Summary
The backlog of potential blocks to confirm can be considered unbounded due to writing blocks to the ledger on disk. This persisting of unconfirmed blocks on disk may not be necessary so options for bounding the backlog, such as keeping unconfirmed blocks only in memory, are being explored.
What problem would be solved by this feature?
By keeping the backlog bounded, disk usage or unconfirmed blocks can be reduced.
