The Ethereum Foundation has announced the next major network upgrade will take place on Jan. 1 2020.
A post published on Monday, the Ethereum Foundation has alerted developers and miners that the “Muir Glacier” upgrade is set to occur at 9.2 million blocks, which is currently on pace for New Year’s Day. The upgrade follows less than a month after Ethereum’s highly anticipated “Istanbul,” update, and marks a series of upgrades for the network as it transitions to Ethereum 2.0.
The official post states,
The Ethereum network will be undergoing a scheduled upgrade at block number 9,200,000, which is predicted to occur on Wednesday, January 1, 2020. The exact date is subject to change due to variable block times and timezones.
According to a previous post detailing the upgrade, Muir Glacier will serve to delay the planned increase in Ethereum’s mining difficulty by an estimated 611 days.
Ethereum Cat Herders provided an explanation for the delay,
Once the difficulty increase of the difficulty bomb is too great for the block time retargeting mechanism, it results in an increase in block times for the network. This results in a degradation in the usability of Ethereum due to waiting for confirmation for transactions and Dapps as everything takes longer throughout the network.
Node operators and miners will be required to download the updated client software in order to be in compliance with the network, which some users are bemoaning given the New Year’s Day holiday launch.
