Lodestar on Ubuntu
Posted on 2022-02-10 in crypto
In order to create a robust decentralized blockchain, Ethereum 2 will require a diverse set of clients. Prysm and Lighthouse are currently dominating. I will install Lodestar, a Eth2 implementation written in Typescript maintained by ChainSafe Systems via npm
Install Ubuntu
Install the latest Ubuntu LTS release (currently Ubuntu 20.04.3 LTS Focal Fossa)
Ubuntu desktop and server are the same but offer different default packages. I started with server because we don't need a desktop environment, office suite, web browser...
We will need make. This is achieved with:
sudo apt install build-essential
Lodestar requirements
The nodejs package in Ubuntu repositories is crusty. Install nvm (node version manager) Check their Github page for the latest version of the install script. Update your environment variables after running the script.
curl -o- https://raw.githubusercontent.com/nvm-sh/nvm/v0.39.1/install.sh | bash
source .bashrc
Now install node Long Term Support and yarn
nvm install --lts
nvm use --lts
npm install -g yarn
Install lodestar
npm install -g @chainsafe/lodestar-cli
Run
lodestar --help
If you get a -bash: /home/USER/.nvm/versions/node/v16.14.0/bin/lodestar: Permission denied error, run:
chmod +x ~/.nvm/versions/node/v16.14.0/lib/node_modules/@chainsafe/lodestar-cli/lib/index.js
