Overview

These guides are for operators who want to supply storage to Filecoin Onchain Cloud, rather than build applications on top of it. You run a Proof of Data Possession (PDP) node, register it with the Filecoin Warm Storage Service (FWSS), and earn USDFC as clients store data with you.

A storage provider node is a Curio deployment backed by a Lotus chain node and a YugabyteDB database. PDP is the proof mechanism: your node periodically proves to the PDPVerifier contract that it still holds each client’s data in a retrievable state. Once registered, your node appears in the provider directory and the SDK can select it for client uploads.

Terminology

In the Filecoin Onchain Cloud context, storage provider, PDP provider, and FWSS provider refer to the same role: an operator running a PDP-enabled node registered with Warm Storage. These guides use PDP node for the running stack and storage provider for the operator.

Guides

Install & Run a PDP Node

Deploy the full Lotus, YugabyteDB, and Curio stack and register with Warm Storage. Covers both Calibration and Mainnet. Start →

Withdraw from Filecoin Pay

Withdraw your available USDFC balance from Filecoin Pay and swap it to FIL, using either filpay-cli or Foundry. Read →

Advanced

Production hardening: an Nginx reverse proxy for TLS termination and LXD containers for isolating nodes. Explore →

Before You Start

You need a Linux host that meets the PDP hardware requirements and a public HTTPS endpoint.

Resource	Minimum
RAM	32 GiB
CPU	8 cores
Fast storage (NVMe/SSD)	1 TiB
Long-term storage (HDD)	10 TiB
GPU	Not required
Connectivity	Public HTTPS endpoint (domain) with HTTP/2

The install guide is written for Ubuntu 22.04. On other distributions, adapt the package installation steps to your platform.
