The Ethereum community shall be present process a scheduled improve at block quantity 13,773,000, which is predicted to happen on Wednesday, December 8, 2021. The precise date is topic to alter as a consequence of variable block occasions and timezones. Please improve your node earlier than Sunday, December 5, 2021 to account for the variable block occasions.
What’s Arrow Glacier?
The Arrow Glacier community improve, equally to Muir Glacier, modifications the parameters of the Ice Age/Problem Bomb, pushing it again a number of months. This has additionally been finished within the Byzantium, Constantinople and London community upgrades. No different modifications are launched as a part of Arrow Glacier.
The issue bomb solely impacts Proof of Work networks, and therefore solely exists on the Ethereum mainnet and the Ropsten check community. With the recent progress in the direction of Ethereum’s transition to Proof of Stake, it was determined to solely delay the bomb on mainnet for now and to try to run the Proof of Stake transition on Ropsten earlier than the bomb goes off on that community.
To study extra about Arrow Glacier and the historical past of the issue bomb, see the Ethereum Cat Herders’ explainer blog post.
Shopper Variations
With a purpose to be appropriate with the Arrow Glacier improve, node operators might want to replace the shopper model that they run to one of many ones listed beneath:
Word: OpenEthereum, which was announced as deprecated earlier this year, has launched help for Arrow Glacier underneath model quantity 3.3.0-rc.14, which you’ll be able to obtain here.
For now, we nonetheless advocate following the prior deprecation warnings and deciding on another shopper software program. In case you select to make use of OE for the Arrow Glacir improve, please train warning and independently evaluation modifications to the codebase previous to working in manufacturing.
Improve Specification and EIPs
The complete specification for the improve could be discovered within the execution-specs repository here.
A single EIP is included within the improve: EIP-4345: Difficulty Bomb Delay to June 2022.
As an Ethereum person or ether holder is there something I must do?
In case you use an change, an internet pockets service, a cell pockets service, or a {hardware} pockets you do not want to do something except you might be knowledgeable to take further steps by your change or pockets service.
As a node operator or miner, what do I must do?
Obtain the most recent model of your Ethereum shopper, as listed within the desk above.
What occurs if I’m a miner or node operator and I don’t take part within the improve?
In case you are utilizing an Ethereum shopper that isn’t up to date to the most recent model (listed above), your shopper will sync to the pre-fork blockchain as soon as the improve happens. You may be caught on an incompatible chain following the previous guidelines and you can be unable to ship Ether or function on the post-upgrade Ethereum community.
What’s a community improve in Ethereum-land?
A community improve is a change to the underlying Ethereum protocol, creating new guidelines to enhance the system. The decentralized nature of blockchain techniques makes a community improve tougher. Community upgrades in a blockchain require cooperation and communication with the group, in addition to with the builders of the assorted Ethereum shoppers to ensure that the transition to go easily.
What occurs throughout a community improve?
After the group involves an settlement regarding which modifications ought to be included within the improve, modifications to the protocol are written into the assorted Ethereum shoppers, reminiscent of geth, Erigon, Besu and Nethermind. The protocol modifications are activated at a particular block quantity. Any nodes that haven’t been upgraded to the brand new ruleset shall be deserted on the previous chain the place the earlier guidelines live on.
Why “Arrow Glacier”?
Whereas we have just lately been utilizing Devcon names for community upgrades, after we beforehand had an improve that solely pushed again the bomb, we determined to change nomenclature. To focus on the character of the improve (pushing again the “Ice Age”), we went with a glacier identify, therefore Muir Glacier.
This improve follows an analogous sample. As a result of the transition to Proof of Stake is on the horizon, a retreating glacier was chosen, therefore Arrow Glacier 🏔!
Thank You!
An enormous because of the Ethereum group and to all Ethereum builders throughout all shoppers and platforms who come collectively to supply enter, ideas, and contributions. This is perhaps the final community improve on Ethereum earlier than the transition to Proof of Stake. Let’s go!
Additionally, many because of Harshil Gudka for the duvet picture.
That is an emergent and evolving extremely technical house. In case you select to implement the suggestions on this put up and proceed to take part, it is best to ensure you perceive the way it impacts you.

By selecting to implement these suggestions, you alone assume the dangers of the results. This put up and proposals should not a sale of any variety, and don’t create any warranties of any variety together with however not restricted to something associated to the Ethereum community, or the Ethereum shoppers referred to herein.
