PROVEN PROCESS
Our Formal Verification Methodology
We apply rigorous, mathematical proof techniques to verify the safety and liveness properties of your consensus mechanism. This eliminates critical vulnerabilities before deployment, ensuring your network operates as intended under all conditions.
01
Specification & Property Definition
We translate your consensus protocol's intended behavior into formal, machine-readable specifications. This includes defining critical safety properties (e.g., no double-spend) and liveness properties (e.g., eventual transaction inclusion).

02
Model Construction & Abstraction
We build a precise mathematical model of your protocol, abstracting away implementation details to focus on core logic. This model serves as the single source of truth for automated theorem proving and model checking.

03
Automated Theorem Proving
Using tools like Isabelle/HOL or Coq, we construct mathematical proofs that your model satisfies all defined properties. This provides the highest level of assurance, proving correctness for all possible system states and inputs.

Code-Level Verification
We bridge the gap between the formal model and the actual implementation. Using tools like the K Framework or VeriSol, we verify that the production code (Solidity, Rust, Go) correctly implements the proven model.

STRATEGIC ADVANTAGE
Why Founders and CTOs Choose Formal Verification
Beyond standard audits, formal verification provides mathematical proof of correctness for your protocol's core logic, eliminating entire categories of risk and building unshakable trust with users and investors.
01
Mathematical Proof of Correctness
We use automated theorem provers like Coq and K-framework to generate mathematical proofs that your consensus mechanism's state transitions and invariants are logically sound, eliminating speculation from security.

A Technical Comparison for CTOs
Formal Verification vs. Traditional Security Reviews
Choosing the right security methodology for your consensus mechanism is critical. This table compares the depth, guarantees, and resource requirements of Formal Verification against conventional audits.
| Security Aspect | Traditional Security Review | Formal Verification (Chainscore) |
|---|---|---|
Verification Method | Manual code review & heuristic testing | Mathematical proof of correctness |
Security Guarantee | Probabilistic (finds bugs) | Deterministic (proves absence of specific bugs) |
Coverage Scope | Sample-based; depends on test cases | Exhaustive for specified properties |
Time to Completion | 2-4 weeks for initial report | 4-8 weeks for full property specification & proof |
Cost Range | $15K - $50K (one-time) | $75K - $200K+ (project-based) |
Ideal For | General smart contract logic, post-development | Core consensus logic, protocol invariants, pre-launch |
Output | Vulnerability report with severity ratings | Formal proof document & machine-verifiable specifications |
Team Requirement | Senior security auditors | PhD-level researchers & formal methods engineers |
Ongoing Value | Snapshot in time; requires re-audits for changes | Reusable specifications for future protocol upgrades |
