IPFS is a peer-to-peer distributed file system designed to connect all computing devices through a content-addressed, versioned, and decentralized system. It combines a distributed hash table, an incentivized block exchange, and a self-certifying namespace, offering high throughput and robust data distribution. IPFS is inspired by systems like BitTorrent, Git, and SFS, and aims to address limitations of HTTP and traditional file systems. It uses a Merkle DAG for content addressing, enabling efficient data storage, versioning, and distribution. IPFS supports content-addressed hyperlinks, allowing for a permanent web where data is accessible and verifiable. The system is designed to be decentralized, with no single point of failure, and nodes do not need to trust each other. IPFS includes a block exchange protocol (BitSwap) that incentivizes data sharing and ensures efficient distribution. It also features a self-certifying naming system (IPNS) for mutable state, allowing users to publish and retrieve content with verified identities. IPFS is intended to evolve the web into a more robust, decentralized infrastructure, supporting a wide range of applications, including versioned file systems, encrypted data sharing, and distributed databases. The system is built on principles of content addressing, versioning, and decentralized peer-to-peer networking, aiming to provide a more efficient and reliable alternative to traditional web infrastructure.IPFS is a peer-to-peer distributed file system designed to connect all computing devices through a content-addressed, versioned, and decentralized system.
