# paperproof-validator > Formal Proof Visualization and Verification for Lean 4 **Version**: 1.0.0 **Trit**: -1 (Validator - verifies proof correctness) **Bundle**: verification **Status**: ✅ New (Lean 4 theorem proof visualization) **Repository**: [Paper-Proof/paperproof](https://github.com/Paper-Proof/paperproof) --- ## Overview **Paperproof Validator** transforms formal Lean 4 proofs into intuitive, paper-like visualizations. It bridges the gap between abstract formal proofs and human understanding by displaying how hypotheses and goals evolve throughout a proof. **Key Innovation**: Makes formal proofs accessible by visualizing proof structure in a way that mirrors mathematical notation on paper. ### What Paperproof Does Instead of abstract Lean code: ```lean theorem example : P → Q := by intro h apply some_lemma exact h.right ``` Paperproof shows: ``` ┌─────────────────────────────────────┐ │ Hypotheses (green nodes): │ │ - h : P │ ├─────────────────────────────────────┤ │ Goal (red node): │ │ - Q │ ├─────────────────────────────────────┤ │ Tactics (transparent): │ │ - apply some_lemma │ │ - exact h.right │ └─────────────────────────────────────┘ ``` --- ## Architecture ### Three Core Components #### 1. **Lean 4 Library Integration** ```lean import Paperproof theorem my_theorem : P ∧ Q → R := by -- Paperproof aut
