This document discusses decentralized storage options using Filecoin and IPFS. It introduces core concepts like content addressing, peer-to-peer networks, and storage proofs. It then describes how developers can build applications that leverage these protocols, from storing data using services like Fleek, Estuary, and NFT.Storage, to developing with tools like Powergate. The document encourages learning more about IPFS and Filecoin and offers help from the community.
2. Together, they help us break free from centralized services
while retaining the same luxuries of speed and guarantees.
Filecoin is another protocol
built on top of IPFS, for
storing data long-term via
on-chain deals.
IPFS is a decentralized
web protocol for sharing
data quickly and easily.
3. Content Addressing
CORE CONCEPT #1
Content (or data) is run through a
1-way cryptographic hash function.
The output is a unique content
identifier (CID), acting as a
“fingerprint” for your data.
CIDs give you confidence in the
contents of your data so you can
easily deduplicate it, verify that it’s
not corrupted, or fetch it from anyone
in a p2p network.
5. Storage Proofs
CORE CONCEPT #3
Filecoin Network is
designed for extremely
large-scale storage.
Deals are recorded
on-chain, including CIDs
which can be used for
verification.
6. Compatible with
IPFS & Web3
Use IPFS as a
building block to
share all the benefits
of content
addressing and
CIDs. Integrate with
Web3 networks like
NEAR and Hedera.
Verifiable, via
cryptographic
proofs
How can you prove
that you’re really
storing my data and
keeping your
promises? How can I
enforce this in a
decentralized
network?
A massive,
decentralized
network
8 exabytes across
the globe from
hundreds of storage
providers. Governed
by consensus,
instead of any single
corporation.
Filecoin is storage designed for Web3
from the ground up

12. IPFS ❤ Filecoin
CORE CONCEPTS
IPFS for fast,
flexible retrieval
(gateways, local
nodes, browsers,
oh my!).
Filecoin for
persistence and
verifiability.
14. DESIGNED FOR
● Fast, modern, censorship-proof websites
and webapps on the open web
● Works with most modern frameworks
(Docker, Gatsby, React, Webflow, Hugo,
Next, Jekyll, etc.)
HOW IT WORKS
● Connect your Github repository
● Add build settings
● Deploy your site to IPFS
● Backed up to Filecoin
USAGE
● Github Actions
● CLI
● GraphQL API

15. We highly recommend
choosing a storage helper.
They simplify deals and workflows,
making it fast and easy to build.
Storing & Retrieving Data
Store to both IPFS and
Filecoin with a single call.
IPFS for fast, flexible retrieval
(gateways, local nodes, browsers,
oh my!). Filecoin for persistence and
verifiability.
Simplify dealmaking.
Finding providers, negotiating
prices, waiting for confirmations,
verifying storage — storage helpers
handle it all for you.
16. DESIGNED FOR
● Ideal for building desktop apps
● Not ideal for web apps
HOW IT WORKS
● Combines IPFS, Textile Buckets, &
Textile Powergate into one background
service
● Runs on users’ desktops
● Can be bundled with desktop apps
USAGE
● gPRC API
● JS client

17. DESIGNED FOR
● General Filecoin & IPFS storage
● Seamless dealmaking and verification
HOW IT WORKS
● Data is immediately uploaded to a hosted Estuary
(IPFS+Filecoin) node
● Automatically stores with 6 providers around the world
USAGE
● HTTP API
● CURL
● Web interface
Estuary

18. DESIGNED FOR
● NFT developers who want free decentralized
storage
HOW IT WORKS
● Upload your data, get back an IPFS hash of
the content (a CID) that can be used in
on-chain NFT data as a pointer.
○ Storage + Retrieval is free!
○ Get properly formatted metadata back!
● Fetch it back via IPFS (pinned redundantly >3x)
● Backed up to Filecoin (stored redundantly >5x)
USAGE
● JS client library
● HTTP API
● Configured as remote pinning service in IPFS

19. DESIGNED FOR
● Developers who want powerful ways to
connect & extend Libp2p, IPFS, and
Filecoin
● Bridges to NEAR and (coming soon) Eth,
Polygon, & others.
HOW IT WORKS
● Docker container wrapped around an
IPFS node + Filecoin node
● Stage, store, and retrieve data
● Default configs for miner selection
