The Tournament Hub is the public-facing platform where Crunchers discover competitions, submit models, and track their performance. Once your Crunch Node is running and your Crunch is registered on-chain, the Hub is where participants find you.

​
How it connects to your Crunch

When a Cruncher uploads a model to your Crunch — either through the Hub or the Crunch CLI — the model is deployed to a Model Node and becomes callable by your Crunch Node via the Model Runner Client. The data your Crunch Node sends to the report worker API powers the Hub’s leaderboard, metrics charts, and performance dashboards for your competition.
The Hub becomes relevant after you have designed your Crunch and registered it on-chain. During local development, the Coordinator Platform at http://localhost:3000 serves the same role.

​

​
For Coordinators

As a Coordinator, you control what appears on the Hub for your Crunch by configuring:
  • Leaderboard columns — which metrics to display and how to rank models
  • Metrics widgets — charts and visualizations for participant performance
  • Competition metadata — description, rules, prize pool, and links to your challenge package
These are configured through the Coordinator Platform and your report worker API.
