Formal Verification with Z3
Don't guess. Prove. Z3 turns 'might be vulnerable' into 'is exploitable.'
Real-world application: Engineers who can apply Z3 SMT solvers for formal verification of AI-generated code demonstrate cutting-edge security verification skills valued by security-focused teams.
What you will learn
- Understand how Z3 SMT solvers encode code behavior as formal constraints
- Explain the COBALT analysis pipeline for AI code verification
- Apply Z3 satisfiability witnesses to prove exploitability
- Understand AxiomGuard (deterministic Z3 verification with zero false positives)
- Understand Chiasmus (MCP server for formal verification) and ProvekIt (LLM+Z3 verifier for TypeScript)
Introduction
Formal Verification with Z3
Objective
Run the COBALT pipeline simulation on AI-generated code with Z3 formal verification. Observe satisfiability witnesses, AddressSanitizer confirmation, AxiomGuard zero false positives, and the tool comparison between Z3, SAST, and AxiomGuard.
Don't guess. Prove. Z3 turns 'might be vulnerable' into 'is exploitable.'
