Enum zcash_primitives::consensus::BranchId[−][src]

pub enum BranchId {
    Sprout,
    Overwinter,
    Sapling,
    Blossom,
    Heartwood,
    Canopy,
    Nu5,
    ZFuture,
}

Expand description

A globally-unique identifier for a set of consensus rules within the Zcash chain.

Each branch ID in this enum corresponds to one of the epochs between a pair of Zcash network upgrades. For example, BranchId::Overwinter corresponds to the blocks starting at Overwinter activation, and ending the block before Sapling activation.

The main use of the branch ID is in signature generation: transactions commit to a specific branch ID by including it as part of signature_hash. This ensures two-way replay protection for transactions across network upgrades.

See ZIP 200 for more details.

Variants

Sprout

The consensus rules at the launch of Zcash.

Overwinter

The consensus rules deployed by NetworkUpgrade::Overwinter.

Sapling

The consensus rules deployed by NetworkUpgrade::Sapling.

Blossom

The consensus rules deployed by NetworkUpgrade::Blossom.

Heartwood

The consensus rules deployed by NetworkUpgrade::Heartwood.

Canopy

The consensus rules deployed by NetworkUpgrade::Canopy.

Nu5

The consensus rules deployed by NetworkUpgrade::Nu5.

ZFuture

Candidates for future consensus rules; this branch will never activate on mainnet.
