Demo

Our standard demo setup for demonstrating the Hydra Head protocol.

The demo consists of:

• a cluster of three Hydra nodes, directly connected to each other, each having access to one of three Hydra credentials alice, bob, or carol;
• a single Cardano node producing blocks used as a local devnet;
• a Prometheus server to gather metrics;
• ad-hoc terminal user interface clients to interact with the individual Hydra nodes;

📄️ With Docker

We'll be using Docker and compose to get the demo running, so make sure you have them in scope or, jump right away to Running The Demo: Without Docker if you feel like doing it the hard way.

📄️ Without Docker

Running the demo without Docker containers, but with plain executables and scripts.

Disclaimer

This video demonstrates a basic terminal user interface for the sake of example. Behind the scene, the terminal client relies on a WebSocket API provided by the Hydra nodes which is what applications will likely be using. Said differently, this is one example of possible application (and to be frank, not a very interesting one!)
