Decentralization : NEO
Unfortunately it is not a switch you can flip. Political decentralization must be done slowly and carefully.
dBFT may be an efficient consensus approach, but it is very critical that the initial consensus nodes are not Byzantine (whether that be due to malicious entities or incompetent maintenance).
I expect we’ll see passable decentralization (community votes having an impact) sometime during 2019. Ideal decentralization will take longer, optimistically 2021 (and that’s assuming NF finds some creative ways to distribute tokens as they reach high value).
Keep in mind that there are approximately zero decentralized blockchains currently, including the heavy hitters. Some are closer to passable decentralization than others. Pure decentralization is still a pipe dream.
