Erlang: How to create an Aternity blockchain project with Cowboy and zx

Blockchain tooling can be pretty confusing and tends to suffer a strange situation where the blockchains with the most utility often have the worst tooling and interop libraries. The tooling necessary to connect to the Aeternity blockchain happens to be very easy to get working with Erlang using ZX, however.

In this demo we continue on from the previous video (creating a Cowboy web service using ZX, here https://rumble.com/v2xvn0k ) and extend that to adding the ability to talk with the Aeternity blockchain.
