2021-07-23 Example console app demo

[leighmcculloch]

Here's video demo of a rudimentary payment channel working on a test network between @acharb and I.

It is the examples/console app using the sdk/state package at e84216d.

This is only demoing the happy path because the console example is only a good actor at the moment. There are integration tests that test some bad actor paths, and are in the process of writing more bad actor scenarios.

There’s still lots of gaps. At the moment the SDK is a state machine that produces and verifies transactions/agreements, and makes sure to some degree that you don’t sign something you shouldn’t. We have a growing list of TODOs to make the state machine more robust and cover more edge cases as well as adding other helpful things to the SDK. A user of the SDK still needs to figure out their own networking and communications, none of that is currently handled by the SDK.
