MarketC - Masternode Setup Guide

Transcription

1 MarketC - Masternode Setup Guide Preface In this guide we will be focusing on setting up a masternode for Marketc (CMK). This guide will focus on a typical "hot node" / "cold wallet" scenario. The "hot node" will be a Linux VPS, running just the daemon of the coin, while the "cold wallet" will be your Windows (or macos) GUI Wallet. Requirements You will need some basic understanding on how to edit a text file and how a cryptocurrency wallet works. You will need 1000 CMK for the Masternode Collateral, preferably 1001 to cover up fees. You will need a Linux VPS that is up & running 24/7. o We recommend Digital Ocean for new setups 1 o You can also use Vultr o As with anything in life, you get what you pay for. Other providers should work the same, but be wary of very cheap ones, as they often crash or have very poor performance. We can not offer much support if you chose another provider. A SSH Client - we recommend PuTTY for Windows. macos has an in-built client which you can use by opening the Terminal.app.

2 Open the «debug console» in the menu : Tools -> Debugg console Type the following command : 1. getnewaddress node1 The console gives you an address of this type : «LKAjwC6Eq3JTb9amdWugNWMbVSxYmDcH5M» InformationFor infomation : The address created here is «node1» Type the following command : 1. masternode genkey The console gives you a key. ex : 5kGKmNsRHqWTztyfKxv9vD6V9W9B79F9JenuKL2do1hTuDsVAoc

3 Save these information in a text file. Send on the address created previously (in our example : LKAjwC6Eq3JTb9amdWugNWMbVSxYmDcH5M) 1000 CMK. Attention, the 1000CMK must be sent in one transaction! WarningIf you have multiple wallets, regroup the 1000CMK on an unique address and use it to make the 1000 CMK transaction on LKAjwC6Eq3JTb9amdWugNWMbVSxYmDcH5M The transaction will be confirmed. InformationThe transaction must have at least 15 confirmations for the masternode to be enabled. You should have these 15 confirmations once the tutorial completed.

4 2. Etape ImportantIt would be a shame to lose your investment and your wallet, in order to overcome that, I advise you to encrypt and save it. To do this, go to the top menu: Settings -> Wallet Encryption WarningCaution: Encryption is an irreversible procedure and loss of password means loss of the wallet Dismiss alert

5 Information Depending on the power of your computer, it may take several minutes, do not panic! Restart your wallet at the end of the encryption Once you have restarted, simply go to the top menu: File -> Save wallet Save the file on several USB sticks to not lose it

6 Masternode setup Online server This step can be ignored if you already have an available server connected to a permanent and stable internet connection.

7 We will install the masternode on a VPS (Virtual Private Server). In order to do so, we will create a VPS on but you can do it on OVH, 1and1 You can find VPS servers from 2.99 per month. Create an account at and log into the admin site to create your first server. Before creating a server, you need to create a set of RSA connection keys, nothing very complicated, these keys are valid for all the servers created on Scaleway. The RSA key set acts as login and password, it also greatly increases the security of your server. Most VPS service providers currently use this type of authentication. 3. Step On OSX and Linux Create the RSA Key Pair Source : Open a terminal Generate a new Key typing the following command ssh-keygen -t rsa Give a name to your Key Enter file in which to save the key (/Users/me/.ssh/id_rsa): otherwise, the default name will be id_rsa Set a passphrase Enter passphrase (empty for no passphrase): this step is not mandatory but highly recommended You should now have two files for your Key (a public key that we will copy on your servers, and a private key that you must keep secret), in our example the two files are located in the /Users/me/.ssh/ directory The public Key is named id_rsa.pub The private Key is named id_rsa The entire key generation looks like this

8 1. ssh-keygen -t rsa Generating public/private rsa key pair. 4. Enter file in which to save the key (/Users/me/.ssh/id_rsa): 5. Enter passphrase (empty for no passphrase): 6. Enter same passphrase again: 7. Your identification has been saved in /Users/me/.ssh/id_rsa. 8. Your public key has been saved in /Users/me/.ssh/id_rsa.pub. 9. The key fingerprint is: :93:cc:c1:5b:76:4f:b6:b9:b4:65:b0:33:8b:f1: Copy your public key content which is required for step 2 1. cat /Users/me/.ssh/id_rsa.pub ssh-rsa AAAAB3NzaC1yc2EAAAADAQABAAABAQD3TsFepMvwNBIjsr3Zr85mj/Aho/tk3220ryzVxgxR44EWz9xe8Yh 4.

OCp+twB9uG+GfFEdheyHcnbxdtkByLzx2GbEnLNZZ99pF9i/cdpcaWCpnnqf/6TNVpFyCWhSfBq8+4OKUHt5vDB On windows Download PuTTYgen Launch PuTTYgen Select SSH-2 RSA and click the Generate button

9 Two keys are generated (a public key that we will be copy on your servers, and a private key that you must keep secret)

10 Fill-in the Key-comment field with a name to help you identify this key pair Click the Save public key button and save it in the folder of your choice Click the Save private key button and save it the same folder Select the public key content. Copy it (below Public key for pasting into OpenSSH authorized_keys file ) into your clipboard which is required for step 2

11

12 Save the content of the public Key on the SSH Keys section You now must save the content of the public Key in the Control Panel. From the Control Panel, open the pull-down menu on your account name and click on Credentials link. In the SSH Keys section paste the content of your public key in the text area and click on New SSH Key button. You are now ready to create and start your first server!

13 4. VPS Creation Select «Create server» Select any of the servers (the cheapest does very well) Select :Ubuntu Xenial (16.04 latest) InformationIt wan work with other distributions but Ubuntu is easy to use. Validate the creation of the server and wait for the server to start (this can take up to 10 minutes) Congratulations, you created a VPS!

14 5. Step Connection to the server Download and install SSH Terminus client: (Compatible with Linux, MacOS and Windows ) Select KeyChain

15 Select Add key

16 Fill in the boxes : Label : Name of your server

17 Passphrase : your password linked to your RSA key Private Key : Your private key previously created Public Key : Your public key previously created

18

19 Save and go back to the menu Select Hosts -> New Host Label : My Server name Address : Server IP Address Username : root Password : RSA key password Select KEY -> and choose the key selected previously. Then select Connect
