I'd be curious what you mean by centrally coordinated and not PoS?
There are certain ways that Cardano is not yet fully decentralised to be sure but the network is operating as a proper decentralised PoS network.
The network has been transitioning from Federated nodes to Decentralised nodes (transferring by about 2% every 5 to 10 days) for the past few months. The d parameter (marking the transfer from 100% federated(1.0) to 100% decentralised(0.0)) ticked down to 0 at the end of last month and block production is fully decentralised.
Where it is still centralised:
- Peering between block producing nodes is currently manual however automatic peering will be enabled before the end of the quarter.
- Development is largely controlled by the Cardano Foundation, IOG, and EMURGO. This isn't unusual in the decentralised software space however the plan is to transition to handling development/feature contracts via on-chain voting and treasury disbursement (and this is already being trialled through Project Catalyst as a decentralised accelerator program) within a year or so. All feature integration and HFC event mechanics however are properly decentralised.
