Constantinople is the second part of the Ethereum updates in the fork of Metropolis. The first part included the Byzantine rigid fork which was implemented in October 2017.
Constantinople is an incompatible systemic update of the Ethereum network and is aimed at optimizing the network, reducing transaction fees and increased efficiency.  It is reported that the developers of Ethereum have already started to implement the code for the launch of updates.
According to an announcement made during a meeting for central developers, Constantinople will probably enter activation in the second week of October. It is scheduled to take place before the Devcon4 conference.
However, developers have not set the exact number of the block in which the hard fork will be activated.
Ethereum developers have spent the last few months looking for solutions to the scalability and efficiency issues that have plagued the Ethereum network.
An update like the one provided in Casper's implementation was considered as a possible step towards resolving part of this problem. Many developers believe that the activation of Constantinople is the key to finally bringing these solutions into use.
According to the announcement made last Friday, a temporary roadmap was developed. The roadmap proposes that the implementation of the code will continue until August 13th.
This phase will be followed by a test period that will last two months, including the release of a test network for the rigid fork.
Update of Ethereum Improvement
The hard fork will see the implementation of a series of updates that will greatly improve the Ethereum blockchain. The Ethereum improvement proposals (EIP) are oriented towards improving the structure and functionality of the network.
For example, developers have said that Constantinople will see four EIPs published. They will include,
"EIP 210, which reorganizes the way blocking hashes are stored in Ethereum and EIP 145, which increases the speed of arithmetic in the Ethereum virtual machine (EVM)."
The other two updates are EIP 1014 which will make it possible to add status channels to the Ethereum blockchain. There is also EIP 1052, which is a new operating code that compresses the way intelligent contracts interact.
These upgrades for improvement are the beginning of what will culminate in finding solutions to key challenges that have besieged the Ethereum Virtual Machine (EVM).  A successful implementation will likely see Ethereum retain its current dominance, even if it faces tough competition.
There have been numerous "Ethereum killer" platforms boasting better performances, such as EOS, Ziliqa, and Dfinity. Constantinople is very vital for Ethereum and the upcoming hard fork will help it keep up with a rapidly growing blockchain industry.
Ready for activation
According to Péter Szilágyi, a principal developer of Ethereum Geth, the developer team has already implemented most of the necessary changes. He also revealed that most EIPs are ready for activation.
Szilágyi told the meeting of developers and stakeholders that "IEPs are mostly concluded", promoting the belief that the hard fork will go ahead as planned.
The Constantinople hard fork is completing the second part in the Metropolis update. As we noted earlier, the first part constituted Byzantium, which was activated in October of last year
. The Byzantine update went live on Ethereum & # 39; s Block 4.370000. The hard fork introduced a total of nine EIPs.
At the heart of the first hard fork was the need to introduce changes that would improve the network by improving its security, privacy, and scalability protocols.
What remains is to ensure that the community embraces future changes and prevents any possibility of a result like the one that led to the creation of Ethereum Classic.
