dTAOscan: the Bittensor subnet explorer

dTAOscan is live. It does one job: make Bittensor's dTAO subnet economy legible. 129 subnets, live prices, emissions, and movement, on a page that loads fast and asks nothing from you.

It is the second instrument off the same bench as MorScan. Same philosophy: read the chain, show the numbers, let anyone check them.

Chain-exact, to the decimal

Prices are computed from chain state, not scraped from someone else's dashboard. We verified them against taostats to six decimal places; where a display disagrees, the chain wins. Netuid 0, the root network, is excluded from subnet accounting because it is not a dTAO subnet. Every subnet gets its own page with price history and the numbers that matter for staking decisions.

Your portfolio, no wallet connection

Paste any TAO address and dTAOscan shows the portfolio: which subnets, how much, what it is worth right now. There is no connect-wallet button anywhere on the site, by design. A lookup needs an address, which is public information; it does not need a signature, a session, or a popup asking for permissions it has no business asking for.

Every read is signed

API reads carry an Ed25519 provenance receipt, signed in the Worker at the moment the data is served. The signing key is published at dtaoscan.io/keys.json, so anyone can check that a response came from dTAOscan and arrived unaltered. A signature proves who served the numbers and that nobody changed them in flight; the chain itself remains the place to check what the numbers should be.

The MorScan seam

Under the hood it is a Cloudflare Worker in front of a D1 database, and it is built on the same open-core seam architecture as MorScan: a lean core composed with analytics and commerce plugs behind documented sockets. One pattern, two chains, and the next instrument off this bench gets it for free.

The weave

dTAOscan is an instrument, not an island. Its daily subnet readings flow into the DRM3 lakehouse as a signed daily stream, and the day's biggest subnet movers ride that stream into Truth Foundry's ticker and crypto desk. A price move on a Bittensor subnet becomes a fact row with a receipt, and then, when it is big enough, news.

Built light

The whole thing runs at the edge on infrastructure that costs effectively nothing to operate, which is why it is free and will stay free. No account, no key, no paywall on reading.
