igneum-labs 559494e8ac site-redesign: the full-site redesign on our content, 22 pages served
The package's design system, layouts and interactions on our tokens and self-hosted fonts (site/site.css section 10),
our facts, numbers, records and live services on every page. The home page: the GPU hero (site/hero-scene.js, continuous
while in view, labelled as drawn), the live DAG panel on scenes/feed.js and live-dag.js 2.0.2, three reasons, the
economics split, the download row with the OS marks, the ledger line. The miner page: the download layout, platform
tabs stamped from the live download index with sha256, the steps, the card table, the fee section (the one source of
/dev-fee), the FAQ. The wallet page in the package's wallet-hero layout, the window slot ready for the wallet redesign.
The secondary pages rendered by the build from one source each: /claims and /randomx from the litepaper's sections,
/dev-fee from the miner's fee section, /provenance from docs/provenance.md through the scrub, /journey from
journey.json; /benchmarks rewrites to /miners, /connect redirects to /metamask. The generated pages (bench, bench
table, ledger) restyled onto the page hero and the docs layout with a section filter. The footer's secondary links point
at the real pages. The copy pass on every served page (docs/plans/site-copy-pass.md). The package's data tests and the
hero loop test in the gate (tools/site-redesign). No sample data is served; the package's review chrome is not.

<div class="derived"><p>RandomX has kept chips off Monero since 2019 (approximate) by making the mining program random, so the hardware that runs it well is the hardware everyone already owns. The one chip announced against it, Bitmain’s Antminer X9 (pre-orders from 26 December 2025 at 1 MH/s and 2,472 W, about USD 5,600), was withdrawn in mid-May 2026 before any unit shipped; RandomX 2.0 shipped on 25 March 2026 (monero-project/monero issue 10270). Igneum takes the same principle to graphics cards and adds what RandomX never had.</p>

Every number above is measured and logged with the commands that produced it. The specification, reference hash, test vectors and simulators are public now (github.com/igneum-network/spec).

<p>Measured so far: the same hourly program, generated on an Apple M5 Max, compiled by Apple's Metal and NVIDIA's CUDA on an RTX 5090, produced identical hashes on both, 192 of 192 across two programs. On a 1 GB dataset the 5090 ran at about 228 million hashes a second and the Mac at about 45 million, both bound by random memory access rather than arithmetic. Those are prototype figures, not mining rates. The first prototype dataset was a closed-form function, and a miner could compute items instead of loading them: measured 111x faster that way on the Mac. The 256 MB cache construction replaced it on 3 October 2026. With the cache, computing items on the fly runs 4.8x slower than loading them, measured on the Mac, and the honest rate is unchanged on both vendors. Open: the same shortcut ratio on NVIDIA and on a discrete AMD card, and the time-memory trade-off between the two measured points. Inside the 5090's 96 MB cache the same program ran nearly six times faster, which is why the dataset starts at 2 GB and grows. On 4 October 2026 the live devnet crossed an hourly program change on all three vendors with no pause and no rejected block: a Mac at 26.7 million hashes a second, an RTX 5090 at 123 million and an integrated AMD chip at 2.7 million, every hash doing 128 distinct reads of the memory-hard dataset.</p></div>
