Overview

0.3.22, rendered from the app’s recorded states, 7 October 2026: a mixed rig of an RTX 5090, an RX 9070 XT, an Arc B580 and an integrated UHD 770. The 5090 and the 9070 XT carry measured rates; the Arc’s 15.2 MH/s is the plan’s expectation until the measurement on the team's three-card Windows rig lands. Electricity at 26.32p per kWh, the UK typical price.

01 · Overview

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.

The Cards page of 0.3.22: Ember Tune with the Efficiency, Balanced and Maximum goals; one row per card with its vendor's mark, its series line, its rate, IGN a day, watts, hashes per watt, cost a day and temperature: an RTX 5090 at 122 MH/s and 291 W, an RX 9070 XT at 18.9 MH/s and 198 W, an Arc B580 at 15.2 MH/s, an integrated UHD 770 off — 0.3.22, rendered from the app’s recorded states, 7 October 2026: a mixed rig of an RTX 5090, an RX 9070 XT, an Arc B580 and an integrated UHD 770. The 5090 and the 9070 XT carry measured rates; the Arc’s 15.2 MH/s is the plan’s expectation until the measurement on the team's three-card Windows rig lands. Each row carries its vendor’s mark and its series line.

02 · Cards

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 Tune, measured 6 Oct 2026	Untuned	Tuned	Saved
RTX 5090	311.0 W · 127.9 MH/s · 0.411 MH/W	226.8 W · 127.7 MH/s · 0.563 MH/W	84 W, £0.56 a day at 28p/kWh
RTX 4070	106.0 W · 28.72 MH/s · 0.271 MH/W	75.6 W · 28.78 MH/s · 0.381 MH/W	30 W, £0.20 a day at 28p/kWh

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.

03 · The chain, live

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.

04 · Earnings

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.

Apple silicon proves on the CPU, slowly; a 12 GB NVIDIA card is the line for proving beside the miner.

05 · Prove

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.

08 · It keeps mining

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.
