Where a commitment earns its keep.
Any protocol where one party must bind to a choice without yet announcing it — the fairness core behind the hottest 2026 narratives, from anti-MEV ordering to verifiable AI. Each shape below comes with the exact code that implements it.

Anti-MEV & fair ordering
Front-runners cannot react to orders they cannot yet see.
Order intents commit during a sealed window, then reveal for matching. Because a commitment leaks nothing, a searcher cannot front-run or sandwich an order until it is revealed — and by then the ordering is fixed. Commit-reveal removes the timing edge that MEV extraction depends on.

Verifiable on-chain AI
Independent agents answer without copying each other.
In networks where independent agents (DFPN-style inference or forecasting nodes) submit answers, the risk is that a lazy operator copies a peer instead of computing. Each agent commits to its output first and reveals only after the window closes. The optional Schnorr ZKP then lets an agent prove its reveal matches its commitment without re-broadcasting the payload.

Sealed-bid auctions
No bidder can peek at another’s bid before the deadline.
Bidders commit to their bids during a sealed window, then reveal after it closes. Because a commitment leaks nothing about the value, no late bidder — and not even the auctioneer — can react to earlier bids.

Fair-launch randomness
Uniform, unmanipulable randomness with no trusted oracle.
Multiple parties commit to random seeds, then reveal them. The final randomness is a hash of all revealed seeds. As long as one participant is honest and unpredictable, the result is uniform and no single party can steer it.

Hidden ballots & market resolution
Vote or resolve in secret, prove the reveal is honest.
Voters commit to a choice during voting, then reveal to tally. The same shape resolves prediction markets: a resolver commits to an outcome before it is public, removing the last-look advantage. With the optional Schnorr ZKP, a voter or resolver can prove their reveal matches their commitment without re-publishing it for everyone to inspect during verification.

Teaching cryptography
A readable, zero-dependency reference you can teach from.
The whole library is small enough to read top to bottom in an afternoon. secp256k1 is the textbook affine implementation; the Schnorr proof is the textbook Fiat–Shamir transformation. Nothing is hidden behind a native binding.
