Decentralization in the active set of validators is something very complicated to achieve and it happens in most PoS networks. It's disturbing to learn how decentralized Polkadot's active set is. We know that we have whale validators (which have multiple validator nodes) and exchanges. We don't have a lot of independent validators going into the active set. The TurboFlakes bot (https://github.com/turboflakes/one-t) provides an interesting fact that says that 182 validators from the active set have 100% commission. What I have been asking for a long time and would love to have in the ecosystem (both in Kusama and Polkadot) is a website/dashboard that shows the concentration of the stake.
For example:
Showing that Binance has X validator nodes and that it controls x% of the stake by attaching all the stake of its different nodes.
That shows all the people who have multiple validator nodes (how many they have and their representation in the total stake).
These are basic examples but you can add much more advanced information and important metrics.
I do not know if this already exists (tell me) but if not, I invite you to do so, it can be financed and/or maintained by the Treasury if the Council wishes. By having this type of data, we will achieve greater transparency and better education regarding the selection of validators.
I await your opinions.
