Introduction to Taiko

ZK-Rollups scale computation by executing, aggregating, and proving transactions off-chain, and relying on Ethereum for data availability and validity proof verification. The biggest drawback of the currently in-production ZK-Rollups are that they cannot support the generalized computation of the EVM exactly, but instead are mostly application-specific. This breaks compatibility with existing Ethereum L1 smart contracts and dapps, and further, makes it difficult to build new ones that offer the same type of composable, expressive experiences.

Ethereum-equivalent ZK-Rollups, sometimes called ZK-EVMs, are the holy grail of layer-2 scaling solutions in that they do not compromise on security or compatibility. In recent parlance, Taiko aims to be a type-1 ZK-EVM, which prioritizes perfect EVM/Ethereum-equivalence over ZK-proof generation speed.

Taiko consists of three main parts: the ZK-EVM circuits (for proof generation), the L2 rollup node (for managing the rollup chain), and the protocol on L1 (for connecting these two parts together for rollup protocol verification).

More Details

Before start:

Running a node or participate in a test net is at your own risk, there is any guarantee about airdrop and rewards or points.

Part 01: Order And Configure A Cloud Server

You need to rent a cloud server at first , cloud servers have some advantages:

1. High Availability
2. High Scalability
3. Multi Locations
4. Easy to Config
5. Cheap

Note: Hetzner datacenter presents hourly payment option.

Minimum Hardware Requirements

Run a node: CPU: 2vCore, RAM: 2GB, SDD:20GB, OS: Ubuntu 20.04

Run a prover: CPU: 8/16 vCore, RAM: 32GB, SDD:80GB, OS: Ubuntu 20.04

1.If you don’t have a account in a server provider, use this link to sign up and earn €⁠20 for new signing up

2.Click on continue button

3. In the hetzner website click on sign up button

4. Click on REGISTER NOW button

5. Fill the form and continue

6. Do KYC and enjoy it.

7. Click on <+ New project> and add a name project then in new page, click on Add Server

8. Choose your location, OS and hardware based on minimum requirements then write your server name and click on <create and buy> button

Note: An email will be sent about your server like: IP and Password, check your mail box and use the information to connect to server.

Part 02: Connect To Your Server

MacOs: To connect via SSH from this operating system, first open the Terminal window. You can find this tool by going to “Application->Utilities->Terminal”.

Windows: you can use many tools like putty and MobaXterm

1.Download one and lunch the application

2.Use information which has been sent to your email address

3.Copy IP and enter in app and click on Open button

4.Click on “Accept” button , Enter your username and password which sent by Hetzner

Note: To paste any command that you have already copied just right-click where you want to paste the command

5.Enter or paste your password again and type new password and retype it again.

Finally you are on server, now you have permission to write or paste commands.

Recommendation:

I strongly recommend to install the Gaga node next to your node because it consumes a few hardware and you are able to get the most out of your server.

Part 03: Preparation

1.Update & Upgrade Server

Before you get start, need to update and upgrade server

sudo apt update && apt upgrade -y

2. Install Prerequisties

Copy and paste the command below when terminal asks you, enter Y and press ENTER on your keyboard.

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

3.Install Docker

You shoul install the Taiko node by docker, following commands help you to install that.

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

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

Use the following command to set up the repository:

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

Try granting read permission for the Docker public key file before updating the package index:

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

To install the latest version, run:

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

When command prompt asks you, type Y and press ENTER on your keyboard.

To install docker compose:

sudo apt install docker-compose

When command prompt asks you, type Y and press ENTER on your keyboard.

Verify that the Docker Engine installation is successful by running the hello-world image:

sudo docker run hello-world

Check docker compose version:

docker-compose -v

4. Install Screen

Linux Screen provides users an option to open several separate terminal instances within a single terminal window manager. Screen also includes an enhanced command line, giving you extra features and functionality over a standard command line.

More commands about screen .

sudo apt install screen

4.Create a new session by screen .

sudo screen -S <Your Session Name>

Replace <Your Session Name> by name of your choice

sudo screen -S taiko

Part05: Install and Run The Node

1.Download The Node

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

2.Configure The Node

cp .env.sample .env

Edit the configuration file by the command below and copy/paste the saved http/ws keys in last step according to sample. Arrow in image show where you should paste keys.

nano .env

Press Ctrl + X and type y then press ENTER on your keyboard.

3.Enable A Prover (Optional)

Note: If you are going to enable a prover so you need to choose max hardware configuration mentioned in Part01.

Set the following environment variables to enable your node as a prover:

• Set ENABLE_PROVER to true (replacing the default false with true).
• Set L1_PROVER_PRIVATE_KEY to that of your wallet's private key; it will need some balance on Sepolia to prove blocks

Press Ctrl + X and type y then press ENTER on your keyboard.

4.Start The Node

docker compose up

Press Ctrl and A + D to detach screen session.

5.Some Commands (Optional)

Stop a node

This command shuts down the node, but will keep all volumes, so next time you restart the node, it won’t need to synchronize from the genesis again.

docker compose down

Remove a node

These commands will completely remove the node by removing all volumes used by each container:

docker compose down -vrm -f .env

Update a node

Update the simple-taiko-node Docker images:

docker compose pull

View all logs

docker compose logs -f

View the prover image’s logs

docker compose logs -f taiko_client_prover

View the L2 execution engine logs

docker compose logs -f l2_execution_engine

Part06: Complete Tasks

You need perform tasks to complete test net, for now you have run the node.

• 🌉 Use the bridge
• 🔀 Swap tokens
• 🧙 Deploy a contract
• 🛠️ Build a dapp
