Setup Lotus Devnet using a GUI

As an alternative to the CLI you can use Pond, a graphical testbed for lotus. It can be used to spin up nodes, connect them in a given topology, start them mining, and observe how they function over time.

Build:

$ make pond

Run:

$ ./pond run
Listening on http://127.0.0.1:2222

Now go to http://127.0.0.1:2222.

Thing to try

• The Spawn Node button starts a new lotus Node in a new draggable window.
• Click [Spawn Storage Miner] to start mining (make sure the Node's wallet has funds).
• Click on [Client] to open the Node's client interface and propose a deal with an existing Miner. If successful you'll see a payment channel open up with that Miner.

Don't leave Pond unattended for long periods of time (10h+), the web-ui tends to eventually consume all the available RAM.

Troubleshooting

• Turn it off and on - Start at the top
• rm -rf ~/.lotus ~/.lotusstorage/
• Verify you have the correct versions of dependencies
• If stuck on a bad fork, try lotus chain sethead --genesis
• If that didn't help, open a new issue, ask in the Community forum or reach out via Community chat.
