Struct SpendPrefixInTransactionV5 

Source 
pub struct SpendPrefixInTransactionV5 {
    pub cv: ValueCommitment,
    pub nullifier: Nullifier,
    pub rk: ValidatingKey,
}
Expand description

The serialization prefix fields of a Spend in Transaction V5.

In V5 transactions, spends are split into multiple arrays, so the prefix, proof, and signature must be serialised and deserialized separately.

Serialized as SpendDescriptionV5 in protocol specification §7.3.

Fields§

§cv: ValueCommitment

A value commitment to the value of the input note.

§nullifier: Nullifier

The nullifier of the input note.

§rk: ValidatingKey

The randomized public key for spend_auth_sig.

impl TrustedPreallocate for SpendPrefixInTransactionV5

The maximum number of sapling spends in a valid Zcash on-chain transaction V5.

If a transaction contains more spends than can fit in maximally large block, it might be valid on the network and in the mempool, but it can never be mined into a block. So rejecting these large edge-case transactions can never break consensus.
