Estimate the fee rate required for a transaction to be included in the next block.
Declared in <policy/fees/mempool_estimator.h>
class MemPoolFeeRateEstimator;Uses Bitcoin Core's block-building algorithm to generate a block template from the mempool, then calculates percentile fee rates from the selected chunks: the 75th percentile is returned as the economical estimate and the 50th percentile as the conservative estimate.
