IPFS - Interplanetary File System

4 min read

The InterPlanetary File System (IPFS) is a peer-to-peer (P2P), decentralized file storage and sharing system designed to make the web faster, safer, and more open. It was created as a response to the centralized nature of the traditional web, which relies on servers controlled by a few large entities.

Objectives of IPFS

  1. Decentralization: Remove reliance on central servers and reduce the power of big tech gatekeepers.
  2. Resilience: Enable a web that remains online even if parts of it are attacked or disconnected.
  3. Efficiency: Avoid redundant data transfers and optimize content delivery.
  4. Permanence: Make digital information permanent and verifiable, useful for archiving and preserving knowledge.
  5. Censorship resistance: Create infrastructure that’s hard to censor or take down.

How IPFS Works

  • Content Addressing:
    • Instead of URLs that point to where content is (like https://example.com/file), IPFS uses hashes that point to what the content is.
    • Each file is given a unique cryptographic hash (a content identifier or CID). If the content changes, so does the hash.
  • Distributed File Storage:
    • Files are split into small chunks. Each chunk is stored on different nodes (computers) in the network.
    • When you request a file, IPFS searches the network for the nodes that have the required chunks.
  • Peer-to-Peer Discovery:
    • Nodes talk to each other directly, forming a distributed network.
    • A Distributed Hash Table (DHT) helps nodes find each other and locate content.
  • Versioning & Pinning:
    • IPFS supports version control, similar to Git.
    • Users can “pin” content to keep it stored persistently on their nodes.

People and Organizations Behind IPFS

  • Creator: Juan Benet, a computer scientist and entrepreneur, founded IPFS in 2015.

  • Primary Organization: Protocol Labs, the research and development lab behind IPFS. They also developed:

    • Filecoin: A cryptocurrency-based storage marketplace built on top of IPFS.

    • Libp2p: A modular P2P networking stack used by IPFS and other projects.

  • Ecosystem Partners:

    • Mozilla, Netflix, OpenBazaar (defunct), and many academic institutions have experimented with or adopted IPFS tech.

    • Projects like the Internet Archive and The Web3 Foundation support similar decentralized web principles.

Political and Philosophical Directions

IPFS is aligned with the broader Web3 and decentralization movement, which values:

  • Autonomy and self-governance over centralized corporate control.
  • Open-source collaboration over proprietary lock-in.
  • Censorship resistance in support of free speech and open access.
  • Digital sovereignty—users own their data and identity.

It often attracts supporters of:

  • Techno-libertarianism (emphasis on freedom from centralized control),
  • Digital human rights advocacy, and
  • Decentralized governance initiatives.

Use Cases

Journalism & Censorship Resistance

Use Case: Preserving truth in hostile environments

  • Example: News publications in authoritarian countries
    • Independent journalists use IPFS to publish articles that can’t be taken down, even if their websites are blocked or seized.
    • By sharing the IPFS content hash, anyone can access the story from anywhere — no domain required.
  • Tools used: IPFS + ENS (Ethereum Name Service) or IPNS (InterPlanetary Naming System)

NFT Storage

Use Case: Making NFTs actually decentralized

  • Problem: Most NFTs just link to media hosted on traditional servers. If that server goes down, the NFT “disappears.”

  • Solution: Store the NFT’s image or metadata on IPFS, so the NFT points to a permanent, decentralized file.

  • Popular platforms:

    • Pinata, NFT.Storage (by Protocol Labs), and Fleek help NFT projects pin their files on IPFS.

  • Example: Cryptographic art platforms like Zora, Foundation, and OpenSea use IPFS under the hood.

Archiving and Cultural Preservation

Use Case: Keeping important digital records alive

  • Internet Archive has explored using IPFS to back up huge collections.

  • Open-access science journals, community zines, and even Wikipedia snapshots have been preserved via IPFS.

  • This prevents the “link rot” that often breaks references and digital footnotes over time.

Decentralized Web Apps (dApps)

Use Case: Hosting apps that don’t rely on centralized cloud services

  • dApps use IPFS to host their front-end code, making them immutable and censorship-resistant.

  • Often combined with:

    • Ethereum or Solana for smart contracts

    • Filecoin or Arweave for storage incentives

    • Fleek and web3.storage for streamlined deployment

  • Examples:

    • Voting platforms (e.g. Snapshot)

    • DAO dashboards

    • Anonymous publishing tools

Activism and Human Rights

Use Case: Safe distribution of sensitive info

  • Activist groups and whistleblowers use IPFS to share documents and videos that might otherwise be taken down.

  • Example: During the Hong Kong protests and similar movements, IPFS was used to archive content that was being rapidly deleted from social platforms.
