A technical tutorial demonstrating how to verify RISC Zero zero-knowledge proofs within Stellar smart contracts using Soroban, enabling complex off-chain computations to be verified on-chain.
This article provides a step-by-step guide for developers to integrate RISC Zero's zero-knowledge virtual machine with Stellar smart contracts. It walks through installing RISC Zero, creating a guest program that runs computations off-chain, generating cryptographic proofs, and then verifying those proofs in a Soroban smart contract deployed on Stellar's testnet. The example demonstrates a simple 'greater than' comparison, but highlights the broader potential: proving complex computations involving megabytes of data in a single transaction, which would be computationally impossible to execute directly on-chain. This integration opens new possibilities for zero-knowledge applications on Stellar.
