Live mempool traffic across the ccnodes UTXO 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.
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. Ethereum has a
hidden route: private order flow that never touched the public queue rolls in through
the tunnel and boards directly. 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.
Ethereum's tunnel: ~a third of mainnet txs never touch the public mempool (Flashbots Protect, MEV bundles). Those merge from the tunnel mouth right at the gate, the moment the block mints.

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.

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.
Ethereum's hidden route: private order flow (Flashbots, MEV bundles, builder-direct) never stood in the public queue — those txs roll in through the tunnel under the platform and board the rear wagons directly, drawn in violet.
