Knowledge Notes | Mempool
① When the mempool is full, nodes first remove transactions with the lowest fee rates. Transactions with fees that are too low may be evicted from the mempool.
② Bitcoin supports Replace-by-Fee (RBF): sign a new transaction spending the same inputs with a higher fee to replace the unconfirmed transaction.
③ Before sending bitcoin, check the current fee levels and set your fee rate accordingly. If it’s too low, your transaction may be stuck for a long time.
