Implementations§

Source§

impl Blockchain

Source

pub fn new(chain_mmr: Mmr) -> Self

Returns a new Blockchain.

Source

pub fn chain_tip(&self) -> BlockNumber

Returns the tip of the chain, i.e. the number of the latest block in the chain.

Source

pub fn chain_length(&self) -> BlockNumber

Returns the chain length.

Source

pub fn peaks(&self) -> MmrPeaks

Returns the current peaks of the MMR.

Source

pub fn peaks_at(&self, forest: usize) -> Result<MmrPeaks, MmrError>

Returns the peaks of the MMR at the state specified by forest.

§Errors

Returns an error if the specified forest value is not valid for this MMR.

Source

pub fn push(&mut self, block_commitment: RpoDigest)

Adds a block commitment to the MMR. The caller must ensure that this commitent is the one for the next block in the chain.

Source

pub fn open(&self, pos: usize) -> Result<MmrProof, MmrError>

Returns an MmrProof for the leaf at the specified position.

Source

pub fn as_mmr(&self) -> &Mmr

Returns a reference to the underlying Mmr.

Source

pub fn partial_mmr_from_blocks( &self, blocks: &BTreeSet<BlockNumber>, latest_block_number: BlockNumber, ) -> PartialMmr

Creates a PartialMmr at the state of the latest block (i.e. the block’s chain root will match the hashed peaks of the returned partial MMR). This MMR will include authentication paths for all blocks in the provided set.
