Transaction pool information.

Fields

tip_hash: Byte32

The associated chain tip block hash.

Transaction pool is stateful. It manages the transactions which are valid to be commit after this block.

tip_number: BlockNumber

The block number of the block tip_hash.

pending_size: usize

Count of transactions in the pending state.

The pending transactions must be proposed in a new block first.

proposed_size: usize

Count of transactions in the proposed state.

The proposed transactions are ready to be commit in the new block after the block tip_hash.

orphan_size: usize

Count of orphan transactions.

An orphan transaction has an input cell from the transaction which is neither in the chain nor in the transaction pool.

total_tx_size: usize

Total count of transactions in the pool of all the different kinds of states.

total_tx_cycles: Cycle

Total consumed VM cycles of all the transactions in the pool.

min_fee_rate: FeeRate

Fee rate threshold. The pool rejects transactions which fee rate is below this threshold.

The unit is Shannons per 1000 bytes transaction serialization size in the block.

last_txs_updated_at: u64

Last updated time. This is the Unix timestamp in milliseconds.

tx_size_limit: u64

Limiting transactions to tx_size_limit

Transactions with a large size close to the block size limit may not be packaged, because the block header and cellbase are occupied, so the tx-pool is limited to accepting transaction up to tx_size_limit.

max_tx_pool_size: u64

Total limit on the size of transactions in the tx-pool
