Ethereum Istanbul hard fork will be carried out twice, and 6 code changes have been confirmed

According to Coindesk's August 17 report, Ethereum's core developers finalized an upgrade list on Thursday, including six different code changes, and will be activated in the next system upgrade of Ethereum – Istanbul. And implement these code changes.

In the previous meetings, the developers of Ethereum had agreed that Istanbul would be implemented in two phases. The first phase will include all six codes or changes to the Ethereum Improvement Agreement (EIPs), which is initially expected to be implemented on the Ethereum mainline in October this year.

The second phase is planned to be implemented on the main site in the first quarter of next year, involving several Ethereum improvement agreements that require further testing and consideration by core developers, including a mining algorithm improvement known as "ProgPoW."

When it comes to the two-stage upgrade of Istanbul, Ethereum’s core developer Péter Szilágyi said on a conference call on Thursday:

We have completed Istanbul in two phases. The first phase will be implemented in a few weeks. The other stage includes two very significant Ethereum improvement agreements, so we may take longer to complete.

The first phase of the hard fork in Istanbul will be the eighth hard fork upgrade on Ethereum. It is expected to improve the interoperability of Ethereum and privacy currency Zcash, protect the network from replay attacks, and further improve the efficiency of the network.

Ethereum's main clients, such as Geth and Parity developers, will have a week to integrate the upgraded six Ethereum Improvements into their software and be ready to implement complete code on Ethereum's test network. .

The activation of the code on the test web is crucial

Although Istanbul’s initial appointment date for activation on Ethereum’s test network, Ropsten, was August 14th (Wednesday), Szilágyi stated in a conference call on Thursday that they needed to postpone the date for another two weeks in order to give developers more Time to determine which Ethereum improvements agreement to upgrade in the first phase of the Istanbul upgrade.

Since the core developers of Ethereum have just agreed to the Ethereum Improvement Agreement that needs to be upgraded, Szilagyi said that the hard fork activation time scheduled for the test network on the Spinsten on September 4 may be postponed again.

Szilágyi said on the phone:

In the previous hard fork, after the user upgraded the client, we will test it for a few months before launching the test network. Now, we have just listed the final Ethereum Improvement Agreement, and it is still a bit difficult for us to complete the activation of the test network within two weeks.

Other core developers agree with him and said that they will decide on the specific activation date of the test network at next week's meeting.

In the first phase of the upgrade in Istanbul, the activation of the test network will be the last level before the main network is activated. As with any previous hard fork upgrade, the miners of Ethereum must upgrade to the latest software at the same time, otherwise the network may split.

When it comes to the importance of the test version for hard fork upgrades, Hudson Jameson, community manager of the Ethereum Foundation, said:

When performing hard forks on the main network, the security and stability of the network is our main concern. Therefore, the release of the test network is an important step to ensure the smooth release of the main network.

Jameson later said that although the time to test the online line was delayed, all the core developers of Ethereum hope to successfully activate the first phase of the Istanbul upgrade on the test network.

Jameson said:

Ethereum's core developers are excited to be able to successfully activate hard forks on the test network of the Spinsten.
