# Layer 1: MPC-CMP (Cryptographic)

Multi-Party Computation (MPC) is the bedrock. It splits secret information across multiple parties to perform a calculation without ever revealing the inputs.

* **Protocol Agnostic:** Unlike Multi-Sig, which is chain-specific, MPC works on ECDSA and EdDSA curves—covering 99% of all blockchains.
* **The CMP Breakthrough:** Keystone’s proprietary **MPC-CMP** algorithm is 8x faster than industry-standard MPC (GG18). It requires fewer rounds of communication to generate a signature, enabling cold-storage security at hot-wallet speeds.
* **Disaster Recovery:** Key shares are distributed across Tier-1 cloud providers and on-premise data centers. Even if a data center is vaporized, your assets remain recoverable.

# 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.keystntoken.xyz/4-security-matrix/layer-1-mpc-cmp-cryptographic.md?ask=<question>
```

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.
