Only first indexation works
Because subscribeNewBlock
only indexes the last finalized block, and forget all the previous since our last indexation.
For example we have:
- first indexation: indexes blocks up to #1000
- finalization event at #1500: indexes only block #1500 (forgetting about blocks [1001;1499]
- finalization event at #2000: indexes only block #2000 (forgetting about blocks [1501;1999]
- etc
