Dencun Mainnet Announcement | Ethereum Basis Weblog

• 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, occuring 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, occuring on March 13, 2024 at 13:55 UTC.

The improve, which follows final yr’s Shapella improve, consists of a number of modifications, most notably the introduction of ephemeral information blobs with EIP-4844, often known as “protodanksharding”, which is able to assist scale back L2 transaction charges.

If you would like to observe the improve because it occurs, please be a part of the neighborhood livestream.

Improve Specification

The Dencun improve combines modifications to each Ethereum’s consensus and execution layers. The total listing of protocol modifications might be present in EIP-7569. For reference, they’re:

Deneb

Full python specs for modifications affecting Ethereum’s consensus layer might be discovered within the deneb folder of the ethereum/consensus-specs repository.

Cancun

The EIPs linked above include 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 consumer releases assist Dencun on the Ethereum mainnet.

When selecting which consumer to run, validators needs to be particularly aware of the dangers of working a majority consumer on both the execution layer (EL) or consensus layer (CL). An explainer of those dangers and their penalties might be discovered right here. An estimate of present EL and CL consumer distribution and guides for switching from one consumer to a different might be discovered right here.

Consensus Layer Mainnet Releases

Be aware: when working a validator, each the Consensus Layer Beacon Node and Validator Consumer should be up to date.

Execution Layer Mainnet Releases

Notes:

• Whereas Reth helps Dencun, the consumer is present process a full audit and is not but beneficial for manufacturing use. See the Reth README for extra context.
• Whereas Geth v1.13.13 totally helps Dencun, v1.13.14 comprises efficiency enhancements to the transaction pool’s dealing with of blob transactions and is thus beneficial.

FAQ

As an Ethereum person or Ether holder, is there something I have to do?

Briefly, no. You possibly can be a part of us on the livestream to look at 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 extra steps by your alternate or pockets supplier.

In the event you run your individual Ethereum node, see the subsequent 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. Be certain each your beacon node and validator consumer are up to date.

Moreover, stakers who wish to run by means 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 consumer that isn’t 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 may be caught on an incompatible chain following the outdated guidelines and can 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 mix of Deneb, a first-magnitude star within the Cygnus constellation, and Cancun, the placement for Devcon 3.

Thanks to everybody who helped deliver the blobs into existence, (almost) rid us of SELFDESTRUCT and customarily ship yet one more main overhaul to the Ethereum community .oO!
