Key Takeaways:

Zero-knowledge proofs (ZKPs): what they are, and why they’re so important in today’s digital landscape
The utility of cryptocurrencies for individuals in poorly governed jurisdictions
The convergence of AI and blockchain, and how ZKPs can verify AI outputs without compromising privacy
The real-world applications of ZK technology, such as private transactions, digital identity verification, and connecting traditional finance with blockchain

Guest Bio: Rob Viglione is the co-founder and CEO of Horizen Labs, the development studio behind several leading Web3 projects, including zkVerify and Horizen.

Rob served in the U.S. Air Force and was deployed to Afghanistan, where he supported Special Operations Task Force intelligence efforts. During this time, he developed an early interest in Bitcoin, recognizing its potential benefits for countries with unstable economies.

Today, Rob’s work focuses on Web3 scalability, blockchain efficiency, and zero-knowledge proofs (ZKPs). With the growing convergence of AI and blockchain, Horizen Labs is also exploring how ZKPs can be used to help verify AI model outputs without compromising privacy.
