Opinion,
not prediction

Prediction markets ask “what will happen?” - b⁴ asks “what do most people believe?” Opinions resolve on crowd consensus, not real-world outcomes. Your edge isn't knowing the future, it's knowing the crowd.

OLD WAY

Prediction Markets

Stake on whether something actually happens. Requires oracles, real-world event verification, and waiting for outcomes. Resolution is binary and objective.

—Resolves on real-world events
—Needs trusted oracles
—Wait days, weeks, or months
b⁴ WAY

Opinion Economy

Trade on what the majority believes. Polls resolve via crowd consensus in 24 hours. No oracles needed — the crowd is the oracle.

✓Resolves on crowd belief
✓No oracles, the crowd decides
✓24-hour resolution cycles

Human-only
conviction

No bots. No agents. Just real humans expressing real conviction. b⁴ runs exclusively on mobile because the phone in your hand is the strongest identity primitive that exists: secure hardware, biometrics, and one device per human.

✓One human, one vote: Your wallet is bound to your physical device — and the pairing survives reinstalls. One device, one wallet, one vote. Bot farms need not apply.
✓Passkeys, not seed phrases: Biometric signing with hardware-backed keys. There's nothing to phish, nothing to copy-paste, nothing to hand to a script.
✓Screened, allowlisted relay: Every vote flows through our gasless relay, which only co-signs for verified devices on registered wallets.
✓No browser, no automation: There's deliberately no web app. No extensions, no headless browsers, no API to farm — the feed only exists in your hand.

Time
will tell

Opinion markets shouldn't behave like prediction markets. You shouldn't be able to sell shares of your opinion, and why should you be able to hedge your own opinion? Time-weighted stakes measure real conviction. Committing while the outcome is still uncertain is worth more than piling on when it's obvious.

1Up to 2× money weight for early conviction: Money weight decays with time and volume. Vote early for more piece of the pie.
2Late stakers reward early voters: As time runs out, fees go up. Excess late fees enter a conviction pool that brings even more value to the winning side.
3Downside capped at ~12%: Exit your position at any time before close. Losing side exit keeps ~88% of their stake.
4Conviction is the product: Early conviction earns double, late certainty earns nothing. That asymmetry is the whole point.
