The proof has a statement

A zero-knowledge system can prove that private inputs satisfy a public computation. For trading, a circuit might check that an execution record came from an approved venue, used an approved asset, stayed inside a size limit or reconciled with a defined accounting rule. The exact circuit—not the word “ZK”—defines the claim.

What a well-scoped proof may establish

  • A committed record satisfies the encoded circuit constraints
  • A trade used an allowed asset, venue or function
  • A value stayed within a predefined range
  • Inputs and outputs reconcile under a defined accounting rule
  • The verifier accepted the proof for a specific circuit and public input

What it does not establish by itself

  • The strategy will be profitable
  • The underlying market data was complete, unbiased or timely
  • The approved venue is solvent or safe
  • The private strategy is sensible
  • Every relevant action was included in the proved dataset
  • The smart contracts, adapters or surrounding application have no vulnerabilities
  • The result is suitable for a particular user
Verified claim = circuit + committed inputs + public inputs + verifier result

The coverage question

A valid proof can still cover an incomplete claim. Readers need to know which trades, venues, periods, accounts and accounting events enter the proof system. Coverage should be distinguished from validity: validity asks whether the proof verifies; coverage asks whether the proved claim represents the thing a user believes it represents.

Five questions for a proof-backed product

  1. What exact public statement does the circuit verify?
  2. Who produces and commits the underlying records?
  3. What data or activity lies outside the proof boundary?
  4. Which circuit version and verification contract are active?
  5. Can an external user reproduce the verification path?

Knidos relationship

Knidos, the publisher’s product, describes ZK-verifiable execution and accounting checks. This publication does not treat ownership as independent validation. Product-specific claims must link to the circuit, verifier, coverage documentation and audit evidence appropriate to the exact statement.
