Expand description
Struct representing a forked blockchain state.
An overlay over the original blockchain is used, containing all pending to-write records. Additionally, each fork keeps a vector of valid pending transactions hashes, in order of receival, and the proposals hashes sequence, for validations.
Fields§
§blockchain: Blockchain
Canonical (confirmed) blockchain
overlay: BlockchainOverlayPtr
Overlay cache over canonical Blockchain
module: PoWModule
Current PoW module state,
proposals: Vec<HeaderHash>
Fork proposal hashes sequence
diffs: Vec<SledDbOverlayStateDiff>
Fork proposal overlay diffs sequence
mempool: Vec<TransactionHash>
Valid pending transaction hashes
targets_rank: BigUint
Current fork mining targets rank, cached for better performance
hashes_rank: BigUint
Current fork hashes rank, cached for better performance
Implementations§
Source§impl Fork
impl Fork
pub async fn new(blockchain: Blockchain, module: PoWModule) -> Result<Self>
Sourcepub async fn append_proposal(&mut self, proposal: &Proposal) -> Result<()>
pub async fn append_proposal(&mut self, proposal: &Proposal) -> Result<()>
Auxiliary function to append a proposal and update current fork rank.
Sourcepub fn last_proposal(&self) -> Result<Proposal>
pub fn last_proposal(&self) -> Result<Proposal>
Auxiliary function to retrieve last proposal.
Sourcepub fn get_next_block_height(&self) -> Result<u32>
pub fn get_next_block_height(&self) -> Result<u32>
Auxiliary function to compute forks’ next block height.
Sourcepub async fn unproposed_txs(
&self,
blockchain: &Blockchain,
verifying_block_height: u32,
block_target: u32,
verify_fees: bool,
) -> Result<(Vec<Transaction>, u64, u64)>
pub async fn unproposed_txs( &self, blockchain: &Blockchain, verifying_block_height: u32, block_target: u32, verify_fees: bool, ) -> Result<(Vec<Transaction>, u64, u64)>
Auxiliary function to retrieve unproposed valid transactions, along with their total gas used and total paid fees.
Sourcepub fn full_clone(&self) -> Result<Self>
pub fn full_clone(&self) -> Result<Self>
Auxiliary function to create a full clone using BlockchainOverlay::full_clone. Changes to this copy don’t affect original fork overlay records, since underlying overlay pointer have been updated to the cloned one.
