pub struct BatchValidator { /* private fields */ }
Expand description

Batch validation context for Sapling.

This batch-validates Spend and Output proofs, and RedJubjub signatures.

Signatures are verified assuming ZIP 216 is active.

Implementations§

source§

impl BatchValidator

source

pub fn new() -> Self

Constructs a new batch validation context.

source

pub fn check_bundle<V: Copy + Into<i64>>( &mut self, bundle: Bundle<Authorized, V>, sighash: [u8; 32] ) -> bool

Checks the bundle against Sapling-specific consensus rules, and adds its proof and signatures to the validator.

Returns false if the bundle doesn’t satisfy all of the consensus rules. This BatchValidator can continue to be used regardless, but some or all of the proofs and signatures from this bundle may have already been added to the batch even if it fails other consensus rules.

source

pub fn validate<R: RngCore + CryptoRng>( self, spend_vk: &SpendVerifyingKey, output_vk: &OutputVerifyingKey, rng: R ) -> bool

Batch-validates the accumulated bundles.

Returns true if every proof and signature in every bundle added to the batch validator is valid, or false if one or more are invalid. No attempt is made to figure out which of the accumulated bundles might be invalid; if that information is desired, construct separate BatchValidators for sub-batches of the bundles.
