It's annoying that Ethereum takes 15min to finalize transaction.

Or 64 blocks.

You have to wait until money is freely available in your CEX account (to withdraw).

And it puts risks for cross-chain bridges. So bridges might take the risk of reorg if they want to offer users fast bridging experience.

Similarly for optimistic rollups.

Or imagine for big purchases in stablecoins face-to-face (if they were common). you'd need wait 15 awkward minutes until it's finalized.

Can't wait for Single Slot Finality (SSF) hard fork but not sure if it's coming in 2026.
