Setting up a Node

Learn how to start the mining process by setting up a node

MaxxChain Node Setup

These instructions are for Ubuntu users, will work for version 18,20,22

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, 8545 on firewall with the following command

🚨 Security Alert 🚨

If you are mining do not open port (8545)

ufw allow 30303
ufw allow 8545

Switch to the ubuntu user we just created above

su ubuntu
cd ~

Install Go Lang:

🚨 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 run MaxxChain Testnet node use 👇

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

If you will be running a MaxxChain Mainnet node use 👇

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

Start Geth and Node Sync

geth --networkid 10201 --datadir data --port 30303 --http --http.port 8545 --http.addr 0.0.0.0 --http.api personal,eth,net --http.corsdomain '*' --syncmode full

Chain Id's for MaxxxChain Mainnet and Testnet

• Mainnet = 10201

• Testnet = 10203

🚨 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

Congratulations you have your geth full node up and running.

If you wish to support the MaxxChain community by dedicating your node to the public to further allow other nodes connect with your node you can use the instruction below

Start Geth Node Using

geth --networkid 10201 --datadir data --port 30303 --http --http.port 8545 --http.addr 0.0.0.0 --http.api personal,eth,net --http.corsdomain '*' --syncmode full --nat extip:your_server_public_address

Where your_server_public_address is the ip address of your server that is publicly available

Make sure you are in the go-ethereum directory then run this command to get your node peer url

geth attach --exec admin.nodeInfo.enode data/geth.ipc

If that is successful you will see a long string starting with enode:// and ending with your server_ip:30303, share this string with the

MaxxChain team/Dev team and it will be included in our community peers list on our github https://github.com/maxxchain/bootnodes/blob/main/mainnet-nodes.txt

Thank you for reading, if you have any issues setting this up you can ask more questions on the telegram and we will come to your rescue.
