Today we welcome Jason Teutsch, Chief Scientist and Founder of Truebit, a blockchain-based verification protocol that is making off-chain computation auditable and trustless. At the heart of Truebit is something called the verification game, a cryptoeconomic protocol that lets you compute off-chain and then prove that your computation was correct.

This episode explores the power of onchain attestations, and how blockchain can help us rebuild trust in the digital age, whether that’s verifying AI outputs, proving identity, or enabling decentralized infrastructure for climate data.

In this episode you’ll learn:

• 🧠 What the verification game is, and how blockchain verifiability and tools like onchain attestations are increasing trust in everything from climate change and supply chains to artificial intelligence and identity
• 🤖 How Web3 and crypto primitives can help tackle the “AI black box” problem by providing verifiable computation, helping to ensure that AI outputs can be independently trusted.
• 🌐How DePIN and decentralized computation infrastructure like Truebit unlocks a world where we can move from “just trust us”, to “here’s your proof”

--Key Takeaways--

🔍 Verification is hard but essential. Truebit is pioneering “verification as a service,” using decentralized compute and blockchain to make it easier to independently verify claims, models, and data at scale.

🤖 AI’s black box problem threatens trust. As AI plays a growing role in decisions that impact lives and the planet, blockchain-enabled verification provides a powerful tool for bringing transparency and accountability to machine-generated outputs.

🌎 New asset classes needtrust. Verifiable data unlocks innovations like climate resilience bondsand CAT bonds, which rely on transparent and auditable data to activate payoutsand deliver real-world impact.
