Mempool: Visualisation of both count and size of unconfirmed transactions in the Bitcoin network
The Bitcoin mempool as an interactive graphics: Please stay patient until the page fully loaded and the graphics are generated and rendered.
Time scale matches GMT+2, Timezone Berlin. The page is not cached and the data is recollected minutely, updated and pulled to the webserver every 5 minutes, and displayed after every reload of the page. Statistics running since 2 August 2017, but will be cleared when I reboot my full node.
Open clean version in a single tab/window.
This page displays the number and size of the unconfirmed bitcoin transactions, also known as the transactions in the mempool. It gives a real-time view and shows how the mempool evolves over the time. The transactions are colored by the amount of fee they pay per byte. The data is generated from my full node and is updated every minute. Note that in bitcoin there is no global mempool; every node keeps its own set of unconfirmed transactions that it has seen.
The data is separated into different fee levels given in satoshi per bytes. The lowest colored stripe is for transactions that pay the lowest fee. Higher fee transactions are stacked on top of it. Since miners prefer high fee transactions, a new block usually only removes the top 1000 kB from the queue. If a colored stripe persists over several hours without getting smaller, this means that transactions paying this amount of fee are not confirmed during this time, because there are higher paying transactions that take precedence. If a stripe on the bottom chart is much bigger than on the top chart, the transactions are larger than the average.
You can click on some fee level in the legend to hide all fee levels below that level. This way you can better see how many transactions are competing with that fee level. You can also click in the legend to toggle the visibility of the total fee statistics.
