So, I didn't know that there is such thing as TRON 4.0. Yes, I'm excited with ETH 2.0 but I still have to study the TRON 4.0. Do you guys have some resources for this? But I guess I have to find it out myself.

The only problem I have with TRON is it is DPOS, so it is not really that Decentralized. DPOS consensus mechanism is like a cartel. Only a few holding a most of the coins.
