And furthermore, a function of the observer. Schrodinger would be proud.

Feels like a lifetime ago ...

@naddr1qvzq...

Could be outbox model? I started looking into this, but didn't come to any conclusions.

Yeah, entities can make the same broad Assertion - the sky is blue.

I guess we could look at the hash of a subset of tags of a well-specified Assertion event to determine if it was the same?

Attestations basically amplify/dampen the views of a given entity as there is no base 'truth' - that is emergent and subjective.

The place example is a special case in that it is the *combination* of Place event content *and* npub we are interested in as we are seeking to link cyberspace ownership (nsec/npub) with meatspace ownership (physical address).

You should join the #wotathon calls by @nprofile1q...!

The spec is agnostic on the Assertion Event - it can literally be any other event of any kind. It's covered on the nostrhub link above.

The Assertion Event, to be useful, should be domain specific and as detailed as necessary such that a valid/invalid assesment can be made via an Attestation.

In your case directly above, you're not signing the assertion - that is the place event itself published by the merchant.

You would either be attesting to it directly, or attesting to the other attestations as you trust them implicitly. Both are fine.

Assertions can't be identical unless they are from the same key.

Attestations can also be attested to. 🙃

That's for clients to interpret with WoT.

The user doesn't sign anything.

In Proof of Place:

- The owner Asserts a Place
- Other entities then Attest to that being valid/invalid
- Users weigh those attestations how they like.

If I don't trust the government then I'll not weight their attestations on given kind types.

More directly in a swer to your question, the Attestations are linked by the Assertion Event (in this case a Place event).

Every signature is a waveform, collapse it responsibly!

If only there were an Attestation NIP 😉

Yeah, we could. We actually started there but concluded we needed something less open to interpretation, particularly as reactions are used for all sorts.

An Attestation should carry much more weight - like a notorisation.



Users and clients would need to weigh Attestations in accordance to their social graph and preferences using WoT. e.g. people may highly weight Proof of Place Attestations from BTC Map, but not music recommendations.
