Answer:
The term for a rollup that relies on the assumption that the sequencer processing transactions at layer 2 is honest, and addresses malicious behavior through subsequent penalties is known as “Optimistic Rollup”.
Optimistic Rollup is a layer 2 scaling solution for Ethereum that assumes most transactions will be processed correctly but includes mechanisms to penalize or challenge any incorrectly executed transactions or blocks. It reduces the computational load on the Ethereum main chain by bundling multiple transactions into a single batch and only uploading the data to the main chain when necessary. This optimistic approach allows for efficiency gains while still maintaining security through incentivizing honest behavior and penalizing dishonest actions.
