Core developers of Ethereum (ETH) have postponed the activation of the Constantinople hard fork until late February. The upgrade is now set to be implemented at ETH block 7,280,000, as announced by a team lead at Ethereum, Peter Szilagyi, in a tweet Jan. 18.
In his announcement, Szilagyi explains that the activation will take place at block number 7,280.000, which is expected to be mined on Feb. 27, 2019. The upgrade will reportedly be implemented as “a single fork on mainnet and a post-Constantinople-fixup fork on the testnets to get them back in line feature wise with the main network.”
