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.
