# PDP

PDP is a cryptographic protocol that verifies storage providers hold client data. It is a core component of Filecoin Onchain Cloud.

PDP is a challenge-response protocol that lets applications verify storage providers still hold specific data without re-downloading it. It is a core component of [Filecoin Onchain Cloud (FOC)](/build-on-filecoin/filecoin-onchain-cloud.md), where it powers the verification layer for FWSS and Filecoin Pay.

## Run a PDP provider

FOC lets you sell storage from your own hardware, and everything you need runs on a single machine. The Curio-PDP Docker stack packages Forest (chain), Yugabyte (database), and Curio-PDP (the storage node with a web dashboard). One command brings it up; a web guide on `http://127.0.0.1:4701` handles wallet, disks, domain, and FOC registration. Downloads aside, setup takes about five minutes.

```bash
git clone https://github.com/filecoin-project/curio.git

# Mainnet
docker compose -f curio/docker/skiff/docker-compose.yaml up -d

# Calibration test network (free test funds)
cd curio/docker/skiff
docker compose -f docker-compose.yaml -f docker-compose.calibnet.yaml up -d
```

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation by asking a question.

Perform an HTTP GET request on the following URL with the `ask` and `goal` query parameters:

```
GET https://docs.filecoin.io/provide-storage/pdp.md?ask=<question>&goal=<user_goal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is what the user is ultimately trying to achieve, the reason they need the answer. Sharing it helps GitBook give you a better, more relevant answer. A goal is most helpful when it describes the outcome the user wants rather than restating the question. For example, with `ask=how do I create an API token`, a goal like `automate deployments from our CI pipeline` lets GitBook tailor the answer to that use case.

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.
