Agenda - 1. ENS L2 design considerations - 2. Rollup
agnostic L2 integration - 3. What about other EVM compatible chains? - 4. FAQs
1. ENS L2 design considerations
Most “L2/EVM chain” strategies - 1. Deploy a copy -
2. Select Network - 3. Add Liquidity incentive
ENS “L2/EVM chain” design discussion - 2020 Sep: “A general-purpose
L2-friendly” ENS standard by Vitalik - 2020 Oct: “A general-purpose bridge for Ethereum Layer 2s” by Nick - 2021 Apr: “MVP of ENS on L2 with Optimism” by Nick
ENS “L2/EVM chain” requirement - 1. No “Switch network” for
reading names - 2. No “Pick a winner” (yet) for updating record - 3. Minimise additional trust assumption
2. Rollup agnostic L2 integration
ENS architecture recap - 2 requests model - Swappable resolver
L2 Gateway - 3 requests model - Set gateway per
resolver - Verify with proof at L1

3.What about other EVM compatible chains?
TVL on EVM compatible chains https://twitter.com/richwgalvin/status/1399992712451948546
- Bridge gateway - App gateway - Trusted gateway Alternatives
- Bridge signs the data - Verify bridge signer, not
data Bridge Gateway EVM Chain
Bridge Gateway Pros - Retains the same security assumption Cons
- Bridge needs modification/extension - Signer must be verifiable on L1
- Name owner hosts the gateway - Name owner signs
data - Verify name ownership, not data App Gateway EVM Chain
App Gateway Pros - No dependencies to the bridges Cons
- Each App has to host own gateway - Less trustless
- Name owner hosts the gateway - Name owner signs
data - Verify name ownership, not data Trusted Gateway DBMS
Trusted Gateway Pros - No ENS registry required off L1
Cons - Trusted - No NFT
Comparison
- Registration & Renewal gas cost - Subdomains - Ownership
4. FAQs
Q. Does Registration & Renewal gas cost become cheaper?
A: Not for now - Registry will remain on L1
- Resolver can move to a L2 - Use of Subdomain
Q. Can I create subdomains on L2 and sell as
NFT?
- Wildcard support - https://eips.ethereum.org/EIPS/eip-2544 - NFT support on Registry
A: Yes
Q. How do I prevent from transferring the same name
to different owners on L1 and L2?
- ENS is NFT - NameWrapper for subdomains A: Lock
your name on a cross chain bridge
