EthStorage is a storage rollup built on top of Ethereum. It provides programmable dynamic key-value store based on Ethereum's data availability, in particular EIP-4844 and Danksharding. By periodically submitting storage proof from EthStorage layer 2 network to Ethereum L1, EthStorage aims to reuse Ethereum mainnet security properties while greatly expanding Ethereum storage capacity with much lower cost - targeting Petabytes capacity with 1/1000x storage cost.o 1/100x. Furthermore, the storage layer 2 network is fully permissionless - any one with minimum storage requirement (about 4TB) is able to run as a storage provider. EthStorage is fully integrated with EVM and is compatible with Ethereum development stacks including Solidity, Remix, Hardhat, MetaMask, etc.

EthStorage recently received two grants from the Ethereum Foundation Ecosystem Program for data availability sampling research and layer 2 research.
