Is ZK-MPC-FHE-TEE a real creature? | Aztec Blog

In decentralized systems and privacy-sensitive digital environments, three foundational technologies are reshaping how computation and data integrity are managed: client-side zero-knowledge proofs (ZKPs), multi-party computation (MPC), and trusted execution environments (TEEs). These tools offer distinct approaches to achieving privacy, trust minimization, and performance in complex computational tasks.

Key Ideas

Client-Side ZKPs enable individuals to prove data-based claims without revealing the underlying data—ideal for private verification.
MPC allows multiple participants to jointly compute an output while keeping inputs confidential—useful in collaborative, trustless environments.
TEEs operate as secure hardware enclaves that run sensitive computations in isolation—valuable for performance-intensive and secure processing.

The real strength emerges when combining these technologies, such as using TEEs to bootstrap MPC or layering ZKPs over MPC for granular, privacy-preserving proofs.
