In the event of a contentious hard fork and a possible coin split, user's wealth may be in danger without a proper "replay protection" being implemented.This holds true even more so when a user runs a lightweight wallet such as Electrum.Electrum's developer Thomas Voegtlin has published a document on how to safely split coins should such event occur.However, this method relies on 3rd party servers that the wallet connects to.In the Bitcoin world, 3rd parties should not be trusted under any circumstances.I'll show you how to overcome this limitation by setting up your own Electrum server.This tutorial is aimed at Mac OS X and Debian-based Linux distributions.It should work with other Linux distros too.Sorry, I don't have a Windows machine.Before you start, make sure to install a full Bitcoin node first and set at least the following minimum options in bitcoin.conf: Use random string generator for rpcuser and rpcpassword.The longer, the better.If you already have bitcoin node installed, you need to reindex the blockchain: When running Bitcoin-Qt it should be enough to just close and reopen the wallet.

It will reindex the chain automatically.ElectrumX developer decided to use newer Python 3 which isn't installed on many operating systems by default.Installing the latest version of Python on Apple's OS X is very easy using homebrew: There are many different options to install Python 3.6 based on your Linux distribution.The latest Ubuntu (16.10 as of now) only comes with Python 3.5.You will have to install the newer version from a 3rd party repository: Some Debian-based distributions may already be shipped with the latest Python.In a case of an error try using the following option instead.If you can't install it from a repository, just compile it from the source code.It should work for most distros.Please note that the compilation will take "forever".However, if your CPU has more than 4 cores, you can speed it up a bit by using make -j8 instead.You will also need to install some Python 3.6 dependencies for ElectrumX.then install some required packages:If the above command gives you an error, try installing it with sudo (try to avoid it as much as possible, though).

Clone the ElectrumX code from a GitHub repository using git: /kyuupichan/electrumx.gitcd electrumx Next, create a data folder where the blockchain data will be stored: To allow Electrum wallets to connect to your server over SSL you need to create a self-signed certificate.Go to the data folder:Follow the on-screen information.It will ask for certificate details such as your country and password.You can leave those fields empty.When done, create a certificate:These commands will create 2 files: server.key and server.crt.When configuring the ElectrumX instance, make sure to add server.key to SSL_KEYFILE and server.crt to SSL_CERTFILE.More on this in the next step.First, make sure a fully validating Bitcoin node is running:If you've installed Bitcoin-Qt the chances are bitcoin-cli is not present.It should output information about your node such as block height, open connections etc.If it doesn't, run the node first.OS X lacks Systemd to manage system services, so we will use UNIX's default svscan instead.Create a service folder that will hold symlinks to ElectrumX scripts.Copy daemontools scripts from the GitHub repo to your home directory:Set up ENV variables within ~/scripts/electrumx/env folder.

Each variable is located in a separate file.Please refer to ElectrumX's documentation or have a look at my settings and change it accordingly.When finished open the log/run file:and edit the log path.In my case it is /Users/bitcoin/ElectrumX/logs, yours may be different.Save the file by pressing ESC and typing :wqa followed by ENTER.Change the permissions for the file so it can be executed:Also, change the permission for another file that executes the server:Initialize svscan process to monitor electrumx services:Add services to the folder:They should be immediately recognized by svscan.Check the last few lines of the log to see whether the service outputs any errors: If it does, check your configuration again.bitcoin tucumanErrors are pretty self-explanatory but if you're stuck, let me know in the comments section.ElectrumX is very resource intensive when it comes to open files so it needs a higher limit:Make sure the limit is set after every restart:If the above method doesn't work, try the following:Restart the service for new changes to take effect.Always wait for the service to be terminated properly by checking with logs.Above commands will only execute when svscan is already initialized.litecoin mining efficiency

You can check the service's status with: Most if not all Debian-based distribution use Systemd by default.Make sure that is the case for your system:If it outputs something like File: '/proc/1/exe' -> '/lib/systemd/systemd' you're good to go.Open a sudo session and copy a service file from the ElectrumX repo to your Systemd directory:Edit the file to match your setup:You need to edit at least ExecStart and User variables.bitcoin mining with nvidia geforceWhen you're happy with the changes, hit ESC and type :wqa followed by ENTER.Create a configuration file for the server: and configure it according to your environment.Please refer to ElectrumX's documentation or have a look at my settings.bitcoin miner für androidIf it gives you no errors, enable the service: You can exit the sudo session now:Say hi to connecting Electrum wallets (via Electrum console) using a banner file.It may contain any information such as your server version, donation address, contacts and even info on other services you offer.dell welcomes bitcoin payment

It's purely up to you.The content of my banner.txt file looks like this:and is located in the data folder ~/electrumx.You can save it to any location and let ElectrumX know via BANNER_FILE variable in either env/ folder or /etc/electrumx.conf depending on your operating system.Don't forget to restart the server after changing any server's settings.If you want to help the network and let others connect to your server, you have to open specific TCP ports.For a default Electrum set up, those ports are 50001 and 50002.On Linux, this can be easily done via iptables:However, Mac OS X users will need to install some kind of firewall.litecoin mining in phpThe built-in one only manages outgoing connections.There are a few options such as Little Snitch but none of them are free to my knowledge.If you know about one, please let me know.Also, don't forget to open ports on your router if applicable.There are too many routers to cover them in this tutorial.
