Here are the instructions to build the CloudWalk Testnet. This chain is EVM compatible based on Substrate.
I have used Amazon Linux 2 AMI. You will need at least 40GB, 4CPU, 8GB mem to start. Need to go further in transactions benchmarks and see how the nodes will behave at scale.
First install compiler utils on the machine you will generate the node binary for the network. I recommend you use a faster machine to compile (it takes time 20-30 minutes). Then use the binary on the nodes on the network that don't need to be that fast.
sudo yum install -y cmake pkg-config libssl-dev git build-essential clang libclang-dev curl
