Run a Taiko Node

You can establish your node by either configuring it on a personal computer or by utilizing a Virtual Private Server (VPS), which is well-suited for managing websites, applications, or other internet-based services, including nodes.

For my setup, I selected Contabo, a well-regarded provider of VPS rentals. Opting for a plan with at least 100 GB of storage is advisable to ensure sufficient space for long-term node operation.

My suggestion would be to go for the Cloud VPS M option. https://contabo.com/en/

1. Select Payment Term
2. Region — Germany
3. Storage Type -400 GB SSD
4. Image — Go to Apps & Panels > Docker

5. Log in & Password for your Server

6. Object Storage — Default

7. Networking — Default

8. Add-Ons — Default

After finalizing your payment, you’ll get an email verifying your purchase. Hold tight for a follow-up email, which will provide details about your VPS, encompassing your access credentials.

You’ll need to download and use Putty, a tool that enables you to securely connect to your VPS and utilize its functionalities. Download it here https://www.putty.org/

Enter the VPS IP Address then Click OPEN

Login : root

Password: (is the one you set earlier on Contabo VPS)

Install Necessary components

1. Install essential components

Before setting up the node it is important to update your VPS

sudo apt-get update && sudo apt-get upgrade -y

Install Essential Codes

sudo apt install pkg-config curl git-all build-essential libssl-dev libclang-dev ufw

2. Check if Docker is up-to-date

docker version

If docker is not installed, run the following command:

sudo apt-get install ca-certificates curl gnupg lsb-release

Now add Docker’s official GPG key:

sudo mkdir -p /etc/apt/keyrings
curl -fsSL https://download.docker.com/linux/ubuntu/gpg | sudo gpg --dearmor -o /etc/apt/keyrings/docker.gpg

proceed. . . .. We Are to set up Repository: (just copy and paste)

echo \
  "deb [arch=$(dpkg --print-architecture) signed-by=/etc/apt/keyrings/docker.gpg] https://download.docker.com/linux/ubuntu \
  $(lsb_release -cs) stable" | sudo tee /etc/apt/sources.list.d/docker.list > /dev/null

Let’s grant Docker file permission just in case, before updating the package index

sudo chmod a+r /etc/apt/keyrings/docker.gpg
sudo apt-get update

after granting, updated index, Install latest version of docker

sudo apt-get install docker-ce docker-ce-cli containerd.io docker-compose-plugin

Reply with Y and press ENTER Now install Docker compose :

sudo apt install docker-compose

Lets verify the ENGINE INSTALLATION is successful by running the hello-world

sudo docker run hello-world

You should get this.

Now check Docker compose version :

docker-compose -v

Let’s Install SCREEN

sudo apt install screen

Create new screen session

sudo screen -S taiko

NODE INSTALLATION

1. Download Node

git clone https://github.com/taikoxyz/simple-taiko-node.git
cd simple-taiko-node

2. Node Configuration

cp .env.sample .env

3. Edit Configuration

nano .env

Sample .env file with Proposer
(edit using arrow keys)

Sample:
< L1_ENDPOINT_HTTP=https://rpc.sepolia.org/
< L1_ENDPOINT_WS=wss://ethereum-sepolia.blockpi.network/v1/ws/56f9eaZZZZZZZZZZZZZZZZZZZZZZZZZZ
< ENABLE_PROVER=false
< L1_PROVER_PRIVATE_KEY=f3982a81dc1372d731b6YYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYY
< PROVE_BLOCK_TX_GAS_LIMIT=2500000
< MIN_ACCEPTABLE_PROOF_FEE=10
< ENABLE_PROPOSER=true
< L1_PROPOSER_PRIVATE_KEY=9125dbab06f560546688b7a5f1551cdd36bbXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX
< L2_SUGGESTED_FEE_RECIPIENT=0xE2fa3e074b9A804cb082DE23dMMMMMMMMMMMMMMMMMMMMMMMMMMMMMMMMMMMMMMM
< PROPOSE_BLOCK_TX_GAS_TIP_CAP=20000000000
< BLOCK_PROPOSAL_FEE=10
< PROVER_ENDPOINTS=

4. Start the Node

docker compose up

5. Check Logs

docker compose logs -f

6. Wait until current blocks are synced.

View Grafana Dashboard to see status. (Enter URL, *Change localhost to your VPS IP address)

open http://localhost:3001/d/L2ExecutionEngine/l2-execution-engine-overview

You can verify that your node is syncing by checking that the chain head on the dashboard (see above) is increasing. Once the chain head matches what’s on the block explorer, you are fully synced.
