4. @ensdomains What is ENS? 0x5a384227b65fa093dec...
5. @ensdomains 1. Ethereum Name Service matoken.eth
6. @ensdomains 2. Dweb
7. @ensdomains 3. Avatar Text Record
8. @ensdomains POAP x IYK x ENS
9. ENS Offchain integration
10. @ensdomains ENS ❤ Argent
11. @ensdomains ENS 💔 Argent
12. @ensdomains - 3 request model - Revert, Request, Verify Solution 1: CCIP-read (EIP 3668) Secure Offchain data retrieval
13. @ensdomains Solution 2: Wildcard . .eth .matoken.eth *.matoken.eth resolve(“a.matoken.eth”) resolve(“a.matoken.eth”) L2/Offchain
14. @ensdomains Example: Coinbase Wallet (cb.id)
15. @ensdomains cb.id
16. @ensdomains cb.id
17. @ensdomains lens.xyz
18. ENS on L2 and Starknet
19. @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
20. @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
21. @ensdomains - 1. eth_GetProof - 2. Check L2 state root on L1 - 3. Verify Storage Proof with Merkle Tree Lib L2 (Optimistic)Resolver
22. @ensdomains - 1. eth_GetProof - 2. Check L2 state root on L1 - 3. Verify Storage Proof with Merkle Tree Lib L2 (Optimistic)Resolver
23. @ensdomains - 1. eth_GetProof - 2. Check L2 state root on L1 - 3. Verify Storage Proof with Merkle Tree Lib L2 (Optimistic)Resolver
24. @ensdomains - Non EVM - Different Address Format - Different hash function/prover - (pedersen over keccak256) Starknet / Zk Rollup
25. @ensdomains - [✔] STRK Address format - [ ] pathfinder_getProof - [ ] pedersen hash - [ ] ENS contracts in Cairo Path to ENS on Starknet
