@ensdomains Subname - No registration fee - Anyone can issue
- Great way to onboard new users - Not NFT (unlike .eth) - Cost gas
NFT subnames
@ensdomains Problem recap - Not NFT - Parent can override
child - Parent expiration affect subnames
@ensdomains Solution: Name Wrapper
@ensdomains Parent Fuses
@ensdomains Owner Controlled Fuses
@ensdomains Examples
@ensdomains Fuse book https://mdtanrikulu.github.io/fusebook
Digital twins
@ensdomains Problem: I want to issue subdomains to my NFT
owners - Ownership of subdomain follows the ownership of the NFT
@ensdomains Solution: ENSIP 10: Wildcard . .eth .doodle.eth *.doodle.eth resolve(“1.doodle.eth”)
resolve(“1.doodle.eth”)
@ensdomains Solution: ENSIP 10: Wildcard . .eth .doodle.eth *.doodle.eth resolve(“1.doodle.eth”)
resolve(“1.doodle.eth”) Doodle NFT ownerOf(1)
@ensdomains Example in the wild https://twitter.com/adraffy/status/1653679293418049536 - Gasless - No
events - 0.05 eth to map the name - “experimental”
Gasless
@ensdomains Problem: I want to issue subdomains at events to
participants for “free” - Creating subnames cost gas
@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
@ensdomains Intuition => NFT metadata https://leftasexercise.com/2021/10/03/using-nft-metadata-to-safely-store-digital-assets/
@ensdomains cb.id
@ensdomains lens.xyz
@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
