March 12, 2024 replace: For the reason that preliminary publication of this put up, a number of shopper groups have made Dencun-compatible releases containing vital efficiency and stability enhancements. Whereas beforehand introduced variations are nonetheless thought of enough for the improve, a column has been added to the Shopper Releases tables highlighting the most recent beneficial variations for all shoppers.
- Mainnet blobs are coming .oO: Two years after its ETHDenver inception, dozens of testing calls and devnets later, protodanksharding is lastly going reside on mainnet!
- Dencun will activate on the Ethereum mainnet at epoch 269568, occurring on March 13, 2024 at 13:55 UTC. Node operators & stakers should improve their software program to releases listed on this announcement.

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, occurring on March 13, 2024 at 13:55 UTC.
The improve, which follows final 12 months’s Shapella improve, consists of a number of modifications, most notably the introduction of ephemeral information blobs with EIP-4844, also called “protodanksharding”, which is able to assist cut back L2 transaction charges.
If you would like to comply with the improve because it occurs, please be a part of the group livestream.
Improve Specification
The Dencun improve combines modifications to each Ethereum’s consensus and execution layers. The total checklist of protocol modifications will be present in EIP-7569. For reference, they’re:
Deneb
Full python specs for modifications affecting Ethereum’s consensus layer will be discovered within the deneb folder of the ethereum/consensus-specs repository.
Cancun
The EIPs linked above comprise the total specs for modifications affecting Ethereum’s execution layer.
Moreover, a python specification for these is being carried out within the ethereum/execution-specs repository.
Lastly, Deneb requires modifications 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 help Dencun on the Ethereum mainnet. The Minimal Model column signifies the bottom Dencun-compatible launch for a shopper whereas the Really helpful Model column highlights the most recent beneficial model for it. Really helpful Model releases usually comprise efficiency and stability enhancements. If upgrading from a Minimal to Really helpful model, be sure that to learn launch notes. Releases with vital breaking modifications haven’t been listed as Really helpful.
When selecting which shopper to run, validators ought to be particularly aware of the dangers of working 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
Notice: when working 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 is probably not appropriate for all manufacturing use instances. See the Reth README for extra context.
FAQ
As an Ethereum consumer or Ether holder, is there something I have to do?
In brief, no. You may be a part of us on the livestream to observe all of it occur reside!
When you use an alternate, digital pockets or {hardware} pockets you don’t want to do something except you might be knowledgeable to take extra steps by your alternate or pockets supplier.
When you run your individual Ethereum node, see the following query.
As a non-staking node operator, what do I have to 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 have to 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, in addition to any exterior dependencies, comparable to exterior block constructing software program.
Moreover, stakers who wish to run by means of the improve course of extra occasions 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 most recent model (listed above), your shopper will sync to the pre-fork blockchain as soon as the improve happens.
You can be caught on an incompatible chain following the outdated guidelines and will probably be unable to ship Ether or function on the post-Dencun Ethereum community.
As an utility or tooling developer, what ought to I do?
Overview the EIPs included in Dencun to find out if and the way they have an effect on your mission — there are numerous 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 comply with Devcon metropolis names. “Dencun” is the mix of Deneb, a first-magnitude star within the Cygnus constellation, and Cancun, the situation for Devcon 3.
Thanks to everybody who helped carry the blobs into existence, (practically) rid us of SELFDESTRUCT and usually ship yet another main overhaul to the Ethereum community .oO!
