Question 1

How does face identity preservation work in the image generation process?

Accepted Answer

Miners use AdaFace similarity scoring (minimum 0.4 threshold) to validate that generated variations represent the same person before submitting to validators. The grading API performs a secondary identity check (ada_sim ≥ 0.6 for basic pass), and validators require submissions above the quality threshold to earn rewards. Identity preservation is enforced at both the miner and validator stages.

Question 2

What image transformation types can miners generate?

Accepted Answer

Miners generate five core variation types: pose_edit (head rotation ±15° to >±45°), lighting_edit (subtle to dramatic shadows), expression_edit (smile, serious, surprised, laughing), background_edit (color shift to dramatic environment change), and screen_replay (device screen simulation with moiré/glare/keystone distortion). Validators can also request combined variations (e.g., lighting + pose) and accessories on background edits.

Question 3

How are miners rewarded and what happens to poor-quality submissions?

Accepted Answer

Miners earn rewards based on a blended score: 10% image-quality (KAV) from the grading API and 90% reputation (UAV) from the server. Top 50 miners receive exponential-decay ranking rewards. Poor submissions score 0–2 (corrupted, duplicate, or identity not preserved); acceptable submissions score 3–5 (partial to exact match). Submission failures don't earn rewards but keep the miner active on-chain.

Question 4

What hardware does a miner need to run face image generation?

Accepted Answer

Miners require a GPU with at least 8GB VRAM (NVIDIA CUDA or Apple Silicon MPS), 8–12 CPU cores, 16–32GB RAM, and 80–150GB free disk space. FLUX.2-klein is the baseline model (~8GB VRAM); higher-end GPUs (A100, RTX 4090) and alternative models (Qwen, PuLID) enable better quality but require more VRAM.

Question 5

How does the drand timelock encryption protect submitted images?

Accepted Answer

Miners encrypt images using drand timelock (set for ~40 minutes after submission). Validators receive only encrypted S3 references until the drand round reveals, preventing validators from grading before all miners have submitted. This creates a level playing field where no miner can adjust their strategy based on peers' submissions.

Question 6

Can validators run on CPU without a GPU?

Accepted Answer

Yes. Validators are CPU + network workloads only. They do not run diffusion models or generate images. Validators require 2–4 cores minimum (4–8 cores recommended), 8–16GB RAM, and stable outbound HTTPS access to the Yanez API and grading API. Typical forward passes take ~1 hour (20 min mining query, 20 min wait for drand reveal, 20 min grading).
