The Toolkit for Zero Knowledge Proofs for Blockchains
The podcast episode features Jacob Abrahamart from the Zachertees team discussing their toolkit for zero knowledge proofs. Jacob shares his background, how he got into working on blockchain, and his research on scalability and privacy problems in blockchains. They discuss off-chain computations and the challenge of integrating them securely with blockchains. They explore the use of zero knowledge proofs as a mechanism to ensure correctness in off-chain computations. Jacob explains the concept of rank one constraint systems and their role in generating proofs. He also touches on the potential of integrating Bulletproofs, enclaves, and secure multi-party computations in off-chain computations. The episode concludes with an overview of the Socrates project and its compatibility with different blockchain protocols.
Choosing the Right Approach for Off-chain Computations
The episode delves into different approaches for off-chain computations, highlighting their trade-offs and potential use cases. They discuss enclave-based systems that rely on trusted execution environments for secure off-chain computations. They explore the concept of secure multi-party computations, where computations are distributed across a network of nodes without exposing the underlying data. The episode also discusses incentive-based off-chain computations, where economic incentives drive participant behavior. They analyze the security assumptions, on-chain verification complexity, and efficiency of these approaches. They highlight the need for customized off-chain patterns based on specific use cases.
Socrates: A Toolkit for Zero Knowledge Proofs on Ethereum
The podcast introduces the Socrates toolkit, a set of tools and a domain-specific language that enables developers to construct zero knowledge proofs and verify them on the Ethereum blockchain. Jacob explains the process of specifying computations in the Socrates language and the compilation steps that generate provable abstractions. He discusses the concept of rank one constraint systems and their translation to quadratic arithmetic programs using libraries like Lipsnark. The episode also touches on the challenge of trusted setup in zero knowledge proofs and the potential integration of alternative proving systems like Bulletproofs. Jacob highlights the role of Socrates in simplifying the construction and verification of zero knowledge proofs for smart contract developers.
The Intersection of Industry and Academia in Blockchain
The episode explores the growing collaboration between industry and academia in the blockchain space. They discuss the evolving financing models and research collaborations in the blockchain industry. Jacob emphasizes the mutual benefits for both industry and academia, as blockchain projects require cutting-edge research and academic contributions gain practical real-world applications. They highlight the importance of naming conventions in making academic concepts more accessible in the industry. The episode concludes with Jacob's recommendations for learning about zero knowledge proofs, including reading academic papers, studying low-level libraries like Lipsnark, and exploring domain-specific languages like Socrates.
In this episode, we had a chance to speak with Jacob Eberhardt about his work on Zokrates and the Zero Knowledge Proof Toolkit. Zokrates is a programming language & toolbox for zkSNARKS on Ethereum
