The final week before the launch of a crypto's hard fork is always full of excitement. The same can be said with the upcoming Istanbul Hard Fork. The Ethereum Foundation has released the official hard fork announcement, detailing instructions for all interested parties.

Starter Pack for Hard Fork Participants

Hudson Jameson, Community Leader of the Ethereum Foundation, has officially confirmed that the Istanbul Hard Fork will be released on Saturday, December 7th, 2019. The exact time frames are subject to change due to variable block times.

The Ethereum node operators should upgrade their nodes before Sunday, December 1st, 2019 to account for the variable block times. With anticipation around the corner, users can trace the upgrade's progress online via Ethernodes tools, giving real-time status of preparations made by the developers, exchanges, miners, and nodes.

Furthermore, the official announcement offers a list of final releases that are compatible with the Istanbul upgrade. Apart from the most common Geth and Parity clients, there are some exotic implementations like Aleth, Besu, and Nethermind.

Rules to be Changed Forever

There is a warning in the official announcement. Once the upgrade occurs, if an individual uses an Ethereum client that is not up to date, then the node client will sync back to the pre-fork blockchain. This blockchain will be incompatible with the new Ethereum, and will be unable to send ether or operate on the post-upgraded Ethereum network.

Finally, the Ethereum Foundation states that if individuals are holding Ethereum (ETH) and/or utilize web wallets, mobile apps, exchanges, and hardware wallets, then they should not upgrade their tools unless asked by administrators of respective services.

Ethereum's Upcoming Istanbul Hard Fork Details Shared By Team Lead

The Istanbul Hard Fork is the last of Ethereum 1.0, as this will open a direct road to Serenity, the next status of settlement in the Ethereum network. Istanbul upgrade was postponed at least three times due to the delays with implementations.

What do you think? How will this upgrade affect the price of Ethereum? Will switching to the new rules be smooth? Write your predictions on our Twitter!
