ADVZ dispersal data

Fields

view_number: TYPES::View

The view number for which this VID data is intended

epoch: Option<TYPES::Epoch>

Epoch the data of this proposal belongs to

target_epoch: Option<TYPES::Epoch>

Epoch to which the recipients of this VID belong to

payload_commitment: ADVZCommitment

VidCommitment calculated based on the number of nodes in target_epoch.

shares: BTreeMap<TYPES::SignatureKey, ADVZShare>

A storage node’s key and its corresponding VID share

common: ADVZCommon

VID common data sent to all storage nodes

Implementations

impl<TYPES: NodeType> ADVZDisperse<TYPES>

async fn from_membership( view_number: TYPES::View, vid_disperse: JfVidDisperse<ADVZScheme>, membership: &EpochMembershipCoordinator<TYPES>, target_epoch: Option<TYPES::Epoch>, data_epoch: Option<TYPES::Epoch>, ) -> Self

Create VID dispersal from a specified membership for the target epoch. Uses the specified function to calculate share dispersal Allows for more complex stake table functionality

pub async fn calculate_vid_disperse( payload: &TYPES::BlockPayload, membership: &EpochMembershipCoordinator<TYPES>, view: TYPES::View, target_epoch: Option<TYPES::Epoch>, data_epoch: Option<TYPES::Epoch>, ) -> Result<(Self, Duration)>

Calculate the vid disperse information from the payload given a view, epoch and membership, If the sender epoch is missing, it means it’s the same as the target epoch.

Errors

Returns an error if the disperse or commitment calculation fails

pub fn payload_byte_len(&self) -> u32

Returns the payload length in bytes.
