What is the minimum node network for testnet?

How many nodes and of which type do we need to test the testnet libra network in a private setup?

Thank you in advance

Hi @dimitris and thanks for the question. If you haven’t yet, you might try the docs here: https://developers.libra.org/docs/run-local-network .

Hi, in the libra swarm the node number is 4 and in the docker script is 5. What is the optimal number? Shouldn’t be an odd number?
