BTC: Local Mempool Transactions with Unconfirmed Parents

Bitcoin Local Mempool Transactions with Unconfirmed Parents was 65,794 transactions on 9 Nov 2026 (latest daily value).

Captured transactions with at least one direct unconfirmed parent in this local mempool.

Why use it. See how many pending transactions depend directly on other captured transactions. How to read it. A transaction is counted once regardless of parent count. This is not a count of packages or transitive ancestors. Empty populations are zero. The hour/day point is the last actual accepted sample in that UTC bucket, not a time average. Earlier or missing samples and departed/replaced transactions are not reconstructed. Read capture clocks and gap coverage; a final sampling-period label does not confirm its transactions.

Calculation. Use one validated Core capture with consistent local clocks and dependencies. Validate captured parent membership and dependency facts, then count transactions with a nonempty direct-parent list. Age is local capture Unix second minus Core-reported local entry second, not network first-seen time or expected confirmation wait. Transactions have equal weight; virtual size does not weight age. Only one local Bitcoin Core node is observed; this is not a worldwide mempool census or a confirmation forecast.
