Struct Transaction

Source
pub struct Transaction {
    pub calls: Vec<DarkLeaf<ContractCall>>,
    pub proofs: Vec<Vec<Proof>>,
    pub signatures: Vec<Vec<Signature>>,
}
Expand description

A Transaction contains an arbitrary number of ContractCall objects, along with corresponding ZK proofs and Schnorr signatures.

DarkLeaf is used to map relations between contract calls in the transaction.

Fields§

§calls: Vec<DarkLeaf<ContractCall>>

Calls executed in this transaction

§proofs: Vec<Vec<Proof>>

Attached ZK proofs

§signatures: Vec<Vec<Signature>>

Attached Schnorr signatures
