Servicifying zk-SNARKs Execution for Verifiable Off-chain Computations

Abstract

Zk-SNARKs help scale blockchains with Verifiable Off-chain Computations (VOC). zk-SNARK DSL toolkits are key when designing arithmetic circuits but fall short of automating the subsequent proof-generation step in an automated manner. We emphasize the need for portability, interoperability, and manageability in VOC-based solutions and introduce a Proving Service that is designed to provide a scalable and reusable solution for generating zk-SNARK proofs leveraging clouds.
