How many people use Nuthatch

After your first nuthatch init, Nuthatch asks once whether it may count you. The default is no. These are the totals from everyone who said yes. Most people say no or are never asked, so every number here is a floor.

Reading the counter...

What is sent

With a yes, each init sends one object like this to https://count.nuthatch-indexer.com. It carries the version, the platform, a chain id from the built-in list (anything else is sent as 0) and which kind of init it was. There is no identifier and no address. nuthatch count payload prints yours.

init
{"v":1,"event":"init","version":"4.15.0","os":"linux","arch":"x86_64","chain":42161,"source":"addresses"}

What is kept

A tally per day for each of those values, and nothing else: no IP address, no header, no copy of the request. The receiver's source is short enough to check that in a few minutes. Anyone can send a ping, so the totals can only be read as floors.

Changing your mind

nuthatch count off stops it, and nuthatch count shows where things stand. Setting NUTHATCH_NO_COUNT or CI silences it on that machine.
