I. Run Node​

1. Update​

sudo apt update && sudo apt upgrade -y

2. Package​

sudo apt install curl tar wget clang pkg-config protobuf-compiler libssl-dev jq build-essential protobuf-compiler bsdmainutils git make ncdu gcc git jq chrony liblz4-tool -y

3. Install Docker​

sudo apt-get update
sudo apt-get install \
ca-certificates \
curl \
gnupg
sudo install -m 0755 -d /etc/apt/keyrings
curl -fsSL https://download.docker.com/linux/ubuntu/gpg | sudo gpg --dearmor -o /etc/apt/keyrings/docker.gpg
sudo chmod a+r /etc/apt/keyrings/docker.gpg
echo \
"deb [arch="$(dpkg --print-architecture)" signed-by=/etc/apt/keyrings/docker.gpg] https://download.docker.com/linux/ubuntu \
"$(. /etc/os-release && echo "$VERSION_CODENAME")" stable" | \
sudo tee /etc/apt/sources.list.d/docker.list > /dev/null
sudo apt-get update
sudo apt-get install docker-ce docker-ce-cli containerd.io docker-buildx-plugin docker-compose-plugin

4. SETUP​

git clone --recursive https://github.com/engram-network/tokio-docker.git && cd tokio-docker && chmod +x ./scripts/*.sh && ./scripts/install-docker.sh && ./scripts/install-asdf.sh && mkdir -p execution consensus

5. Create a mnemonic phrase to prepare the deposit data​

eth2-val-tools mnemonic
  • Keep your mnemonic

NOTE: Or use Metamask wallet​

6. Faucet Token Here​

7. Obtain the following parameters in validator-deposit-data.sh​

nano ./scripts/validator-deposit-data.sh
withdrawals-mnemonic: your mnemonic phrase from generate eth2-val-tools.
validators-mnemonic: your mnemonic phrase from generate eth2-val-tools.
from: address that was already funded from the faucet.
privatekey: your privatekey address that has funds from the faucet.
  • Run the following command to generate final the deposit data.
bash ./scripts/validator-deposit-data.sh

8. Generate Public Keys​

./scripts/validator-build.sh
$ ***Using the tool on an offline and secure device is highly recommended to keep your mnemonic safe.***

Please choose your language ['1. العربية', '2. ελληνικά', '3. English', '4. Français', '5. Bahasa melayu', '6. Italiano', '7. 日本語', '8. 한국어', '9. Português do Brasil', '10. român', '11. Türkçe', '12. 简体中文']:  [English]:

Choose English or Press Enter.

$ Please repeat the index to confirm: 

Type "0" since it is the minimum height the data deposit will be created at.

$ Please enter your mnemonic separated by spaces (" "). Note: you only need to enter the first 4 letters of each word if you'd prefer.:

Add your already created mnemonic phrase to be extracted into a public key.

$ Please choose the (mainnet or testnet) network/chain name ['mainnet-soon', 'devnet-1', 'devnet-3', 'devnet-4', 'devnet-5', 'testnet']:  [mainnet-soon]:

Choose testnet and Enter

$ Create a password that secures your validator keystore(s). You will need to re-enter this to decrypt them when you setup your Ethereum validators.:

Create your password with a minimum word of 8 letters/numbers and create a file with the name "password.txt" and save it in the "custom_config_data" folder
after completing creating a password you will be referred like this:

9. Configure Docker Compose docker-compose.yml​

nano docker-compose.yml
identity=username Discord << Replace with your discord username (e.g: avenbreaks. don't add your hastag discord user)
enr-address=0.0.0.0 << Replace with your public IPAddress
graffiti=VNBnode << Replace with your unique name
ethstats=VNBnode:[email protected]

10. Run​

docker compose up -d

You will see the following:

$ docker compose up -d
[+] Running 4/4
 ⠿ Network tokio_default_default                           Created
