Mempool Analysis and Simulation
summary
A new MFF mempool format plus bcq/cqdb libraries record every transaction event, including raw invalidated transactions and blocks, in append‑only cluster files (one cluster per 2016 blocks) so logs are seekable and replayable; recordings run ≈15 MB/day, deduplicate objects by reference, and show mempool churn (99.2% inserts, tens of thousands of invalidations) and oddities like a transaction referenced ~1,900 times and cases where miners ignore RBF so an original low‑fee tx is mined despite a higher‑fee replacement.
