What is IPFS – InterPlanetary File System?

IPFS (InterPlanetary File System) is a decentralized protocol and peer-to-peer network for storing and sharing files. It was created by Juan Benet in 2015 and aims to replace traditional centralized systems such as HTTP (HyperText Transfer Protocol) that are used today to access content on the Internet.

How does IPFS work?

IPFS works on the basis of content-based addressing, which means that content is identified by its hash code (unique digital fingerprint) instead of being addressed by location (servers). This approach has several key advantages:

  • Content-based addressing: Each file uploaded to IPFS has a unique hash that remains the same unless the content changes. This means that the file address is directly derived from its content.
  • Distributed storage: Files are stored on multiple nodes in the network, eliminating the need for centralized servers. If a file is accessible on multiple nodes, IPFS fetches it from the nearest source.
  • Efficient sharing: The system uses a technology similar to BitTorrent, where files are broken into smaller pieces and distributed across the network. This allows for fast and efficient downloads.

Main advantages of IPFS

  • Censorship resistance: Since content is distributed, it is very difficult (if not impossible) to remove or block it.
  • Reduced server load: Thanks to the peer-to-peer architecture, content can be fetched from multiple users at the same time.
  • Permanent links to content: Hash addresses ensure that links to content are consistent and do not change.
  • Better scalability: Decentralization allows the network to expand without the need to invest in centralized infrastructure.
  • Privacy and security: Thanks to content-based addressing and distribution, the system is robust against attacks and provides greater security than traditional HTTP.

IPFS Usage Examples

  • Data Storage for Decentralized Applications (dApps): Many blockchain networks, such as Ethereum or Filecoin, use IPFS to store large amounts of data that the blockchain cannot directly store.
  • Decentralized Website Hosting: Websites can be stored on IPFS and accessed via special URLs.
  • Data Archiving: IPFS is suitable for long-term data storage because the content is always available if a node has it.
  • Distributed Media: Music, videos, and other media can be shared without intermediaries, reducing costs and improving availability.

IPFS and Blockchain

IPFS is often used in combination with blockchain. The blockchain is used to record ownership or transaction data, while IPFS stores the data itself. This approach allows for efficient solutions to the limited storage space on blockchains.

Example: NFTs (non-fungible tokens) often use IPFS to store metadata or images associated with tokens, while the ownership itself is recorded on the blockchain.

IPFS offers a revolutionary way to store and share data that is decentralized, secure, and efficient. Its potential ranges from improving the internet to completely transforming the way we process data in the digital world.
