Application

1. \( \StateProofStrengthTarget = 256 \) is the value set for State Proofs of type \(0 \). Other types of State Proofs might be added in the future. \( \StateProofStrengthTarget = \mathrm{target_{PQ}} \) is set to achieve post-quantum security for State Proof. For further details, refer to the State Proofs normative specification. ↩
