Simulation of the FHE noise budget + bootstrapping mechanism, paired with the-bootstrapping-tax. Animated noise sawtooth under a decryption ceiling; CKKS vs TFHE scheme toggle contrasts rare-but-slow vs constant-but-cheap bootstrapping. Measured per-model FHE/MPC latencies from arXiv:2604.00169 and arXiv:2504.11604 anchor the mechanism.

Artifact: The Noise Ceiling
An interactive simulation of the FHE noise budget — the mechanism The Bootstrapping Tax hinges on but never depicts. Paired with (and embedded in) the merged article
the-bootstrapping-tax-fhes-fundamental-limit-on-private-ai-inference.What it shows
Every FHE multiplication spends down a finite budget of "levels"; when noise reaches the decryption ceiling, the ciphertext must be bootstrapped — refreshed back down. The stage animates that noise sawtooth as you drag the circuit deeper, and the scheme toggle makes the article's central tradeoff concrete:
The panel reports the live regime (leveled ✓ / bootstrapped ×N), the bootstrap count, and total bootstrapping time, plus measured per-model FHE-vs-MPC latency cards (BERT-Base 149 s / 112 GB · ResNet-50 164 s / 228 GB · BERT-Tiny · ResNet-20 · LogReg) that anchor the mechanism to real numbers. Tap a card to pin its detail (memory, MPC LAN/WAN, throughput gap).
