The app you mine with.
Your rate, what it costs a day, and the chain drawn live with your own blocks ringed. One window, four pages, every card one row.
The number, then the chain
One big number: your hash rate. Beside it, watts, hashes per watt, and what the electricity costs a day at your price. Then the chain itself, as it grows.
- Your blocks, ringedEvery block the network makes, one lane per miner, yours marked. A locked checkpoint rings the blocks it covers.
- The node, one lineSynced, peers, blocks, read N seconds ago. Details opens the chain numbers in place.
- ActivityBlocks found, tunes finished, updates installed, with the time of each.
Every card, tuned by Ember
One row per card: rate, watts, hashes per watt, pounds a day, temperature, a Tune button and a switch. Ember Tune walks each card through its power steps and keeps the point with the most hashes per watt.
- Three goalsEfficiency, Balanced, Maximum. Set once for every card, or per card under its chevron.
- Under the chevronThe power cap, the goal, the last tune’s curve of rate against watts, how many miners the card runs as.
- Power control, one approvalSetting an NVIDIA cap needs administrator rights on Windows. The app asks once; every cap after that is set with no prompt.

Ember run 6 on the three-card Windows rig. The pounds are arithmetic from the saved watts at 28p per kWh; the app uses your price. The log.
The chain on your screen
This is the live devnet, drawn by the same code the app ships. Every square is a real block; a lane per miner; a ring where a checkpoint locked. In the app, your own lane is marked.
120 s of blocks on screen. Hover or tap a block for its hash, miner and proof state. Ctrl or cmd and scroll, a pinch, or a click into the scene zooms the window.
Money first
What you made, where it goes. IGN from blocks and from proofs, the electricity at your price, and the address every block pays.
- The dev fee switch1 block in 100 pays the people who make this app. The network itself takes nothing. The switch turns it off.
- An address made on this machineCopy it, change it, or show the key. Nothing leaves the machine unless you copy it.
- Open the walletYour balance is in the wallet, which imports the miner’s key with one click.
One switch. The same card proves.
Every block is turned into a short proof, in pieces called shards. Your cards prove the shards the chain assigns to them and earn IGN for each one.
- One sentence per cardWhat it can prove and how. A 24 GB NVIDIA card proves the full shard; a 32 GB card mines and proves.
- One line of countsAssigned, proven, paid, IGN. Details holds the verifier, the program id and the segments.
Plain rows, one sentence each
- Electricity pricePence per kWh, set once. Every pound figure in the app uses it.
- Start at loginOpens when you sign in and keeps mining in the background.
- Updates by itselfSigned, downloaded in the background, installed at a quiet moment, never mid-program.
- LogsCopy the last lines the node and the miner wrote, for a support message.
Under 720 px, the rail becomes a tab bar
The same window on a narrow screen: the big button, the number, the chain, then the tabs.
Built to be left alone
Measured against a worker that misbehaves on command, 4 October 2026: recoveries in seconds. The log.
- Hourly program, no pauseThe next program compiles in the background and swaps at the boundary: 0.01 ms on Metal, 0.00 ms on CUDA, 0 rejected blocks.
- Watchdog per cardNo status line for 90 s, or a rate of 0 for 60 s while synced: the miner restarts once. Again inside five minutes, the card is marked faulted and the others keep mining. Measured: 91.0 s back to mining.
- Watchdog per nodeA node silent for 120 s is restarted by the app. Measured: silent node to mining again in 160.0 s.
- Restart in orderMiners first, then the node, on quit and on update. What crashes comes back.
- Clock checkOver 5 s out, a warning; over 10 s, Start is blocked and a Sync clock button appears. A slow clock once kept a node silently dead for 12 minutes.
- Signed, over the airAn Ed25519 key compiled into the app checks the manifest before the app reads it. If the new version fails to start twice, the previous one comes back by itself.
