HomeEtherumAnnouncement: Upcoming Ethereum Muir Glacier Upgrade

Announcement: Upcoming Ethereum Muir Glacier Upgrade

Published on

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.

Please upgrade your node before Wednesday, December 30, 2019 to account for the variable block times

Ethernodes.org has kindly provided Istanbul node statistics and a countdown timer located at https://ethernodes.org/muir_glacier. etherscan.io has provided a countdown timer located at https://etherscan.io/block/countdown/9200000. You can monitor the network upgrade in real time at http://forkmon.ethdevops.io/ (it will be updated shortly before the fork).

What is Muir Glacier?

Muir Glacier is the name given to this network upgrade. Previous network upgrades have been given other names such as Istanbul, Costantinople, and Spurious Dragon.

As an Ethereum user or ether holder is there anything I need to do?

If you use an exchange (such as Coinbase, Kraken, or Binance), a web wallet service (such as Metamask, MyCrypto, or MyEtherWallet), a mobile wallet service (such as Coinbase Wallet, Status.im, or Trust Wallet), or a hardware wallet (such as Ledger, Trezor, or KeepKey) you do not need to do anything unless you are informed to take additional steps by your exchange or wallet service.

As a node operator or miner, what do I need to do?

Download the latest version of your Ethereum client:

NOTE: Harmony (ethereumJ) is now a deprecated client and will not be supporting Istanbul. Besu is a mainnet compatible Ethereum client written in Java.

Where can I learn more about this upgrade?

The Ethereum Cat Herders have put together a blog post which outlines why we are upgrading the network and what changes are going into the upgrade. You can find that blog post here.

Thank You!

A big thanks to the Ethereum community and to all Ethereum developers across all clients and platforms who came together to provide input, thoughts, and contribution.
