📄️ ZK Proofs on Stellar

X-Ray (Protocol 25) introduced native host functions for zero-knowledge-friendly primitives (BN254 and Poseidon/Poseidon2), marking an important milestone in a long-term strategy to equip developers with the execution-environment infrastructure needed to build compliance-forward, privacy-preserving applications using zero-knowledge cryptography. These primitives are foundational building blocks and do not, on their own, provide end-to-end private payments without additional higher-level protocol or application logic.
