what's Lighthouse?
Lighthouse is a decentralized storage protocol built on Filecoin, enabling permanent, secure, and verifiable data storage for Web3 applications. It allows developers to upload, pin, and retrieve files using content identifiers (CIDs), with support for streaming from buffers or readers, and multi-chain deployment across networks like Base, Polygon, and Solana. The protocol emphasizes privacy through encrypted storage and zero vendor lock-in, making it suitable for AI data pipelines, token launches, and autonomous infrastructure that require auditable, reproducible datasets. Key features include a developer-friendly Go SDK for programmatic file management, deal tracking, and metadata handling. Lighthouse integrates seamlessly into the emerging data economy, supporting dApps powered by AI agents and Internet Capital Markets (ICM). By anchoring data permanently on decentralized networks, it ensures data ownership remains with users, fostering open and transparent systems without reliance on centralized servers.
Lighthouse partnered with Marlin Protocol for decentralized frontend storage on IPFS/Filecoin.
