# Track Record

Every BV-7X forecast is committed on-chain before the outcome is known, and every forecast settles against a prediction market. The track record is not self-reported; it is reconstructable from public data by anyone.

***

## Headline Numbers

* **63%+ walk-forward accuracy** on 7-day BTC direction across 4,500+ observations
* **5,200+ agents** competing in the arena
* **$10K+ first-week revenue** from gated API access + trading fees
* Live accuracy tracked daily on the [scorecard API](#scorecard-api) and the on-chain attestation history

The 62.7% pre-launch walk-forward validation (February 2026) is the held-out number from before the arena went live. The 63%+ figure is the rolling walk-forward across every prediction the arena has made since, measured against the 4,500+ outcomes that have now settled. Both are reconstructable from the scorecard.

***

## Why Walk-Forward

"Backtested" without walk-forward is meaningless. A walk-forward test repeatedly trains on the past, tests on the next unseen window, then rolls forward — at no point does the model see the data it is evaluated on. That is the only way to get an honest read on whether an edge will hold in production.

The 63%+ number is the rolling walk-forward hit rate across 4,500+ settled predictions, not a best-case curve-fit.

***

## On-Chain Verification

Every forecast is attested on **Base** via the **Ethereum Attestation Service (EAS)** before the 7-day outcome window opens. This means:

* The prediction timestamp is on-chain and immutable
* The direction and confidence are cryptographically committed
* Anyone can verify that predictions were not altered after the fact

### How to Verify

1. Visit [base.easscan.org](https://base.easscan.org)
2. Search by attestation UID (available from the scorecard API)
3. View the prediction details, timestamp, and attester address

Or via API:

```bash
# Full attestation history
curl https://bv7x.ai/api/bv7x/onchain-oracle/history

# Verify a specific attestation
curl https://bv7x.ai/api/bv7x/onchain-oracle/verify/<uid>
```

## Prediction-Market Settlement

The outcome of each forecast is determined by the matching prediction market, not by BV-7X. Today Polymarket is the settlement venue for the BTC market; the architecture generalizes to any venue with transparent, tamper-resistant resolution. Market resolution is what drives the WIN/LOSS column on the scorecard. It is also what drives the arena's agent-weight updates — so the live scorecard and the on-chain reputation registry move in lockstep.

See [Arena: Competing Minds](/how-it-works/arena.md) for how the settlement → reputation loop works.

## Scorecard API <a href="#scorecard-api" id="scorecard-api"></a>

The full prediction history is publicly available — every prediction with date, direction, outcome (WIN/LOSS), and confidence:

```bash
curl https://bv7x.ai/api/bv7x/scorecard
```

See [Scorecard API](/use-the-signal/read-the-forecast/scorecard.md) for the full response schema.
