EIP-4844 will discard the DA data older than 18 days. In this talk, we introduce EthStorage, an Ethereum L2 solution to offer long-term available solution for EIP-4844 BLOBs with on-chain proof of storage verification.
EIP-4844 is the much anticipated native Ethereum data availability (DA) solution in the upcoming Ethereum Cancun upgrade. However, to limit the storage requirement of the validators, EIP-4844 will discard the DA data (namely binary large objects, BLOBs) older than 18 days. In this talk, we introduce EthStorage, an Ethereum L2 solution to offer long-term available solution for EIP-4844 BLOBs with on-chain proof of storage verification. By indexing the BLOBs on-chain and storing BLOBs off-chain, EthStorage can scale to hundreds of Terabytes or even Petabytes at 1/100x to 1/1000x of Ethereum storage cost. We will demonstrate the EthStorage testnet that is integrated with EIP-4844 on the Ethereum testnet, and showcase prototypes for new Ethereum applications like vitalik's blog, decentralized Dropbox, dynamic NFTs, etc.
Qi founded EthStorage in 2022 and has recently received a grant from the Ethereum Foundation for his proposal on Proof of Storage on L2 Dynamic Datasets with an Ethereum L1 Contract. He also receives a personal grant from Vitalik and a grant from EF for DAS work. Qi is active in Ethereum ecosystem contributor (ethresear.ch / magician), and is the author/coauthor of EIP/ERC-4804/4972/5018/5027/6150.
Qi also founded QuarkChain in 2018, which is a flexible, scalable, and user-oriented blockchain that applies state-sharding technology. Before QuarkChain, Qi worked as a senior engineer at Google and Facebook in the US. Qi got his Ph.D. from the Georgia Institute of Technology.
