Ethereum (ETH) Constantinople Hard Fork Postponed to Late February

A recently detected security flaw has stood in the way of the ETH network upgrade’s timely launch.

The highly-anticipated Ethereum (ETH) Constantinople hard fork was delayed once again due to a security issue. The network upgrade is now set to roll out at ETH block 7,280,000, which is expected to be mined on February 27.

The decision was taken at a core developers meeting on Friday and announced by team lead Peter Szilagyi via Twitter:

“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 ETH Constantinople hard fork was originally planned for late 2018 and was then postponed to January 16. This latest change of schedule comes in the wake of a recently detected error in the protocol’s code, which could allow malicious attackers to steal ETH from smart contracts. The vulnerability has been discovered by smart contract audit firm ChainSecurity.

The Constantinople features five Ethereum Improvement Proposals (EIPs). The upgrades are designed to soften the transition from proof-of-work (PoW) to the more energy efficient proof-of-stake (PoS) consensus algorithm. As explained by Szilagyi, the EIP that contained the security flaw will be removed from the February hard fork and incorporated at a later time after more thorough testing can be done.

If successfully deployed, the ETH upgrade is expected to optimize the network, preventing any backward compatibility, which will make nodes update synchronically with the rest of the system or operate as an independent blockchain entity. Thus, providing a significant boost for both the Ethereum network and token.

In recent weeks, ETH Constantinople has received support from several major cryptocurrency exchanges, including Binance, OKEx and Huobi. Indian platform Koinex and Singapore-based Bitbox have also signaled their readiness to support the hard fork and all the upgrades.
