I recently came across three separate platforms:
Qortal: https://qortal.org/
ZeroNet: https://zeronet.io/
and
Plebbit: https://plebbit.com/
That all claim to be completely decentralized.
There’s even talk about how Plebbit is more decentralized than the Fediverse, because the Fediverse is based off of instances.

And I was curious, would such a setup work better for the Fediverse, or is it basically just a huge scam/waste of time and money?


Blockchain is a bad choice for a social network, it’s expensive and all data is public. But since we’re talking about decentralization, let’s make a rough comparison.
Bitcoin: 24229 nodes (source: https://bitnodes.io/)
Fediverse: 30005 nodes (source: https://fedilist.com/)
Most of blockchain networks are much smaller than Bitcoin, so they don’t even come close to the Fediverse in terms of decentralization.
