The EthStorage team proposed the web3:// access protocol and the EthStorage second-layer storage protocol, aiming to help decentralized applications (DAPP) achieve true trustlessness. Most of the current DAPP front-ends and databases are not deployed on Ethereum and cannot fully inherit the security of Ethereum. The web3:// protocol allows front-end code to be deployed and accessed through smart contracts, while the EthStorage protocol reduces on-chain data storage costs through PoRA and zero-knowledge proofs. These two technologies enable DAPP to get closer to Ethereum’s decentralized vision and achieve permanent operation and censorship resistance.
