Questions & Answers

Q: What is the main advantage of zero knowledge cryptography in regulated stable coins?

Zero knowledge cryptography allows for the replication of the experience of cash in a digital sense, providing privacy and security in transactions without revealing the underlying details.

Q: How can zero knowledge proofs be used in gaming applications?

Zero knowledge proofs can enable hidden information games, where players can maintain privacy about their strategies or in-game assets. This opens up new possibilities for decentralized and player-driven gaming experiences.

Q: What are some challenges associated with zero knowledge cryptography?

Challenges include the performance overhead of generating proofs, the lack of tooling for developers, and the need for data availability to ensure proofs can be verified. These challenges are being addressed, but optimization and adoption are ongoing efforts.

Q: How does zero knowledge cryptography enhance self-sovereign identity?

Zero knowledge proofs can be used to authenticate an individual without revealing their personal information, such as a passport. This allows for secure digital identity verification while maintaining privacy.

Summary & Key Takeaways

• Zero knowledge cryptography is a game-changing technology that allows for proving something without disclosing why it's true.

• It has applications in various fields, including regulated stable coins, proof of solvency, self-sovereign identity, secure voting, gaming, and more.
