Setting up ETH node on Raspberry-Pi

Start Here

Dual Machines

The Raspberry Pi 4B the most advanced Raspberry Pi to date has 8G RAM and performance that falls a bit short of what would required to run a full node, therefore we opt to run the consensus client and the execution clients on separate machines connected via Ethernet

Node Structure

Hardware	Raspberry Pi 4B
OS	ubuntu	C/C++
consensus client	lighthouse	Rust
Execution client	go-ethereum	Go

Machine 1 - lighthouse

Installing a lighthouse client

1. Instructions source
2. Install Rust using rustup：
   • curl --proto '=https' --tlsv1.2 -sSf https://sh.rustup.rs | sh
     • During installation, when prompted, enter 1 for the default installation
     • After Rust installation run cargo version
       • If it cannot be found, run source $HOME/.cargo/env and cargo version should return the version
       • append source $HOME/.cargo/env to ~/.bashrc
3. Install dependencies
   • sudo apt install -y git gcc g++ make cmake pkg-config llvm-dev libclang-dev clang
4. Download source:
   • git clone https://github.com/sigp/lighthouse.git
5. Build from source:
   • cd lighthouse
   • git checkout stable
   • make

Running a lighthouse client

2. Launch a beacon node using Lighthouse

   Use the following command to start a non-staking beacon nod:

   lighthouse bn \
   --network mainnet \
   --execution-endpoint http://localhost:8551 \
   --execution-jwt /secrets/jwt.hex \
   --checkpoint-sync-url https://mainnet.checkpoint.sigp.io \
   --disable-deposit-contract-sync
   

3. Example

lighthouse bn --network sepolia --execution-endpoint http://localhost:8551 --execution-jwt $JWT_SECRET_PATH --checkpoint-sync-url https://sepolia.checkpoint-sync.ethpandaops.io --disable-deposit-contract-sync --http
