Optimistic Rollup Mechanics

Optimistic rollup mechanics operate on the assumption that all transactions are valid unless proven otherwise by a fraud proof. Unlike other systems that verify every transaction immediately, these rollups allow for a period where participants can challenge incorrect state updates.

If no fraud is detected within the challenge window, the transactions are considered finalized. This mechanism significantly reduces the computational burden on the main chain because only contested transactions require intensive verification.

It is a highly efficient way to scale smart contract platforms while inheriting the security of the underlying base layer.
