5/// An [`AccountComponent`] implementing a no-authentication scheme.
6///
7/// This component provides **no authentication**! It only checks if the account
8/// state has actually changed during transaction execution by comparing the initial
9/// account commitment with the current commitment and increments the nonce if
10/// they differ. This avoids unnecessary nonce increments for transactions that don't
11/// modify the account state.
12///
13/// It exports the procedure `auth_no_auth`, which:
14/// - Checks if the account state has changed by comparing initial and final commitments
15/// - Only increments the nonce if the account state has actually changed
16/// - Provides no cryptographic authentication
17///
18/// This component supports all account types.
