How To Add A Node To An Existing Network

You can quickly spin up additional nodes to your network as it grows and designate the new node as either a watcher or a validator. The mechanics of this are simple:

From the dashboard of an existing network, click on <Add node>

There is a quick add:  which lets you spin up a node automatically configured based on the main network, or a custom settings node where you can set up different cloud servers and locations.

You can choose whether the new node is a validator or a watcher node.

What's a Validator or a Watcher?

Watchers

Watcher nodes monitor the network, submit transactions, and store the current version of the ledger

They do not participate in consensus.

Validators

If a node is set up to participate in consensus, it is called a validator.

Validators serve a purpose somewhat similar to miners - they agree on sets of transactions every several seconds via consensus and update the global ledger.

The more validator nodes in the network, the better.
