Ethereum

Gm, what still confuses you about rollups?

In the past, something that was confusing for me was commingling transaction finality and the withdrawal challenge period

Interesting question! I hadn't really thought about this before. Indexers are the unsatisfying answer, I guess. Not sure what the considerations are for adding this to the protocol.

With so many more blocks and transactions, how can I monitor for the fees my addresses pay without having to read every single transaction?

how do you "prove" censorship resistance without shared sequencing?

Where is there no OP liquidity on Arbitrum and vice versa?
