Detailed Description

Options struct containing options for constructing a CTxMemPool.

Default constructor populates the struct with sane default values which can be modified.

Most of the time, this struct should be referenced as CTxMemPool::Options.

max_datacarrier_bytes

std::optional<unsigned> kernel::MemPoolOptions::max_datacarrier_bytes {DEFAULT_ACCEPT_DATACARRIER ? std::optional{MAX_OP_RETURN_RELAY} : std::nullopt}

A data carrying output is an unspendable output containing data.

The script type is designated as TxoutType::NULL_DATA.

Maximum size of TxoutType::NULL_DATA scripts that this node considers standard. If nullopt, any size is nonstandard.

min_relay_feerate

CFeeRate kernel::MemPoolOptions::min_relay_feerate {DEFAULT_MIN_RELAY_TX_FEE}

A fee rate smaller than this is considered zero fee (for relaying, mining and transaction creation).
