Degen

Re-upping my post from 1.5 years ago on "layer 3s":

The summary is that layer 3s don't magically improve throughput even more, though they can reduce some fixed costs of batch publishing and deposits/withdrawals.

L3s:
(1) “Rollups on top of rollups” for scalability shouldn’t be default L3 use case
(2) L3 as a “layer for custom functionality of different use cases” = ok
(3) /degen chain on @base - implements Arbitrum to switch native token and support smart contract dev in more languages (eg Rust), aligns with (2)
