What Taosis can and cannot know
The one page to read first: why a blank is never a zero, and why some questions are refused outright.
Published 2026-09-01 · updated 2026-10-12
A blank is not a zero
Everywhere on this site, a value Taosis cannot verify shows as a dash. It never shows 0 in its place.
This matters more than it sounds. A fake zero is indistinguishable from a real measurement, and it reads as information when it is the absence of information.
History cannot be invented
The public lite node prunes old state within minutes. An archive node keeps every block, and Taosis reads one where a single past block answers the question: block pages, a wallet's value history, and each wallet's and holder's balances on 1 Sep 2026. Prices are the one series it has back-filled from it: every subnet's pool price read at past blocks, so the price charts go back to dTAO's launch on 13 Feb 2025. The other series Taosis builds itself — the index of fills behind volume and cost basis, its flow samples, epoch yields, validator reliability — begin when it began recording, and it has not back-filled them. Every figure that depends on one names its start date.
A series that started last week is one week long, and Taosis does not pad it with guesses.
Some questions get refused
A deregistration probability with no observed registrations returns nothing rather than 0%. A reliability verdict under twelve observations returns "insufficient". A holder concentration that does not reconcile against the chain is marked unverified. A price attribution that explains under 90% of a move is flagged partial.
Each of those could have been a confident-looking number. Each would have been wrong.
Where the numbers come from
Everything on the market side is read from the chain — subnet prices, reserves, emission, validator dividends, locks, hyperparameters. There is no third-party market data API in the product.
Two inputs do not come from the chain: the TAO/USD rate (CoinGecko), used only to convert τ figures to USD, and news content — the RSS and Atom feeds of subnet teams and of ecosystem outlets (blogs, newsletters, the press, Medium, Reddit, YouTube), Google News, the official X API, and GitHub release and commit feeds, which also give the development counts. Neither enters any τ price, pool, stake, emission or yield figure. Subnet logos are images Taosis's server downloads from the address in each subnet's on-chain identity. The rate and the news are labelled where they appear.

Reading price attribution
Trading versus emission, decomposed exactly rather than fitted — with the leftover always published.
Validator reliability
Taosis's record of each validator starts when it began sampling, so the verdict says "insufficient" until it has genuinely watched long enough. It is served by the public API.
Cost basis and P&L
WAC or FIFO, replayed over indexed fills — with coverage stated, because a partial history makes a fake profit.
