'Ethereum Constantinople thread': Is that serious? Someone just created a thread for this! Is it official or did someone independently create this? ETH already be called PoS?
Ooopsss, sorry double post. Will just delete.
Nope, PoS related upgrade will be Serenity as far as I remember, anyone feel free to prove me wrong if I don't recall correctly

. Constatinople was for less blocks' reward and more smart contracts' security
Constantinople is a part of a serenity upgrade in the future, it has started by decreasing the block reward of ethereum and that last decrase will give miners 0.5 eth for each block reward. This system will become hybrid system
