BTC: Local Mempool Memory Usage — Sample Mean

Bitcoin Local Mempool Memory Usage — Sample Mean was 177,667,965.4 bytes on 9 Nov 2026 (latest daily value).

The average of mempool memory usage samples from our own Bitcoin Core node in each UTC hour or day, in bytes.

Why use it. Summarize the memory this node's mempool occupied across each period, for comparison with its memory limit. How to read it. Each point is the arithmetic mean of the available irregular samples in the UTC hour or day, not a time-weighted network average, so unevenly spaced samples weight parts of the period differently. 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 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 arithmetic mean of the available samples, normalized to 40 significant decimal digits for publication. Coverage records the first and last observation, sample count and gaps.
