It's here! All you need to know about the Ethereum Dencun Upgrade

March 13, 2024

Ethereum is on the verge of one of its most significant upgrades yet. This Wednesday, March 13th, the Ethereum mainnet will welcome the Dencun upgrade, an eagerly awaited event that promises to boost the network's scalability, efficiency, and security.

At Stakely, as experienced Proof-of-Stake network operators with a vast track record in validating Ethereum, we have been meticulously preparing for this moment, ensuring that our systems and clients fully benefit from the new improvements.

Below, we will delve into the details of the Dencun upgrade, the Ethereum Improvement Proposals (EIPs) that will be implemented, and how we at Stakely are facing this important event.

What is the Dencun upgrade and why is it important?

The Ethereum Dencun upgrade, a blend of the words "Cancun" and "Deneb," marks a milestone in Ethereum's journey towards greater scalability, security, and efficiency. Each Ethereum upgrade brings the potential to significantly improve the network's performance and functionality, and Dencun is no exception. Among the various EIPs included in this upgrade, some stand out for their potential impact on the Ethereum ecosystem.

Key improvements in the Dencun Upgrade

One of the highlights is the improvement proposed by EIP-6780, known as SELFDESTRUCT, addressing a long-standing issue: the prohibitive cost of deleting smart contracts. This improvement not only reduces costs but also incentivizes greater cleanliness and efficiency on the blockchain, which is crucial for its long-term sustainability.

Simultaneously, EIP-5656, known as MCOPY or Memory Copy Instruction, leads us to greater optimization in memory management, allowing more efficient copying and lower gas consumption. This subtle yet important improvement is a testament to Ethereum's constant quest for efficiency.

Another significant change comes with EIP-7044, introducing a mechanism for permanently valid exits. Moreover, this improvement allows exit credentials to be requested during the deposit process, ensuring that funds can be securely recovered, thus providing greater security for Ethereum's liquid staking protocols and allowing them to exit the validator if required.

Regarding EIP-7045, we see a focus on improving the accuracy and timeliness of attestations within epochs. This improvement allows late attestations to be penalized less severely, thus encouraging more consistent and fair participation from validators.

EIP-4788 is perhaps one of the most revolutionary improvements, as it allows for tighter integration between the execution layer and the consensus layer. By facilitating this communication, the need for external oracles for staking pools is eliminated, allowing for a more efficient and transparent distribution of rewards.

The implementation of EIP-7514 reflects a careful focus on the network's sustainable growth, limiting the number of validators that can enter each epoch. This considered approach to Ethereum staking not only keeps the network manageable but also ensures its growth is strategic and sustainable.

Last but not least, EIP-4844 introduces a revolutionary concept with its focus on "blobs" and proto-danksharding. By providing dedicated and temporary space for Layer 2 solutions, this improvement is a giant step towards a long-term scalability solution for Ethereum.

Each of these improvements, though unique in its purpose and application, shares a common goal: to prepare Ethereum for a brighter, more efficient, and scalable future.

What does the Dencun Upgrade mean for the Ethereum ecosystem?

Improvements in gas management, validator exit assurance, and transaction processing efficiency open up new possibilities for developers, users, and service providers like us at Stakely.

For the Ethereum community, these improvements mean not only a reduction in transaction costs but also a greater capacity to support a wider variety of decentralized applications and financial services without compromising security or decentralization. The introduction of blobs and the move towards proto-danksharding, in particular, are crucial steps towards a more robust and long-term solution to the network's scalability challenges.

Stakely's plans for the Dencun Upgrade

At Stakely, we have closely followed the development of the Dencun upgrade, applying the necessary software updates across our setup and maintaining constant communication with the protocols we work with. Our team has conducted thorough testing to ensure compatibility and operability of our services post-upgrade, ensuring a seamless transition.

Moreover, the impending shutdown of the Goerli testnet and the transition to the Holesky testnet are aspects we have addressed proactively, efficiently migrating our validators on Prater to Holesky.


The Dencun upgrade represents a significant moment for Ethereum and all those who are part of its ecosystem. At Stakely, we are proud to be at the forefront of this change and remain committed to providing the best possible service to our delegators and contributing to the continued growth and success of Ethereum.

We find ourselves at an exciting inflection point for Ethereum and blockchain technology as a whole. The Dencun upgrade not only improves the network in the present but also lays the groundwork for future innovations. At Stakely, we look forward to what's to come and are here to help our partners and delegators navigate this new chapter in the world of Ethereum.
