Section 1.1: Introduction to IPFS

One such system that is rapidly gaining traction is the InterPlanetary File System (IPFS).

IPFS is a network and protocol designed to enhance the speed, security, and openness of the web. This decentralized, global file storage system enables users to host content and share it with others without relying on a central server.

Being an open-source initiative spearheaded by the CollabDAO Foundation, IPFS is built on the BitTorrent protocol and utilizes a distributed hash table for file storage. This structure allows for more efficient and secure distribution of files compared to traditional web protocols.

The first video provides an insightful tutorial on building a distributed web using IPFS, showcasing its capabilities and advantages.

Section 1.2: Advantages of IPFS

IPFS presents several key benefits over conventional web protocols:

• Speed: Files are delivered more swiftly, thanks to a network of distributed servers.
• Security: It enhances file delivery security by employing a distributed hash table for verification.
• Openness: Being open-source and decentralized, IPFS fosters a more transparent digital environment.

Section 2.1: Key Technologies Behind IPFS

IPFS employs various technologies, including:

• Distributed Hash Table (DHT): This decentralized data store enables data distribution among network nodes, ensuring load distribution and redundancy.
• Merkle DAG: This data structure combines elements of Merkle Trees and Directed Acyclic Graphs, facilitating trustless systems where data integrity can be verified without needing the entire dataset.
• Self-Certifying File System (SCFS): SCFS allows users to certify file systems securely and conveniently using public key cryptography.

Section 2.2: The Decentralized Nature of IPFS

IPFS promotes decentralization by allowing distributed application creation through its peer-to-peer file system. This architecture makes it challenging for central authorities to censor content or track users, as data is widely dispersed across multiple nodes.

The benefits of decentralization include:

• Resilience Against Censorship: Content removal or censorship becomes significantly more difficult.
• Enhanced User Privacy: Data spread across numerous nodes minimizes tracking risks.
• Network Stability: The network remains operational even if individual nodes fail.

Section 2.3: Utilizing IPFS for NFT Data Storage

NFT data can be efficiently stored on IPFS in various ways. One method involves creating a hash of the NFT data and storing it directly on the network. Alternatively, users can create dedicated folders for each NFT, organizing the data systematically.

Here's a sample code illustrating how to store NFT data on IPFS:

var NFTData = "This is an NFT data";

var NFTHash = sha256(NFTData);

var IPFSHash = "QmW3c4NtkfX3J4VEVSVZZcPtYmtWmgYh1WEZUCaUKVE2";

var fs = require("fs");

var ipfs = require("ipfs-node");

fs.createFolder("NFTData", function(err) {

if (err) {

console.log("Error creating NFTData folder: " + err);

} else {

ipfs.add(IPFSHash, function(err, result) {

if (err) {

console.log("Error adding NFTData hash to IPFS: " + err);

} else {

console.log("Hash added to IPFS: " + result);

}

});

}

});
