Joined December 2018
The time has come to build the next generation of the optimistic oracle. We’re working with our friends at @Polymarket and @eigenlayer to do so. The new oracle will be built in public.

UMA’s mission remains:. Be the canonical source of truth that blockchain applications use to verify real-world data. The OO is proving it is up to the task. Let’s keep building.

What’s next?. UMA is aligning around one big question:. Can we bring scalable, AI-assisted truth onchain?. We believe the answer is yes. And we’re positioned better than ever to lead that future.

Although still early, the @OOTruthBot is already promising. We're also building LLM bots that assist with everything from summarizing Vote Contribution threads to surfacing early red flags. Eventually, they’ll help aggregate market interpretations and reduce human bias.

And we’re not stopping there. We have embraced AI as a core component to the future of the OO. Why? Because LLMs can:. • Propose data for ~$0.005.• Dispute in seconds.• Show up every time. AI is simply faster, cheaper, and more reliable.

And it’s getting cheaper. The cost per OO request is dropping as usage scales. This means UMA can handle more volume, more proposals, and more dispute load without increasing costs.

Even with rising proposal volume, dispute rates remain low. That’s a strong signal. The OO isn’t just scaling. It’s scaling well. Most resolutions go undisputed, and when they are disputed, the process works as designed.

The OO is doing numbers. We’re seeing ~7,000 proposals/month, powering over $1B in betting volume. Polymarket’s growth = OO’s growth. And it's accelerating. More users. More volume. More trust to earn.
