It has been postponed now it is planned for next month. This is upgrade for ETH protocol it will make switch to POS on this network. Read above comments which related to this issue.
wait, constantinople is not about switch to pos, correct? did i misunderstand your words?
maybe you mean that constantinople is a step before the next hard fork that will switch to POS/POW eth network?
Thank you for your clarification!
i request everyone to use the word upgrade instead of hard fork
