Overview¶
DataHaven is a decentralized storage and retrieval network designed for apps that need verifiable, production-scale data storage. DataHaven connects users and storage providers through an on-chain system that guarantees data availability and integrity.
The pages in this section explain how users, providers, and on-chain proofs work together to provide a secure, interoperable, trust-minimized storage layer.
Store Off-Chain, Verify On-Chain¶
DataHaven separates file storage from on-chain verification, giving you the benefits of performant, cost-effective storage and retrieval without sacrificing reliable data provenance. Storage providers store user data off-chain and create cryptographic on-chain commitments for verification.
See Data Flow and Lifecycle for a step-by-step look at how data moves through the storage, replication, verification, and retrieval process.
Verify Proofs for Data Integrity¶
File and directory state is summarized as Merkle roots. Those roots are anchored on-chain, giving you a tamper-evident history and a way to verify storage proofs independent of any single provider. Periodic proof challenges with potential slashing penalties ensure continued data storage over time.
Connect Across Ecosystems¶
Snowbridge acts as a trustless bridge between Ethereum and Substrate-based chains like DataHaven, enabling on-chain, verifiable, bidirectional movement of tokens and messages using familiar EVM tooling.
Secure By Design¶
The network is built as an autonomous verifiable service (AVS) that leverages Ethereum restaking via EigenLayer to secure the protocol's core checks and incentives. Authentication is web3-native, using SIWE and short-lived JWTs, so users sign once and interact with providers securely.
Future Development¶
You can currently onboard with the StorageHub SDK to create buckets and upload, download, share, and verify files. EVM smart contract compatibility and broader programmability are under development for future releases.
