The chip claim, public text (7 October 2026, 14:3x UK, on the project lead's "this needs updating with all of our updates"; served since 11:03 UK on master 9162c847 with main's two cuts: no mention of the disclosure prize until the publish word, and row 17 in evidence.md's eight-column shape)

Three texts and one ledger row, written by the Counter ASIC lane, which owns the chip model. Every number carries its label: measured (a card or a chain we ran, with the date), modelled (arithmetic on cited parts), claimed (a vendor's figure, never measured by us), designed (a rule in a class, not yet measured). Sources: docs/analysis/chip-model-v3.md sections 5 and 6, docs/analysis/latency-shadow-2026-10-06.md, docs/plans/counter-asic-3-status.md, docs/analysis/attack-pass/f8-uniform.md and f4-weakday.md (branch attack-pass), docs/design/class-v5-stored-state.md, the datacentre and market-cap rows of 7 October (lanes 3 and the fleet), the cryptanalysis plan in docs/plans/funding.md.

1. The home page's chip line (replaces the hero sentence served since 6 October 16:21Z)

Built for graphics cards. In our public model the strongest chip reaches 5x to 9x per joule against an RTX 5090 today; class v4, now on the vote, brings that to 2.1x to 3.9x, and class v5 makes the dataset the chain's own state, so a chip that stores it or recomputes it is wrong on every item. The model and every measurement are public.

2. The litepaper's chip section (replaces the paragraph that begins "The chip model: 5x to 9x per joule")

The chip model. We price the strongest chip we can design against an RTX 5090 and publish the arithmetic. The honest card: an RTX 5090 mines class v3 at 136 MH/s on 350 W in the bench and 290 W in the app (measured, 6 October 2026); an Apple M5 Max at 27 MH/s on 21 W (measured, 6 October 2026); an H100 SXM at 249 MH/s, 98 percent of its random-read ceiling like the 5090, 1.78x the 5090's hash at 1.15x the tuned 5090's hash per watt and a third of the hash per rented dollar (measured, 7 October 2026), so datacentre silicon does not change the chip question. The CPU verifier takes 2.33 ms per warp of 32 hashes on one M5 Max core under class v4 (measured, 6 October 2026), against a gate of 10 ms.

The chip and the class	Edge over an RTX 5090 per joule	Label and date
A memory-controller chip that stores the whole dataset (the Ethash class), class v3	5x to 9x (5.1x on GDDR7, 9.2x on eight HBM3 stacks; the Ethash chips of this class reached 2.1x to 4.8x)	modelled, 6 October 2026; the precedent measured by others, 2020 to 2022
The same chip under class v4 (about 100,000 integer ops per hash in the latency shadow, so the chip carries a GPU-class datapath beside its memory)	2.1x with a core as costly per op as the GPU's (k = 1); 3.9x with the core Bitmain claimed for its Antminer X9 (k about 0.33), a product withdrawn before any unit shipped	modelled on measured card watts, 6 October 2026; the X9 figure claimed, never measured
The same chip at the ladder's second rung (about 200,000 ops per hash)	about 2.8x	modelled, 7 October 2026
Any chip under class v5, where the dataset is the chain's own state	a stateless or stale chip is wrong on every item, so the stored-dataset chip and the recompute chip are removed as categories; the verifier pays 0.2 ms more per warp	designed, 7 October 2026
A chip caching the hottest 0.1 percent of items (about 1 MB of SRAM)	bounded at 1.067x at the ceiling, 1.005x on about half the hours and 1.048x on 5 percent	measured census of 1,024 programs, 7 October 2026; the source rule in the next class
A per-day FPGA that recomputes the dataset with cheap multipliers on a weak day	at most 12 percent more hash rate on 12 days a century, nothing on the other days and nothing for any chip	measured census of 2^24 days, 7 October 2026; the rule in the next class
When a stored-dataset chip pays for itself	at about USD 100 M of market cap in the first two years, not before	modelled, 7 October 2026

What a miner sees from this. Class v4 costs a 5090 about 80 W more for 0.2 percent of rate, an M5 Max 16 W more for 1.5 percent, an RX 9070 XT and an RTX 4070 nothing (all measured, 6 October 2026). The ladder that sets how much work rides in the shadow starts at rung 0 at the testnet genesis and climbs by miner signal; its third rung is inadmissible today because a server core verifies it in 10.85 ms, over the gate (measured, 7 October 2026). The next test of the model is not ours: the cryptanalysis plan buys three external lots against the mixer, the chained cache and the acceptance rule.

3. The miner page's line

Your card against the strongest chip we can price: an RTX 5090 at 136 MH/s on 350 W (measured 6 October 2026), the chip 5x to 9x per joule in the public model today, 2.1x to 3.9x under class v4 (modelled on measured watts), and under class v5 wrong on every item because the dataset is the chain's own state (designed); the model and the measurements are public.
