This seems to be a new kind of social network, that combines mastodon (very obvious if you look at the UI), blockchain and artificial intelligence to give an assessment if a posts content is trustworthy.
I went to their website, but couldn’t find if they are part of the fediverse (ActivityPub) or not.
To me it seems kinda silly and not like a real improvement over standard mastodon. I do like that they tried to tackle the problems of modern social media, like fake news etc.
Also the mixture of the mastodon icons with the “I trust this” and “I don’t trust this” icons is so horrible, they don’t fit together at all.
2/10, I’ll stay with mastodon.
Blcokchain is useful, if you need an independent trust anchor. In most cases, it is absolutely useless, but here it might finally be a real usecase for blockchain, besides crypto currency scam.
