Ladder — Global Leaderboard
The Ladder is NMMiner's global leaderboard. It ranks participating miners by the highest share difficulty they have ever produced — your all-time best, not your hashrate, not your share count. One single lucky moment can put a $5 ESP32 above a warehouse of ASICs.
🌐 Public ladder: https://ladder.nmminer.com/
How it works
Every miner that opts in periodically reports its best-ever share difficulty to the Ladder backend. The backend aggregates the entries and exposes the top performers at ladder.nmminer.com.
On-device Ladder page
Every NMMiner with a display has an optional Ladder page that mirrors the leaderboard — see the global top-10 right on your miner. Enable it together with the opt-in below.
Boards without a display can still join the Ladder. Just open NM Monitor → Preferences and toggle the Ladder switch on. Your miner will report normally, even though there is no on-device page to view.
Opt-in (it's off by default)
The Ladder is opt-in. Out of the box NMMiner reports nothing. To join:
- Open NM Monitor → Preferences.
- Toggle Ladder on.
- Save. The on-device Ladder page becomes active (on boards with a screen) and your miner starts reporting.
You can also flip the setting via the HTTP API — see POST /api/setting/preference (LadderEnable: true).
Privacy
NMMiner takes participant privacy seriously:
- No personal info — only the wallet address you mine to is reported, and only the first 4 + last 4 characters of that address are ever shown publicly (
bc1q…ab12). - No IP, no hostname — nothing that could identify you or your network.
- Off by default — you have to consciously enable the feature.
Why join?
- 🏅 Bragging rights — see how lucky your tiny ESP32 has been compared to the world.
- 🤝 Community — the Ladder is the de-facto meetup for ESP32 BTC enthusiasts.
- ✨ The thrill — hitting a high-difficulty share is rare; the Ladder is where those moments get celebrated.
