Epoch

On Nimbora, keeping track of each processed batch is crucial. Since Starknet and Ethereum are asynchronous in their essence, we need a mechanism to synchronize the contracts state between both chains. To achieve that, each processed and closed batch sent from L2 to L1 contains an epoch. This way we ensure that:

• Batches are processed in the correct order.
• No batch can be processed more than once.
