Crate zksync_consensus_storage

Expand description

Abstraction for persistent data storage. It provides schema-aware type-safe database access.

Modules§

BlockStore: A wrapper around a PersistentBlockStore which adds caching blocks in-memory and other useful utilities.
BlockStoreRunner: Runner of the BlockStore background tasks.
BlockStoreState: State of the BlockStore: continuous range of blocks.
ChonkyV2State: The struct that contains the state of a ChonkyBFT v2 replica to be persisted.
Proposal: A payload of a proposed block which is not known to be finalized yet. Replicas have to persist such proposed payloads for liveness: consensus may finalize a block without knowing a payload in case of reproposals. Currently we do not store the BlockHeader, because it is always available in the LeaderPrepare message.
ReplicaState: The struct that contains the replica state to be persisted.

Last: Last block in the block store (see BlockStoreState). Note that the commit qc is required in the case the block has been finalized by the consensus.
