- [Access Control](https://protocol.crunchdao.com/core-concepts/access-control.md): The Secure Model Protocol that authenticates communication between Coordinators and Model Runners.
- [Crunch Lifecycle](https://protocol.crunchdao.com/core-concepts/crunch-lifecycle.md): The full lifecycle of a Crunch — from creation and funding through competition, payouts, and closure.
- [Crunch Nodes](https://protocol.crunchdao.com/core-concepts/crunch-nodes.md): The services you build and host to run your competition — data ingestion, model orchestration, scoring, and reporting.
- [Crunch Protocol](https://protocol.crunchdao.com/core-concepts/crunch-protocol.md): The on-chain and off-chain architecture that connects Coordinators with ML engineers to solve prediction challenges.
- [Data Security and Model Protection](https://protocol.crunchdao.com/core-concepts/data-security-and-model-protection.md): How the Crunch Protocol protects submitted models and Coordinator data using TEE, MPC, and other privacy-preserving techniques.
- [Model Nodes](https://protocol.crunchdao.com/core-concepts/model-nodes.md): Managed infrastructure that executes participant models securely and makes them callable over the network.
- [Model Orchestrator](https://protocol.crunchdao.com/core-concepts/model-orchestrator.md): Manages the lifecycle of participant model containers — deploying, monitoring, and keeping them reachable.
- [Model Runner and Client](https://protocol.crunchdao.com/core-concepts/model-runner-and-client.md): The gRPC server that makes each model callable over the network, and the Python client library Coordinators use to call them.
- [Tournament Hub](https://protocol.crunchdao.com/core-concepts/tournament-hub.md): The web platform where Crunchers discover, join, and compete in your Crunch.
- [Challenge package example](https://protocol.crunchdao.com/getting-started/challenge-package-example.md): How to structure the participant-facing package that ML engineers use to join your competition.
- [Crunch Node Example](https://protocol.crunchdao.com/getting-started/crunch-node-example.md): How the default Crunch Node works — workers, data feeds, prediction collection, scoring, and reporting.
- [Define your own Crunch](https://protocol.crunchdao.com/getting-started/define-your-own-crunch.md): Customize the prediction task, scoring function, and challenge package to build your own competition.
- [Local environment setup](https://protocol.crunchdao.com/getting-started/local-environment-setup.md): Launch your first competition on the Crunch Protocol by running a complete local development environment.
- [Mainnet Deployment](https://protocol.crunchdao.com/getting-started/mainnet-deployment.md): Deploy your Crunch to mainnet with production-grade security.
- [Testnet Deployment](https://protocol.crunchdao.com/getting-started/testnet-deployment.md): Deploy your Crunch to the Solana devnet for end-to-end testing.
- [Wallet & CLI Setup](https://protocol.crunchdao.com/getting-started/wallet-and-cli-setup.md): Create a Solana wallet, register as a Coordinator, and prepare for deployment.
- [Use cases](https://protocol.crunchdao.com/overview/use-cases.md): How institutions use the Crunch Protocol across finance, science, and crypto.
- [What is the Crunch Protocol?](https://protocol.crunchdao.com/overview/what-is-the-crunch-protocol.md): The Crunch Protocol connects domain experts with a global network of ML engineers to solve real-world prediction challenges.
