The call sign

$POP

Creator fees of $POP are forwarded by hand to the keeper wallet, and the keeper splits every arrival 80 to the probes, 15 to servers and storage, 5 to buying and burning $POP.

How it works

1. A task, every 30 seconds.

   The server names one public endpoint, a method and a random nonce. Your browser calls it and reports the time, the status, the size, and for an RPC the slot and the blockhash it got back.

2. The answer is checked.

   The slot and blockhash are compared with a reference node, so the call has to have happened just now. Your region comes from the connection and has to agree with your round trip to this server.

3. The neighbours decide.

   Measurements are grouped by target, map cell and country. Anything inside the group's normal spread is accepted. An outlier is rejected and told why, and a measurement with nobody to agree with yet counts at a quarter until it has neighbours.

4. The pool pays, rare places pay more.

   Every minute the probe pool is split by weight. A cell's weight is one over the square root of the probes in it this hour, so the hundredth measurement from Frankfurt is worth little and the first from Nairobi is worth a lot.

What the probes are watching

Every target is a public endpoint a browser is allowed to call. The list is built from what actually answers a browser: anything that refuses a cross origin call cannot be measured properly and is marked for what it is. Each target is kept under 120 calls a minute from the whole network, which is less than an ordinary site sends it; above that, probes are asked to sit a window out rather than the endpoint being hammered.

The table fills once probes in your region have reported.

Every target here, fastest first

The week not yet

Every closed hour is folded into a ring of 168, and the ranking is the median of those hourly medians, so one bad minute in one city cannot decide a week.

Target

Where probes are needed

The world is cut into cells of five degrees. A cell's weight is one over the square root of the probes that reported from it this hour, so the map fills itself: the emptier the cell, the more its next measurement is worth.

Keeper wallet

Every arrival on the keeper wallet is split 80 / 15 / 5 the moment it lands. The probe share is paid out over the following day, a minute at a time.

Hourly anchors

Once an hour the keeper writes the SHA-256 of that hour's measurement table into a memo on Solana, with the row count. The table cannot be rewritten afterwards without the hash changing.

The open API

The same data the map is drawn from, as JSON, with no key. Sixty requests a minute per address, and every answer carries the second it was computed.

Press try on the left and the real answer appears here.

The pool pays for measurements, not for holding: $POP is a memecoin, nothing here is financial advice, and the token can go to zero and take whatever you put into it with it.
