Why doesnt Dark Forest use XXXX chain?
The best way to explain what differentiates blockchains is the "blockchain trilemma" Blockchains need to be "Decentralized, Scalable, and Secure" (where cheap is part of scalable). It's impossible to have 100% of each of these, so each blockchain moves the dials around and sacrifices a little of one for the other. The developers are certainly aware of the blockchain ecosystem and are always trying to plan for the future. However the fact is switching chains costs developer time, which takes away from features and bug fixing. Only time will tell who survives and where Dark Forest will end up.
