<p class="fair"><b>Graphics cards only.</b> A new mining program every hour, so no chip is built for it. 80% of every block to the card that finds it, 20% to the cards that prove it. No premine, no stake, no fee to any team. Every number above has a row in <a href="/miners">the bench table</a>.</p>
<p class="fair">Your card against the strongest chip we can price. Igneum remains competitive on accessible commodity GPUs even when specialised mining hardware is assumed to exist, remain compatible and seek profit; its security does not rely on identifying that hardware or retiring it through emergency changes. Class v6 adopts the 64-register window and retains it across every rotation. Current modelling estimates a 1.5x to 3.1x energy-efficiency advantage for the specialised designs assessed as complete machines against the GPU tier, from a board on commodity DRAM at 1.5x to an SRAM-store die at 3.1x (1.5x to 2.3x on the GPU's own node). The long-program and select-tree proposals were rejected. Economic resistance depends on development cost, deployment economics and productive hardware lifetime; family transitions receive an obsolescence benefit only where a loss of competitiveness is demonstrated; programmable multi-epoch designs are included in the assessment. The GPU side is measured: the RTX 5090 at its 1,300 MHz lock, 2.33 microjoules per hash on class v4, the window’s cost within 5 percent per load (8 October 2026); the chip’s core is placed and routed on ASAP7 with SRAM macros and scaled on claimed node factors; its memory and the rest of the machine (controller, host share, PSU, VRM, cooling) are modelled; no chip is measured and the chip’s hardware cost is approximate within 2x (MODELLED). Under class v5 the chip is wrong on every item because the dataset is the chain’s own state (designed). <a href="/litepaper#chip-model">Every number with its label, the harness and the scoring rules</a>.</p>

<div><div class="eyebrow"><span class="line"></span>Before you start</div><h2>The questions worth asking.</h2></div>
</div>
<div class="faq">
<details><summary>Does this website use my GPU to mine?</summary><p>No. The pictures on the home page are drawn, not mined. Mining happens only in the app you install, and only when you press Start.</p></details>
<details><summary>Does my card mine and prove?</summary><p>Every card mines. NVIDIA proves; AMD and Apple mine. Mining and proving together needs a 16 GB NVIDIA card at the proposed 5.5 GiB dataset (the costed alternative; the first step sits at 4 GiB, where the miner holds less and the rule is not yet measured) (the miner about 6.1 GiB, a compressed proof about 7.5 GiB at its peak); an 8 GB or 12 GB card time-shares, the app pausing the miner for the proof; on the stock server the full shard needs 24 GB and a 32 GB card does both at once (measured, 6 and 8 October 2026). Apple silicon proves on the CPU, slowly. The Prove page of the app says in one sentence what your card can do.</p></details>
<details><summary>Is the devnet paying real money?</summary><p>No. Devnet coins have no value and the chain may reset. The app’s pounds row reads 0.00 on devnet and says why. The Igneum 2.0 devnet is the network today. Mainnet has not started.</p></details>
<details id="fee-faq"><summary>Is there a fee?</summary><p>Not in the protocol: no dev fund, no fee to any team. The app takes an optional 1% software fee, the norm for GPU miners, and one flag turns it off. <a href="#fee">The fee, in full view.</a></p></details>
<details><summary>Can I run it on a rig or in a pool?</summary><p>The Linux and HiveOS tarball is above, with the flight sheet. Today every machine mines solo on its own keys, and a card runs several.</p></details>
<details><summary>Where do the numbers on this page come from?</summary><p>Every rate has a row in <a href="/miners">the bench table</a> and an entry in the measurement record in the repository (docs/bench-log.md) with the command and the hardware. Nothing here is estimated earnings.</p></details>
