Goerli Dencun Announcement

  • The blobs are coming: Dencun will go stay on Goerli at 6:32 UTC on January 17, 2024.
  • Dencun might be Goerli’s final improve earlier than core groups cease supporting it. Extra on this in a earlier put up.
  • Assuming the Goerli improve goes properly, the Sepolia and Holesky testnets will activate Dencun over the following few weeks.
  • To obtain an e-mail alert for community improve bulletins, subscribe right here.

The Dencun community improve is scheduled to activate on the Goerli testnet at 6:32 UTC on January 17, 2024. The improve consists of a number of modifications, most notably the introduction of ephemeral knowledge blobs with EIP-4844, also referred to as “protodanksharding”, which is able to assist cut back L2 transaction charges.

Dencun follows final 12 months’s Shapella improve. It would first be deployed to the Goerli testnet. Then, if no main points are discovered, to Sepolia and Holesky. As soon as Dencun is working easily on all three testnets, mainnet activation might be scheduled.

Dencun might be Goerli’s final improve. After it has been activated on mainnet, consumer and EF testing groups will cease supporting the Goerli testnet. For extra particulars, see this earlier announcement.

Improve Specification

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


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


The EIPs linked above include the complete 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 file of the ethereum/execution-apis repository.

Consumer Releases

The next consumer releases assist Dencun on Goerli. Additional variations will activate assist on different testnets and mainnet. As soon as these are launched, one other announcement might be made right here.

When selecting which consumer to run, validators needs to be particularly conscious 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 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 Goerli Releases

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

Execution Layer Goerli Releases

Notice: whereas Reth helps Dencun, the consumer remains to be pending a full audit and is not beneficial for manufacturing use. See the Reth README for extra context.

Dencun Bug Bounty Bonus

All Dencun-related bug bounties for in-scope vulnerabilities will obtain a 2x multiplier between now and two weeks previous to when the mainnet improve is scheduled to happen. Important bugs at the moment are value as much as $500,000 USD! See the bug bounty program for extra particulars.


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

Briefly, no.

Should you use an change, digital pockets or {hardware} pockets you do not want to do something except you might be knowledgeable to take extra steps by your change or pockets supplier.

Should you run your individual Ethereum node, see the following query.

As a non-staking Goerli node operator, what do I have to do?

To be appropriate with the Goerli improve, replace your node to the model of your Ethereum consumer listed within the desk above.

As a Goerli staker, what do I have to do?

To be appropriate with the Goerli improve, replace your node to the model of your Ethereum consumer listed within the desk above. Ensure each your beacon node and validator consumer are up to date!

As a non-Goerli node operator or staker, what do I have to do?

Nothing for now. Additional bulletins might be made for Dencun’s activation on Sepolia, Holesky and mainnet. You possibly can signal as much as obtain an e-mail alert for them right here.

Stakers who need to run via the improve course of extra occasions earlier than mainnet are inspired to make use of, which is able to quickly assist Dencun.

What occurs if I’m a Goerli staker or node operator and I don’t take part within the improve?

If you’re 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 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?

Overview the EIPs included in Dencun to find out if and the way they have an effect on your undertaking — 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.

The place can I comply with the improve taking place?

The Goerli improve might be livestreamed here.

Why “Dencun”?

Upgrades to the consensus layer use star names, and people to the execution layer comply with Devcon metropolis names. “Dencun” is the mixture of Deneb, a first-magnitude star within the Cygnus constellation, and Cancun, the placement for Devcon 3.
