March 12, 2024 replace: For the reason that preliminary publication of this submit, a number of shopper groups have made Dencun-compatible releases containing important efficiency and stability enhancements. Whereas beforehand introduced variations are nonetheless thought-about adequate for the improve, a column has been added to the Client Releases tables highlighting the newest really useful variations for all purchasers.
- 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 yr’s Shapella upgrade, consists of a number of modifications, most notably the introduction of ephemeral information blobs with EIP-4844, also called “protodanksharding”, which can assist cut back L2 transaction charges.
If you would like to observe the improve because it occurs, please be part of the community livestream.
Improve Specification
The Dencun improve combines modifications to each Ethereum’s consensus and execution layers. The complete checklist of protocol modifications could be present in EIP-7569. For reference, they’re:
Deneb
Full python specs for modifications affecting Ethereum’s consensus layer could 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 applied 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.
Consumer Releases
The next shopper releases assist Dencun on the Ethereum mainnet. The Minimal Model column signifies the bottom Dencun-compatible launch for a shopper whereas the Advisable Model column highlights the newest really useful model for it. Advisable Model releases usually comprise efficiency and stability enhancements. If upgrading from a Minimal to Advisable model, ensure that to learn launch notes. Releases with important breaking modifications haven’t been listed as Advisable.
When selecting which shopper to run, validators must be particularly conscious 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 could be discovered here. An estimate of present EL and CL shopper distribution and guides for switching from one shopper to a different could be discovered here.
Consensus Layer Mainnet Releases
Notice: when working a validator, each the Consensus Layer Beacon Node and Validator Consumer have to 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 circumstances. See the Reth README for extra context.
FAQ
As an Ethereum consumer or Ether holder, is there something I must do?
Briefly, no. You may be part of us on the livestream to observe all of it occur reside!
In the event you use an alternate, digital pockets or {hardware} pockets you do not want to do something except you’re knowledgeable to take further steps by your alternate or pockets supplier.
In the event you run your personal 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 purchasers 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 purchasers to the variations listed within the desk above. Be sure each your beacon node and validator shopper are up to date, in addition to any exterior dependencies, similar to exterior block constructing software program.
Moreover, stakers who need to run by 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 isn’t 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 can be caught on an incompatible chain following the outdated guidelines and might be unable to ship Ether or function on the post-Dencun Ethereum community.
As an utility or tooling developer, what ought to I do?
Evaluation the EIPs included in Dencun to find out if and the way they have an effect on your mission — there are lots 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 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 customarily ship yet another main overhaul to the Ethereum community .oO!
