Deploy a Ethereum Node in your macbook
Prerequisite Hardware 💻
To run a blockchain node, your laptop needs to meet certain hardware requirements:
- Processor: A multi-core processor like an Intel i5 or Apple M1/M2 is sufficient for lightweight nodes.
- Memory (RAM): At least 8GB, though 16GB is ideal for better performance.
- Storage: Blockchain nodes require significant storage. For example:
- Bitcoin: ~500GB+
- Ethereum: ~1TB+ Use an external SSD if your internal storage is limited.
- Internet Connection: A stable connection with no data caps is crucial, as nodes regularly sync data.
Run a Blockchain Node on Your MacBook 🛠️
Here’s a step-by-step guide to running an Ethereum node (as an example):
- Install Homebrew
Homebrew is a package manager for macOS. Open your terminal and install it:
bash
/bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/HEAD/install.sh)"- Install Ethereum client
bash
brew install erigon- Start the ethereum node
The following command will launch the ethereum blockchain node and will save the data in data directory.
bash
erigon --internalcl --prune=hrtc --datadir=data --http.addr="0.0.0.0" --http.api=eth,web3,net,debug,trace,txpool- Interact with the node when it is ready
bash
curl -X POST http://localhost:8545 -H "Content-Type: application/json" \
-d '{"jsonrpc":"2.0","method":"eth_blockNumber","params":[],"id":1}'Et voila, that's it! Welcome to the world of decentralized finance!
