    May 2023

  2. ENS and subname NFT subnames Digital Twins Gasless names 01.

    02. 03. 04.

  3. What is ENS subname?

  4. @ensdomains What is ENS? 0x5a384227b65fa093dec...

  5. @ensdomains Ethereum Name Service matoken.eth

  6. @ensdomains Subname

  7. @ensdomains Subname - No registration fee - Anyone can issue

    - Great way to onboard new users

  8. @ensdomains Subname - No registration fee - Anyone can issue

    - Great way to onboard new users - Not NFT (unlike .eth) - Cost gas

  9. NFT subnames

  10. @ensdomains Problem recap - Not NFT - Parent can override

    child - Parent expiration affect subnames

  11. @ensdomains Solution: Name Wrapper

  12. @ensdomains Parent Fuses

  13. @ensdomains Owner Controlled Fuses

  14. @ensdomains Examples

  15. @ensdomains Fuse book https://mdtanrikulu.github.io/fusebook

  16. Digital twins

  17. @ensdomains Problem: I want to issue subdomains to my NFT

    owners - Ownership of subdomain follows the ownership of the NFT

  18. @ensdomains Solution: ENSIP 10: Wildcard . .eth .doodle.eth *.doodle.eth resolve(“1.doodle.eth”)

    resolve(“1.doodle.eth”)

  19. @ensdomains Solution: ENSIP 10: Wildcard . .eth .doodle.eth *.doodle.eth resolve(“1.doodle.eth”)

    resolve(“1.doodle.eth”) Doodle NFT ownerOf(1)

  20. @ensdomains Example in the wild https://twitter.com/adraffy/status/1653679293418049536 - Gasless - No

    events - 0.05 eth to map the name - “experimental”

  21. Gasless

  22. @ensdomains Problem: I want to issue subdomains at events to

    participants for “free” - Creating subnames cost gas

  23. @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

  24. @ensdomains Intuition => NFT metadata https://leftasexercise.com/2021/10/03/using-nft-metadata-to-safely-store-digital-assets/

  25. @ensdomains cb.id

  26. @ensdomains lens.xyz

  27. @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

  28. @ensdomains Demo pack https://github.com/gskril/ens-offchain-registrar

  29. Issue subdomains to your community matoken.eth twitter: @makoto_inoue SPAGHETTETH II
