hits verified (blocks mined)
The verification work, explained
What every mined block actually is
Galaxy SIGNAL doesn't hash arbitrary numbers. Each block starts from a real radio-astronomy detection (a "hit") from Breakthrough Listen's public L-band survey, and the network's Proof-of-Useful-Verification (PoUV) is a real RFI-vs-candidate triage decision -- the same kind of decision the original survey's own pipeline had to make.
The network's work, so far
Every confirmed block is one hit that cleared the verification threshold. This updates live from the chain itself.

Out of ~28.86 million raw hits in the source dataset -- only those scoring above the verification threshold ever become a block. See the explorer for the full, browsable list, including sky position (RA/DEC) for each.
Where every mined hit actually falls, live
This chart is not a fixed example -- it's every block the network has ever mined, replotted from the live chain on every page load. It grows on its own as more blocks come in. The shaded bands mark frequency ranges known to be crowded with terrestrial transmitters (air-traffic radar, GPS) -- the same three bands the classifier itself checks.

– of mined blocks fall outside those crowded bands -- a live, growing signal that the network is spending its work on hits that look genuinely uncommon, not just re-finding known interference.
How a hit gets a score
A model trained on real labels -- not a hand-tuned heuristic. Labels come from cross-referencing "ON" (pointed at the star) against "OFF" (pointed away) observations of the same cadence: a signal that shows up in both is terrestrial interference (RFI), not a signal from the star.
Four features per hit -- frequency, drift rate, signal-to-noise ratio, and whether the frequency falls in a band known to be crowded with terrestrial transmitters (air-traffic radar, GPS) -- feed a Random Forest classifier. The output is a single number from 0 to 1: the model's confidence that a hit is NOT interference. A block can only be mined once that score clears a fixed, network-wide threshold.
This is deterministic: the same hit, scored by the same model, gives the same number on every node -- required for the network to independently re-check every block.
Which hit gets tried, and proving it's real
Scoring a hit only means something if nobody could see it coming and if it's actually a real detection. Two more checks, alongside the score, that every node re-verifies independently.
Unpredictable candidate window. Which hits are even eligible to try for the next block is derived from the previous block's own hash -- the window doesn't exist, even to the miner who ends up using it, until the block that seeds it does. A public dataset with a fixed reading order would otherwise let anyone pre-score candidates for several blocks ahead of time, off-network.
Hit authenticity. Every node holds its own local copy of the canonical dataset and looks up any hit a block claims by its exact position, requiring every field to match. A set of numbers engineered to clear the classifier but never actually observed by any telescope gets rejected here, not accepted as a genuine detection.
Every score the network has actually produced
No offline comparisons, no hand-picked examples -- these are the verification scores behind every block the network has mined, straight from the live chain, refreshed as the network mines more. Every block shown here already cleared the threshold; what varies is by how much, and whether its hit sits inside a frequency band already known to be crowded with terrestrial transmitters.

A permanent copy, for citing this outside the chain
Everything above is live, which is exactly the point -- but a live page changes under the same URL every time a block is mined, which makes it a poor thing to formally cite. This is what the deposit below is for.
Every 100 confirmed blocks, the network automatically publishes a snapshot to Zenodo -- a research-data archive run by CERN and OpenAIRE, the standard place independent and citizen-science work gets a permanent, citable DOI without needing a journal's gatekeeping first. Each snapshot contains the full hit data behind every block mined so far, the verification score, and the exact classifier model file that produced it -- so a third party can independently re-score any row and reproduce the number, without trusting this project's own servers.
Every snapshot is published as a new version of the same record, under one permanent DOI that always resolves to whichever is most recent -- while every earlier version stays exactly as published, forever. See /dataset for the current DOI, files, and download links, always pulled live from Zenodo's own record.
What this is not
Worth saying plainly, not burying in a footnote.
This system does not claim to have found a technosignature. The underlying data is public, and the original survey already concluded -- after a much more thorough, multi-signal analysis -- that none of these target stars host the kind of transmitter it searched for.
What's novel here isn't the astronomy -- it's the system: a way to turn continuous, incentivized, independently-auditable triage of real scientific data into the actual consensus work of a blockchain, instead of throwing away the electricity on arbitrary hashing.
