🟢Chainbase

Chainbase is the world’s largest omnichain data network designed to integrate all blockchain data into a unified ecosystem, providing an open and transparent data interoperability layer for the AI era.

It has designed a novel dual-chain technology architecture that bridges the programmability and composability of crypto data, which supports high throughput, low latency, and eventual determinism, as well as higher cybersecurity through a dual staking model.

1. Update and install packages

sudo apt update & sudo apt upgrade -y

2. Install Docker & Docker compose

curl -fsSL https://download.docker.com/linux/ubuntu/gpg | sudo gpg --dearmor -o /usr/share/keyrings/docker-archive-keyring.gpg
echo "deb [arch=$(dpkg --print-architecture) signed-by=/usr/share/keyrings/docker-archive-keyring.gpg] https://download.docker.com/linux/ubuntu $(lsb_release -cs) 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 version

VER=$(curl -s https://api.github.com/repos/docker/compose/releases/latest | grep tag_name | cut -d '"' -f 4)
curl -L "https://github.com/docker/compose/releases/download/"$VER"/docker-compose-$(uname -s)-$(uname -m)" -o /usr/local/bin/docker-compose

chmod +x /usr/local/bin/docker-compose
docker-compose --version

3. Install Go

cd $HOME && \
ver="1.22.0" && \
wget "https://golang.org/dl/go$ver.linux-amd64.tar.gz" && \
sudo rm -rf /usr/local/go && \
sudo tar -C /usr/local -xzf "go$ver.linux-amd64.tar.gz" && \
rm "go$ver.linux-amd64.tar.gz" && \
echo "export PATH=$PATH:/usr/local/go/bin:$HOME/go/bin" >> ~/.bash_profile && \
source ~/.bash_profile && \
go version

4. Install EigenLayer CLI

curl -sSfL https://raw.githubusercontent.com/layr-labs/eigenlayer-cli/master/scripts/install.sh | sh -s
export PATH=$PATH:~/bin
eigenlayer --version

5. Clone Chainbase AVS repo

git clone https://github.com/chainbase-labs/chainbase-avs-setup
cd chainbase-avs-setup/holesky

6. Create/Import Eigenlayer wallet

eigenlayer operator keys create --key-type ecdsa "wallet_name"

Set password & save your private key:

# Import an old key (optional)

eigenlayer operator keys import --key-type ecdsa "wallet_name" PRIVATEKEY

7. Fund your Eigen wallet

You’ll need at least 1 Holesky ETH to cover the gas cost of the operator registration. Make sure to send at least 1 ETH to your Eigenlayer operator’s address Link faucet Holesky ETH: https://cloud.google.com/application/web3/faucet/ethereum/holesky https://holesky-faucet.pk910.de/

8. Config & register operator

eigenlayer operator config create

• Enter your operator address: your Eigenlayer address

• Enter your earnings address (default to your operator address): `your Eigenlayer address`

• Enter your ETH rpc url: https://ethereum-holesky-rpc.publicnode.com

• Select your network: `holesky`

• Select your signer type: `local_keystore`

• Enter your ecdsa key path: /root/.eigenlayer/operator_keys/joseph-test.ecdsa.key.json

9. Edit metadata.json

nano /root/chainbase-avs-setup/holesky/metadata.json

Sample metadata.json:

{
  "name": "JosephTran",
  "website": "https://www.josephtran.xyz",
  "description": "Blockchain enthusiast and validator",
  "logo": "https://raw.githubusercontent.com/Josephtran102/chainbase/main/Jlogo.png",
  "twitter": "https://x.com/josephtran102"
}

Logo support .png only and less than 1Mb

• Create a Public repositry in github

• Upload logo.png and metadata.jsonthere.

The logo raw link must set correctly as format:https: /raw.githubusercontent.com/Josephtran102/chainbase/main/Jlogo.png

Sample public repo: https://github.com/Josephtran102/chainbase

10. Edit operator.yaml

nano /root/chainbase-avs-setup/holesky/operator.yaml

Set URL metadatar with raw file link:

• metadata_url: https://raw.githubusercontent.com/Josephtran102/chainbase/main/metadata.json

11. Register Eigenlayer Operator (holesky)

eigenlayer operator register operator.yaml

Check status:

eigenlayer operator status operator.yaml

12. Config Chainbase AVS

a. Create .env file

nano .env

Input content and edit your info:
