-
-
-> ZKRollup
-
-This contract maintains essential data for zk rollup, including: 1. a list of pending messages, which will be relayed to layer 2; 2. the block tree generated by layer 2 and it's status.
-
-*the message queue is not used yet, the offline relayer only use events in `L1ScrollMessenger`.*
-
