What Is Filecoin? | Decentralized Storage Explained Home Learn Store Data Provide Storage Developers Network Community Blog EN 中文 The authenticity layer of a more resilient internet Filecoin is the world's largest decentralized storage network. By leveraging cryptographic verification and global redundancy, Filecoin safeguards humanity's information, keeping it free from centralized control. Explore documentation What is Filecoin? A decentralized alternative to today's storage solutions. Filecoin is a decentralized alternative to today's storage solutions, offering a better foundation for humanity's information. A handful of corporations currently control most of the world's data. This centralized model creates gatekeepers, introduces single points of failure, and reduces transparency. Filecoin offers a fundamentally different approach to data storage by distributing data across a decentralized, global network, secured by cryptographic proofs. Loading Video... What is Filecoin used for? From archival backups to Web3 and AI apps, Filecoin offers decentralized, secure, and verifiable storage at scale. Web3 apps & AI datasets Powering the data layer for NFTs, video streaming, AI training datasets, and dApps. Backups & archival storage Secure, long-term storage for mission-critical data. Cultural archives Preserving humanity's knowledge and records for the long term. Scientific datasets Enabling resilient access to genomics, public research, and large-scale scientific data. Explore real-world case studies How data moves through Filecoin Users and storage providers interact through onchain deals. The blockchain records and monitors these deals, using publicly verifiable proofs to ensure the data is correctly stored and accessible. Decentralized by design The Filecoin network provides decentralized storage secured by cryptographic proofs and economic incentives, transforming data storage into open, verifiable infrastructure. Onchain proof of storage Filecoin uses two proofs to ensure data integrity: Proof of Replication verifies a unique copy of data exists, and Proof of Spacetime confirms it remains stored over time. Powered by incentives The Filecoin token (FIL) powers the network's economy. Clients pay in FIL to store data, while providers earn FIL by offering reliable services. Providers must lock FIL as collateral and earn rewards by submitting valid proofs. Verifiable retrieval With Filecoin Onchain Cloud , retrieval performance is provable onchain, turning speed and reliability into measurable, verifiable metrics. Built for scale The network's infrastructure is designed to support exabyte-scale datasets and long-term preservation with built-in global distribution and redundancy. Start storing on Filecoin Learn about the Filecoin protocol For technically curious people who want to go deeper into how Filecoin actually works. Content addressing Files are retrieved via content identifiers (CIDs) instead of location-based URLs prone to deterioration. See how content addressing works Storage & retrieval deals Clients make programmable deals with independent storage providers in a global marketplace. Learn about storage deals Proofs & verification Providers must cryptographically prove they are storing data. Understand Filecoin proofs Token Incentives (FIL) The native token aligns economic incentives and rewards useful storage over time. Explore FIL token economics Filecoin Virtual Machine (FVM) The smart-contract layer that lets developers build logic, automation, and apps on top of Filecoin storage. Discover the FVM Filecoin Plus (Fil+) An incentive system that aims to increase the amount of useful data stored on the Filecoin network. Read about Filecoin Plus Explore documentation Be a part of a more resilient internet Filecoin is more than storage; it's an innovative, open ecosystem built to preserve humanity's information.
