In this tutorial we will show you how to install and configure Bitcoin Core Wallet on Ubuntu 16.04 LTS.For those of you who didn’t know, Bitcoin Core is programmed to decide which block chain contains valid transactions.The users of Bitcoin Core only accept transactions for that block chain, making it the Bitcoin block chain that everyone else wants to use.It is these users who keep Bitcoin decentralized.They individually run their own Bitcoin Core full nodes, and each of those full nodes separately follows the exact same rules to decide which block chain is valid.This article assumes you have at least basic knowledge of linux, know how to use the shell, and most importantly, you host your site on your own VPS.The installation is quite simple and assumes you are running in the root account, if not you may need to add ‘sudo’ to the commands to get root privileges.I will show you through the step by step installation Bitcoin Wallet on a Ubuntu 16.04 (Xenial Xerus) server.Step 1.First make sure that all your system packages are up-to-date by running these following apt-get commands in the terminal.sudo apt-get update sudo apt-get upgrade12--Step 2.

You will just burn through Azure credits.Purchasing a $30 USB device is ~100000x faster.TL;DR The commands to create a machine in Azure to CPU mine are at the bottom.I have been playing with the blockchain lately, most notably the programmable blockchain Ethereum.I was interested in seeing how difficult it was to set up a machine to mine Bitcoin.What I discovered through my research was that it is possible, but pointless to do CPU mining in the cloud.Why is mining on Azure bad?While it is easy to set it up, CPU mining is extremely inefficient.Mining on CPUs was depreceated a long time ago when it was discovered that it was faster to do on GPUs.But now even GPUs have been deprecated in favor of power efficient ASIC machines /bitcoin-mining-hardware/ There are even cheap USB devices that you can plug in that give you GIGAhashes/second How did my Azure miner go?My 2 core Azure machine costs $85/month, and doing CPU only getting me 4.24+4.25= 8.5 kilohash/second (0.0000085 GH/s), compare that to the 3.6 GH/s that an ASIC $30 USB device provides.

And after 2 days of mining I didn’t even get a single hash even accepted by the mining pool, effictivelly making my mining worth 0%.Could this be faster?free bitcoin 1btcOn Azure, renting servers with a faster CPU (D & G-Series) would net negligble increases due to CPU mining.bitcoin growth fund redditThe upcoming N-Series of VMs will have dedicated GPUs attached that you can offload work to.bitcoin ati radeonThis would be an order of magnitude faster in mining.bitcoin zeppelin/2015/09/29/microsoft-puts-gpu-boosters-on-azure-cloud/ The price per hour of a N-Series VM would be so high that you would be better off just paying to rent dedicated ASIC bitcoin mining rigs e.g.ethereum vpn

To follow this tutorial, basic Linux/Unix command line experience is recommended, but probably not a requirement.Note that Bitcoin technology is generally experimental, and so is this tutorial, so don't use any significant amount of BTC with any system that you setup while following this tutorial.Also note that the relatively weak system that forms a Raspberry Pi 1 or 2, may or may not be able to handle the task of acting as a Bitcoin node satisfactorily.Prerequisites A Raspberry Pi, model B, rev 2 or model B+.Unfortunately the compiling process needs the 512 MB RAM that these models have, but it may be possible to compile on a 512 MB model, and then move the SD card to a model with 256 MB RAM afterwards.SD card of at least 32 GB (it must be large enough to hold the entire block chain).A clean install of the Raspbian OS on the SD card.Raspbian is a version of Debian Linux for the Pi.Network cable, and possibly a case for the Pi, and a keyboard and mouse, unless you plan to ssh into the Pi from another computer.

Initial steps In order to compile and run, Bitcoin Core depends on some other tools which must be installed prior to compiling.Most are available from the Raspbian repositories and are easily installable via apt-get.Install Raspbian on your SD card, if you haven't done so already.Log into a command line on your Raspberry Pi, either via attached keyboard or make an ssh connection to it.Run the Pi configuration tool: In the menu, choose to expand the file system.Then, in "Internationalisation options", choose "Change locale", then in the list make sure that at least "en_US.UTF-8 UTF-8" is checked ("en_GB.UTF-8 UTF-8" should be checked already).Choose "OK" to build the locales.Exit the Pi configuration tool and select yes when it asks to reboot.Otherwise, reboot from the command line with sudo reboot Change the password for your user from the default into a strong password.The is especially important if you want to run a full node and thereby run a computer connected to the Internet 24/7.

But it's advised to change it anyway: Update your Raspbian system by issuing the two commands: Install some dependencies: If you want the graphical frontend, also install the following dependencies.If you just want bitcoind, you can skip this step.Create a directory which we will use for downloading and compiling various stuff, then enter it: Compiling and installing Berkeley DB 4.8 Compiling Bitcoin Core requires the Berkeley DB version 4.8 which is not available in the Raspbian repositories, so we must compile and install it manually.Note that if you don't need a wallet (i.e.if you want to run a headless Bitcoin node and keep your wallet elsewhere) you can completely skip this section and jump directly to downloading and compiling Bitcoin Core.Download the Berkeley DB, uncompress it, and cd into the uncompressed directory: Then, configure the system for compiling, do the actual compile job with make (will take a good while), and then install Berkeley DB: Downloading and Compiling Bitcoin Core We're now ready to download and compile Bitcoin Core itself.

Go to the branches list on the Bitcoin Core project site, locate the latest version number, and substitute "0.9.3" in the command below with that.This tutorial is known to work with version 0.9.3, but a newer version is recommended if there is one.The following three commands will configure the system for compilation, then do the actual compile job.The last command make will probably take several hours to complete.Note: If you skipped the Berkeley DB 4.8 dependency above because you don't need a wallet, you must add "--disable-wallet" (without the quotation marks) to the end of the line that starts with ./configure above.Installing and Running Bitcoin Core To install the compiled Bitcoin Core on the system, perform the following command: After that, you will be able to run Bitcoin Core from anywhere on the system by simply typing: bitcoind (the text based backend) or bitcoin-qt (the graphical frontend).If you want to automatically start bitcoind on startup, e.g.if you want to set up a headless Bitcoin node, add the following line to the file /etc/rc.local: Add the line anywhere before the already existing exit 0 line.

You can run a text based editor by typing "sudo nano /etc/rc.local", or a graphical text editor (if you're working in a graphical environment) by typing "sudo gedit /etc/rc.local", then pasting the script above and saving (in Nano, save and exit with Ctrl-X, then Y, then Enter).Now the bitcoind daemon will start when the system boots.Open the port for Bitcoin traffic If you followed this tutorial to run a full Bitcoin node, don't forget to forward traffic on port 8333 to the Raspberry Pi.How to do this varies from network to network, but typically involves entering the web interface of your network router or modem, and setting up "Port Forwarding" there.Typically this is done by simply adding the local IP address of the Raspberry Pi along with port number 8333 to a list of forwarded ports.Refer to the documentation from your router/modem's manufacturer on how to do this exactly.Some routers even do this automatically so you don't need to do anything.In order to find your Raspberry Pi's local IP address (assuming you're not connecting to it via SSH in which case you already have the IP address), log in to it and run the command: Look for the line that starts with the word inet.

So if the line starts with "inet 192.168.1.106/24", your IP address is "192.168.1.106".You can verify that it works by checking the amount of connections after having run Bitcoin Core for a while.If it goes above 8 connections, you have successfully forwarded traffic on port 8333 to your Pi.Conclusion This concludes this tutorial on how to set up a recent version of Bitcoin Core on a Raspberry Pi.You should now be able to "sudo reboot" your Pi, whereafter it starts bitcoind and begins to download the blockchain.You can always check the status of bitcoind by logging in and typing "bitcoind getinfo".In the future I might offer an almost ready-to-run .img file that you can just transfer to an SD card, make a few easy adjustments, and then you're ready to go, without the need for compiling any software.Although this will make it much easier to set up a Raspberry Pi Bitcoin node, it has the disadvantage that you will have to trust me not to have altered the software to do bad things.Suggestions and comments are welcome.
