What is ENS? ENS offchain integration ENS on L2 and
Starknet 01. 02. 03.
What is ENS?
@ensdomains What is ENS? 0x5a384227b65fa093dec...
@ensdomains 1. Ethereum Name Service matoken.eth
@ensdomains 2. Dweb
@ensdomains 3. Avatar Text Record
@ensdomains POAP x IYK x ENS
ENS Offchain integration
@ensdomains ENS ❤ Argent
@ensdomains ENS 💔 Argent
@ensdomains - 3 request model - Revert, Request, Verify Solution
1: CCIP-read (EIP 3668) Secure Offchain data retrieval
@ensdomains Solution 2: Wildcard . .eth .matoken.eth *.matoken.eth resolve(“a.matoken.eth”) resolve(“a.matoken.eth”)
L2/Offchain
@ensdomains Example: Coinbase Wallet (cb.id)
@ensdomains cb.id
@ensdomains cb.id
@ensdomains lens.xyz
ENS on L2 and Starknet
@ensdomains Offchain - DBMS / Side chains - No or
little gas - Truested - In Production - cb.id/.lens Offchain vs L2 L2 - Optimistic/ZK Rollup - Little gas - On chain verifiable - Trust Minimized - No production (Yet) - POC on Optimism/Arbitrum
@ensdomains L2 integration per application/wallet foo.cb.id bar.cb.id baz.cb.id foo.argent.xyz bar.argent.xyz
baz.argent.xyz foo.lens.xyz bar.lens.xyz baz.lens.xyz cb.id argent.xyz lens.xyz Offchain
@ensdomains - 1. eth_GetProof - 2. Check L2 state root

@ensdomains - Non EVM - Different Address Format - Different
hash function/prover - (pedersen over keccak256) Starknet / Zk Rollup
@ensdomains - [✔] STRK Address format - [ ] pathfinder_getProof
- [ ] pedersen hash - [ ] ENS contracts in Cairo Path to ENS on Starknet
