Structs

Block

A Zcash block, containing a header and a list of transactions.

ChainHistoryBlockTxAuthCommitmentHash

A block commitment to chain history and transaction auth.

ChainHistoryMmrRootHash

The root hash of a Merkle Mountain Range chain history tree.

Height

The length of the chain back to the genesis block.

SerializedBlock

Enums

BlockTimeError

TODO: Use this error as the source for zebra_consensus::error::BlockError::Time, and make BlockError::Time add additional context. See https://github.com/ZcashFoundation/zebra/issues/1021 for more details.

Commitment

Zcash blocks contain different kinds of commitments to their contents, depending on the network and height.

CommitmentError

Errors that can occur when checking RootHash consensus rules.

Constants

BLOCK_HASH_SIZE 🔒

A serialized Block hash takes 32 bytes

MAX_BLOCK_BYTES

The maximum size of a Zcash block, in bytes.

ZCASH_BLOCK_VERSION

The Zcash accepted block version.

Traits

TryIntoHeight

Convenience trait for converting a type into a valid Zcash Height.

Type Aliases

HeightDiff

A difference between two Heights, possibly negative.
