### Architecture
Typically you can setup a 3 nodes sequencer cluster, each one with op-conductor running alongside the sequencer in different regions / AZs.

1. Leadership transfer triggered by raft consensus protocol (network partition, etc)
1. In this case, a new leader will be elected regardless of its sync status, it could be behind for a few blocks
2. The solution is to simple, wait until the elected leader catch up to tip (same as the FSM tip)

2. Leadership transfer triggered by us (Conductor detected unhealthy sequencer)
1. In this case, we have the choice to determine which node to transfer leadership to, we can simply query the latest block from candidates within the network and transfer directly to the one with the most up to date blocks.
