- 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 submit.
- 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 consists of a number of adjustments, most notably the introduction of ephemeral knowledge blobs with EIP-4844, often known as "protodanksharding", which is able to assist scale back L2 transaction charges.
Dencun follows final 12 months’s Shapella improve. It should 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 adjustments to each Ethereum’s consensus and execution layers. The total checklist of protocol adjustments may be present in EIP-7569. For reference, they’re:
Deneb
Full python specs for adjustments affecting Ethereum’s consensus layer may 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 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 must 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 may be discovered right here. An estimate of present EL and CL consumer distribution and guides for switching from one consumer to a different may be discovered right here.
Consensus Layer Goerli Releases
Word: when working a validator, each the Consensus Layer Beacon Node and Validator Consumer have to be up to date.
Execution Layer Goerli Releases
Word: 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. Vital bugs are actually value 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 have to do?
Briefly, no.
In the event you use an trade, digital pockets or {hardware} pockets you do not want to do something until you might be knowledgeable to take further steps by your trade or pockets supplier.
In the event 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 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 have to do?
To be suitable with the Goerli improve, replace your node to the model of your Ethereum consumer listed within the desk above. Be sure that 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’ll be able to signal as much as obtain an e mail alert for them right here.
Stakers who need to run by way of the improve course of extra instances earlier than mainnet are inspired to make use of ephemery.dev, which is able to 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’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?
Evaluate the EIPs included in Dencun to find out if and the way they have an effect on your challenge — 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.
The place can I observe the improve taking place?
The Goerli improve might be livestreamed right 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.
