March 12, 2024 replace: Because the preliminary publication of this publish, a number of consumer groups have made Dencun-compatible releases containing important efficiency and stability enhancements. Whereas beforehand introduced variations are nonetheless thought of adequate for the improve, a column has been added to the Client Releases tables highlighting the newest 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 stay 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 upgrade, consists of a number of adjustments, most notably the introduction of ephemeral knowledge blobs with EIP-4844, often known as “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 community livestream.
Improve Specification
The Dencun improve combines adjustments to each Ethereum’s consensus and execution layers. The total listing of protocol adjustments could be present in EIP-7569. For reference, they’re:
Deneb
Full python specs for adjustments affecting Ethereum’s consensus layer could 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 carried out 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.
Consumer Releases
The next consumer releases help Dencun on the Ethereum mainnet. The Minimal Model column signifies the bottom Dencun-compatible launch for a consumer whereas the Beneficial Model column highlights the newest beneficial model for it. Beneficial Model releases sometimes include efficiency and stability enhancements. If upgrading from a Minimal to Beneficial model, ensure to learn launch notes. Releases with important breaking adjustments haven’t been listed as Beneficial.
When selecting which consumer to run, validators needs to be particularly conscious of the dangers of operating a majority consumer 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 consumer distribution and guides for switching from one consumer to a different could be discovered here.
Consensus Layer Mainnet Releases
Notice: when operating 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 consumer 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 person or Ether holder, is there something I must do?
In brief, no. You possibly can be a part of us on the livestream to look at all of it occur stay!
When you use an trade, digital pockets or {hardware} pockets you don’t want to do something except you’re knowledgeable to take further 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 suitable 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 suitable 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 consumer are up to date, in addition to any exterior dependencies, equivalent to exterior block constructing software program.
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?
In case you are utilizing an Ethereum consumer that’s not up to date to the newest model (listed above), your consumer will sync to the pre-fork blockchain as soon as the improve happens.
You’ll be caught on an incompatible chain following the previous guidelines and can be unable to ship Ether or function on the post-Dencun Ethereum community.
As an utility or tooling developer, what ought to I do?
Evaluate the EIPs included in Dencun to find out if and the way they have an effect on your undertaking — there are various 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 deliver the blobs into existence, (almost) rid us of SELFDESTRUCT and customarily ship yet another main overhaul to the Ethereum community .oO!
