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
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 !
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.
Bitcoin Core installation binaries can be downloaded from bitcoincore.org and the source-code is available from the Bitcoin Core source repository.. 0.19.0 .1リリースノート. Bitcoin Core バージョン 0.19.0.1 は以下から入手可能です。 Maybe this speed slowness is to some extent one of the reasons for the emergence of the magento / async-import project. A direct solution to the database can be a cardinal solution for increasing the speed of import, but in this case all the “bugs” related to Magento extensibility are lost - you have to do everything “extended” yourself. I just installed Bitcoin last night, synchronizing blocks is taking forever, I've been hanging at 87% since last night. My question - I have... Bitcoin Core is supported and extensively tested on operating systems using the Linux kernel, macOS 10.10+, and Windows 7 and newer. It is not recommended to use Bitcoin Core on unsupported systems. Bitcoin Core should also work on most other Unix-like systems but is not as frequently tested on them.
