▶ The Crucible pitch
Four minutes and fifty-two seconds. Every frame is a live capture.
If the player above does not start, the video is also attached to the
pitch-v1 release.
What it covers
| Beat | Point |
|---|---|
| The problem | Confidential tokens hide what you transfer while proving the transfer was valid — and those two halves are usually built and audited separately, with almost nobody testing whether they agree. |
| The idea | Crucible makes one claim checkable rather than assumed: what a confidential token transaction does locally is what it does on-chain. |
| Architecture | Three layers that compile into each other, with every edge pinned to an immutable revision so a change cannot silently drift underneath another layer. |
| Simulate | Determinism as an enforced property, not a habit — same configuration and seed give the same state, events, commitments and outcomes, bit for bit. |
| Prove | Real Noir circuits compiled to ACIR, real UltraHonk proofs, and a CI step that recompiles the circuits and diffs the committed artifacts so a forgotten re-pin cannot land. |
| Testnet | An UltraHonk verifier contract deployed to Stellar testnet, with proofs verified against it from a checkout that needs no key and no fee. |
| Stress-test | Conformance, adversarial, privacy, regression and performance suites wrapped around the same operations, judged by the real engine rather than a stand-in. |
| Rigour | The documented error-code surface, the determinism contracts, and the limits this project states about itself. |
Why the video exists
A README makes a reader assemble the argument for themselves, in whatever order they happen to read. The pitch makes the argument once, in order, and shows the running system rather than describing it — which is the fastest way to answer the only question that matters first: what is this, and does it actually work?
Nothing in it is a mock-up and nothing in it is a slide about a roadmap. The documentation deployment, the repositories, and the testnet contract are all public, and every claim in the video is reproducible from a checkout.
Regenerating it
The pipeline that produced the video — narration script, live capture,
synthesis, composition, and a probe that asserts the captured pages still
contain what the video claims — is committed in
Crucible-TDA/.github/pitch.
