## What it is
DataHaven is an EVM-compatible Substrate blockchain that provides verifiable decentralized storage, built on StorageHub and secured by EigenLayer restaking. Storage providers store data off-chain while Merkle-tree commitments are anchored on-chain for tamper-evident verification, with cross-chain bridging to Ethereum via Snowbridge.

## Use cases
- store AI training data with verifiable integrity proofs
- run a decentralized storage provider network with on-chain slashing
- deploy EVM smart contracts on a storage-focused chain
- bridge tokens and messages trustlessly between Ethereum and DataHaven
- secure a validator set using EigenLayer restaking
- store machine learning models with tamper-evident commitments

## When to choose
- you need verifiable, production-scale decentralized storage for Web3 or AI workloads
- you want Ethereum-compatible tooling with EigenLayer-secured validation
- you need trustless cross-chain bridging with Ethereum

## When to avoid
- you need simple centralized object storage like S3
- you want a general-purpose smart contract chain without storage focus
- you are not comfortable operating or interacting with blockchain infrastructure

## Facets
- artifact type: application
- maturity: active
- function: blockchain, file-system, cryptography, security, database
- domain: blockchain, artificial-intelligence, privacy, microservices
- platform: rust, cross-platform
- tags: substrate, eigenlayer-avs, decentralized-storage, evm, storage-providers, web3, merkle-proofs, snowbridge, cryptocurrency, linux, macos
