EthStorage is a modular and decentralized Layer 2 storage solution built on top of Ethereum. It offers programmable dynamic key-value storage powered by Ethereum's data availability, particularly EIP-4844 and Danksharding. By periodically submitting storage proofs from the EthStorage Layer 2 network to Ethereum L1, EthStorage aims to reuse Ethereum mainnet security properties while significantly expanding Ethereum's storage capacity at a much lower cost. It targets petabyte-scale capacity with storage costs reduced by a factor of 1/1000. Additionally, the storage Layer 2 network is fully permissionless, allowing anyone with a minimum storage requirement (about 4TB) to operate as a storage provider. EthStorage is fully integrated with the Ethereum Virtual Machine (EVM) and is compatible with Ethereum development stacks, including Solidity, Remix, Hardhat, and MetaMask. (
