Creating a Transaction Validation Node on the MDMCoin Blockchain – LINUX

Installation on LINUX Operating System (Ubuntu)

Minimum device requirements

• RAM Memory – 1024MB / 1GB
• Processor – 2 Core – 2.0 Ghz
• Storage – 10GB

To create a node on the MDMCoin digital currency blockchain and be able to validate transactions/mine and receive rewards in new coins, follow these steps:

1. Download the MDMCoin node software available from the link below and your node configuration file and install it on your device.
   • https://github.com/mdmcoin/mdmcoinnode/releases/
     • ubuntu
       • sudo apt-get install wget
       • mkdir mdmcoin (create folder)
       • cd mdmcoin (access folder)
       • wget https://github.com/mdmcoin/mdmcoinnode/releases/download/mdmcoin-blockchain-v1.0.1/mdm-all-1.0.1.jar (Main file download)
       • wget https://github.com/mdmcoin/mdmcoinnode/releases/download/mdmcoin-blockchain-v1.0.1/mdm.conf (Download the settings file)
2. Install the dependencies and configure the node to your preferences, including firewall and security settings.
   • Settings and installation of dependencies for the UBUNTU
     • sudo apt-get update
     • sudo apt-get install openjdk-8-jre
     • sudo apt-get install screen
     • Release ports 7870 (obligatory) and 7879 (optional) to allow integration with the MDMCOIN network
       • ufw allow 7870 or sudo iptables -I INPUT -p tcp -m tcp – -dport 7870 -j ACCEPT
       • ufw allow 7879 or sudo iptables -I INPUT -p tcp -m tcp – -dport 7879 -j ACCEPT
     • Create your wallet to be integrated into the node for you to receive your rewards through our decentralized web wallet https://wallet.mdmcoin.com/
     • Edit the settings file mdm.conf according to the information requested, use the following link to carry out the process.
       • https://tools.mdmcoin.com/ (Converts keywords from your wallet to BASE58 format)
       • https://nodes.mdmcoin.com/api-docs/index.html#/utils/hashSecure (Converts the password you created for your node-integrated wallet into a Secure Hash)
       • Note: Never place the mdm.conf file in a publicly accessible folder.
3. Start and Synchronize the node with the MDMCOIN blockchain. This may take some time, depending on the speed of your internet connection.
   • To start your node run the following command:
     • screen -d -m -S MDMNODE java -jar /installation directory*/mdmcoin/mdm-all-1.0.1.jar /installation directory*/mdmcoin/mdm.conf
       • * Change according to your installation directory.
     • After executing the command above, wait a few minutes and check if your IP address is already in our list of NODES, it usually takes about 30 minutes.

4. Get a sufficient amount of MDMCOIN through the exchanges where the currency is listed or through the Exchange DEX to become a full node. Currently, it is necessary to have at least 1000 MDMs.
5. Update your mining settings and start mining blocks on the MDMCOIN blockchain.
6. Keep your copy of the blockchain updated and your security settings to be able to generate new blocks and earn new rewards, the greater the balance in your wallet integrated with the node, the greater your chances of receiving rewards.

Remember that being a full node on the blockchain MDMCOIN it requires dedication and responsibility, as you will be helping to maintain the integrity of the network and your node must be active 24 hours a day. But at the same time, you will have the opportunity to earn rewards in MDMs for your participation.
