Ethereum developers have decided on an activation block number for the upcoming ETH Hardfork called “Constantinople”. As of today this is scheduled to go live on Feb. 27th, 2019 – The Hardfork has been set on block number 7,280,00.
Seems we’re going with block 7.28M for the #Ethereum Constantinople refork scheduled for the 27th of February! Will be 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.

The Ethereum Hardfork was delayed after a smart contract audit was conducted by the audit firm called ChainSecurity discovered a security flaw with the code. This hardfork will not include the Ethereum Improvment Proposals (EIPs), and the feature will be added into a future ETH Hardfork.
