According to ChainCatcher, the Layer2 solution EthStorage, which provides programmable dynamic storage, announced on October 14 that its mainnet has officially launched.
EthStorage brings PB-level, verifiable storage capabilities to Ethereum, making long-term, on-chain data preservation feasible and cost-controllable. This launch marks a key breakthrough in Ethereum's modular roadmap: after having the computation layer (L2 Rollups) and consensus layer (Ethereum L1), a decentralized storage layer has now been added, unlocking Web2-level scale and Web3-level security for the next generation of Web3 applications.
