If you are excited about the potential of the Filecoin protocol and decentralized storage network to build game-changing applications, you’ve come to the right place.

Why develop on Filecoin?

Filecoin combines the benefits of storage on IPFS (a peer-to-peer content-addressing system) with blockchain-powered storage guarantees. The network offers robust and resilient distributed storage at massively lower cost compared to current centralized alternatives.

Developers choose Filecoin because it:

  • is the world’s largest distributed storage network, without centralized servers or authority
  • offers on-chain proofs to verify and authenticate data
  • is highly compatible with IPFS and content addressing
  • is the only decentralized storage network with petabyte-scale capacity
  • stores data at extremely low cost (and keeps it that way for the long term)

An ecosystem of developer tools offers flexible, powerful choices for integrating Filecoin storage into your application or workflow.

Filecoin and IPFS

How do Filecoin and IPFS work together? They are complementary protocols for storing and sharing data in the distributed web. Both systems are open-source and share many building blocks, including content addressing (CIDs) and network protocols (libp2p).

IPFS does not include built-in mechanisms to incentivize the storage of data for other people. To persist IPFS data, you must either run your own IPFS node or pay a provider.

This is where Filecoin comes in. Filecoin adds an incentive layer to IPFS. Storage deals are recorded on-chain, and providers must submit proofs of storage to the network over time. Payments, penalties, and block rewards are all enforced by the decentralized protocol.

Filecoin and IPFS are designed as separate layers to give developers more choice and modularity, but many tools are available for combining their benefits. This diagram illustrates how these tools (often called storage helpers) provide developer-friendly APIs for storing on IPFS, Filecoin, or both.

Get started

Let’s get building. Choose one of the following APIs. These are all storage helpers, or tools and services that abstract Filecoin’s robust dealmaking processes into simple, streamlined API calls.

Filecoin and smart contracts

You can improve speed and reduce gas fees by storing smart contract data on Filecoin. With Filecoin, the data itself is stored off-chain, but is used to generate verifiable CIDs and storage proofs that are recorded on the Filecoin chain and can be included in your smart contracts. This design pairs well with multiple smart contract networks such as Ethereum, Polygon, Avalanche, Solana, and more. Your smart contract only needs to include the compact content ids.
