The Dencun community improve has efficiently activated on all testnets. It’s now set for deployment on the Ethereum mainnet and can activate on the community at epoch 269568, occuring on March 13, 2024 at 13:55 UTC.
The improve, which follows final 12 months’s Shapella improve, consists of a number of adjustments, most notably the introduction of ephemeral information blobs with EIP-4844, also called “protodanksharding”, which can assist scale back L2 transaction charges.
If you would like to observe the improve because it occurs, please be a part of the group livestream.
Improve Specification
The Dencun improve combines adjustments to each Ethereum’s consensus and execution layers. The total listing of protocol adjustments will be present in EIP-7569. For reference, they’re:
Deneb
Full python specs for adjustments affecting Ethereum’s consensus layer will be discovered within the deneb folder of the ethereum/consensus-specs repository.
Cancun
The EIPs linked above include the total specs for adjustments affecting Ethereum’s execution layer.
Moreover, a python specification for these is being applied within the ethereum/execution-specs repository.
Lastly, Deneb requires adjustments to the Engine API, used for communication between the consensus and execution layer nodes. These are specified within the cancun.md file of the ethereum/execution-apis repository.
Shopper Releases
The next shopper releases assist Dencun on the Ethereum mainnet.
When selecting which shopper to run, validators must be particularly conscious of the dangers of operating a majority shopper on both the execution layer (EL) or consensus layer (CL). An explainer of those dangers and their penalties will be discovered right here. An estimate of present EL and CL shopper distribution and guides for switching from one shopper to a different will be discovered right here.
Consensus Layer Mainnet Releases
Be aware: when operating a validator, each the Consensus Layer Beacon Node and Validator Shopper should be up to date.
Execution Layer Mainnet Releases
Notes:
Whereas Reth helps Dencun, the shopper is present process a full audit and isn’t but really helpful for manufacturing use. See the Reth README for extra context.Whereas Geth v1.13.13 totally helps Dencun, v1.13.14 incorporates efficiency enhancements to the transaction pool’s dealing with of blob transactions and is thus really helpful.
FAQ
As an Ethereum consumer or Ether holder, is there something I must do?
Briefly, no. You possibly can be a part of us on the livestream to look at all of it occur dwell!
When you use an trade, digital pockets or {hardware} pockets you do not want to do something until you might be knowledgeable to take extra steps by your trade or pockets supplier.
When you run your individual Ethereum node, see the following query.
As a non-staking node operator, what do I must do?
To be appropriate with the mainnet Dencun improve, replace your node’s execution and consensus layer shoppers to the variations listed within the desk above.
As a staker, what do I must do?
To be appropriate with the mainnet Dencun improve, replace your node’s execution and consensus layer shoppers to the variations listed within the desk above. Ensure that each your beacon node and validator shopper are up to date.
Moreover, stakers who wish to run by way of the improve course of extra instances earlier than mainnet are inspired to make use of ephemery.dev, which now helps Dencun.
What occurs if I’m a staker or node operator and I don’t take part within the improve?
If you’re utilizing an Ethereum shopper that’s not up to date to the newest 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 shall be unable to ship Ether or function on the post-Dencun Ethereum community.
As an software or tooling developer, what ought to I do?
Assessment the EIPs included in Dencun to find out if and the way they have an effect on your undertaking — there are a lot of new thrilling options being launched throughout each the execution and consensus layers! The one EIPs with backwards compatibility implications are EIP-6780, EIP-7044 and EIP-7514.
Why “Dencun”?
Upgrades to the consensus layer use star names, and people to the execution layer observe Devcon metropolis names. “Dencun” is the mixture of Deneb, a first-magnitude star within the Cygnus constellation, and Cancun, the placement for Devcon 3.
Thanks to everybody who helped carry the blobs into existence, (almost) rid us of SELFDESTRUCT and usually ship yet another main overhaul to the Ethereum community .oO!
