Fields

config: TransitionFrontierConfig

genesis: TransitionFrontierGenesisState

Genesis block generation/proving state

best_chain: Vec<AppliedBlock>

Current best known chain, from root of the transition frontier to best tip

needed_protocol_states: BTreeMap<StateHash, MinaStateProtocolStateValueStableV2>

Needed protocol states for applying transactions in the root scan state that we don’t have in the best_chain list.

candidates: TransitionFrontierCandidatesState

sync: TransitionFrontierSyncState

Transition frontier synchronization state

blacklist: BTreeMap<StateHash, u32>

Blocks which had valid proof but failed block application or other validations after it reached transition frontier.

chain_diff: Option<BestTipDiff>

The diff of Self::best_chain with the previous one

archive_enabled: bool

Archive mode enabled

Implementations

impl TransitionFrontierState

pub fn new(config: TransitionFrontierConfig, archive_enabled: bool) -> Self

pub fn best_tip(&self) -> Option<&ArcBlockWithHash>

pub fn root(&self) -> Option<&ArcBlockWithHash>

pub fn best_tip_breadcrumb(&self) -> Option<&AppliedBlock>

pub fn root_breadcrumb(&self) -> Option<&AppliedBlock>

pub fn contains_transaction(&self, hash: &TransactionHash) -> bool

FIXME Note(adonagy): This can be expensive, keep a map with all the tx hashis in the best chain

pub fn get_state_body( &self, hash: &StateHash, ) -> Option<&MinaStateProtocolStateBodyValueStableV2>

Looks up state body by state hash.

pub fn maybe_make_chain_diff( &self, new_chain: &[AppliedBlock], ) -> Option<BestTipDiff>

Create a diff between the old best chain and the new one This is used to update the transaction pool

pub fn resources_usage(&self) -> Value

impl TransitionFrontierState

pub fn reducer( state_context: Substate<'_, Self>, action: TransitionFrontierActionWithMetaRef<'_>, )
