BTC: Local Mempool Virtual Size — Sample Minimum
Bitcoin Local Mempool Virtual Size — Sample Minimum was 24,679,389 vbytes on 9 Nov 2026 (latest daily value).
The lowest total virtual size sampled from our own Bitcoin Core node's local mempool in each UTC hour or day, in vbytes.
Why use it. Show the least transaction data, in virtual bytes, this node's mempool held within each period. How to read it. Each point is the minimum of the available samples in the UTC hour or day, so one low sample sets it; it is not time-weighted. Virtual size is distinct from the node's mempool memory usage, 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, so this is one node's view, not a network-wide figure.
Calculation. Sample the local mempool virtual size of our own validated Bitcoin Core node at irregular times. For each UTC hour or day, take the minimum of the available observations. Coverage records the first and last observation, sample count and gaps.
