Underlay – The world’s distributed knowledge graph

The github links are broken on that page. Also, why isn't there a "What we do" or similar section. I know of several people who are trying to build a knowledge graph, and each of them has a different definition.

> Assertions may be added to the Underlay by anyone; those who add an assertion are noted as part of its provenance.

What to do about spam?

It seems likely that Underlay repos will soon learn to allow-list assertions from trusted sources like Wikipedia and block-list those from random users, at least when querying and attempting to draw useful conclusions from the data.

At that point, does all of the distributed p2p stuff really add much values?

(This is not meant as a criticism, maybe it's addressed somehow, I'm curious)
