that this option will open a public channel that can be seen by everyone in the network and chosen by them as part of their payment route.
This is good if you want to route payments.
If you do not want to route payments for others, you can use a so-called "private" (i.e. unannounced) channel which others cannot use as part of their payment route.
To do this you must go to the command line and open the channel with the -private option.
This is just a very basic shell script. For more usability, try the RTL Webinterface (under Services) or connect a (mobile) wallet with your RaspiBlitz.
Pay an invoice through lightning.

If you are looking for something to test payments with Lightning, why not donate some satoshis to RaspiBlitz development? Thanks :)
Create an invoice to send to someone for a service to be paid through lightning.
This is just a very basic shell script. For more usability try the RTL Webinterface (under Services) or connect a (mobile) wallet with your RaspiBlitz.
Here you can change the alias name of your node as it is shown as part of the Lightning network.
This option is only available if you have channels open.
With this feature you can close down all open channels and get the funds locked up in those channels returned to your on-chain wallet.
You may choose to force-close some channels where the channel partner is no longer reachable. Keep in mind that when you force-close a channel it can take a much longer time until your funds are available again through your on-chain wallet.
Use if you want to remove all funds from the RaspiBlitz.
Here you will find basic settings for your RaspiBlitz:
Activate/Deactivate settings with the space bar and then select 'OK' to activate changes. You can find more details about those options (top to down):
Your RaspiBlitz has an LCD that is touchscreen capable. You can switch on this new feature that is still in development.
It will enable 4 touch buttons on the left hand side of the screen.
- Info - to be defined later
- Node - shows the nodeID/uri as QR code (used to open channels from mobile wallets)
- Invoice - creates an Invoice-QR code that can be used for payments
- Off - Shutdown or Restart the RaspiBlitz
If you switch this on you can rotate the LCD of your RaspiBlitz 180 degrees. This might make sense if you have a special case or wall mount.
You can run both your Bitcoin & Lightning nodes, as well as additional apps, behind a Tor hidden service.
This replaces your clearnet IP address with an .onion style hidden service address.
Running your node as a hidden service has some benefits:
- You don't publish your IP address so it's much harder to resolve your real name and location.
- You tunnel through the NAT of your router and make your Bitcoin and Lightning nodes reachable (i.e. allow incoming connections) from all other Tor nodes on the network(s).
- By using a Tor address it's possible to move the node to a different IPv4 address and keep the existing (i.e. previously opened and funded) channels functional.
But this can also come with the following side effects:
- Some Mobile wallets don't support connecting to RaspiBlitz over Tor yet.
- Lightning nodes that don't run Tor cannot reach you (like behind NAT).
Using Tor hides your IP address but will possibly increase the time it will take for your node to route a payment. Setting up over clearnet will give you a lower response time when routing payments but your IP address will be freely available to the rest of the network like the node tippin.me. If you need to be private and/or don't want to doxx your home network then Tor might be the option for you. However if privacy isn't something you need and/or want, or you are trying to set up a service that your node is the back end for, then clearnet might be more advantageous choice.
To try it out, just switch on the service - you can deactivate it later on if it's not working for you.
It is very convenient to learn and test to play around in a "sandbox" environment. RaspiBlitz allows this through activating "testnet & signet" that run in parallel to the "mainnet".
Once activated you will see an additional option in the SSH Main Menu that will give you more options to operate the Testnet & Signet.
To get some bitcoin testnet coins, you can use "faucets" from different places on the internet, here are a few links:
- https://coinfaucet.eu/en/btc-testnet/
- https://testnet-faucet.mempool.co/
- https://kuttler.eu/en/bitcoin/btc/faucet/
- https://faucet.lightning.community/
You can read more about TESTNET and Bitcoin faucets here: https://kuttler.eu/code/bitcoin-testnet-blockchain-size-in-2020/
With ZeroTier you can add your RaspiBlitz to a software defined network - see for details: https://en.wikipedia.org/wiki/ZeroTier
This needs to be switched on to see the sub-settings options for LND.
If switched on it means the LND lightning node implementation is installed and running on your RaspiBlitz - it can run in parallel to c-lightning.
If activated you will find an additional option in the SSH Main Menu that offers you more options for operating the LND node.
Also under SERVICES some apps might only be available if LND is activated.
The channel autopilot feature of LND allows an "autopilot" to automatically use around half of your on-chain (i.e. bitcoin) funds, if available, to open new channels with other lightning nodes. The autopilot can be very useful to get started transacting swiftly if you're a newbie, as channels are opened for you. It is very likely that after a while, once you will have a hang of the concept of channels and how they work, that you will not need channels autopilot any more.
Beware that currently, toggling the Channels Autopilot setting will trigger a reboot of your RaspiBlitz. It is not a problem per se, just a bit of waste of time Improvement request #1953
Keysend is a feature of LND that allows your node to accept payments without having created an invoice first. This needs to be activated, for example, if you want to use your nodes for experimental messaging over the Lightning Network (see RaspiBlitz MOBILE apps like SendMany).
Not all peers in the Lightning network are necessarily friendly. Circuitbreaker is a background service you can activate that acts similarly to a firewall to protect your node. For details see: https://github.com/lightningequipment/circuitbreaker/blob/master/README.md
The RaspiBlitz will automatically unlock the LND wallet upon every start.
This feature is based on https://github.com/Stadicus/guides/blob/master/raspibolt/raspibolt_6A_auto-unlock.md
It can be activated under "Services" -> "Auto-unlock LND". We recommend that it be turned on when DynamicDNS is used. If there is a public IP change on your router LND restarts automatically, and without Auto-Unlock it will stay inactive/unreachable until you manually unlock it which could be annoying.
See below on this README for your Backup options when it comes to securing your funds against accidental loss. Storing the encrypted Static Channel Backup file to your Nextcloud account is an easy and secure way to do this.
Nextcloud is an open-source project to host your own files: https://en.wikipedia.org/wiki/Nextcloud - in its basics its an open DropBox replacement ... but can do much much more. You can run it yourself or use a hosted Nextcloud server. Find free Nextcloud providers here to sign up: https://nextcloud.com/signup/
You can connect a small extra USB drive to your RaspiBlitz (choose a small one up to 32GB, don't use second HDD or SSD here as that would drain too much power from the RaspiBlitz). That USB drive will then be used to store your latest StaticChannelBackup, just in case your HDD encounters an error.
An option for more advanced users -- that you only can set directly in the raspiblitz.conf -- is the automated backup of the StaticChannelBackup to another server by SSH/SCP.
For this you need to set the value:
scpBackupTarget='[USER]@[SERVER]:[DIRPATH-WITHOUT-ENDING-/]'
and you can optionally set custom options for the SCP command (for example to set a non-default port) with:
scpBackupOptions='[YOUR-CUSTOM-OPTIONS]'
On the target server add the root ssh public key of your RaspiBlitz to the authorized_keys file for the user - how to do this see: https://www.linode.com/docs/security/authentication/use-public-key-authentication-with-ssh/
This needs to be switched on to see the sub-settings options for c-lightning.
If switched on it means the c-lighting node implementation is installed and running on your RaspiBlitz - it can run in parallel to LND.
If activated you will find an additional option in the SSH main menu that offers you more options to operate the c-lightning node.
Also under SERVICES some apps might only be available if c-lightning is activated.
For more details on this lightning node implementation go to the c-lightning FAQ page.
CLBOSS is an automated manager for C-Lightning routing payments nodes. CLBOSS is effectively a bunch of heuristics modules wired together to a regular clock to continuously monitor your node.
Find more info at the CLBOSS GitHub.
You can protect your c-lightning wallet by encrypting it with your password C. On every system restart you will need to decrypt/unlock with that password before c-lightning can use the wallet. This adds some physical security for example in case your node get stolen.
The RaspiBlitz offers further Services, Apps and configuration (scroll down to see all options in the RaspiBlitz) also some Apps & Services might just be available if you installed/activated LND or c-lightning:
Activate/Deactivate service selection with the space bar and then select 'OK' to trigger Install/Uninstall. You can find more details about those options below (top to bottom):
Enables a user to run their own Electrum server on the RaspiBlitz. The server indexes the entire Bitcoin blockchain from the copy saved locally on your HDD/SSD, and the resulting index enables fast queries for any given user wallet. This allows the user to keep real-time track of their balance and transaction history using any wallet which speaks the Electrum Protocol, for example the Electrum wallet.
Since Electrum Rust server runs on the user's own machine there is no need for the wallet to communicate with external Electrum servers, thus preserving the privacy of addresses and balances.
By contrast, if you use your Trezor Hardware Wallet with the trezor.io web-wallet, it will tell their third party server your public keys - connecting them with your IP. Now you can use your Trezor with the Electrum Wallet by talking to your own Electrum Server, preserving your privacy.

JoinMarket is software to create a special kind of bitcoin transaction called a CoinJoin transaction. Its aim is to improve the confidentiality and privacy of bitcoin transactions.
--watch--> https://www.youtube.com/watch?v=uGHRjilMhwY
A CoinJoin transaction requires other people to take part. The right resources (coins) have to be in the right place, at the right time, in the right quantity. This isn't a software or tech problem, it's an economic problem. JoinMarket works by creating a new kind of market that would allocate these resources in the best way.
For more details see here.
After install, you will see a new JMARKET option in the SSH main menu - it will give you all the information you need to start using it.

https://github.com/fiatjaf/sparko#the-sparko-plugin
WalletUI for c-lightning with BOLT12 offers
https://github.com/shesek/spark-wallet#progressive-web-app
Different options to monitor & edit system services.
This feature should support connecting your RaspiBlitz to a mobile wallets or other apps.
At the moment the following mobile wallets are supported - some are only available if LND or c-lightning is activated:
- Zeus (iOS/Android) (LND & c-lightning)
- Fully Noded (iOS over Tor)
- SendMany (Android) (only LND)
- Sphinx Chat App (iOS/Android) (only LND)
Mobile wallets work as a remote control app for your RaspiBlitz.
First you need to install the apps on your phone - a QR code with the links to the app stores are displayed.
Then you need to pair them with your RaspiBlitz - also via a QR code displayed on the LCD.
If you run your RaspiBlitz without an LCD, there is the fallback option to display that QR code on the terminal as ASCII code (which might involve lowering your terminal's font size).
Information how to connect to Electrum Rust Server (if installed).
To connect the payment processing BTCPay server to your Lightning node you find here the needed Connection string.
If apps need access to the Bitcoin RPC service you can find this here.
Here you can activate a hidden service for your bitcoin node so that it can be used for the decentralized exchange called BISQ.
If you want to access your LND APIs (to connect apps and additional services) you need credential files that grant access (Macaroons & the TLS cert).
Macaroons: Access Tokens that allow certain command executions on the LND node. TLS: Certificate to secure/encrypt communication with the LND node.
In this menu, you can reset, re-sync, or export them as a file or string so that you can import them to apps and additional services.
Here are the following export options to get the Macaroon and TLS files to be used in other apps and wallets:
SCP is a SSH-like command used to transfer files. If we're able to SSH into the RaspiBlitz then using SCP to transfer files should also work. If you choose this option, RaspiBlitz will print prepared SCP commands you can copy+paste to run in a second terminal.
This method is recommended to export to:
Opens an ad-hoc web server so that you can download the files in your local network through the browser.
This is the least secure way to transfer those files - everybody in your local network has access to those file during download. Remember with the Admin-Macaroon somebody could take over your node and spend all your funds. Just use as last fallback.
####### Hex-String
The Macaroons and TLS.cert files can be copy+pasted as Hex-Strings from RaspiBlitz to any other app that supports that format. If you choose this option, RaspiBlitz will print all the files for you as Hex-String to do so.
This method is recommended to export to:
The RaspiBlitz offers now also Subscriptions. These might be free or paid third-party services.
Under LIST my Subscriptions you will always find the list of all your active subscriptions, to get more details or to CANCEL them.
At the moment, the following subscription services are available:
IP2TOR is a tunnel service where you can run your RaspiBlitz anonymously behind TOR but you rent a port on a clearnet IP through which you can make services of your RaspiBlitz easy reachable for everybody on the internet. You don't need to care about your local router or firewall settings. You can pay for this service directly through Lightning from your RaspiBlitz as subscription.
At first you select what services of your RaspiBlitz you like to tunnel through a IP2TOR bridge.
You will get a list of available IP2TOR bridge offerings.
Select OK on an IP2TOR bridge offering and you will see more details on it, such as how many satoshis the subscription will cost you.
Your node should be funded and have channels open already at this point.
Then you get a list of available IP2TOR bridge offerings.
By selecting OK on a IP2TOR bridge offering you can get more details on it and you will also see how many satoshis the subscription will cost you - your node should be funded and you should have channels open at this point.
If you choose AGREE on the details of a IP2TOR bridge offering the RaspiBlitz tries for you to setup the IP2TOR bridge.
If everything worked you will find now the subscription under MAINMENU > SUBSCRIBE > LIST My Subscriptions where you can cancel it again.
To try out the IP2TOR tunnel choose in MAINMENU the extra menu point of the Service you choose the bridge for and it should give you now an updated URL or try calling the API on the IP and Port that is displayed under the details of the subscription in the LIST My Subscriptions section.
If you want a web service, like BTCPay Server or LNbits, to be available to the outside internet (like with IP2TOR) people expect you to offer an HTTPS address so that the communication between the client and your RaspiBlitz is encrypted. You could use the self-signed HTTPS certificate that RaspiBlitz is offering you, but this will give users Security Warnings in their browser and is not very user friendly. That's where you can use a LetsEncrypt Subscription to get a free valid HTTPS certificate that is excepted without warning from almost all common browsers
Because you also need a domain name for that you will need to open a free account, the following are presently supported, would be good to add more with the help of the community: DuckDNS.org DYNU.com (AT THE MOMENT NOT AVAILABLE)
When you create a new LetsEncrypt subscription, you will be asked for your subdomain on DuckDNS and the auth-token of your DuckDNS account.
Then RaspiBlitz tries to setup everything for you.
If everything worked, you will find the subscription under MAINMENU > SUBSCRIBE > LIST My Subscriptions, where you can cancel it at any time if you wish.
To try out the IP2TOR tunnel, go into MAINMENU and the extra menu point of the Service you want to use the bridge for.
It should give you an updated URL to call your service.
HTTPS can be a hairy topic, you can try using a SSL Checker to help you quickly diagnose problems with your SSL certificate installation: www.sslshopper.com/ssl-checker.html
Change your passwords for security.
The REPAIR menu gives you options to check and reset your RaspiBlitz.
The options are explained in detail below:
This will print out a lot of information that can be used to find software problems.
Use this if you want to report a software problem with your RaspiBlitz, so that others can have a look and help you better.
This stops your RaspiBlitz and creates an LND-Rescue ZIP file that you can download via SCP to your laptop. This can be used to move your LND id, wallet & channels to another RaspiBlitz.
NOTICE: If you start your RaspiBlitz after this backup again the backup is outdated and using it can risk losing your channel funds.
THIS WILL DELETE ALL YOUR LND DATA AND CHANNEL FUNDS. Use this only if you have closed all channels and removed all funds.
Use this option if you want to start with a fresh LND node id & wallet.
Multiple options to repair/backup your c-lightning node:
This stops your RaspiBlitz and creates a Migration ZIP file you can download/export per SCP to your laptop. This contains all the important data from your RaspiBlitz including LND, your Blitz configuration and also data from your installed apps. Can be used to migrate your RaspiBlitz to a new hardware - for example if you want to replace the HDD with a SSD. For details on how to import a Migration File see here.
NOTICE: If you start your RaspiBlitz after exporting the migration file again it is outdated and using it can risk losing your channel funds.
To expedite the setup process, you can connect another RaspiBlitz and copy over your blockchain data to it.
Your RaspiBlitz will be offline during that process and it can take between 4 to 6 hours.
Make sure both RaspiBlitzes are connected to the same local network.
During setup with the new RaspiBlitz, choose the COPY option to get the blockchain data and then select the source computer RASPIBLITZ.
Now you can choose the COPY-SOURCE option, enter the IP address of the new RaspiBlitz and its Password A (not yours), after which the process should start automatically.
Use this option if your blockchain data got corrupted. It will keep your LND data. You can even keep your channels open. Just keep in mind that your Lightning node will appear offline to the network until you have re-downloaded the blockchain.
THIS WILL DELETE ALL YOUR LND DATA AND CHANNEL FUNDS. Use this only if you have closed all channels and removed all funds.
Use this if you want to setup a fresh RaspiBlitz but don't want to re-download the blockchain.
THIS WILL DELETE ALL YOUR LND DATA AND CHANNEL FUNDS. Use this only if you have closed all channels and removed all funds.
Use this if you want to setup a fresh RaspiBlitz with an empty HDD.
If you had Electrum installed, you can use this option to make sure also the space consuming electrum index gets deleted to free up space.
If you had the Bitcoin Transaction Index activated you can use this option to make sure that this extra space consuming index gets deleted as well to free up space.
The UPDATE menu gives you options to update your RaspiBlitz and some apps you might have installed.
The options are explained in detail:
Please note that the RaspiBlitz does not support any form of automatic (over the air) updates. This is to ensure that there can be no remote control of your node from a central server.
This is a common way to update your RaspiBlitz. Choose this option to prepare your RaspiBlitz for a new SD card image containing the new version release.
With Patching you have now an easy way to sync your RaspiBlitz code/scripts with the official RaspiBlitz GitHub Repo or even your own forked GitHub Repo. This is an option for people that report bugs and we like to offer them a quick script update (patch) between RaspiBlitz releases or for people who want to develop on the RaspiBlitz and sync code between their IDE, forked GitHub and their RaspiBlitz.
Sometimes there is a new LND release that has some breaking changes that once you updated the LND database cannot be reversed (like the update from 0.9.2 to 0.10.0). In these cases RaspiBlitz will offer you an optional update. This is where you then can update LND.
If you choose this you get the option to do this VERIFIED that means it offers you the optional LND update we tested the RaspiBlitz with or RECKLESS which will just grab the latest LND release from the GitHub releases page (also Release Candidates) and install it with no further guarantees and verification checks.
The RECKLESS option is aimed at people that run nodes to test new releases and how they work with existing RaspiBlitz apps.
Like with LND you have the ability to update the Bitcoin core version here.
A safe way to restart the RaspiBlitz ... have you tried turning it off and on again?
A safe way to shutdown the RaspiBlitz.
The EXIT option next to OK closes the SSH main menu and exits to the terminal where the user can make use of the CLI clients, bitcoin-cli & lncli, directly.
In the terminal running the command raspiblitz will return you to the SSH main menu.
As mentioned above you can export a Migration File from your RaspiBlitz with MAINMENU > REPAIR > MIGRATION and store it on your laptop.
A Migration file contains all the important data from your RaspiBlitz, like your LND data, Bitcoin Wallet, raspiblitz.config, Tor/SSH keys, and also installed apps. You can use this to migrate your RaspiBlitz to new hardware.
If you want to import it again to a new RaspiBlitz (for example with an updated HDD/SSD), you can choose the FROMBACKUP option on the first setup dialogue of a fresh SD card image.
If you start MIGRATION you be get asked whether you would like to use a existing blockchain on the hard drive/SSD and delete the rest, or whether you'd prefer to format the entire drive.
Once that's done you are shown instructions on how to upload the migration file (use the password raspiblitz when asked on executing the upload command):
After this you will be asked to set a new password A, and your RaspiBlitz will go into recovery/provision process. Then RaspiBlitz might give you the option again to self-sync or copy the blockchain from another computer/blitz, and afterwards a final reboot.
Then the blockchain needs to sync up and you should be back to normal.
Another kind of migration is when you already run a full node with the Umbrel or myNode software and you like to change it to RaspiBlitz without closing channels. You basically have all the hardware needed and just need to change software. You don't need the LCD from the shopping list - RaspiBlitz can also run without an LCD.
NOTE: This migration is still experimental. You will still use the terminal to setup & manage your RaspiBlitz. If that is too technical for you please wait for the RaspiBlitz v1.8, which will introduce a WebUI for your browser that will make the migration to RaspiBlitz more familiar to your old node user experience.
Before you start migration:
- if you have on-chain funds on your old node - make sure to have the backup seed words
- if you have lightning channels open on your old node - make sure to have downloaded the latest Static Channel Backup file to your laptop
Also be aware that at the moment RaspiBlitz can only transfer your blockchain and LND wallet data (including channels) over to RaspiBlitz. Any data/pairing of additional apps cannot be transferred and may get lost.
Instructions for Migration:
- shutdown your old node
- remove the SD card
- download the latest Raspiblitz sd card image & flash it to your sd card
- if you want to use a HDMI monitor for status & progress, create a empty file called
hdmi(without any ending) on the SD card while connected to your laptop - insert sd card, boot up & login by SSH
Now RaspiBlitz should show you that old data from your node was detected and offer to do the migration for you.
- If you choose to continue it will prepare the data & reboot.
- The RaspiBlitz recover/update modus is starting - that will take a while and finally reboot.
- Login by SSH as before and reset the passwords (
FINAL RECOVERY LOGINon LCD). Then a final reboot will happen. - Login by SSH with your new password A & unlock LND wallet with password C. Now blockchain needs to catch up and then your RaspiBlitz should be ready and show you (under INFO) your on-chain & channel balance.
If you don't have an LCD or HDMI monitor connected it might be a bit difficult to see what state your RaspiBlitz is in. Just (re-)try to login by SSH again after the reboots. It can take some time after a reboot before the operating system and SSH service is started, so just keep trying at intervals until successful.
To develop your own scripts/apps and connect other services/apps to your RaspiBlitz you have multiple interfaces/APIs available:
bitcoin-clicommand line interface on the terminalbitcoindrunning on port 8333 (public)JSON-RPCrunning on port 8332 (local) DOC
lnclicommand line interface on the terminal DOClndrunning on port 9735 (public)gRPCrunning on port 10009 (public) DOCRESTrunning on port 8080 (public) DOC
If you activate Tor then your LND gRPC & REST APIs will also be reachable publicly as a Hidden Service.
Since LND v0.6 (and RaspiBlitz v1.2), a feature called Static-Channel-Backups is available.
Within RaspiBlitz this is used when a channel.backup file is mentioned.
At this point in time it is the best way to backup and protect your channel funds on RaspiBlitz, so it's recommended to make use of it.
To recover your funds this way you will need two things:
- the 24-word seed
- the latest
channel.backupfile
You should have written down the word seed during wallet setup; keep it at a safe (offline) location.
The channel.backup is stored on the HDD and updated by LND every time a new channel is opened or closed.
The latest version of this file is needed to recover all your funds.
In case your HDD gets damaged RaspiBlitz always keeps a copy of the latest version of the channel.backup file on the SD card within the sub-directories of: /home/admin/.lnd/data/chain/.
If you want to go one step further in securing your funds against total loss of the RaspiBlitz (gets completely damaged, stolen or lost), then you can additionally set up an off-location or cloud backup of the channel.backup file.
The file itself is encrypted by your word seed so it's acceptable to store the file with untrusted third parties for backup purposes (if you want)
This video explains in detail how you can set further back Static Channel information:
--watch--> https://www.youtube.com/watch?v=5wi6l9jRVQs
The following options are also explained here shortly:
Toggle the StaticChannelBackup option to DropBox in the SETTINGS menu of your RaspiBlitz.
It will ask you for the Dropbox-Authtoken.
This is how you can get this token:
Go to your web browser, do the following:
-
Go to https://www.dropbox.com/developers/apps/create and sign in.
-
Choose Create App.
Choose the 'Scoped Access' & 'App Folder' and set a unique name - for example
LNDbackupwith a random number behind it. Agree to Terms of Service and click 'Create App'. -
Set Permissions.
Its important first to select the
Permissionstab and activate thefiles.content.writepermission. Don't forget toSubmitthe change before continue. -
Generate OAUth2 Token.
Now go back to the 'Settings' tab and under 'OAuth2', choose 'no expiration' under 'Access token expiration' then click the 'Generate' button. You will now see a long string of letters and numbers appear. This is your Dropbox-Authtoken. Make sure to copy the complete token string .. there might be more if you scroll to the right in the token field.
To test it, try opening or closing a channel and then check if you can find a copy of channel.backup in your Dropbox.
You can check the background-script logs to see details on errors: sudo journalctl -f -u background
You can also backup the StaticChannelBackup file to your own server, but this needs manual setup:
In the /mnt/hdd/raspiblitz.conf the parameter scpBackupTarget='[USER]@[SERVER]:[DIRPATH-WITHOUT-ENDING-/]' can be set to activate this feature.
On the remote server, the public key of the RaspiBlitz root user needs to be added to the authorized_keys file so that no password is needed for the background script to make the backup.
The script /home/admin/config.scripts/internet.sshpubkey.sh helps on initialization (init); it will show and transfer ssh-pubkey to a remote server.
To test it, try opening or closing a channel and then check if you can find a copy of channel.backup on your remote server.
You can check the background-script logs to see details on errors: sudo journalctl -f -u background
You can also backup the StaticChannelBackup to another local drive, e.g. a USB stick:
You can use a small USB thumb drive (everything over 120MB is fine). Please don't use a second HDD/SSD for this because that might drain too much power and could hurt the security of your data more than it helps.
To activate this feature, go to MAINMENU > SETTINGS > StaticChannelBackup on USB Drive and follow the instructions.
To test it, try opening or closing a channel and then check if you can find a copy of channel.backup in the specified location.
You can check the background-script logs to see details on errors: sudo journalctl -f -u background
If you have a RaspiBlitz older than version v1.0, please see here.
If you have a RaspiBlitz v1.2 or higher - just follow the UPDATE option from the main menu (choose RELEASE if asked) and follow the instructions - see the process in detail in the following video.
--watch--> https://www.youtube.com/watch?v=Xvn0WQfHUdI
If you have a RaspiBlitz v1.0 or v1.1 or higher do the following:
- Main menu > OFF
- Remove power
- Remove SD card
Now download the new RaspiBlitz SD card image and write it to your SD card. Yes, you simply overwrite the old one -- it's OK! The RaspiBlitz stores all your personal data on the HDD. See details about latest SD card image here.
If you have done manual changes to the system (installed packages, added scripts, etc.), you might need to take some additional steps before overwriting your SD card - see FAQ.
If done successfully simply put the SD card into the RaspiBlitz and power on again.
Then follow the instructions on the display ... and don't worry, you don't need to re-download the blockchain again.
It is worth noting here that your SSH password will be reset to raspiblitz.
You will be prompted to change this once the update is finished.
A ready-to-use SD card image of RaspiBlitz is provided by us for download, to get everybody started quickly (see above). But if you want to build that image yourself - here is a quick guide:
- Get a latest RaspiOS 64-bit: DOWNLOAD.
- Write the image to an SD card: TUTORIAL.
- Add a file called
sshto the root of the SD card when mounted on your laptop to enable SSH login. - Start the card on a Raspi and login via SSH with
ssh pi@[IP-OF-YOUR-RASPI]. Password israspberry.
Now you are ready to start the SD card build script (check the code to see if the installation and config are OK for you). Copy the following command into your terminal and execute:
wget https://raw.githubusercontent.com/rootzoll/raspiblitz/v1.7/build_sdcard.sh && sudo bash build_sdcard.sh
As you can see from the URL, you can find the build script in this Git repo under build_sdcard.sh.
You can check what gets installed and configured in detail.
Feel free to post improvements as pull requests.
The whole build process takes a while.
At the end the LCD drivers get installed and a reboot is needed.
A user admin is created during the process.
Remember the default password is now raspiblitz.
You can login by SSH again - this time use admin: ssh admin@[IP-OF-YOUR-RASPI].
The install dialogue of the RaspiBlitz should automatically start.
If you do not want to continue with the installation at this moment, and use this SD card as a template for setting up multiple RaspiBlitzes, click Cancel and run release.
Once you see the LCD going white and the activity LED of the pi starts going dark you can unplug power and remove the SD card.
You have now built your own RaspiBlitz SD card image.
Note: If you plan to use your self-build SD card as a MASTER copy and distribute it: Use a smaller 8GB card for that. This way it's ensured that it will fit on every 16 GB card recommended for RaspiBlitz later on.
