IPFS: A Simple Guide to the InterPlanetary File System

The internet, as we know it, is built on a centralized infrastructure, with data stored and accessed through designated servers. This centralized model poses several challenges, including censorship, data manipulation, and reliance on intermediaries. Enter IPFS, the InterPlanetary File System, a revolutionary protocol that aims to reshape the internet into a more decentralized, open, and data-secure ecosystem.

What is IPFS?

IPFS is a peer-to-peer protocol that enables the distributed storage and retrieval of data. Unlike the traditional internet where content is stored on central servers, IPFS distributes files across the network, making them accessible from any node. This decentralized approach eliminates the need for intermediaries and ensures that data remains resilient and accessible even if some nodes go offline.

How Does IPFS Work?

IPFS employs a unique content-addressing system that assigns a cryptographic hash to each file, effectively creating a unique identifier. This hash, also known as a CID (Content Identifier), serves as the primary means of locating and retrieving files within the IPFS network. When you want to access a file, you simply provide its CID, and the network will direct you to the nearest node that stores it.

Why Do We Need IPFS?

The need for IPFS stems from the limitations of the current centralized internet architecture. Here are some key reasons why we need IPFS:

  • Decentralization: IPFS eliminates reliance on centralized servers, making it more resistant to censorship and data manipulation.
  • Data Integrity: IPFS’s content-addressing system ensures data integrity by verifying the authenticity of each file before retrieval.
  • Improved Scalability: IPFS can handle growing data volumes by distributing files across the network, preventing bottlenecks and ensuring faster access.
  • Web3 Integration: IPFS is a crucial component of the Web3 ecosystem, enabling the decentralized storage and distribution of content for dApps and blockchain applications.

A Practical Example: Sharing Content on IPFS

Imagine you’re creating a decentralized social media platform using IPFS for storing user-generated content. When a user uploads an image, it gets divided into blocks and distributed across the IPFS network. To share the image, the user simply shares its CID with other users. These users can then retrieve the image from their nearest IPFS node, eliminating the need for centralized servers.

The Complementary Relationship: Blockchain and IPFS

While IPFS and blockchain have different functionalities, they complement each other in addressing the challenges of the current internet. IPFS excels at decentralized storage and efficient data retrieval, while blockchain provides a secure and transparent record-keeping system.

Blockchain provides a secure and transparent record of transactions or data, while IPFS offers a decentralized and efficient storage solution for that data. While blockchain can store small pieces of data, it’s not designed to handle large files like images, videos, or software applications. This is where IPFS steps in.

IPFS tackles the scalability issue of blockchain by offloading the storage of data from the blockchain to a distributed network of nodes. This allows blockchains to focus on their core function of securing and validating transactions, while IPFS handles the efficient storage and retrieval of data.

Improving Blockchains with IPFS

By integrating IPFS with blockchains, we can address several limitations and enhance their overall performance:

  1. Scalability: IPFS offloads data storage from blockchains, enabling them to handle a higher volume of transactions and data without compromising performance or scalability.
  2. Efficiency: IPFS’s content-addressing system enables efficient retrieval of data, reducing the load on blockchain nodes. This leads to faster transaction speeds and improved overall user experience.
  3. Data Security: IPFS’s decentralized nature and content-addressing system ensure data integrity and immutability, mirroring the security aspects of blockchains.
  4. Content Preservation: IPFS’s ability to store and distribute data across a global network ensures the long-term preservation of data, preventing censorship or unauthorized removal.

Examples of IPFS Integration with Blockchains

  • Decentralized File Sharing: IPFS can be used to store and distribute files for decentralized file-sharing platforms, eliminating reliance on centralized intermediaries.
  • Content-Based NFTs: IPFS can store the original digital assets associated with NFTs, ensuring the authenticity and security of these valuable assets.
  • Off-chain Data Storage for Smart Contracts: IPFS can store and manage large amounts of data off-chain, alleviating the storage burden on blockchains and improving transaction speeds.

Projects Built on top of IPFS

Filecoin is a decentralized storage network that is built on top of IPFS. It uses a blockchain to store metadata about files and to reward miners for storing and retrieving data. Miners are nodes on the network that have agreed to store data for other users. They are paid in FIL tokens, which can be used to purchase storage or other services on the network.

Storj is another decentralized storage network that is built on top of IPFS. It uses a different approach to Filecoin, using a proof-of-bandwidth consensus mechanism to ensure the integrity of data. Storj nodes are rewarded in STORJ tokens for storing and retrieving data.

Crust is a decentralized storage network that is built on top of IPFS. It uses a hybrid consensus mechanism that combines aspects of both Proof-of-Work and Proof-of-Stake. Crust nodes are rewarded in CRU tokens for storing and retrieving data.

IPFS and blockchain are not mutually exclusive; rather, they complement each other to address the limitations of the current internet architecture. By combining the strengths of both technologies, we can build a more decentralized, efficient, and secure internet that empowers users and facilitates innovation in various sectors.


IPFS is not just a technology; it’s a paradigm shift in how we think about data storage and sharing on the internet. By decentralizing the web, IPFS empowers users, improves data security, and paves the way for a future where censorship and data manipulation are a thing of the past. As we move towards a more interconnected and data-driven world, IPFS stands as a promising solution for building a more robust, resilient, and open internet.
