BTC: Local Mempool Memory Usage — Sample Maximum

Bitcoin Local Mempool Memory Usage — Sample Maximum was 207,415,672 bytes on 9 Nov 2026 (latest daily value).

The highest mempool memory usage sampled from our own Bitcoin Core node in each UTC hour or day, in bytes.

Why use it. Show the peak memory this node's mempool occupied within each period, for comparison with its memory limit. How to read it. Each point is the maximum of the available samples in the UTC hour or day, so one high sample sets it; it is not time-weighted. Compare with the memory limit chart in the same unit. Memory usage is distinct from transaction virtual size, which has its own chart. Samples are irregular prospective observations, beginning 2026-10-03, with no earlier observations reconstructed. Mempool policy and visibility are local to this node.

Calculation. Sample the local mempool memory usage of our own validated Bitcoin Core node at irregular times. For each UTC hour or day, take the maximum of the available observations. Coverage records the first and last observation, sample count and gaps.
