The platform for verified software.
Compile, certify, publish. The standard format for software that provably works.

[01] · THE PROBLEM
We build skyscrapers with blueprints.
We build software with hope.
A bridge engineer knows exactly how much weight each beam can hold. A chip designer knows exactly what signal each gate produces. But a software engineer? They write code, run some tests, cross their fingers, and ship.
Verified Parts
Like tested beams in a bridge. Each part is mathematically proven correct before it's ever used.
Composition Laws
Parts connect through algebra, not duct tape. If Part A works and Part B works, A+B is guaranteed to work.
Automatic Check
The compiler verifies every connection. If the circuit doesn't close, the program simply won't compile.
Compound Interest
A certified component never needs rewriting. The more that exist, the less anyone needs to build from scratch.
[02] · THE BLUEPRINT
Before you build, you draw the blueprint.
PCD is the standard format for verified software. It describes WHAT your program computes — not HOW. Language-agnostic. Mathematically verifiable. Compiles to any target.
“One blueprint. Any material.”
Output — Rust
fn hello() -> i32 {
let msg = "Hello, verified world!";
let n = msg.len();
io::stdout().write_all(msg.as_bytes()).unwrap();
0 // Φ_c = 1 — circuit closed
}Not a language
PCD is a format, like PDF for documents or SVG for graphics. It describes computation, not syntax.
Verified operations
Every PCD program is built from formally verified operations. Core operations proven in Coq, plus contract-based extended set.
Verified by design
If the blueprint doesn't close as a circuit (Φc≠ 1), it simply won't compile. The math is the guarantee.
“PCD is to code what architectural blueprints are to buildings. You describe once. You build in any material.”

[04] · THE PLATFORM
Where verified software lives.
Publish PCD blueprints. Discover certified circuits. Compose and ship. Every component with a mathematical proof.
Your circuits, organized by project. Build, test, and recompose with real-time certification status.
A growing catalog of pre-certified circuits. Search, explore, and implement — never rewrite what's already proven.
Drag, connect, compose. Every connection verified automatically through EVA algebra.
Live proof embedded in your README. If the code changes one byte, the badge invalidates instantly.
[05] · THE FOUNDATION
One compiler. Every guarantee.
Write once in PCD, compile to any target, and ship with mathematical proof that your code is correct. No runtime surprises — every operation verified before it runs.
Compile
Write PCD once, emit verified binaries to any target. One blueprint, every language.
Verify
Mathematical proof in Coq — not just tests. Certainty, not confidence intervals.
Lift
Import existing code from any mainstream language into PCD. No manual rewriting required.
Certify
Φc = 1 means zero uncertainty — every operation closed, every path verified.

[06] · WORKFLOW
Three steps to verified software.
Connect Your Repo
Link any GitHub repository. On every push, BRIK-64 auto-lifts your code into PCD blueprints.
- GitHub App 1-click install
- Auto-lift on push
- PR comments with certification
- Monorepo support
Certify Reusable Logic
Every extracted circuit is verified by the TCE. If Φc= 1, it's mathematically guaranteed.
- Automatic TCE verification
- Φc = 1 certification badge
- Domain constraint validation
- Two-tier: CORE + CONTRACT
Publish to Registry
Ship certified PCD packages to the public registry. Every package carries an immutable proof.
- Public & private registries
- Semantic versioning
- Dependency resolution
- Searchable marketplace
[07] · INTEGRATIONS
PCD is where your logic lives.
GitHub is where your code lives.
BRIK-64 connects both.
The Full Workflow
Push to GitHub
Your team pushes code as usual. No workflow changes required.
Lift to PCD
BRIK-64 automatically lifts your code into a PCD blueprint — a language-agnostic, verified representation.
Certify
TCE verifies every circuit. Φc = 1, and your PR gets a certification comment automatically.
Build to any target
Emit verified code to Rust, JavaScript, Python, or any supported target from the same blueprint.

[10] · AI-NATIVE
The first language designed for AI.
PCD has a finite, learnable set of operations. An AI model can learn the entire language in minutes and generate certified code with mathematical guarantees. When an AI generates PCD, the compiler automatically certifies it. The math is the trust.
