   - **manual:** local confirmation requests (via rpc)
 - handles adding a block to the priority queue
   - dependents must be confirmed
-- every 5m the scheduler is populated using the backlog
+- every 5m the scheduler is populated using the pool of unconfirmed blocks
 - when there is a vacancy in the active election container it will check both queues (manual & priority) and add the top block (will be changed in v22.1)
   - a block starts of with a passive election state, unless it is added from the priority queue and previously had an election
 - upon starting an election, a node will generate & broadcast votes for that election (see [broadcasting a vote](#broadcasting-a-vote))
