⬆️ VNISH firmware for the Bitmain Antminer Z15 Pro begins where the model name stops Equihash is the algorithm. ZEC is the coin. XIL identifies the Xilinx control-board platform. NAND is the installation method. 1.3.7 is the Stable build The supported route is Z15 Pro / XIL / NAND, VNISH 1.3.7 Stable. BITMAIN rates the miner at 840 KSol/s with ±3% variation. The VNISH build exposes manual frequency and voltage contr…

Topic
Technology — a classification, not a measurement. An on-box language model (Qwen3.6-35B-A3B-FP8, prompt version 1) read this channel’s own recent posts on 11 September 2026 and assigned it the closest of 31 fixed categories, at 78% confidence. This is a model’s judgement about what the channel is likely to be about, not a fact this register measured the way a subscriber count or a view count is measured — it can be revised on a later pass, and it carries no weight anywhere else on this page. How this classification works, and the other topics.

ERR is average views per post over the last 30 days divided by subscribers, the definition TGStat uses, so this figure is comparable with the one you will see elsewhere. It falls structurally as a channel grows: a high ERR on a small channel and a low one on a large channel describe reach mathematics, not quality. We publish the figure and the sample it came from and pass no verdict on it.
ER is defined industry-wide as (forwards + reactions + comments) ÷ views — note the denominator is views, not subscribers. Telegram’s public web preview carries views and reactions but not forward or comment counts, so the reaction rate above is the reactions term only and is therefore a floor: the true ER for this channel is higher by an amount we have not measured and will not estimate.

Views are a single reading per post, taken at the time above. A post published in the last day or two is still accumulating views, which pulls the 30-day average down slightly. That is a property of the standard definition rather than a fault in it, so we keep the definition rather than “correcting” the number into something nobody can reproduce.
Precision. Telegram publishes view counts on its public widget in short form — 8.12K, 3.7M — so any reading at or above 1,000 reaches us rounded to three significant figures, and only counts below 1,000 are exact. Averages and rates derived from them are shown to the same precision rather than to the unit: a figure like 3,701,250 would assert digits nobody measured.
Reaction counts are published per emoji and rounded the same way, so a total below 1,000 is exact and a larger one is a sum that may carry a rounded component from each emoji above 1,000. Because it is a sum, it does not look rounded — read a large reaction total as three significant figures per contributing emoji rather than as the figure it prints.

Lifetime counters from Telegram’s own channel header, read 3 November 2026 — not the date at the top of this page, which is when the subscriber count was last read. Below Telegram’s rounding threshold, so these counts are exact.

Measured directly from 6 videos with a duration reading, out of the posts we hold for this channel — not this channel’s whole posting history, only the sample this register has actually read. An exact reading to the second, taken from the post itself rather than from Telegram’s own rounded chrome, so it carries no ≈ mark.

840 KSol/s looks huge until you ask what a solution is BITMAIN lists 840 KSol/s as the Z15 Pro's typical Equihash hashrate and states that actual hashrate can vary by ±3% That unit belongs to Equihash. SHA-256 miners use a different hashrate scale, so raw rates across these algorithms are not directly comparable. A hashrate figure by itself does not establish profitability either Read the algorithm and unit before…
512 DISTINCT INDICES / XOR TO ZERO Equihash is a proof-of-work puzzle, not a coin For Zcash mainnet, Equihash uses n=200 and k=9. A valid solution combines 512 distinct indices generated from the block header and nonce. Their derived values XOR to zero, and the solution must also satisfy Equihash binding rules That is the challenge behind ZEC proof-of-work on an Equihash miner such as the Antminer Z15 Pro VNISH l…
EQUIHASH / JOINS VNISH Z15 PRO / ZEC / 1.3.7 A new proof-of-work route changes the VNISH map For the first time in the current VNISH GLOBAL catalog, Equihash has a dedicated route: stable 1.3.7 for Antminer Z15 Pro, XIL board, NAND installation This is a model-specific build. The overall catalog default remains 1.3.6, while the Z15 Pro model default is 1.3.7 The listed coin is ZEC See the exact model route and i…
Not all of your miner’s hashing work is directed to your pool VNISH uses a development fee: a share of active hashrate goes to the developer’s pool while the firmware runs You can inspect that separation The interface shows statistics for your configured pools and a separate DevFee section with fee information and share statistics This changes what a useful firmware comparison should follow Look at the work accept…
Even an enormous mining operation cannot make an excessive Bitcoin block reward valid Bitcoin Core checks the blocks it receives One check compares the amount claimed in the coinbase transaction with the permitted subsidy plus transaction fees Claim more and the block fails, even if its proof of work meets the target Hashpower can influence which valid history accumulates the most work It cannot make a node follow…
The model name on an Antminer does not tell you everything the firmware needs to know The control board matters too For example, the S19j Pro The VNISH GLOBAL catalog lists separate builds for AML, BeagleBone, CV and Xilinx control boards Those files target different hardware Matching the name on the case is only the first part of matching firmware to the machine The installation route also depends on the combina…
Find a Bitcoin block and its reward is still not immediately spendable The first transaction, called the coinbase transaction, lets the miner claim the permitted block subsidy and transaction fees Its outputs have a special waiting period An output created at block height h can first be spent in block h + 100 Bitcoin Core enforces that age requirement A block containing an earlier spend fails validation The delay…
Your pool can accept thousands of mining results and still find no Bitcoin block Those results are shares They meet a target set by the pool, usually much easier than Bitcoin’s block target The ASIC is still hashing candidate block headers The easier threshold gives the pool more frequent evidence of the work you contribute Occasionally, a result also meets Bitcoin’s harder target If the complete block satisfies t…

A watt figure on a screen can come from two very different places With an APW12 power supply, VNISH calculates consumption for the selected preset from operating parameters That supply does not provide direct consumption telemetry, so actual draw can differ from the estimate A supported power supply with consumption telemetry gives the firmware a reading from the supply itself The interface can show watts in both …
Your miner has cooled down Why hasn’t it sped up? With automatic preset switching enabled, VNISH does more than watch the temperature In the currently documented logic, a preset decrease blocks a subsequent increase for 30 minutes That pause helps prevent frequent switching up and down around a threshold The pause ending is not an instruction to accelerate Temperature, available cooling and applicable power condit…
Showing the 12 most recent of 51 posts we hold for @roiasic_com. View and reaction counts are the latest single reading for each post, not a live figure, and a recent post is still accumulating both. A view count marked ≈ was rounded by Telegram before we ever saw it — t.me prints views in full below 1,000 and to three significant figures above, so ≈1,200,000 means somewhere between 1,150,000 and 1,249,999. Unmarked counts are exact. Text is reproduced from the public post preview and truncated for length.
Posts recorded as deleted after publishing
We recorded 1 post on @roiasic_com as deleted — posts this register held that were missing from the channel’s public page on two separate reads, taken from different network addresses at least an hour apart.
A deletion is not wrongdoing. This register can see that a post it held is no longer on the channel’s public page, and when — not why. Expired ad placements, reposts, rotating links and corrections all look the same. This is a count of recorded detections, not an exact total: it misses deletions we could not see, because only a post we held and later re-read inside the page can be seen to go, and it may include a small number of wrong records. How this is measured.
