Core Technology
Overview
DataHaven is a decentralized storage solution built on a Proof-of-Stake, layer 1 blockchain secured by EigenLayer’s re-staking protocol. It offers an EVM-compatible environment with fast finality and integrated data storage. The network consists of “storage providers” managing off-chain data storage and an EVM blockchain coordinating storage requests, tracking ownership, and verifying data. The blockchain secures file storage by managing and verifying proofs from storage providers.
Substrate Framework
DataHaven is built on Substrate, a modular framework in Rust with a rich library of reusable components (pallets). Substrate’s extensibility and active development community enable easy customization. By leveraging Substrate, DataHaven gains access to battle-tested pallets used in networks like Moonbeam and Polkadot, offering features like cross-chain interactions, trustless bridging, governance, and Proof-of-Stake with fast finality. This flexibility, efficiency, and interoperability make Substrate ideal for web3 innovation.
DataHaven provides an unshakable foundation for the next wave of digital transformation.
Integration with Ethereum
DataHaven is fully EVM compatible, supporting popular wallets and tools and providing a familiar environment for EVM developers. Unlike other web3 storage solutions that operate separately from computation blockchains, causing inefficiencies, DataHaven enables seamless interactions between smart contracts and stored data.
With DataHaven, dApps can interact with the storage layer, managing large datasets, file uploads, access permissions, and storage proofs for data integrity verification. For example, an NFT collection could store digital assets and verify authenticity onchain. DataHaven also supports secure, collaborative workflows for projects requiring shared access to critical documents, such as Real-World Asset (RWA) initiatives, ensuring decentralized accessibility and control.
Secured by EigenLayer’s re-staking protocol, DataHaven relies on Ethereum for economic security, unlike standalone storage blockchains that have weaker security. This ensures multi-chain applications are backed by Ethereum’s stake and offers robust protection for assets and data.
Additional Features
Interoperability
DataHaven is EVM-compatible and includes a native bridge to Ethereum, plus support for General Message Passing (GMP) protocols for secure cross-chain storage interactions.
Ease-of-Use
Specialized pre-compiles enhance user and developer experiences, such as a “CallPermit” pre-compile for gasless transactions and a “Batch” pre-compile to reduce transaction approvals and costs.
Onchain Governance
Powered by Substrate’s OpenGov pallets, DataHaven enables forkless upgrades and parameter changes via community voting. It also supports decentralized handling of legal requests, ensuring compliance while preserving decentralization.
Economic Model
$HAVE System Token
DataHaven’s economic model is centered around $HAVE, a system token native to the network. This token is integral to the network’s operation and value accrual and will serve several key functions, as discussed below.
Staking to Secure DataHaven
Although the re-staking of Ethereum will form the bedrock of DataHaven’s crypto-economic security, the EigenLayer protocol allows for other assets to be staked/re-staked to help secure an AVS. Holders of $HAVE will be able to delegate stake to operators in order to participate in securing DataHaven and earn rewards. (It should be noted that Moonbeam’s native token GLMR and/or GLMR LSTs will also be able to be staked/re-staked in a similar manner.)
Payment for Execution
As with a typical EVM environment, the cost of gas will be denominated in the system token. Therefore, the $HAVE token will be the gas token for the network used to pay for computational resources and transaction fees. All transactions and smart contract executions will require a fee, which will be paid in $HAVE. A dynamic fee mechanism will be used to prevent spam and ensure efficient use of network resources. Priority fees will be included in rewards to operators (validators) while the base fee will be split into a portion directed to treasury and a portion to be burned, configurable via governance.

Storage Fees and Incentives
Storage fees may be paid using the $HAVE token. Conversely, payments to storage network operators providing storage services may be denominated in the $HAVE token. However, a future goal of the project is to have predictable storage costs and payments to operators, in dollar terms, per GB per unit of time. In order for storage providers to participate in the network and earn fees for storing data, they will be required to hold collateral denominated in $HAVE, which may be slashed if they lose user data, ensuring a commitment to data preservation.
Governance
The $HAVE token is central to the network’s governance, empowering stakeholders to shape decisions. Token holders can vote on proposals and referendums, with voting power based on the amount and lock period of tokens. Token holders govern data storage fees, council composition, and fund allocation through onchain voting. Additionally, they can delegate voting power for decentralized decision-making.
