Per the Ethereum developers call which took place today, it has been agreed that Constantinople will have to wait 6 more weeks.
According to Vitalik’s comments, the hard fork will come around block number 7.25 million to 7.3 million, which is estimated to be mined at some point on the last two weeks of February. Later statements by developer Péter Szilágyi narrow down the date even more, to block 7.28 million.
Update: we are targeting February 27, 2019, block number still to be figured out which is a bit more involved due to increasing block times (difficulty bomb).— Afri ⬙ Schoedon (@5chdn) January 18, 2019
On the call, several other relevant developers were present, such as Hudson Jameson, Afri Schoedon or Danny Ryan, among others.
The delay proposal comes after the safety firm ChainSecurtiy flagged earlier this week a critical vulnerability in Constantinople.
Twitter reactions to the news came mostly from TRON supporters hoping that their token would take the chance.
