- The blobs are coming: Dencun will go dwell 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 previous post.
- Assuming the Goerli improve goes properly, the Sepolia and Holesky testnets will activate Dencun over the following few weeks.

The Dencun community improve is scheduled to activate on the Goerli testnet at 6:32 UTC on January 17, 2024. The improve contains a number of adjustments, most notably the introduction of ephemeral knowledge blobs with EIP-4844, often known as “protodanksharding”, which can assist cut back L2 transaction charges.
Dencun follows final 12 months’s Shapella upgrade. It is going to 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 previous announcement.
Improve Specification
The Dencun improve combines adjustments to each Ethereum’s consensus and execution layers. The complete checklist of protocol adjustments will be present in EIP-7569. For reference, they’re:
Deneb
Full python specs for adjustments affecting Ethereum’s consensus layer will be discovered within the deneb folder of the ethereum/consensus-specs repository.
Cancun
The EIPs linked above include the complete 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.
Shopper Releases
The next consumer releases help Dencun on Goerli. Additional variations will activate help 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 ought 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 will be discovered here. An estimate of present EL and CL consumer distribution and guides for switching from one consumer to a different will be discovered here.
Consensus Layer Goerli Releases
Be aware: when working a validator, each the Consensus Layer Beacon Node and Validator Shopper should be up to date.
Execution Layer Goerli Releases
Be aware: whereas Reth helps Dencun, the consumer remains to be pending a full audit and is not advisable 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 are actually price as much as $500,000 USD! See the bug bounty program for extra particulars.
FAQ
As an Ethereum consumer or Ether holder, is there something I must do?
Briefly, no.
When you use an change, digital pockets or {hardware} pockets you do not want to do something until you’re knowledgeable to take further steps by your change or pockets supplier.
When you run your personal Ethereum node, see the following query.
As a non-staking Goerli node operator, what do I must do?
To be suitable 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 must do?
To be suitable with the Goerli improve, replace your node to the model of your Ethereum consumer listed within the desk above. Make certain each your beacon node and validator consumer are up to date!
As a non-Goerli node operator or staker, what do I must do?
Nothing for now. Additional bulletins might be made for Dencun’s activation on Sepolia, Holesky and mainnet. You’ll be able to signal as much as obtain an e mail alert for them here.
Stakers who wish to run by way of the improve course of extra occasions earlier than mainnet are inspired to make use of ephemery.dev, which can quickly help 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 may be caught on an incompatible chain following the previous 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 venture — 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 observe 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 observe Devcon metropolis names. “Dencun” is the mixture of Deneb, a first-magnitude star within the Cygnus constellation, and Cancun, the situation for Devcon 3.
