17. What is ENS subname?
18. @ensdomains Subname
19. @ensdomains Subname - No registration fee - Anyone can issue - Great way to onboard new users
20. @ensdomains Subname - No registration fee - Anyone can issue - Great way to onboard new users - Not NFT (unlike .eth) - Cost gas
21. NFT subnames
22. @ensdomains Problem recap - Not NFT - Parent can override child - Parent expiration affect subnames
23. @ensdomains Solution: Name Wrapper
24. @ensdomains Parent Fuses
25. @ensdomains Owner Controlled Fuses
26. @ensdomains Examples
27. @ensdomains Fuse book https://mdtanrikulu.github.io/fusebook
28. Digital twins
29. @ensdomains Problem: I want to issue subdomains to my NFT owners - Ownership of subdomain follows the ownership of the NFT
30. @ensdomains Solution: ENSIP 10: Wildcard . .eth .doodle.eth *.doodle.eth resolve(“1.doodle.eth”) resolve(“1.doodle.eth”)
31. @ensdomains Solution: ENSIP 10: Wildcard . .eth .doodle.eth *.doodle.eth resolve(“1.doodle.eth”) resolve(“1.doodle.eth”) Doodle NFT ownerOf(1)
32. @ensdomains Example in the wild https://twitter.com/adraffy/status/1653679293418049536 - Gasless - No events - 0.05 eth to map the name - “experimental”
33. Gasless
34. @ensdomains Problem: I want to issue subdomains at events to participants for “free” - Creating subnames cost gas
35. @ensdomains Solution EIP3668: Secure Offchain data retrieval (aka CCIP-read) . .eth .matoken.eth *.matoken.eth resolve(“a.matoken.eth”) resolve(“a.matoken.eth”) L2/Offchain Gateway service
36. @ensdomains Intuition => NFT metadata https://leftasexercise.com/2021/10/03/using-nft-metadata-to-safely-store-digital-assets/
37. @ensdomains cb.id
38. @ensdomains lens.xyz
39. @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
40. @ensdomains Demo pack https://github.com/gskril/ens-offchain-registrar
