Both are Rollups, so why do some take a week to withdraw back to mainnet while others don’t?
First, a definition: currently, most Rollups use a single sequencer to receive, order, and batch user transactions. Users generally submit their transactions to the sequencer first.
The underlying logic: validity proofs follow the approach of “prove first, confirm afterward.” Correctness depends on the cryptographic proof itself; the trade-off is that generating proofs requires a great deal of computation.
$ARB and $OP use Optimistic Rollups, while $STRK uses the ZK approach.
When you see a project claiming stable, high returns, be extra skeptical.
