Hackers might be interested to know that there's an "open questions" section at the end of TFA. Some of it probably wants simulation, some wants theorems.

Camel-ai pubs/frameworks might be related and useful, for example: https://github.com/camel-ai/agent-trust

Several model checkers also have primitives for working with common-knowledge. TFA puts it like this:

> Learning a fact changes what you know. Seeing it displayed publicly — where everyone else can see it too — where you know others can also see it, changes what everyone knows, and subsequently how they act.

An important piece of technical vocabulary, it really seems we need this to talk about a lot of problems lately. Here is Terence Tao talking about some related math for disinformation and politics ( https://mathstodon.xyz/@tao/114866548969775485 ) and summing it up this way:

> we barely even have the vocabulary to discuss, let alone analyze, games in which control of information is a major battleground.

He kinda means in general though I think.. probably we can find heuristics and crunch a case or two
