We're excited to announce that Filecoin—the world's largest open-source decentralized storage network—is integrating Chainlink's industry-leading decentralized oracle solution. This collaboration establishes bidirectional data transfer between Filecoin and smart contract blockchains like Ethereum. By leveraging Chainlink oracles, developers gain a complete Web3 tech stack:
- On-chain logic via smart contracts
- Off-chain computations through Chainlink oracles
- Decentralized storage with Filecoin
Unlocking Two-Way Smart Contract Capabilities
The Filecoin-Chainlink integration enables groundbreaking use cases:
- Transferring cryptographically verified Filecoin data to external smart contracts
- Triggering automated Filecoin storage from blockchain events
- Enabling NFT insurance claims when content becomes unavailable
- Storing historical blockchain indexes on Filecoin at customizable intervals
- Settling DeFi markets using Filecoin-stored financial datasets
