In Financial Derivatives, What Is the Equivalent of a “Transaction Backlog” in the Mempool?

In financial derivatives, the equivalent of a "transaction backlog" in the mempool is a large, pending order book or a liquidity crunch in a thinly traded market. A large order book with many limit orders far from the market price represents a queue of desired transactions that are "stuck".

A liquidity crunch means there are few willing buyers and sellers, leading to delayed execution and wider bid-ask spreads, analogous to a congested network where transactions take longer to confirm.
