This feature allows transactions to be processed more quickly and cost-effectively, as it reduces the need for exhaustive validations on each operation. Instead of requiring every transaction to be verified by all nodes in the network, Optimistic Rollup groups multiple transactions into a single batch, which is then sent to the main chain. This not only alleviates the load on the main network but also allows users to enjoy lower transaction fees and faster confirmation times. Additionally, Optimistic Rollup employs a fraud-proof mechanism, where participants can challenge suspicious transactions, thus ensuring the integrity of the network.
