Struct AuthHash

Source 
pub struct AuthHash(pub [u8; 32]);
Expand description

A hash of a transaction’s authorizing data, describing both its effects on the chain state as well as the cryptographic authorization of those effects.

In practice this is simply a hash of the TransactionBody.

The transaction’s binding signature is formed over the transaction’s AuthHash. Because the binding signature is formed using the randomness for the balance commitments for each action, this prevents replaying proofs from one transaction to another without knowledge of the openings of the balance commitments, binding the proofs to the transaction they were originally computed for.
