Decentralized Storage

Storage is an integral part of modern computer systems, and the same is true for distributed and decentralized systems like a blockchain. When interacting with the Polkadot ecosystem, it will be helpful if you familiarize yourself with the current Web3 approach towards decentralized storage.

DCS (Decentralized Cloud Storage)

The key attribute that characterizes centralized cloud storage is the location of data.

In decentralized cloud storage, the key attribute becomes the data itself instead of the data's location.

This can be viewed as the shift from the centralized location-centric storage approach to the decentralized content-centric approach.

IPFS (Interplanetary File System)

IPFS is a peer-to-peer distributed file system that seeks to connect all computing devices with the same system of files, by utilizing features such as content-addressing, content-signing, and enhanced security methods through encryption. IPFS aims to address the current hurdles of the HTTP-based Internet.

Brief comparison of IPFS & HTTP:

network: peer-to-peer model (decentralized)network: client-server model (centralized)
requests: use a cryptographic hash of that datarequests: use the address on which data is hosted
accessibility: data is distributed to multiple nodes and can be accessed at any time. Bandwidth is high: nearest peer can serve the dataaccessibility: data can only be accessed if the server is live and there are no interruptions in transmission. Bandwidth is limited: clients send requests to the same server

Crust Storage

Crust Network provides a Web3.0 decentralized storage network for the Metaverse. It is designed to realize core values of decentralization, privacy, and assurance. Crust supports multiple storage-layer protocols such as IPFS, and exposes instant accessible on-chain storage functions to users. Crustʼs technical stack is also capable of supporting data manipulating and computing.

Crust provides a native cross-chain communication pallet based on XCMP, called xStorage.

The protocol also supports most smart contract platforms, including Ethereum, with its cross-chain dStorage solution.

Filebase is the first S3-compatible object storage platform that allows you to store data in a secure, redundant, and performant manner across multiple decentralized storage networks.

Filebase offers a geo-redundant IPFS pinning service that allows you to pin files to IPFS across multiple diverse geographic locations. All files uploaded to IPFS through Filebase are automatically pinned to the Filebase infrastructure with 3x replication across the globe. This ensures that your data is globally available and redundant at all times.

Filebase acts as an easy on-ramp to IPFS and decentralized storage by offering a user-friendly web console dashboard, making drag-and-dropping files onto Web3 simple and easy. Filebase also provides an S3-compatible API for widespread integrations and configurations in current workflows.

Using Polkadot-JS Files (IPFS) module

Polkadot-JS UI includes a decentralized storage module that allows Substrate-based chain users to upload their files to an IPFS W3Auth Gateway and use the IPFS W3Auth Pinning Service to pin their files on Crust Network.

Start by uploading a single file or folder:


Choose a Gateway:


Sign the message:


You should be able to view the file info, as follows:

file info

As well as the file status:

file statue


The whole files module is decentralized, so your file directory is only cached in browser. The file directory info will not be visible if you switch to a new browser or clear the browser cache. The storage module allows you to export file directory info from the current browser and import it to the new browser.
