Question 1

What format do miners submit for price predictions?

Accepted Answer

Miners submit an array with a start timestamp, time increment, and multiple price paths (arrays of simulated prices at each increment). For example, a 24-hour forecast with 1,000 paths over 5-minute increments returns 289 price points per path. The exact format is validated by the reference implementation in the repository; a test script (synth/miner/run.py) confirms format correctness before live deployment.

Question 2

How does a miner earn rewards on Synth?

Accepted Answer

Miners earn a share of network emissions proportional to their rolling leaderboard score. After each validator prompt closes, realized prices are compared to submitted paths using CRPS (lower is better). Per-request scores are averaged over a rolling window (5 days for 1-hour, 10 days for 24-hour forecasts) weighted by asset. The final leaderboard score is converted to emission allocations via softmax; the three competitions (Crypto 1h, Crypto 24h, Commodities/Equities 24h) each contribute one-third of total emissions.

Question 3

Can I run multiple miners with different models?

Accepted Answer

Yes. If each miner uses a different model, you can run multiple instances and compare their performance to find the best-performing architecture. However, if you use the same model for all miners on the same asset, their scores will be identical and you will earn the same reward—so running duplicates is not economical. The backtester (synth-lib) can help you benchmark model changes before committing resources.

Question 4

What are the minimum hardware requirements to run a miner?

Accepted Answer

A miner requires at least 2 CPU cores at 2.5 GHz, 16 GB RAM, 12 GB swap, and 10 GB SSD storage. Recommended specs are 4 cores at 3.5 GHz, 25 GB SSD, and 1,000+ IOPS. No GPU is required. Ubuntu 22.04 is the standard OS. Network connectivity must include port 8091 open for inbound validator requests.

Question 5

How long after submitting a prediction do I get a CRPS score?

Accepted Answer

CRPS scores depend on the competition timeframe. For 1-hour forecasts, the first score appears roughly 1–2 hours after submission. For 24-hour forecasts, first scores arrive approximately 25–27 hours after submission. The validator waits for the prediction window to close and real prices to settle before computing CRPS.

Question 6

What happens if my miner misses a prompt or submits in the wrong format?

Accepted Answer

If a prediction is invalid or late, your submission is assigned the 90th-percentile CRPS score (a penalty). Your CRPS for that prompt is capped at that threshold and your smoothed leaderboard score is penalized proportionally. Consistent failures lower your rank and reduce your earnings share. Test your model with the reference script (synth/miner/run.py) and the backtester before going live.
