A one-lane chain keeps one arrival in the next slot. A blockDAG keeps both arrivals, then orders them.
Watch first
Two deliveries hit the counter together.
Both counters receive the same two blocks.
Block A+Block B
same arrival
One next slotBlock A stays. Block B waits outside this record.BlockDAG recordBlock A and Block B stay. Their order can follow.
Two arrivals are ready. The counters are filing the same input.
Try different arrivals
The counters are ready. Send one block or send two together.
Single-chain model
There is one next place. In a collision, one arrival is kept and the other is excluded from this record.
received 0kept 0excluded 0
BlockDAG model
Valid arrivals remain in the record. Parent references connect both arrivals to the history they extend.
received 0kept 0excluded 0
The detailed filing will appear after you send an arrival.
Field notes: This is a simplified model with the same arrivals sent to both lanes. The rate and delay are model inputs, not a live network reading. A block excluded by the single-chain model still represents work that was performed in the input.
