Questions & Answers

Q: What is Espresso's main goal in the Web3 ecosystem?

Espresso aims to bring low fees and flexible privacy to Web3 applications by developing a high throughput transaction protocol and enabling configurable privacy.

Q: How does Espresso use zero knowledge proofs to solve privacy and scalability issues?

Zero knowledge proofs allow Espresso to prove the validity of transactions without revealing sensitive information, ensuring privacy. Additionally, these proofs can aggregate multiple transactions into a smaller proof, enhancing scalability.

Q: Why is privacy important in the cryptocurrency space?

In the current state, most cryptocurrencies offer pseudonymity rather than true privacy. This means that transaction details are visible to the public, posing privacy risks for users. Privacy is crucial for applications requiring confidentiality, such as enterprise payments or decentralized finance.

Q: What are some potential applications that can be built on top of Espresso?

Developers can leverage Espresso's scalability and configurable privacy to build infrastructure for on-ramps, wallets, and bridges. It also enables additional privacy features for existing DeFi products and opens up possibilities for new innovative applications like privacy-centric games or poker.

Summary

In this episode of the Gray Matter podcast, Seth Rosenberg interviews Charles Liu and Benedict Bunz, part of the founding team of Espresso, a company focused on using zero knowledge proofs to solve privacy and scalability challenges in Web3. They discuss the current state of the blockchain industry, the importance of privacy in cryptocurrency, and how Espresso aims to provide configurable privacy and scalability solutions. They also talk about their backgrounds and how they came together to start Espresso.

Questions & Answers

Q: What is Espresso doing and what is the company's goal?

Espresso aims to bring low fees and flexible privacy to Web3 applications by developing a high throughput transaction protocol that integrates roll-ups and a decentralized proof of safe consensus protocol. Their goal is to scale beyond hundreds of thousands of transactions per second while maintaining decentralization. On the privacy side, they aim to enable configurable privacy, allowing for a spectrum of privacy options depending on the application's needs.

Q: Can you explain what zero knowledge proofs are and how they can be used for privacy and scalability?

Zero knowledge proofs allow you to prove that something is true without revealing why it's true. For example, you can prove that you know the solution to a Sudoku puzzle without showing the solution itself. In the context of privacy in blockchains, zero knowledge proofs can be used to prove that a transaction is valid without revealing sensitive information such as the amounts being transferred or the identities of the sender and receiver. Additionally, zero knowledge proofs can also improve scalability by creating smaller proofs for large statements, allowing for efficient verification.

Q: How does Espresso fit into the concepts of layer one, layer two, and EVM compatibility?

Espresso is a layer one blockchain, meaning it runs its own consensus protocol and is not built on top of another blockchain. However, it aims to be EVM compatible, which means that smart contracts written for Ethereum can also be deployed on Espresso. This compatibility allows developers to build on both Ethereum and Espresso, taking advantage of Espresso's scalability and privacy solutions. Additionally, Espresso plans to create bridges to enable asset transfers between different blockchains, further enhancing interoperability.

Q: Why is privacy important for different use cases in crypto, and what is the current state of privacy in cryptocurrencies?

Privacy is important for various use cases in crypto because existing cryptocurrencies like Bitcoin and Ethereum have transparent ledgers, meaning that every transaction is publicly visible. This lack of privacy can be a limitation for applications such as decentralized finance (DeFi) where over-collateralization is required, as well as for enterprise payments that require privacy. While privacy-focused cryptocurrencies like Monero and Zcash offer full privacy, they have limited options and may not meet the needs of users who want a similar level of privacy as traditional banking transactions. This is where configurable privacy, like what Espresso aims to provide, becomes important.

Q: How did the founders of Espresso meet and decide to work together?

Charles and Benedict met at Stanford University while working on their PhDs in cryptography. They both shared an interest in blockchain and zero knowledge proofs. Charles started organizing a student group called the Blockchain Club, where they had the opportunity to interact with various projects and founders in the blockchain ecosystem. Eventually, Charles, Benedict, Ben Fish, and Jill Gunter came together to start Espresso, united by their vision of building something useful and impactful in the blockchain space.

Q: If someone wants to build on top of Espresso, why would they choose the platform, and what are some interesting applications they should consider?

Developers may choose to build on top of Espresso because it offers a private and scalable layer one blockchain solution. By leveraging Espresso's infrastructure, developers can build applications that require configurable privacy, such as decentralized exchanges with protected identities of traders, or applications that handle real-world asset transfers with privacy. Furthermore, Espresso opens up a design space for new and innovative applications, like zero-knowledge-based games or privacy-enhanced dApps that were previously challenging to build on transparent blockchains.

Q: What did Espresso announce recently, and what are the company's plans for the next six to twelve months?

Espresso recently launched its configurable asset privacy solution called Cape for Ethereum. This solution allows users to bring configurable privacy to existing assets on Ethereum, enabling private asset transfers while still maintaining compliance and auditability. The contracts are open source, and a GUI interface will be released for users to test and interact with the application. In the next six to twelve months, Espresso plans to release its Layer 1 testnet, which will include cape and additional privacy features and scalability solutions.

Takeaways

Espresso is addressing the privacy and scalability challenges in Web3 by leveraging zero knowledge proofs. Their goal is to bring low fees and configurable privacy to Web3 applications through their layer one blockchain solution. They aim to enable privacy without compromising auditability and compliance, allowing for a wide range of applications that require varying privacy levels. The recent launch of their configurable asset privacy solution for Ethereum and future plans for a Layer 1 testnet showcase their commitment to building practical, useful solutions for the blockchain ecosystem.
