Module types

Types used in aggregation.

Structs

Ack

Acknowledgment (ack) represents a validator’s partial signature on an item. Multiple acks can be recovered into a threshold signature for consensus.

Item

Item represents a single element being aggregated in the protocol. Each item has a unique index and contains a digest that validators sign.

TipAck

Message exchanged between peers containing an acknowledgment and tip information. This combines a validator’s partial signature with their view of consensus progress.

Enums

Activity

Used as Reporter::Activity to report activities that occur during aggregation. Also used to journal events that are needed to initialize the aggregation engine when the node restarts.

Error

Error that may be encountered when interacting with aggregation.

Type Aliases

Epoch

Epoch represents a configuration period in the aggregation protocol. Validators may change between epochs, requiring new threshold signatures.

Index

Index represents the sequential position of items being aggregated. Indices are monotonically increasing within each epoch.
