There's a narrative out there that ZK Rollups will be able to do everything that Optimistic Rollups do but better.

This is a disappointing comment
@el33th4xor
.
The nomad hack was a smart contract bug that completely bypassed their proof mechanism, and has absolutely no relation to the security of Optimistic Rollups.
Please don’t try to gain cheap points by misleading your community.
Nomad uses a similar design principle as optimistic rollups. This hack proves that the claim that optimistic rollups are inherently more secure is just plain old wrong.

Arbitrum Orbit’s elastic block times is a killer feature.
Blocks are produced up to 4 times a second (super fast UX).

This is funny but also such a sad reflection on the state of many abusing the term L2 for marketing/growth.
