What is Dencun Upgrade?

The Dencun Upgrade is all about making the Ethereum network better when it comes to handling data.

It’s going to make transactions quicker and cheaper. This is a big deal because, as many of you know, paying a lot for transactions has been a big headache for both users and developers using Ethereum.

This upgrade is more than just a small tweak. It’s a major effort to improve how Ethereum deals with data. By making data storage and processing better, Dencun will help cut down the costs of transactions. This is super important for everyone using Ethereum.

Also, the upgrade is going to make the network faster and more “pleasant” to use. Quicker transactions mean a smoother experience.

This could really shake things up, maybe even bringing in more businesses that were hesitant before because of the slowness and high costs.

Dencun’s Ethereum Improvement Proposals

As you examine the Dencun upgrade, it’s important to focus on its Ethereum Improvement Proposals (EIPs). These EIPs are set to improve Ethereum’s functionality, security, and scalability.

Below is a table summarizing the key proposals and their potential impacts on the network.

EIP NumberProposal FocusImpact on Ethereum
EIP-7514Gas Cost ReductionImproves transaction efficiency
EIP-1153Transaction OrderingBoosts network throughput
EIP-4788Smart Contract Size LimitsExpands smart contract capabilities
EIP-4844Data ShardingScales data processing
EIP-6780Security EnhancementsStrengthens network security
EIP-5656Memory EfficiencyData can move faster
EIP-7044StakingEasier Un-staking
EIP-7045Cheaper Transaction FeesBetter understanding of transaction fees


EIP-7514, also known as ‘The Gatekeeper,’ helps control how many new validators can join the Ethereum network.

It sets a limit of eight new validators at a time.

This is like making sure a party doesn’t get too crowded by only letting a few people in at a time.

If too many people became validators all at once, it could slow down the network, making it hard for transactions and operations to happen smoothly.


EIP-1153 is a big update for Ethereum that brings in something called transient storage to help make things run better and cut down on costs for everyone using it.

Think of it like adding a special temporary memory space to Ethereum’s system, which is kind of like the memory in your computer.

This new feature lets transactions on Ethereum use two new commands, TLOAD and TSTORE, making things more efficient.

This is a bit like having an organized way to handle ingredients in a kitchen. With transient storage, we’re making sure that we’re not keeping unnecessary data around, which helps keep everything running smoothly.

This update is a big deal because it helps Ethereum handle more activity without slowing down or getting too expensive. It’s like making the whole system more streamlined and cost-effective for users.


EIP-4788 is an update that makes Ethereum work better by creating a direct link between its main parts, making it safer and more efficient for apps to run. Think of Ethereum like a big system where moving data quickly is key.

Before, if data moved slowly, it would be like traffic jams slowing everything down. But now, with something called the ‘lighthouse block root,’ it’s like having a fast track that directly connects these parts.

This means apps, especially those that deal with staking, can work more smoothly and quickly.


EIP-4844 builds on what EIP-4788 started. It adds something called blob-carrying transactions that help Ethereum run better and reduces network traffic jams. Think of Ethereum like a busy place where every transaction is like adding another plane to an already crowded airport.

The blobs in EIP-4844 are like small, efficient containers that work together with the usual transactions to help clear up the congestion. Mainly, the people who organize transactions in Ethereum’s Layer 2 rollups use these blobs. They help make transactions go through faster and smoother without going against Ethereum’s goal of staying decentralized.

In short, it’s like adding more lanes to our airport analogy, improving how many transactions Ethereum can handle and making your experience on the blockchain more smooth and dependable.


EIP-6780 is like a new rule for Ethereum that makes it safer by controlling how the SELFDESTRUCT function is used. Think of Ethereum like a playground where smart contracts are like kids playing with LEGO. Before, any ‘kid’ could just break what others made, which could cause a lot of mess.

EIP-6780 changes that by making sure that only the ‘kid’ who built something with SELFDESTRUCT can take it apart. It’s like giving each kid their own box to keep their LEGO safe. This way, everything stays more organized and secure, making it a better place for everyone who’s building and using stuff there.


EIP-6780 works on making things safer by controlling how the SELFDESTRUCT function is used, but EIP-5656 brings a big improvement in how efficiently Ethereum can use memory with something called the MCOPY instruction.

This is really important for how Ethereum’s Virtual Machine (EVM) works.

In simple terms, MCOPY makes it much easier and faster to move data around in Ethereum’s memory. This is a big deal because it helps transactions get processed faster.

Before EIP-5656 came along, moving data in the EVM could be slow and a bit like doing a tedious job by hand.

But with MCOPY, it’s like Ethereum got a major upgrade with better tools for handling data.

This doesn’t just make things faster; it also helps save on costs and allows the network to handle more activity. This is great news for everyone using Ethereum.


EIP-7044 is like a special pass for people who stake their money into Ethereum, making it easier for them to un-stake or take their money out whenever they want. Think of Ethereum’s money-putting system as a big show.

Usually, trying to un-stake your tokens could be really confusing, like trying to find your way out of a backstage area full of twists and turns.

But EIP-7044 changes that by giving out these special passes that don’t run out, letting people leave smoothly whenever they decide.

This change takes away the stress of deciding the right time to leave and the worry about missing the chance to do so, making the whole process friendlier for everyone.

By allowing people to say they want to leave anytime and having that choice stay valid no matter what, it makes sure no one is stuck, no matter how things change behind the scenes.

It’s a step towards making Ethereum’s staking system easier and open for everyone to join in.


EIP-7045 is like a helper for validators, giving them more time to check and approve blocks. This makes the Ethereum network work faster and more smoothly.

Think of it as giving someone extra time to pass a baton in a race, making sure they do it right without having to rush. This change helps the network deal with a lot of activity better, making it stronger and more dependable.

It’s about making sure the system can handle more without getting bogged down, ensuring it runs well and stays stable.


EIP-7516 is a new update for Ethereum that makes things work better and smoother. It adds a special tool called BLOBBASEFEE.

Think of Ethereum like a busy market. Before this update, figuring out how much to pay for transactions was like guessing.

Now, with BLOBBASEFEE, it’s like everything has a clear price tag.

This tool helps make things quicker and easier, especially for advanced Ethereum features like rollups and layer 2 solutions.

It helps manage the network’s resources better. With this update, transactions become quicker, more straightforward, and fairer for everyone. Overall, EIP-7516 makes using Ethereum a lot better.

About Ethereum

Ethereum is a leading platform for decentralized apps, changing the way we think about online transactions and contracts.

Essentially, Ethereum is more than a type of digital money. It’s a system built on blockchain technology that lets developers create and run smart contracts and decentralized applications (DApps) without needing middlemen.

Instead of using centralized systems controlled by one authority, Ethereum works on a worldwide network of computers.
