Understand the project
Practical overview
When it fits
Use Datahaven when an application needs decentralized storage with cryptographic verification of stored and retrieved data, rather than storage that relies only on an off-chain provider.
Who it is for
- Developers building AI data infrastructure
- Teams storing or retrieving machine-learning models
- Web3 application developers needing decentralized storage
- Builders requiring verification of off-chain data through on-chain commitments
Documented uses
- Store AI training datasets through decentralized storage providers
- Store and retrieve machine-learning models
- Provide replicated storage for Web3 applications
- Verify retrieved off-chain data against on-chain cryptographic commitments
- Use Ethereum-compatible smart contracts with the network
Before you choose
Requirements & limits
The official repository is public and identifies the project as GPL-3.0 licensed. The documented technical platforms include Linux, CLI, server and self-hosted environments.
- Data is stored off-chain while commitments are anchored on-chain.
- Main Storage Providers serve data and coordinate storage; Backup Storage Providers replicate it.
- Merkle-tree hashing and proof challenges support data-integrity verification.
- Frontier provides EVM compatibility for Ethereum-oriented smart contract tooling.
- The repository includes node, runtime, smart-contract, test and Kubernetes deployment components.
Check current requirements in the official documentation. Source-based guidance does not mean OpenViST has run or independently tested this project.
