Methodology

How GenLayer’s Intelligent Oracle resolves Polymarket

A short reference. The landing page has the narrative.

The pipeline

Cumulative since May 6, 2026. Once a day we poll Polymarket and run each market through three gates. Markets land in Direct source, Alternative source, or Currently held.

The gates

Gate 1: on-chain feed filter.

Is the market bound to an on-chain price feed (Chainlink, Pyth)? If yes, the chain has the answer and we step out.

Gate 2: source URL.

Do the resolution criteria name a source URL we can fetch? Markets without one wait for a later agentic-search release. We don’t ship best-effort scraping.

Gate 3: accessibility.

Can a validator reach the named source? If the host blocks validator traffic, we route to a verified alternate with the same fact. If no alternate exists (paywall, login, captcha, pure-consensus subjective market), the market goes to Currently held.

Off-chain step: deeper-page agent.

When a market names a host but not a specific URL, an off-chain agent picks the page and hands the URL to the Intelligent Oracle. The agent runs off-chain; the oracle runs on-chain.

* On the alternate. The alternate is currently agent-chosen, not a hardened whitelist. Anyone publishing a blog post could in principle pass this gate. Reputation and approved-alternate lists are still open product work.

Bradbury

Bradbury is GenLayer’s testnet. The benchmark runs in Studio today (GenLayer’s developer environment); moving it to Bradbury runs each market through real validators and surfaces per-validator on-chain transactions on every per-market detail page.

TLS notary

A TLS notary is a cryptographic receipt that specific bytes came from a specific HTTPS origin at a specific time. It’s the same primitive GenLayer Labs is piloting in its Twitter bounty, applied to any web source. One validator fetches with its own credentials; the proof is portable, and the rest verify it without re-fetching. For this benchmark, it unlocks most of Currently held: paywalled, logged-in, rate-limited, or IP-locked pages. Not shipped yet; on the roadmap alongside hardened alternates and the accuracy backtest.

Open questions

Accuracy backtest. Today the headline is coverage. Next is replaying closed markets through the oracle on Bradbury and publishing per-category accuracy alongside it.
Hardened alternates. The alternate is agent-chosen; a vetted list is still open product work.
Bradbury in production. Moves runs out of Studio and exposes per-validator transactions on the detail pages.
Vertical-specific prompts. The oracle prompt is horizontal today; per-vertical prompts (esports, sports, weather) should sharpen routing and resolution.
