On November 29th, ENS and the chief developer of the Ethereum Foundation Nick Johnson are in the Ethereum improvement proposal. Initiated the EIP-3668 draft “Durin: Secure Off-Chain Data Retrieval”.
Durin provides a security mechanism for obtaining off-chain data without additional trust assumptions. In order to minimize storage and transaction costs on Ethereum, contract authors have adopted various techniques to transfer data off-chain. Including hashing, recursive hashing (such as MerkleTrees/Tries) and L2 solutions.
1. Interact with “airdrop” contracts, which store the list of recipients under the chain in the Merkel tree.
- View the Token information stored on the L2 solution as if it were in L1.
- Allow data (such as ENS domain) to be delegated to various L2 solutions. There is no need for customers to individually support each solution.
