The InterPlanetary File System (IPFS) is a decentralized storage and distribution system that aims to overcome the limitations of traditional centralized web technologies. In recent years, there has been growing interest in using IPFS to create decentralized video hosting platforms, such as D.tube, IPFS.video, and PeerTube. In this article, we will review the current achievements and challenges faced by developers in creating such platforms, and propose breakthrough technical solutions that can significantly improve stability, performance, and user experience.
IPFS is a protocol and network that enable the creation of decentralized applications. Unlike traditional web technologies, where data is stored on centralized servers, IPFS uses a peer-to-peer network where each node can store and distribute files. Files in IPFS are identified by unique cryptographic hashes (CIDs), ensuring their integrity and immutability.
-
D.tube
- Description: D.tube is a decentralized platform for uploading and viewing videos, based on blockchain and IPFS.
- Current Implementation: When using D.tube, users connect to an IPFS gateway, which acts as a bridge between traditional web browsers and the IPFS network. This allows users to view videos as if they were stored on a centralized server.
- Problems: The main issue is the instability of the IPFS network, which can lead to delays and interruptions in video streaming. Additionally, using an IPFS gateway can slow down page loading.
-
IPFS.video
- Description: IPFS.video is an experimental project that uses the JavaScript library js-ipfs to directly connect to the IPFS network and stream video through the MediaSource API.
- Current Implementation: The project fills the MediaSource API with chunks from the IPFS network, allowing videos to be played directly from decentralized storage.
- Problems: The main issue is synchronizing incoming Byte Arrays with the Video Buffer, which can lead to Browser Memory Overload. Developers are working on improving this function to ensure More Stable and Efficient Video Playback.
-
PeerTube
- Description: PeerTube is a decentralized Platform for Uploading and Viewing Videos, Based on Free and Open-Source Software. Although PeerTube does not use IPFS by default, the community is actively discussing integrating IPFS for storage and delivery of videos.
- Current Implementation: PeerTube uses a peer-to-peer network for distributing videos, reducing the load on centralized servers. However, full integration with IPFS requires significant development.
- Problems: The main issue is the complexity of integrating IPFS with the existing PeerTube architecture. Security and scalability issues also need to be addressed.

¶ Solutions for Caching and Data Replication in Decentralized Video Hosting on IPFS
Caching and data replication are key aspects for improving the stability and performance of decentralized video hosting platforms based on IPFS. These methods can speed up video file loading, reduce network load, and increase data availability. In this section, we will detail how to effectively implement caching and data replication.
Goal: Speed up the loading of frequently requested video files and reduce network load.
Mechanism:
- Local Storage: When a user loads a video file, it is also stored on the local user node.
- Fast Access: On subsequent requests for the same file, the browser first checks the local cache before sending a network request.
1.2.1. Using IPFS-Companion
Description: IPFS-Companion is a browser extension that allows connecting to the IPFS network and caching data on the local node.
Steps:
- Install IPFS-Companion: Users install the IPFS-Companion extension in their browser.
- Configure Connection: The extension automatically connects to the local IPFS node, which can be run using
js-ipfs or go-ipfs.
- Cache Data: When a user views a video, IPFS-Companion caches the data on the local node.
Example Code:
import { IPFSCompanion } from 'ipfs-companion';
const ipfsCompanion = new IPFSCompanion({
gateway: 'http://localhost:8080',
api: 'http://localhost:5001'
});
ipfsCompanion.on('ready', () => {
console.log('IPFS-Companion is ready');
});
ipfsCompanion.on('pin', (cid) => {
console.log(`Pinned ${cid}`);
});
ipfsCompanion.on('unpin', (cid) => {
console.log(`Unpinned ${cid}`);
});
1.2.2. Automatic Caching of Frequently Requested Files
Description: Develop algorithms that automatically cache frequently requested files on local user nodes.
Steps:

function trackRequest(cid) {
if (requestStats.has(cid)) {
requestStats.set(cid, requestStats.get(cid) + 1);
} else {
requestStats.set(cid, 1);
}
}
function cachePopularFiles() {
const popularFiles = Array.from(requestStats.entries())
.sort((a, b) => b[1] - a[1])
.slice(0, 10) // Cache 10 most popular files
.map(([cid, _]) => cid);
popularFiles.forEach(cid => {
ipfs.files.get(cid, (err, files) => {
if (err) {
console.error(`Error caching ${cid}: ${err}`);
return;
}
files.forEach(file => {
ipfs.files.write(`/cache/${file.path}`, file.content, { create: true }, (err) => {
if (err) {
console.error(`Error writing to cache: ${err}`);
} else {
console.log(`Cached ${file.path}`);
}
});
});
});
});
}

async function uploadAndPinFile(filePath) {
const file = fs.createReadStream(filePath);
const response = await pinata.pinFileToIPFS(file);
console.log(`Pinned file with CID: ${response.IpfsHash}`);
}
uploadAndPinFile('path/to/your/video.mp4');

.slice(0, 10) // Replicate 10 most popular files
.map(([cid, _]) => cid);
for (const cid of popularFiles) {
await node.pin.add(cid);
console.log(`Replicated ${cid}`);
}
}
replicatePopularFiles();

});
const pinata = createClient('YOUR_PINATA_API_KEY', 'YOUR_PINATA_SECRET_API_KEY');
const requestStats = new Map();
function trackRequest(cid) {
if (requestStats.has(cid)) {
requestStats.set(cid, requestStats.get(cid) + 1);
} else {
requestStats.set(cid, 1);
}
}
async function manageCacheAndReplication() {
const popularFiles = Array.from(requestStats.entries())

if (err) {
console.error(`Error writing to cache: ${err}`);
} else {
console.log(`Cached ${file.path}`);
}
});
});
});
}
// Replication on multiple nodes
for (const cid of popularFiles) {
await node.pin.add(cid);
console.log(`Replicated ${cid}`);
}
// Upload to Pinning Service
for (const cid of popularFiles) {
const file = await node.cat(cid);
const response = await pinata.pinFileToIPFS(file);
console.log(`Pinned file with CID: ${response.IpfsHash}`);
}
}
// Example Usage
trackRequest('Qm...'); // Record request
manageCacheAndReplication(); // Manage caching and replication
