Interesting post and good to see you posting on Hive,

One of the biggest issues with the EOS mainnet was the rise of Exchange BPs - effectively a cartel - that calcified in the top 20-30 block producers. Developers and community leaders suffered as a result and often positive contributions to the ecosystem struggled to earn enough block rewards to support their development projects and many were forced to move to sister chains or abandon their projects.

Is it inevitable for all DPOS chains, as suggested by Brendan Blumer, that a control group effectively always appears (BTC mining pools, vote trading, etc)? And what are some ways to that DPOS chains can maintain a healthy balance in their ecosystem and negate the formation of control groups who are only interested in profitability and maintaining their position at the top of the food chain?

Cheers
