Running multiple nodes in local
If you managed to setup one node to function properly, then you can proceed and run the local network setup script to have multiple nodes running in local environment.
Running this command you will start a network with 4 nodes in local environment:
1
bash tools/local-network-setup/setup-macos-environment.sh 
Copied!
Running this command you can specify how many nodes you want to start:
1
bash tools/local-network-setup/setup-macos-environment.sh --nodes=10
Copied!
Running nodes on testnet
For a shared development environment, we recommend deploying DKG testnet nodes on the beta testnet - instructions can be found here.
