BTC: Local Mempool Memory Usage — Last Sample

Bitcoin Local Mempool Memory Usage — Last Sample was 202,950,240 bytes on 9 Nov 2026 (latest daily value).

Memory used by our own Bitcoin Core node's local mempool at the latest sample in each UTC hour or day, in bytes.

Why use it. Follow how much memory this node's mempool occupies, for comparison with its memory limit. How to read it. Each point is the latest sample in the UTC hour or day, not a time average. Higher values mean the mempool used more memory when sampled; 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, publish the latest sample. Coverage records the first and last observation, sample count and gaps.
