Struct NodeService

Source 
pub struct NodeService {
    pool: Arc<Pool>,
    block_producer: BlockProducer,
    miner: Miner,
    fee_history: FeeHistoryService,
    filters: Filters,
    filter_eviction_interval: Interval,
}
Expand description

The type that drives the blockchain’s state

This service is basically an endless future that continuously polls the miner which returns transactions for the next block, then those transactions are handed off to the backend to construct a new block, if all transactions were successfully included in a new block they get purged from the Pool.

Fields§

§pool: Arc<Pool>

The pool that holds all transactions.

§block_producer: BlockProducer

Creates new blocks.

§miner: Miner

The miner responsible to select transactions from the pool.

§fee_history: FeeHistoryService

Maintenance task for fee history related tasks.

§filters: Filters

Tracks all active filters

§filter_eviction_interval: Interval

The interval at which to check for filters that need to be evicted
