Current Bitcoin Mempool
Where is my transaction in the mempool?
The chart shows a mempool snapshot from my node. The mempool contains unconfirmed transactions waiting to be included in a block. Each transaction pays a fee and has a size. Transactions paying a higher fee per size (feerate) are usually included earlier than low feerate transactions.
The stacked bars in the chart represent grouped and sorted transactions by their feerate. The bar height of each feerate group corresponds to the amount of transactions in that group. The highest feerate groups appear at the top of the chart descending to lower feerates. Each horizontal line shows one megabyte of transactions. The bars are colorcoded according to their feerate.

Historical Bitcoin Mempool
When was the last time the mempool cleared?
The chart below shows how the mempool evolved over time. An ascending slope means that new transactions came into the mempool. A descending slope means that a new block was found and the transactions in that block have been removed form the mempool.
The timeframe and the y-Axis can be controlled with the buttons below. By count displays the historical mempool by transaction count, by fee displays by fees in Bitcoin and by size by transaction size in vkB.
How much time has passed since the last block?
The chart below shows the arrival times of the last ten blocks. Since finding a valid block (mining) is a random process, the time between two blocks is random. Sometimes blocks are found only seconds apart, sometimes it takes over an hour till a new block is found. On average a new block is found roughly every ten minutes. However, there is no way of accurately estimating when the next block will be found, since mining is a random process.
The time displayed in the chart is the time the blocks arrived over the P2P network. Hovering over a block shows additional information like the transaction count and the block size. The time since the last block is marked red.

SegWit and BIP125-RBF Statistics
How many unconfirmed transactions spend SegWit outputs? How many are replaceable with BIP125 RBF?
This chart shows statistics on SegWit spending and BIP125 Replace-By-Fee signaling transactions in the mempool. Data from the last three hours is displayed. The buttons below switch the display mode between percentage and count.
Replace-By-Fee (RBF) as proposed in BIP 125 allows the replacement of an an unconfirmed transaction with a new version of that transaction paying a higher fee. By signaling RBF the spender indicates that he/she wants to be able to replace that transaction in the future.
