Storage space: I am using an 8 GB microSD card for the OS, and a 128 GB USB drive for data. Minimums I would recommend: 8GB SD card and 32 GB USB drive.
Reddcoin Core client version: v188.8.131.52-a8767ba-beta (most recent version at this moment). ↳ Screenshot
You need the OS; Lubuntu. Download Lubuntu (707 MB) for the Raspberry Pi: https://ubuntu-pi-flavour-maker.org/download/. It's a .torrent download, so you will need a BitTorrent client. Message me or post in this thread if you need help with this.
You need software to write the OS to the SD card. I use Etcher. Download Etcher: https://etcher.io/.
Select image: select the lubuntu-16.04.2-desktop-armhf-raspberry-pi.img.xz file.
Select drive: select your microSD card.
Plug the SD card into your Raspberry Pi and power it up.
Lubuntu should boot up.
Set up Lubuntu, connect to the internet (wired or wireless). ↳ As username, I chose "rpi3b". You will see this username throughout this whole tutorial.
Make sure date and time are correct ([Menu] > System Tools > Time and Date). ↳ Click on Unlock to make changes. I personally change Configuration to "Keep synchronized with Internet servers". ↳ Screenshot
Reboot ([Menu] > Logout > Reboot). I am connected to wifi, but have issues getting wifi to work on initial boot. A reboot solves this issue.
Make sure system is up-to-date, install never versions.
Open LXTerminal ([Menu] > System Tools > LXTerminal). ↳ Screenshot
Enter the following in LXTerminal: sudo apt update && sudo apt upgrade ↳ Screenshot
You will be asked if you really want to continue. Enter Y (yes).
Updates are being installed! Wait until it's finished.
Install programs that will be used in this tutorial.
GParted: to partition the USB drive.
Htop: to see the amount of memory (RAM) and swap that is in use.
Enter the following in LXTerminal to install these 2 programs. sudo apt install gparted && sudo apt install htop ↳ Screenshot
Create 2 partitions on the USB drive: 1) Swap partition 2) data partition (for the Reddcoin blockchain) The swap partition is necessary: The Reddcoin wallet can be memory intensive. To prevent any crashes or freezes, add 2 GB of 'virtual' memory by creating a swap partition.
Important: Backup your USB drive if needed. The USB drive will be formatted, so the data on the USB drive will be wiped.
Please use the USB drive solely for this purpose, do not combine it with other stuff.
Keep your USB drive plugged in, do not (randomly) plug it out.
Plug your USB drive in.
GParted will be used to create the partititons. Start GParted via LXTerminal: sudo gparted ↳ Screenshot
Apply the changes. Click on the check mark or select Edit > Apply All Operations. ↳ Screenshot ↳ Screenshot
Important: The name of the swap partition is needed later, so please write it down. Mine is /dev/sda1 (first partition on first drive (drive 'a')). ↳ Screenshot
Reboot. After the reboot, the data partition you just created should be visible on your desktop. ↳ Screenshot
The swap partition is created, so now we can enable and use it.
The swap in use can be monitored with the program Htop. Open Htop ([Menu] > System Tools > Htop) to see the 'Swp' (swap) in use. ↳ Screenshot By default, swap is not used, so 0K. ↳ Screenshot You can leave Htop open.
To enable the swap partition, open LXTerminal and enter the following commands: (Assuming /dev/sda1 is your swap partition.)
Unpack the file (large file, takes around 15 minutes to unpack): sudo xz -d bootstrap.dat.xz ↳ Screenshot
After a successful unpack, your will find the file bootstrap.dat in your USB root folder. ↳ Screenshot
On the first run of the Reddcoin Core client, it will ask for a data directory to store the blockchain and wallet data.
Start the Reddcoin Core client: sudo /media/rpi3b/usb/reddcoin/src/qt/reddcoin-qt ↳ Screenshot
The welcome screen will appear and ask you about the data directory. I suggest a new folder on your USB drive, I picked blockchain. The directory will be created with all the necessary files. ↳ Screenshot
Click on the three dots (...) on the right. ↳ Screenshot
Click on Create Folder at the upper right corner. Type and enter in the folder name. (In my case: blockchain.) Click on Open. ↳ Screenshot ↳ Screenshot ↳ Screenshot
After selecting the directory, the Reddcoin Core client will start. Wait till it's fully loaded and close it.
Move the bootstrap.dat file to your data directory you selected in the previous step. By doing this, Reddcoin Core will use the bootstrap.dat file to import the blockchain, which speeds up syncing. sudo mv bootstrap.dat /media/rpi3b/usb/blockchain/ (Assuming blockchain as data directory.) ↳ Screenshot
The Reddcoin Core client set up is completed, but you still have to sync fully with the blockchain before you can send, receive and stake.
Keep the client running until it's fully synchronized. It will use the bootstrap file first, and download the rest of the blockchain to complete the sync. This can take some time (it took 2 days for me). Syncing the blockchain uses a lot of resources, so the software may react slow.
You can see the progress in the debug window (Help > Debug window). ↳ Screenshot
When the synchronization is completed, the red (out of sync) will disappear on the Overview screen! ↳ Screenshot
When synchronization is complete, you can start staking your Reddcoins.
You can write down your private key or copy and save it in a document. Make sure you save it somewhere only you can access it.
To import later: Debug window -> Console -> importprivkey [label] [label] is optional. ↳ Screenshot (without a label) ↳ Screenshot (with a label)
Boot with only 1 USB drive plugged in: Make sure only the USB drive (with the swap partition and data partition) is plugged in when you boot up your Raspberry Pi. This to make sure the swap partition (/dev/sda1) is recognized correctly. If you boot up with multiple USB drives, Lubuntu might see the USB drive with the swap partition as the second drive (instead of the first drive), and ignore the 2 GB swap partition. If this happens, starting Reddcoin can render the Raspberry Pi unresponsive.
Start Reddcoin Core easier Run a shell script (.sh file), so you can start Reddcoin just by double clicking on an icon on your Desktop.
Right Click on your Desktop and select Create New -> Empty File. ↳ Screenshot
Enter a file name, make sure it ends with .sh, and click on OK. I've chosen for Reddcoin.sh. ↳ Screenshot The file will be created on your Desktop. ↳ Screenshot
Add the command to start Reddcoin to the file.
Right click on the file, select Leafpad (to open the file in a text editor). ↳ Screenshot
Add the following to the file and save the file: sudo /media/rpi3b/usb/reddcoin/src/qt/reddcoin-qt ↳ Screenshot
To be able to execute the shell script (.sh), it has to have 'execute permissions'.
Right click on the file, and select Properties. ↳ Screenshot
Click on the Permissions tab.
For Execute, select Anyone, and click on OK. ↳ Screenshot
To start Reddcoin Core, double click on the file. A new window will pop-up, asking you what you want. Execute in Terminal is what we want, so you can click on enter. ↳ Screenshot Reddcoin Core will now start. Do not close the Terminal window, you can minimize it if needed.
Minimization options Adjust minimization options, so you can safely press on the X button (the close/exit button on the upper right corner).
Activate 'Minimize on close'. Settings -> Options... -> Window (tab) -> Minimize on close. ↳ Screenshot Reddcoin will still run when you click on the X button. To close/exit Reddcoin, right click on the Reddcoin icon in the system tray (bottom right corner). ↳ Screenshot
RealVNC VNC Viewer (client) and VNC Connect (server): To remote connect to the Raspberry Pi, I use VNC Viewer ad VNC Connect from RealVNC.
After your download is finished, open the file and click Install Package. ↳ Screenshot
To run the VNC Connect once:
Open [Menu] > Run, and enter: vncserver-x11 ↳ Screenshot
To auto run on startup:
Open Default applications for LXSession ([Menu] > Preferences > Default applications for LXSession). ↳ Screenshot
In LXSessions configuration, select Autostart in the menu left.
Under Manual autostarted applications, enter vncserver-x11 and click on + Add. ↳ Screenshot ↳ Screenshot
Reboot your Raspberry Pi and check if VNC Connect is started automatically after the reboot.
When VNC Connect is running, you'll see a VNC icon on the right bottom corner. Double click the icon to open VNC Connect and to see the IP address you need to enter to connect to your Raspberry Pi. ↳ Screenshot
Just wanted to say that I love you guys! I'm new here, to the whole dogecoin thing, but from the beginning I can see that you guys are awesome! The vibe around dogecoin is so fun and cheerful, and not overtly serious. It's great! We are just throwing DOGE everywhere to each other, to those who are helpful, to those who are funny, etc. I love this feeling of community here. I just love it. I feel that this feeling/vibe of the dogecoin will (and has already!) totally invite a ton of people to all of cryptocurrency. I know for me personally, when I heard of dogecoin I said to myself that I wanted to try mining it. So I set out to learn, and using the doge mining guide (made by someone in the community!) I started to dig for dogecoins (a weasly ~10kH/s but that's alright haha). And then on Reddit, someone tipped me 500 DOGE (Thank you shibeseller !). I felt so happy receiving that I wanted others to feel the same way so I decided to go tip others too! And through this cycle, I feel that we'll grow as a community! So many thanks to all of you guys, for being awesome! I love this whole fun vibe and community of dogecoin. And never ever be overtly serious, you guys! Thanks WiggleBooks (PS whenever I open my Dogecoin wallet, it needs to synchronize (1000 blocks or so). It takes so long for this synchronization process, is there a way to make it sync faster?)
After reading tiny snippets about Bitcoin all the time I decided to take a closer look at it ... and I was floored. Please don't get me wrong, I really really really want to love the concept, but it seems to be more or less unusable. There are some huge upsides to it: Built on mistrust, fixed amount of money, decentralized system, anonymity and so on. But my reality looked something like this:
I read about all the upsides. Sounds awesome, let's get rolling!
Client? Yes, there's a feature matrix, uh, let's just install the Qt client.
Oh great, there's my wallet and an address, this was easy. "Hey buddy, would you send me a tiny amount to test this?" - "Sure!"
What, synchronizing with the network? Just do whatever you want.
My buddy asked if I had gotten the money yet. I haven't.
After two hours: What does this thing do there with all the synchronizing? And where is the money?
Let's read up on the synchronizing. Oh, it downloads the blockchain. Wait, the whole thing? How big is it? Let's see, about 7GB. Let's have some fun with my slow internet connection and my small SSD!
Now let's read some more, can a buy a coffee here with Bitcoins? No. Okay, in the next big city? I can't find a location. Bummer.
Two hours later, the Qt client is still synchronizing? Jeez ...
Now as you might say, I should have read up on the details (blockchain!) before - but getting started seems to be a big hurdle for the non-geeks out there. Nothing like "get started in seconds!". Even I had some trouble grasping the concept, and I'm sitting in front of a computer for about two decades now. But wait, there's more! Since my connection is still under heavy load from the client, I could read up on all the things I have missed, and I found some inherent flaws:
The amount of money is limited, so there will be no hyperinflation. Awesome! But at the same time, there will be a deflation: The number of bitcoins is fixed, but the amount of money put into the system is rising and rising. So looking from a perspective of Bitcoins, you had to pay 10000 BTC for a pizza, but today you'll get one for less than 1 BTC.
Which brings me to the next point: The values are somewhat incomprehensible for "normal" people. Let's assume 1 BTC is worth $130. My coffee would cost about 0.01 BTC, that's a nice number. But as far as I know, the price is expected to go up and in some months my coffee could cost 0.001 BTC - great, now I have to talk about "Millibitcoins". Try explaining that to somebody who even has problems with the decimal places of regular prices ... I thought Bitcoins were all about micropayments?
And regarding that: Transaction fees. As somebody here in /Bitcoin wrote, if you get lots of very small transactions and try do move them together, it will be expensive to do so.
Here in the EU we have some strict regulations about money laundering, as far as I know there are similiar laws in the US. I have read about closed accounts because of small (!) Bitcoin transfers, some countries here still have no idea whether it is legal or not and so on ... so nobody will put money into a system which could be deemed highly illegal the next day.
Because of that, getting money into the system (and out again) is currently a little difficult. But as soon as its in there, it is easy to use - and I don't depend on a bank (I'm sure you've read about the Euro Crisis).
The system currently seems to be a giant speculative market: Buy Bitcoins low, sell them high, profit. For "real" transactions it is hard to use, especially because of the verification delay - as far as I understood, I could send $1 and it could be worth $2 when it arrives. This might be just a matter of time, but who will use a wildly fluctuating currency?
As already mentioned, the ever-growing blockchain might be okay for fast internet connections and big hard disks, but not for me. Even it is necessary, it sucks.
For me, Bitcoins could be an awesome form of worldwide, internet-based form of micropayments. The biggest market would be developing countries. But there are technical and legal barriers which push it into a corner for geeks who see conspiracies everywhere and want to crash the system ... which is exactly not what it should be. I read about Ripple, it seems to be a better alternative just because of the possibility for easy money exchanges - and it includes Bitcoin, too. So, is there something I just don't get yet? I get the impression Bitcoin is a great idea, but just the prototype for something better.
Reddcoin Core 2.1 will be an update to the core components of Reddcoin : reddcoin-qt and reddcoind. One of the key improvements is expected to be a speedup for the blockchain synchronization process - something we read a lot of negative comments about - and understandably so. I have a 2011 vintage laptop which I use for testing. It takes more than a few days to chew through the blockchain sync. Old though it may be, it’s my favorite benchmark of acceptable performance. First let me explain why blockchain sync is slow, then explain what will be done to speed it up. The Reddcoin blockchain is up to block 1760528 whereas Bitcoin is up to block 472265 (as I write this). That the Reddcoin blockchain is 3.7 times longer despite only having been alive since 21 Jan 2014 versus Bitcoin’s birth in 2009 may come as a surprise, until you remember that Reddcoin’s block time of 60s is one tenth’s of Bitcoin’s 10min block time. Under normal operating conditions on recent hardware you are unlikely to notice any performance hit. But the blockchain synchronization process cruelly throws the spotlight on one of the more CPU intensive aspects of maintaining a blockchain - block validation - something every network node does whether a new block is propagating through the network or an old block is being synced from either a bootstrap file or a network peer. Whatever performance issues Bitcoin 0.9 had during blockchain synchronization, Reddcoin necessarily suffers 10x worse. Whilst making Bitcoin comparisons, it’s useful to recall the origins of our current Reddcoin Core 2.0. Reddcoin Core 2.0 is based on Bitcoin 0.9 with the PoSV code from Reddcoin 1.4 reintegrated - work that @Gnasher completed almost a year ago specifically to incorporate the OP_RETURN feature from Bitcoin 0.9 which is a key enabler for Redd-ID. Peering at the Github tea leaves it is evident that synchronization performance was thought to be an issue in Bitcoin 0.9 because there were features introduced in later versions to address specifically this concern. And it is precisely these features we plan to integrate into Reddcoin Core 2.1 as part of the overall strategy of shadowing the Bitcoin code base as and when the need arises to move things forwards. My personal dream is getting SegWit live on Reddcoin, but clearly with rather empty blocks and 10x the capacity of Bitcoin, we’re way off needing something like a Reddcoin Lightening Network yet. But it is good to know we have that option open to us in our future road map. Therefore the work currently underway for Reddcoin 2.1 is expected to include two features that will accelerate the blockchain synchronization process: 1 - “headers first” synchronization taken from Bitcoin 0.10 2 - Removal of the openssl lib dependency and replacing that very generic and slow elliptic curve crypto code with an optimized internal implementation originally developed for Bitcoin 0.12. Whether this work will get Reddcoin Core all the way up to Bitcoin 0.12 remains to be seen. The base target is Bitcoin 0.10 with at least one 0.12 feature. I don’t yet know what kind of speedup we should expect from this, but I am hopeful of something significant. I plan to publish timing comparisons once I have a beta of 2.1 with these features working. Anyone eager to know sooner is welcome to test Bitcoin 0.9 vs. Bitcoin 0.12. Meanwhile with Redd-ID close to entering beta testing and a great mobile wallet team taking shape off the back of the recent upsurge of interest in Reddcoin, we can expect 2017 to be a good year for Reddcoin. Keep on staking !
01-13 07:43 - 'Lost Bitcoin passphrase: Does anyone have any experience with the new recovery tool Passware Forensic Kit?' (self.Bitcoin) by /u/NitrousNed removed from /r/Bitcoin within 5-15min
''' Here's my situation..... I know this is an all too common problem (and you've probably heard a lot of similar stories) but I'd appreciate any advice I can get. I purchased some bitcoins back in 2013. They were in a Bitcoin-QT wallet on my now very old and slow Macbook (which I still have). However, I wrote my passphrase on a piece of paper that is long gone now! I'm well aware that without the passphrase or seed phrase I'm unable to recover the coins. HOWEVER, I might know part of the passphrase - but not too sure. I've now created a new BitcoinCore wallet and have imported the located the wallet.aes.json or wallet.dat file from the old mac (just waiting for the initial synchronization which should be finished in a couple of days. I know it is difficult (if not impossible) to crack the passphrase via brute-force but I just heard about new Forensic software called Passphrase ([[link]2 ) that apparently has the ability to recover lost bitcoin passwords from Bitcoin.info and Bitcoin Core wallet services. It is very expensive (USD$1,095/year) but just wondering if anyone has used it before or knows how effective it will be in my situation. Hoping someone can help!!!!!

My first experience with bitcoin was NOT positive :( + Questions
After seeing an interesting comment on /funny in which bitcoin currency is used to make tips across reddit I started to investigate and learn about the Bitcoin. I had heard about it before but I didn't know how it worked or what I had to do in order to use it. A dozen Bitcoin Wiki entries later I download bitcoin-qt and create my first wallet. The system seemed very easy and straightforward and I had already started to apply for "free starter bitcoins" when I met "synchronization". Now synchronization is not necessarily a deal breaker but it was annoying as hell. I'm using an old computer and it seemed as if it would take at least a day if not more to complete the whole process... and during that time my computer was getting slow as hell. Now I'm quite a tech savy person and I know why in this P2P based system this is important, but for anyone else this would be unacceptable. Imagine elder people or not so tech savy persons trying out the system for the first time and noticing that they can't use it without occupying 2+ GiB of their HardDrive and having to wait a lot. I did not complete the sync and tried to use the multibit instead. But since I had already applied to the Free starter bitcoins on some websites I wanted to keep my old wallet. I try to look for an import/export button but it seems that Bitcoin-qt doesn't support exportation and I needed to use a third party application called pywallet (command line!) to export my wallet and convert it into another plaintext format since the format used by bitcoin-qt was not supported by multibit. And one would assume that the first thing you do when creating such a currency is to define a standard for the wallet and the applications. Again, I know how to use the command line but anyone who doesn't and who just wants to try out the system for the first time would be inmediately turned off by this limitation. These are all issues that need to be fixed and addressed. Also, at the current situation it is much more comfortable and easier to set up an e-wallet than using standalone software on my computer. And if you ask me, it beats the purpose of creating a decentralized currency when in the end the most popular e-wallet services are going to hold most bitcoins and suppose a great security risk. So I ask you: do you know any solutions to the above mentioned problems? Is there any way to reduce the impact by those hindrances? And now to the questions: Since I'm a very inquisitive mind and I'm still very much interested in bitcoins I would like to ask some questions I couldn't find properly answered in the wiki about the nature of the bitcoin system and how exactly it works. I'd be very grateful if you could answer any of the following questions: 1. What exactly is a bitcoin? A string of text? A hash? A file with a string of text? 2. If I'm not mistaken, a bitcoin wallet is made of a public key and a private key. If I want to transfer my wallet from one program to another or a piece of paper... would I need to export or print out the strings of text that form the bitcoins itself or do I just need those two keys? 3. How does the bitcoin system know how much balance is inside an wallet/account. Does it typically ONLY check it against the chainblock or does it also make use of any bitcoin strings stored inside the wallet? 4. Cryptographically speaking... what happens when I transfer bitcoins? Thank you! *Please don't downvote me just because my first experience was negative. I'm still very interested and would like to learn a lot more. * Edit: Thank you very much for all your answers! I can't reply to all of you (mainly because it's very late over here) but I feel that I understand the concept much better and also feel much more comfortable knowing that the only thing I ever need is my private and public key. It makes me care much less about software and wallet.data files, knowing that I can have everything I need written on piece of paper or saved in an encrypted file of my own. Then, when I need to spend bitcoins or check my balance I can use whatever software I deem best at the moment. Thank you!
If you are just getting into Bitcoins and started by installing the Bitcoin wallet on your computer you may notice that the synchronization process with the Bitcoin network is taking up quite some time.
