How to export all private keys from Bitcoin core? : Bitcoin

What's the best way to export private keys from an old Bitcoin QT wallet

I have a backup of an old Bitcoin QT wallet (from 2013-ish). I know the wallet is empty, but I would still like to have a few of the private keys from it (to be able to prove that I was in possession of bitcoins at this time).
What is the best way to export a few private keys from the wallet? I'd rather not download the entire blockchain just to export a few keys.

Exported a private key from bitcoin-qt to omniwallet.org and now the wallet within omniwallet.org says $0.00 when I know for a fact that there is bitcoin on that wallet. /r/Bitcoin

Bitcoin QT keeps crashing on Mac. How do I export my Wallet?

I want to export my wallet and open on a Linux machine. Armory and Bitcoin-QT keep crashing -- I just updated them last week and I'm concerned I won't be able to access my coins.

Trying to export my wallet.dat from Bitcoin-Qt, but one of the receiving addresses (and its private key) seems to have disappeared. What to do?

I'm trying to move from Bitcoin-Qt to MultiBit. After upgrading Bitcoin-Qt to 0.8.1 from 0.7.x (supposedly mandatory upgrade/fix because of Bitcoin protocol issues), it always tells me that the block chain is corrupt and I need to rebuild it. Tried a bunch of things, it still does it whenever I start. This easily takes over a day and I want something more lightweight on my laptop anyway, so I switch to MultiBit.
Got pretty much all my BTC out of my old wallet, but I still want to import the existing private keys and (if possible) transaction records. As I understand, I need to get the keys from wallet.dat in json format, and import them into MultiBit. Should be easy enough, no?
First, I tried taking the output of pywallet and importing it into MultiBit. I choose the file, click the button to import, and it does nothing. (The wallet is several megabytes with lots of txns, so it might not have been prepared to handle that big of a file.) Of course I later learn that I'm supposed to just import the private keys, but pywallet doesn't appear to have an option for that?
So I go to Blockchain.info, and (hesitantly) created a wallet there with my wallet.dat. It works, but the balance is short of what it should be. Since then I sent nearly all of my balance via Bitcoin-Qt with no problem, but my balance right now is 0.0004 in Blockchain and ~0.002 in Bitcoin-Qt. I export my private keys to JSON, but when I try importing them to MultiBit, I get error: "There were missing dates. Have to go back to genesis block." It refuses to let me import it at all.
Nonetheless, it turns out that my Blockchain wallet is missing one of my receiving addresses (and its corresponding private key). This address is over a year old and has been used numerous times...so it's not unused/new and I would really like to keep control of it.
I figure my wallet.dat is corrupted somehow...the Bitcoin/Bitcoin-Qt app itself has always seemed rather flaky for me. (Sometimes it'd spontaneously quit after I sent BTC...doesn't really inspire confidence.) Maybe this is what caused the block chain problems to begin with. But I want to figure out how to recover all the private keys, not just the ones that Blockchain recognizes.
Any ideas or suggestions would be greatly appreciated. Thanks.

Accessing wallet never connected to Bitcoin Core

Hey there,
I've made a rookie error and deposited coins into a wallet which never connected to Bitcoin Core. I get that this is completely my fault, but would appreciate some help if possible.
What I did
I followed the installation instructions listed here for macOS. Everything seemed to run smoothly. I began tinkering with the joinmarket.cfg config and inadvertently set my blockchain_source to no-blockchain. I generated a wallet using the python wallet-tool.py generate command and then listed my addresses using the python wallet-tool.py wallet.jmdat command. I deposited Bitcoin into one of my addresses before realising that I wasn't correctly connecting to Bitcoin Core. When I set the blockchain_source back to bitcoin-rpc I get an error stating Failure of RPC connection to Bitcoin Core. Application cannot continue, shutting down. when attempting to run `python joinmarket-qt.py.
What should I do?
I'm not entirely sure how I am meant to be connecting to Bitcoin Core and if once I do connect, I'll be able to access my funds deposited to the wallet address listed earlier.
Would I be better off somehow exporting this wallet to another program (or whatever that process is)?
Any advice would be appreciated. Let me know if you have any questions.
Cheers!

How-to: setup your multisignature Cold wallet in Bitcoin Core 0.20 (highest security setup)

Last release of Core is amazing !
The main new feature is sortedmulti descriptor. This allows you to import your multisig setup in Core almost as if it was Electrum when combine to the new PSBT export in GUI !
As it needs command line and some weird checksum, you also need to input very long command in the console and if you made a mistake, you cannot copy the last command you made. So take your time when the commands are long to check everything and don't miss anything, use copy paste before validating the long command. You only have to do this once fortunately :)
I detail here how you do it with a k of n setup, good luck:
And you are DONE ! You should get the exact same addresses than Electrum and you can created receiving addresses in Qt ! To send money, just go to the send section, use the new coin control feature and export a partially signed transaction. You can use HWI or Electrum to sign it with your hardware wallets !
Notice: You can import more or less than 2000 addresses of each type. If less, blockchain rescan is faster but you may need to redo what we have done here later when all addresses will have been used once. If more, it is the contrary.

You now have the most possibly secure setup in one software: multisig with hardware on the full node wallet. When Bitcoin Core 0.21.0 will be out, we will also have native descriptor wallet so maybe we will have HD version of this. But for now, this is the best you can do ! Enjoy :)

P.S. : if you like doing things in one shot you can do the last two steps in one big command: importmulti '[{"desc": "wsh(sortedmulti(k,[path1]xpub1.../0/*,[path2]xpub2.../0/*,...,[pathn]xpubn/0/*))#check_sum0", "timestamp": birth_timestamp, "range": [0,2000], "watchonly": true, "keypool": true}, {"desc": "wsh(sortedmulti(k,[path1]xpub1.../1/*,[path2]xpub2.../1/*,...,[pathn]xpubn/1/*))#check_sum1", "timestamp": birth_timestamp, "range": [0,2000], "watchonly": true, "internal": true}]'

Reddcoin (RDD) 02/20 Progress Report - Core Wallet v3.1 Evolution & PoSV v2 - Commits & More Commits to v3.1! (Bitcoin Core 0.10, MacOS Catalina, QT Enhanced Speed and Security and more!)

Reddcoin (RDD) Core Dev Team Informal Progress Report, Feb 2020 - As any blockchain or software expert will confirm, the hardest part of making successful progress in blockchain and crypto is invisible to most users. As developers, the Reddcoin Core team relies on internal experts like John Nash, contributors offering their own code improvements to our repos (which we would love to see more of!) and especially upstream commits from experts working on open source projects like Bitcoin itself. We'd like tothank each and everyone who's hard work has contributed to this progress.
As part of Reddcoin's evolution, and in order to include required security fixes, speed improvements that are long overdue, the team has up to this point incorporated the following code commits since our last v3.0.1 public release. In attempting to solve the relatively minor font display issue with MacOS Catalina, we uncovered a complicated interweaving of updates between Reddcoin Core, QT software, MacOS SDK, Bitcoin Core and related libraries and dependencies that mandated we take a holistic approach to both solve the Catalina display problem, but in doing so, prepare a more streamlined overall build and test system, allowing the team to roll out more frequent and more secure updates in the future. And also to include some badly needed fixes in the current version of Core, which we have tentatively labeled Reddcoin Core Wallet v3.1.
Note: As indicated below, v3.1 is NOT YET AVAILABLE FOR DOWNLOAD BY PUBLIC. We wil advise when it is.
The new v3.1 version should be ready for internal QA and build testing by the end of this week, with luck, and will be turned over to the public shortly thereafter once testing has proven no unexpected issues have been introduced. We know the delay has been a bit extended for our ReddHead MacOS Catalina stakers, and we hope to have them all aboard soon. We have moved with all possible speed while attempting to incorproate all the required work, testing, and ensuring security and safety for our ReddHeads.
Which leads us to: PoSV v2 activation and the supermajority on Mainnet at the time of this writing has reached 5625/9000 blocks or 62.5%. We have progressed quite well and without any reported user issues since release, but we need all of the community to participate! This activation, much like the funding mechanisms currently being debated by BCH and others, and employed by DASH, will mean not only a catalyst for Reddcoin but ensure it's future by providing funding for the dev team. As a personal plea from the team, please help us support the PoSV v2 activation by staking your RDD, no matter how large or small your amount of stake.
Every block and every RDD counts, and if you don't know how, we'll teach you! Live chat is fun as well as providing tech support you can trust from devs and community ReddHead members. Join us today in staking and online and collect some RDD "rain" from users and devs alike!
If you're holding Reddcoin and not staking, or you haven't upgraded your v2.x wallet to v3.0.1 (current release), we need you to help achieve consensus and activate PoSV v2! For details, see the pinned message here or our website or medium channel. Upgrade is simple and takes moments; if you're nervous or unsure, we're here to help live in Telegram or Discord, as well as other chat programs. See our website for links.
Look for more updates shortly as our long-anticipated Reddcoin Payment Gateway and Merchant Services API come online with point-of-sale support, as we announce the cross-crypto-project Aussie firefighter fundraiser program, as well as a comprehensive update to our development roadmap and more.
Work has restarted on ReddID and multiple initiatives are underway to begin educating and sharing information about ReddID, what it is, and how to use it, as we approach a releasable ReddID product. We enthusiastically encourage anyone interested in working to bring these efforts to life, whether writers, UX/UI experts, big data analysts, graphic artists, coders, front-end, back-end, AI, DevOps, the Reddcoin Core dev team is growing, and there's more opportunity and work than ever!
Bring your talents to a community and dev team that truly appreciates it, and share the Reddcoin Love!
And now, lots of commits. As v3.1 is not yet quite ready for public release, these commits have not been pushed publicly, but in the interests of sharing progress transparently, and including our ReddHead community in the process, see below for mind-numbing technical detail of work accomplished.

Whew! No wonder it's taken the dev team a while! :)
TL;DR: Trying to fix MacOS Catalina font display led to requiring all kinds of work to migrate and evolve the Reddcoin Core software with Apple, Bitcoin and QT components. Lots of work done, v3.1 public release soon. Also other exciting things and ReddID back under active dev effort.

Groestlcoin 6th Anniversary Release

Introduction

Dear Groestlers, it goes without saying that 2020 has been a difficult time for millions of people worldwide. The groestlcoin team would like to take this opportunity to wish everyone our best to everyone coping with the direct and indirect effects of COVID-19. Let it bring out the best in us all and show that collectively, we can conquer anything.
The centralised banks and our national governments are facing unprecedented times with interest rates worldwide dropping to record lows in places. Rest assured that this can only strengthen the fundamentals of all decentralised cryptocurrencies and the vision that was seeded with Satoshi's Bitcoin whitepaper over 10 years ago. Despite everything that has been thrown at us this year, the show must go on and the team will still progress and advance to continue the momentum that we have developed over the past 6 years.
In addition to this, we'd like to remind you all that this is Groestlcoin's 6th Birthday release! In terms of price there have been some crazy highs and lows over the years (with highs of around $2.60 and lows of $0.000077!), but in terms of value– Groestlcoin just keeps getting more valuable! In these uncertain times, one thing remains clear – Groestlcoin will keep going and keep innovating regardless. On with what has been worked on and completed over the past few months.

UPDATED - Groestlcoin Core 2.18.2

This is a major release of Groestlcoin Core with many protocol level improvements and code optimizations, featuring the technical equivalent of Bitcoin v0.18.2 but with Groestlcoin-specific patches. On a general level, most of what is new is a new 'Groestlcoin-wallet' tool which is now distributed alongside Groestlcoin Core's other executables.
NOTE: The 'Account' API has been removed from this version which was typically used in some tip bots. Please ensure you check the release notes from 2.17.2 for details on replacing this functionality.

How to Upgrade?

ALL NEW - Groestlcoin Moonshine iOS/Android Wallet

Built with React Native, Moonshine utilizes Electrum-GRS's JSON-RPC methods to interact with the Groestlcoin network.
GRS Moonshine's intended use is as a hot wallet. Meaning, your keys are only as safe as the device you install this wallet on. As with any hot wallet, please ensure that you keep only a small, responsible amount of Groestlcoin on it at any given time.

ALL NEW! – HODL GRS Android Wallet

HODL GRS connects directly to the Groestlcoin network using SPV mode and doesn't rely on servers that can be hacked or disabled.
HODL GRS utilizes AES hardware encryption, app sandboxing, and the latest security features to protect users from malware, browser security holes, and even physical theft. Private keys are stored only in the secure enclave of the user's phone, inaccessible to anyone other than the user.
Simplicity and ease-of-use is the core design principle of HODL GRS. A simple recovery phrase (which we call a Backup Recovery Key) is all that is needed to restore the user's wallet if they ever lose or replace their device. HODL GRS is deterministic, which means the user's balance and transaction history can be recovered just from the backup recovery key.

ALL NEW! – GroestlcoinSeed Savior

Groestlcoin Seed Savior is a tool for recovering BIP39 seed phrases.
This tool is meant to help users with recovering a slightly incorrect Groestlcoin mnemonic phrase (AKA backup or seed). You can enter an existing BIP39 mnemonic and get derived addresses in various formats.
To find out if one of the suggested addresses is the right one, you can click on the suggested address to check the address' transaction history on a block explorer.

ALL NEW! – Vanity Search Vanity Address Generator

NOTE: NVidia GPU or any CPU only. AMD graphics cards will not work with this address generator.
VanitySearch is a command-line Segwit-capable vanity Groestlcoin address generator. Add unique flair when you tell people to send Groestlcoin. Alternatively, VanitySearch can be used to generate random addresses offline.
If you're tired of the random, cryptic addresses generated by regular groestlcoin clients, then VanitySearch is the right choice for you to create a more personalized address.
VanitySearch is a groestlcoin address prefix finder. If you want to generate safe private keys, use the -s option to enter your passphrase which will be used for generating a base key as for BIP38 standard (VanitySearch.exe -s "My PassPhrase" FXPref). You can also use VanitySearch.exe -ps "My PassPhrase" which will add a crypto secure seed to your passphrase.
VanitySearch may not compute a good grid size for your GPU, so try different values using -g option in order to get the best performances. If you want to use GPUs and CPUs together, you may have best performances by keeping one CPU core for handling GPU(s)/CPU exchanges (use -t option to set the number of CPU threads).

ALL NEW! – Electrum Personal Server

Groestlcoin Electrum Personal Server aims to make using Electrum Groestlcoin wallet more secure and more private. It makes it easy to connect your Electrum-GRS wallet to your own full node.
It is an implementation of the Electrum-grs server protocol which fulfils the specific need of using the Electrum-grs wallet backed by a full node, but without the heavyweight server backend, for a single user. It allows the user to benefit from all Groestlcoin Core's resource-saving features like pruning, blocks only and disabled txindex. All Electrum-GRS's feature-richness like hardware wallet integration, multi-signature wallets, offline signing, seed recovery phrases, coin control and so on can still be used, but connected only to the user's own full node.
Full node wallets are important in Groestlcoin because they are a big part of what makes the system be trust-less. No longer do people have to trust a financial institution like a bank or PayPal, they can run software on their own computers. If Groestlcoin is digital gold, then a full node wallet is your own personal goldsmith who checks for you that received payments are genuine.
Full node wallets are also important for privacy. Using Electrum-GRS under default configuration requires it to send (hashes of) all your Groestlcoin addresses to some server. That server can then easily spy on your transactions. Full node wallets like Groestlcoin Electrum Personal Server would download the entire blockchain and scan it for the user's own addresses, and therefore don't reveal to anyone else which Groestlcoin addresses they are interested in.
Groestlcoin Electrum Personal Server can also broadcast transactions through Tor which improves privacy by resisting traffic analysis for broadcasted transactions which can link the IP address of the user to the transaction. If enabled this would happen transparently whenever the user simply clicks "Send" on a transaction in Electrum-grs wallet.
Note: Currently Groestlcoin Electrum Personal Server can only accept one connection at a time.

Where can I import my wallet.dat?

Hello!
I am fairly new to Bitcoin, but one year ago, I made a Bitcoin address on Bitcoin-Qt, but I stopped using it, because the whole database downloading took so much space on my disk.
I have my wallet.dat file, but I don't know, where can I use it. I tried Electrum, but it seems that the wallet.dat import doesn't work there.
Can you recommend me any other wallets, where I can import that file?
Thank you.

[TUTORIAL] -- How to SAFELY Claim New RNG Coins Using Your Private Keys

https://preview.redd.it/u4x1o4p37zc41.png?width=700&format=png&auto=webp&s=01d1ff52c0b7fc1c9ae5bb4f161979ad1f4bb559
I’m a longtime blockchain enthusiast and developer and one of my biggest gripes about this space is how quickly every new project is widely dismissed as a “scam” or “shitcoin” by so many people before it even gets off the ground. Sure, there is a lot of uncharted territory with pirates lurking to steal your bags left and right but with a small amount of personal education you can exist safely in the world of crypto I promise! With this article I aim to help lift your knowledge a little higher while helping keep your funds a little safer!

So What Is Happening?

On Tuesday February 18, 2020 a new coin named Ring (RNG) will be minted. This coin aims to bring two unique and fresh methods of proofing to the crypto game, quite literally: Agent-Based Hive Mining (borrowed from LCC) and Proof-of-Play Mining, where literal gameplay is used to hash and reward miners! To celebrate and help spread the word, the team is giving away claims of free RNG to all holders of the following coins:
  • Litecoin Cash (LCC)
  • Bitcoin (BTC)
  • Dash (DASH)
  • Dogecoin (DOGE)
It's being touted as the world's first crypto "4-way fork" but I'd really call it more of a "4-way claim" since its a brand new chain and not based on the code of any of the rewarded coins. It's simply a clever method of allowing a wider range of coin holders a chance to participate in the launch of these exciting new features!

How Will This Process Work?

On the 18th of February, a balance snapshot will be taken of the four chains listed above. Anyone holding a balance with any of these coins at the time of the snapshot will be forever eligible to claim their RNG at any time. Because the only way to prove ownership of a crypto address is to supply the private keys, and pretty much EVERYONE will tell you to guard those things with your life, below I will outline exactly what to do so there is absolutely 0% risk of losing a single satoshi! This method will apply to ANY claim rewards of any coin in the future as well. Always practice #SafeForking!

How Do I Safely Claim My RNG?

STEP 1 -- BEFORE THE SNAPSHOT -- VERIFY ACCESS TO YOUR PRIVATE KEYS
All core wallets will allow you to export a private key of any address in your wallet but many third party services like exchanges and hot wallets do not allow access to them. In these cases you will need to send your funds out of the third party service and into some kind of personal wallet where you can reach the private keys yourself. Then just wait for the snapshot to happen…
To make things easier on yourself, you can optionally collect your original coins into as few addresses as possible BEFORE the snapshot. Doing so reduces the number of keys you will need to empty and import later. It’s just less work!
\** SNAPSHOT HAPPENS HERE... ****
STEP 2 -- ATER THE SNAPSHOT -- EMPTY ALL ADDRESSES YOU WISH TO CLAIM
After the snapshot is confirmed, withdraw all coins OUT of each of your origin coin addresses into brand new addresses leaving the original ones quite empty. This way when you import later there is NO risk of losing anything! Also know that after you import these private keys you should never use them again for safety’s sake! It’s kind of the whole reason you’re even reading this article in the first place.
STEP 3 -- EXPORT PRIVATE KEYS FOR ALL ADDRESS YOU WISH TO CLAIM
This is the most difficult part, are you ready? Once each claim address is confirmed to be EMPTY, you must obtain each one’s private keys. This will entirely depend on the wallet you use (QT example below) but for all core wallets there is generally an option for exporting private keys somewhere in there. Collect them all!
How to Export QT Wallet Private Keys:⛔️ — DISABLE INTERNET FOR SAFETY — ⛔️- Open the QT wallet client- Click on HELP in the menu bar- Click on DEBUG WINDOW- Click on the CONSOLE tab- Click inside the input box at the bottom(if your wallet is locked…)- Type: walletpassphrase [Password] 600(this unlocks your wallet for 10 minutes)- Type: dumpprivkey [Address]- Copy the output hash, paste it into a list somewhere.(repeat as needed, clear your clipboard history after)- Type: walletlock (if applicable)⚡ — RE-ENABLE YOUR INTERNET —
STEP 4 -- IMPORT ALL PRIVATE KEYS INTO RNG CORE WALLET
\** PLEASE VERIFY THAT EVERY CLAIM ADDRESS IS EMPTY BEFORE CONTINUING... ****
The final step is to simply import each of these private keys into the new Ring Core Wallet to claim your free RNG rewards. The wallet handles this part automatically and you will see your new RNG balance right away. You can find this option under the File > Import Private Keys menu.
Importing a private key is the only way to prove ownership of a crypto address so this is unavoidable if you want to claim new coins from it. The steps above will allow you to prove ownership of your snapshotted address balance plus use its empty key to then claim your new coins thus keeping your original coins completely protected in the brand new address with a new private key (which you should now also keep VERY private!)
By emptying the address before you import it’s private key you eliminate the risk of theft entirely. One cannot take from an already empty jar. It should also be noted to NEVER use the imported address again as an added safety precaution*!*
👏👏👏 DONE! ENJOY YOUR FREE MONEY! 👏👏👏

How Much RNG Will I Receive?

Litecoin Cash holders will receive the highest claim ratio (5000 LCC = 1 RNG) as the LCC team are the ones responsible for creating Ring and wanted to extend a heart-felt thank you to the LCC community for their years of support. All other coins will be based on a 1:1 ratio with the value of Bitcoin at the time of the fork. This of course means 1 BTC = 1 RNG. For DASH and DOGE, however, their BTC market prices will determine their reward ratios. (For example if DASH is trading at 0.015 BTC each, then each DASH coin will net you a reward of 0.015 RNG to match.) Of course you don't need whole coins to claim, partial decimals work just fine!

What Value Will RNG Have?

That, my friends, is entirely up to the markets. No one in the history of crypto has had a perfect track record of price predictions so I'm not even going to try here. I will say, though, having gotten to play with their Testnet a bit so far that I am very impressed with the new Proof-of-Play method and how they have initially implemented it. It bodes very good things for the future of their project and this coin so I personally would expect its value to hold and most likely rise steadily as more people become aware of this groundbreaking new tech and it's potential to expand outward!

Is Litecoin Cash Still Going To Exist?

Absolutely! At least, from what I can gather. LCC has it's own purposes and will continue to be developed on. Ring is not meant to be a replacement or upgrade of any kind to Litecoin Cash. It is an entirely different proofing algorithm and a different mission statement altogether. It's more so meant to help expose the amazing new technologies developed on the LCC blockchain to a wider audience beyond simply its own fan base. If anything it'll act a sister chain that can help expose more folks to LCC in the future!

Disclaimer

While I am a moderator for the Litecoin Cash Discord server, I am writing this from an independent point of view as an educated crypto enthusiast with a passion for helping others navigate these waters. Having been an initial forker and third party developer on top of LCC myself, I feel I have some valuable insight into the direction the team is taking and I wanted to offer some sound advice for the upcoming Ring fork before the FUD gets caked on too thick.
I know a lot of people get scared easily in crypto because of the rampant scamming that goes on but I've watched this team work their asses off for two years to get out from under the stain of Charlie Lee's very biased, uneducated "its a scam" tweet which was endlessly parroted throughout the Litecoin community with nothing but blind party loyalty and no due diligence. The LCC folks are kind, wonderful hard-working people with big hearts and ambition and they have actually developed a unique proofing methodology that is likely going to impress a lot of people!
So before you go jumping on the "it's just another shitcoin" bandwagon please stop and take a real hard look at both Litecoin Cash (LCC) and Ring (RNG): two viable projects with something to bring to the table! If nothing else, hey, just claim your new coins and dump them off for some free money. You literally cannot lose if you PRACTICE SAFE FORKING!!!
Good luck, cryptonauts!

Need help having one wallet on multiple computers...any guides or saints available?

It's pretty self explanatory...with all the new emphasis about keeping your in your own storage and not online, I'm trying to make the move.
However, I'm having a hard time with it because I liked being able to access the online wallet from any of my computers.
I can't find a clear step by step guide of this process, every one I've seen assumes you already know where everything is and what every value means...I don't. I need an idiot's approach to this.

Blockchain and BitCoin QT sharing same wallet...

So I started out with a blockchain.info wallet, which I got on very well with: using easily, web access, client side encryption etc...
I then ventured into BitCoin QT, which I downloaded and synced with the swarm, but now I have two wallets...
What I am wondering, is am I able to export my blockchain.info wallet.dat, into BitCoin-QT so that I am running a single wallet in bit instances?? (Also would prefer not to switch blockchain to the wallet setup in BitCoin-QT which I know you can do (importing into blockchain.info) - basically I would like to export my blockchain.info wallet...
Also, might I run into any issues if I manage to do the above?
I am running BitCoin-QT on OSX if that is of any significance...
Thanks!

(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.
     

Overview

 

Steps

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
     

Video

https://www.youtube.com/watch?v=Snr5e8bzftI
This video shows how long it takes to start Reddcoin Core.   TL;DR:
     

Extra

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.
