# Tessellation The [Tessellation project](https://github.com/Constellation-Labs/tessellation) is the core protocol implementation of the Constellation Network. It defines the logic and infrastructure that powers the Hypergraph—the global Layer 0 responsible for consensus, snapshot processing, and coordination across all metagraphs. Tessellation also includes the foundational components needed to build, run, and connect metagraphs to the network. As the lowest-level implementation of the network, Tessellation acts as the foundation for higher-level tooling, including the [Euclid SDK](/metagraph-development/introduction.md), which simplifies metagraph development. While most developers will interact primarily with Euclid, Tessellation provides the underlying services, protocols, and consensus mechanics that enable scalable, decentralized applications to operate securely on the Constellation Network. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question. Perform an HTTP GET request on the current page URL with the `ask` query parameter: ``` GET https://docs.constellationnetwork.io/network-fundamentals/development-stack/tessellation.md?ask= ``` The question should be specific, self-contained, and written in natural language. The response will contain a direct answer to the question and relevant excerpts and sources from the documentation. Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
