Mining MaxxChain - Ubuntu

These instructions are for Ubuntu users, will work for version 18,20,22. Note that there are similarity in setting up a mining node and a regular node but some minor change and precautions needs to be

Setup a user

Create a user ubuntu and provide sudo permission

useradd -m ubuntu
passwd ubuntu

Make him sudo

usermod -aG sudo ubuntu

Try not to use root to install. Use ubuntu user to continue with steps below.

Default Ports

Allow ports 30303 on firewall with the following command

🚨 Security Alert 🚨

Do not open port (8545)

ufw allow 30303 # allows peers connect to you but not required if you don't want to publish your node address
ufw deny 8545 # do this just to be sure the port is not left open

Switch to the ubuntu user we just created above

su ubuntu
cd ~

Install Go Lang if you have not already done so:

🚨 Make sure you are in /home/ubuntu folder 🚨

wget https://storage.googleapis.com/golang/go1.19.linux-amd64.tar.gz
tar -xvf go1.19.linux-amd64.tar.gz
sudo rm -fr /usr/local/go
sudo mv go /usr/local
export GOROOT=/usr/local/go
export PATH=$GOPATH/bin:$GOROOT/bin:$PATH

Installing MaxxChain Node

Clone Repo and build geth

cd ~
git clone https://github.com/maxxchain/go-ethereum
cd go-ethereum/
sudo apt-get update && sudo apt-get dist-upgrade -y
sudo apt-get install build-essential make git screen unzip curl nginx pkg-config nmap xterm screen tcl -y
make geth

Add geth to path (optional)

export PATH=/root/go-ethereum/build/bin:$PATH"

Setup genesis Block

git clone https://github.com/maxxchain/genesis-block && cd genesis-block

If you want to mine MaxxChain Testnet use 👇

geth --datadir data init /path/to/genesis-block/testnet.json

If you will be mining MaxxChain Mainnet use 👇

geth --datadir data init /path/to/genesis-block/mainnet.json

Create account for mining rewards

geth account new

Enter a strong password and save the generated address, which will be used to receive mining rewards.

Start the geth client with the --mine flag to enable mining and --miner.etherbase flag to set the mining reward address. Replace <your_reward_address> with the address generated in the previous step:

geth --networkid 10201 --datadir data --port 30303 --syncmode full --mine --miner.etherbase=<your_reward_address>

Geth will start mining using your local machine's resources. You can also add the --miner.threads flag followed by a number to specify the number of CPU threads to use for mining. For example, --miner.threads=4 would use 4 threads.

🚨 Important note 🚨

Make sure to replace the --networkid 10201 with the appropiate chain id depending if you want to run the MaxxChain mainnet or the testnet.

Connect to geth console to add seed peers

git clone https://github.com/maxxchain/bootnodes && cd bootnodes

• Give permission to the executable bash file

sudo chmod 755 mainnet-init.sh
sudo chmod 755 testnet-init.sh

Run the command to install community defined MaxxChain peers onto your geth

If you are running MaxxChain mainnet

./mainnet-init.sh

If you are running MaxxChain testnet

./testnet-init.sh
