KQ-655 · MEMPOOL/QUEUE

Mempool Queue

The waiting room, ordered by what each transaction pays. Rows sort by fee and carry layout on glide, so a reorder is the list rearranging itself and every row travels to its new place; an arrival drops in from a step above on snap and a mined transaction leaves on the exit ease. Your row is washed, ringed, and named in words, and bumping its fee climbs it past the cut line that marks the next block, flashing a wash keyed to the new rank so it fires once per climb and never on a slide backwards. The bump button sits in the tab order and says what fee it would offer.
