AI Agent
Track Records

The open standard for proving what a trading agent actually earned, without revealing the model. Forty-one numbered requirements, three conformance levels, and one verification procedure anyone may implement.It applies equally to strategies run by people.

VTR-1 gives a three-level view of an agent's track record:

IHonest Execution

The proof recomputes strategy-to-returns on the committed data, charges costs on every transaction, and derives the reported metrics. R-05.

IIDeflated for Trials

The trial ledger is committed before evaluation, N is derived from it, and the anti-overfitting statistics are recomputed in the proof. R-06.

IIISealed & Allocatable

The strategy or model runs on its owner’s machine and is never recoverable from the credential; the holder is bound by key; the record extends forward as a chained track, so bars that arrive after the commitment carry forward evidence. R-08, R-09.

Honest Execution I
Deflated for Trials II
Sealed & Allocatable III

The standard is built on three foundations, none of them trust:

Published statistics

The probabilistic and deflated Sharpe ratios and the CSCV probability of backtest overfitting, implemented as their authors state them in exact fixed-point arithmetic.

Zero-knowledge proof

STARK receipts over a pinned engine image, SHA-256 commitments with domain-separated leaves, and a verifier that runs offline.

Adversarial governance

Sound against a submitter who controls their inputs, and against an issuer who would like to change what a past credential meant.

Published statisticsZero-knowledge proofAdversarial governance

Every agent credential states its own scope, so a claim cannot travel further than its proof:

Data window

The committed data root and the window it covers. Annualisation is bounded by that window and never enters a significance test. R-26, R-35.

Trial ledger

How many candidates were tried, committed before any result, with undetected padding disclosed. R-06, R-24.

Representation

Which strategy representation was used, and a refusal rather than a silent substitution when a strategy cannot be expressed. R-20, R-21.

Requirements fall into two kinds:

Technical

How the proof, the statistics and the commitments are computed, down to the arithmetic.

Governance

How the issuer behaves: what it may claim, what it must publish, and what it must disclose when something breaks.

All 41 requirements, verbatim. Numbers are permanent: a retired requirement keeps its number.
