The Ethereum community might be present process a scheduled improve at block quantity 13,773,000, which is predicted to happen on Wednesday, December 8, 2021. The actual date is topic to alter as a result of variable block occasions and timezones. Please improve your node earlier than Sunday, December 5, 2021 to account for the variable block occasions.
What is Arrow Glacier?
The Arrow Glacier community improve, equally to Muir Glacier, adjustments the parameters of the Ice Age/Difficulty Bomb, pushing it again a number of months. This has additionally been finished within the Byzantium, Constantinople and London community upgrades. No different adjustments 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 take a look at community. With the latest progress in direction of Ethereum’s transition to Proof of Stake, it was determined to solely delay the bomb on mainnet for now and to attempt 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 weblog submit.
Client Versions
In order to be appropriate with the Arrow Glacier improve, node operators might want to replace the consumer model that they run to one of many ones listed under:
Note: OpenEthereum, which was introduced as deprecated earlier this 12 months, has launched help for Arrow Glacier below model quantity 3.3.0-rc.14, which you’ll be able to obtain right here.
For now, we nonetheless suggest following the prior deprecation warnings and choosing an alternate consumer software program. If you select to make use of OE for the Arrow Glacir improve, please train warning and independently evaluate adjustments to the codebase previous to working in manufacturing.
Upgrade Specification and EIPs
The full specification for the improve will be discovered within the execution-specs repository right here.
A single EIP is included within the improve: EIP-4345: Difficulty Bomb Delay to June 2022.
As an Ethereum consumer or ether holder is there something I have to do?
If you utilize an change, an online pockets service, a cell pockets service, or a {hardware} pockets you don’t want to do something except you might be knowledgeable to take extra steps by your change or pockets service.
As a node operator or miner, what do I have to do?
Download the most recent model of your Ethereum consumer, 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?
If you might be utilizing an Ethereum consumer that’s not up to date to the most recent model (listed above), your consumer will sync to the pre-fork blockchain as soon as the improve happens. You might be caught on an incompatible chain following the previous guidelines and you may be unable to ship Ether or function on the post-upgrade Ethereum community.
What is 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 methods makes a community improve harder. Network upgrades in a blockchain require cooperation and communication with the group, in addition to with the builders of the varied Ethereum shoppers to ensure that the transition to go easily.
What occurs throughout a community improve?
After the group involves an settlement regarding which adjustments ought to be included within the improve, adjustments to the protocol are written into the varied Ethereum shoppers, corresponding to geth, Erigon, Besu and Nethermind. The protocol adjustments are activated at a particular block quantity. Any nodes that haven’t been upgraded to the brand new ruleset might be deserted on the previous chain the place the earlier guidelines live on.
Why “Arrow Glacier”?
While we have lately been utilizing Devcon names for community upgrades, once we beforehand had an improve that solely pushed again the bomb, we determined to modify nomenclature. To spotlight the character of the improve (pushing again the “Ice Age”), we went with a glacier identify, therefore Muir Glacier.
This improve follows the same sample. Because the transition to Proof of Stake is on the horizon, a retreating glacier was chosen, therefore Arrow Glacier đ!
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!
Also, many because of Harshil Gudka for the duvet picture.
