Agora-el is an execution client that has an EVM.
Agora-el was forked from Ethereum's execution client, ethereum/go-ethereum version 1.10.23.
We implemented the function of issuing commons budget in Agora-el.

Agora-cl is a consensus client with a focus on usability, security, and reliability.
Agora-cl was forked from Ethereum's consensus client, prysmaticlabs/prysm version 3.1.1.
We modified the block confirmation rewards in Agora-cl.

Install Docker Engine

To run the Agora node, you must first install the Docker Engine.
See here for instructions on how to install the Docker Engine
