Thank you for your reply. I also think algorand is a very good blockchain, but I am asking a specific question and need to know the numbers if they are available.
According to the dashboard there are now 1423 (non-relay) nodes or participating in the consensus and in the last week 407 participated in the vote.
The number of relay nodes, which should not participate in the consensus, is 120 and are supported by the algorand foundation.
Practically all blockchains of a certain level, like algorand, have a section of their statistics where the distribution of the stake among validators is shown. Through it, the Nakamoto coefficient can be estimated.
@fabrice do you have any suggestions?
