Bitcoin is unique in that it presented the first viable decentralized solution to Sybil attacks (via proof-of-work).
To leverage that solution here, it would require that only people who successfully solve the proof-of-work puzzle are able to submit statements to the "decentralized lie detector", otherwise I could just spin up a billion VMs to spread the lies I wanted.
The only other solutions to this problem are centralized, a la government identification.
That said, the math is certainly cool; I just doubt it's very useful in a decentralized system.
