關於EthStorage
EthStorage is a storage-oriented Layer 2 on Ethereum that gives on-chain applications low-cost, large-capacity storage readable and writable by key. It addresses a structural constraint of Ethereum itself: the execution layer keeps only a state root, and calldata and blob data are discarded by nodes after a few weeks, so content that must stay readable, such as NFT metadata, game saves and on-chain front ends, ends up on centralized servers or content-addressed pinning layers. EthStorage splits data into chunks held in key-value stores run by storage nodes, which stake tokens and periodically submit proofs of data possession showing they hold the segments they claim. Sequencing and execution still rely on Ethereum, while storage proofs are verified by contracts before incentives settle.
Use cases center on data that must be verifiable on-chain and readable long term: dynamic NFT attributes, fully on-chain game state and archival of rollup history. Rather than one-time payment for permanent storage, it uses a rent model renewed over time, and its key-value interface resembles a database, letting contracts query a specific key instead of retrieving a whole file by content hash.
EthStorage，一個針對可程式動態儲存的Layer 2解決方案，於2025年10月14日啟動主網，透過在運算層與共識層之外新增去中心化儲存層，標誌著以太坊模組化路線圖的重要里程碑。2024年3月，該專案啟動公開測試網，吸引超過170個節點提交逾490個儲存證明，展現社群運作儲存網路的可行性。測試網活動持續至2024年中，展示了去中心化前端與後端在dApp中的應用，證明了永久網路部署的實用性。一項重要的技術里程碑是2025年8月完成的公開可信設定儀式，共有全球287位貢獻者參與，確保了支撐協議證明系統的zk-SNARK電路安全。此外，2024年12月，EthStorage完成了由Salus進行的全面安全審計，強化了其基礎設施的穩健性。這些發展共同確立了EthStorage作為長期資料可用性的基礎組件，能以約以太坊L1成本0.1%實現具成本效益的永久儲存，並支援如全鏈上AI代理等進階應用場景。
On 8 January 2026 EthStorage published its annual report confirming that mainnet Alpha was live on Ethereum, with a Layer 2 storage network preserving data after blobs expire, scaling programmable key-value storage to petabytes at roughly three orders of magnitude below onchain cost. On 23 June the team detailed a client-side verification scheme built with Colibri that lets front ends verify data provenance in the browser without running a full node.
Through 2026 EthStorage continued work on the web3:// access protocol and randomised sampling proofs, paying storage providers in ETH to maintain many replicas. Its proposed EIP-7907 advanced as a candidate for Ethereum's Glamsterdam upgrade to relax contract size limits.
Future strategy and roadmap: EthStorage will extend long-term data availability to more rollups and onchain applications, complete its tooling for verifiable front ends, and use provider incentives plus retrieval optimisation to bring cold-data reads down to practical latency.
