Every unconfirmed transaction is a car. Lane is feerate.Every unconfirmed transaction is a car. Lap speed is block time.Every unconfirmed transaction is a passenger. The queue is the fee market.
Live mempool traffic across the ccnodes fleet. Cars merge onto the highway as
transactions hit the mempool — hotter feerates take the faster top lanes — queue at the
NEXT BLOCK gate, and drive on through the moment a block includes them.
Bigger value, bigger vehicle — click any car for details. Litecoin runs a violet
MWEB sub-track beneath it: confidential MimbleWimble traffic with its own blocks.
Click a chain's road or name to focus on it, big.
Daytona for mempools: every coin races in its own multi-lane band, and lap speed is set
by the chain's block time — fastest chain takes the inside line. The deeper a mempool, the
smaller its cars. When a block is mined the checkered flag waves and its transactions peel
off at that coin's exit. Click any car for details.
Every chain runs its own station. Transactions queue on the platform sorted by fee paid —
when a block is mined a train pulls in and boards from the front of the line. Train length is
set by the chain's max block size, and the loaded wagons show how full the block was. All
departures merge onto one shared mainline — signals keep them from crashing. Click any
passenger for details.

reading the highway
Each road strip is one chain, its node polled live — every car is a real unconfirmed transaction.
Lane = feerate. The top lane is the hottest fees and moves fastest; cheap txs crawl in the bottom lane. A new high-fee tx merges straight into the fast lane.
Car size = transaction value (per-chain tiers: compact → sedan → truck → whale bus). The deeper a chain's mempool, the smaller all of its cars draw, so congestion is visible at a glance.
The NEXT BLOCK gate is the chain tip. Cars queue at the stop line; when a block is mined the light goes green and exactly the cars whose txids are in that block drive through.
Cars that fade out with blinkers were dropped or replaced (RBF, expiry) — they left the mempool without being mined.
Car colour = lane, brightest in the fast lane and dimming toward the cheap one — the same fee ramp the rest of ccnodes uses. On classified chains (Bitcoin first) the roof stripe adds the script type: and an amber outline marks RBF-signalling (replaceable) txs.
Litecoin MWEB sub-track (violet, pinned under Litecoin): MimbleWimble Extension Block traffic from the same node. Amounts and addresses are confidential, so MWEB cars carry no value and are sized by MWEB weight; each LTC block carries an extension block, shown here with its kernel and peg-in/peg-out counts.
Click any car for value, fee, feerate, size, and an explorer link.
Click anywhere else on a road (or its name) to focus on that chain alone, drawn big — horizontal or vertical, and the link is shareable. Esc or all chains goes back.
reading the speedway
Each concentric band is one chain; every car is a live unconfirmed transaction racing laps.
Lap speed = block time. The fastest chain takes the inside line; Bitcoin's 10-minute blocks cruise the outside wall.
Within a band the inner sub-lane runs slightly hotter, so packs genuinely overtake.
Car size = transaction value, shrunk by mempool depth — a deep queue means smaller, denser traffic.
Checkered flag: when a chain mines a block, its included cars glow, race to that coin's offramp, and peel off the track.
The pit board (center) shows each chain's queue depth, height, and block cadence.
reading the railway
Each chain is a train station. Every passenger on the platform is a real unconfirmed transaction; passenger size tracks transaction value.
The queue is sorted by fee paid — the fee market is the boarding order. Watch a new high-fee tx walk in and cut the line; cheap txs drift to the back.
A mined block is a train. It pulls in, boards from the front of the queue, and departs. Wagon count comes from the chain's max block size; how many wagons show cargo is how full the block actually was.
One shared mainline. All departures curve onto the same track — junction signals and follow-the-leader spacing keep them from crashing.
Click any passenger (queued, boarding, or ghost) for value, fee, feerate, size, and an explorer link.
