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.
• CountedHeader

• Height
  The length of the chain back to the genesis block.
• SerializedBlock
  A serialized block.

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.
