I think it will depend on the teams / companies launching the chains. We will potentially see a range of levels of decentralisation.

For example the NFL could launch a COSMOS chain with the 32 teams of the NFL each providing a node/validator. The chain could have NFL NFTs, team tokens, gambling dApps, sports prediction dApps, team related Defi, ticket dApps etc etc.

It's questionable if this would really be a "blockchain" in its fullest sense, and whether it would be simpler to just set up the same applications on a purely centralised basis. But as blockchain ideas gain traction, companies and organisations may step in with their half-way offerings.

You will then have fiat (guaranteed by the government), organisation tokens (with some level of guarantee from the issuing organisation) and decentralised, trustless coins.

Wider organisations (such as university groups) could look for a more decentralised approach with thousands of nodes across members in many countries and no overall control. It's arguable that this provides more decentralisation than an organically-grown L1 blockchain.

For many existing Pos or dPos L1 blockchains the level of decentralisation is unclear. Particularly since the ownership of tokens is anonymous.
