The four primitives behind programmable privacy: TEE, FHE, MPC and ZK
Quote160 words
Compares TEE, FHE, MPC and ZK by trust model and cost, and argues the future is hybrid. The real unlock is institutional DeFi without MEV, private AI inference and verifiable agents, not private payments.
Key claims
TEE overhead 5-15%
FHE up to 1000x+ slower than plaintext but improving ~8x annually
STARKs offer quantum resistance

Quick breakdown of the core technologies enabling confidential computing:
โค TEE (Trusted Execution Environments)
Hardware enclaves that isolate computation. Near-native performance (5-15% overhead), but you're trusting the hardware/chip manufacturer.
โค FHE (Fully Homomorphic Encryption)
Compute on encrypted data without decrypting. Math-only trust, quantum-resistant, but still up to 1000x+ slower than plaintext operations today. Improving ~8x annually tho.
โค MPC (Multi-Party Computation)
Split secrets across parties so no single node sees the full picture. Sweet spot for threshold custody and collaborative compute.
โค ZK (Zero-Knowledge Proofs)
Prove something without revealing the underlying data. SNARKs for succinct/compact proofs, STARKs for quantum resistance.
However, no single primitive solves everything.
The future is hybrid: MPC+TEE for distributed trust with hardware acceleration, ZK+TEE for verifiable confidential compute, FHE+ZK for provable encrypted computation.
The real unlock isn't private payments (e.g. Zcash).
It's institutional DeFi without MEV, AI inference on sensitive data, and autonomous agents with verifiable behavior.

2025 was the breakout year for privacy, led by Zcash. Imho, this was just the beginning though. Programmable privacy is going to be a leading narrative in 2026. Study ZK (Aztec). Study MPC (Arcium). Study FHE (Zama). Study TEE (Phala). t.co/Ac16RIAWgX
