Disclaimer: The Writer does not endorse and ask you to invest in anything without prior research and is not responsible for any damages. If you’ve been closely following the Ethereum community, you would've noticed that Ethereum has been due to drop their latest upgrade known as the “Dencun” Upgrade which will vastly reduce the amount of gas fees Ethereum has incurred at around 70$ or so for every single transaction that is over 60% higher as compared to 2023. We will be breaking down what this upgrade means for the network. Introduction The Ethereum “Dencun” Upgrade is a term coined from a constellation and the city of Cancun in Mexico following their general lexicographic way of coining these terms which is to combine the names of a constellation/star and a city in Mexico. The word “Dencun” is comprised of 2 words “Deneb”, the brightest star in the constellation of “Cygnus” and “Cancun”, a city in Mexico. This upgrade is set to drop in exactly 4 days aka the 13th of March after its initial announcement from the Ethereum Foundation on the 27th of February this year. This upgrade marks the beginning of the “Surge” Era in the Ethereum ecosystem which will include a lot more improvements in terms of the network’s security, scalability, and efficiency. This upgrade is one of the main key factors in addressing the popular problem of the [let me know if you want an article on this from me], and it will be deployed on the Main-net of the Ethereum blockchain network on the March 13th of this month. Blockchain Trilemma This upgrade will include major patches addressing scalability and security issues through the various number of suggestions received through the Ethereum Improvement Proposals [EIPs] and will be focusing on implementing “Proto-DankSharding” which is notably known as the “EIP-4844”. And, this EIP is crucial for lowering the high amounts of gas fees that are being noticed across the network and enhancing network scalability. The Core of This Upgrade This upgrade is the next major upgrade after the “Shapella” Upgrade that took place in the year 2023 was a hard fork upgrade [more on this later] and this upgrade enhanced security by improving network protocols and adding trust over time through continued staking support. It combines changes to the Shanghai Ethereum Virtual Machine and the Capella consensus layer, introducing new functionality and Ethereum Improvement Proposals (EIPs). Now, coming back to the current “Dencun” Upgrade, let’s understand the core components being upgraded and the crux of this upgrade as a whole. This upgrade promises to fix existing shortcomings [not all] like addressing scalability and security issues and more and takes the Ethereum network as a whole one step closer to making the network much more resilient while maintaining low gas fees and high security. The Ethereum Dencun upgrade, scheduled for deployment on March 13, 2024, marks a significant milestone in Ethereum's roadmap, focusing on scalability, efficiency, and security enhancements. This upgrade is part of the " " era in Ethereum's development, aiming to address the blockchain trilemma by improving network performance while keeping costs low. The core of the Dencun upgrade revolves around several Ethereum Improvement Proposals (EIPs), with EIP-4844 for proto-dank sharding being a notable highlight. Surge This proposal aims to optimize gas fees and enhance network scalability by introducing a concept called " ," which is designed to decrease transaction costs for layer-2 blockchains and reduce data availability costs, addressing key scalability challenges and also explore future advancements that have been highly anticipated by stakeholders of this project. proto-dank sharding Proto-dank sharding lays the groundwork for the eventual implementation of " ," which aims to further extend these benefits. The upgrade also introduces 'blobs,' a technical innovation designed to lower the cost associated with rollups on the Ethereum mainnet by compressing transaction data off-chain, thereby reducing storage and processing requirements. store data temporarily, which is necessary only for short-term transaction verification, allowing for its eventual deletion to prevent network overload. Secure and efficient data handling is ensured through cryptographic commitments that detect any data alterations. dank sharding Blobs The Dencun upgrade is expected to significantly increase Ethereum's transaction processing capacity, potentially enabling the network to handle more than 100,000 transactions per second. This enhancement is crucial for Ethereum's ability to support a growing ecosystem of decentralized applications (dapps) and users. The upgrade combines changes to both Ethereum's consensus and execution layers, with a full list of protocol changes specified in . These changes include for transient storage opcodes, EIP-4788 for beacon block root in the EVM, for shard blob transactions, and others aimed at improving the network's functionality and efficiency. EIP-7569 EIP-1153 EIP-4844 For stakes and node operators, it's essential to update their node's execution and consensus layer clients to the versions listed in the upgrade announcement to be compatible with the mainnet Dencun upgrade. Failure to do so will result in being stuck on an incompatible chain following the old rules and being unable to send Ether or operate on the post-Dencun Ethereum network. In summary, the Dencun upgrade represents a significant step forward in Ethereum's development, focusing on enhancing scalability, efficiency, and security through various EIPs, including the introduction of proto-danksharding and blobs. This upgrade is expected to significantly impact Ethereum's transaction processing capacity and reduce transaction costs, making it a pivotal moment in the Ethereum ecosystem's evolution. Taking a Step Back and Understanding the Fork Process Now, you guys may be wondering what the heck a “Fork” even is and it is crucial to understand the logic behind this word and why Blockchain networks need to make upgrades to a forked version and understand the implications this has both on Dapp Developers and holders of the Tokens in circulation on the Ethereum blockchain. First, let’s cover what a Fork is. A "fork" in the context of blockchain technology refers to a divergence in the blockchain protocol, leading to two separate paths that can run independently of each other. This can occur for various reasons, such as disagreements over protocol changes, security vulnerabilities, or the introduction of new features. Forks are a natural part of the evolution of blockchain networks, allowing for experimentation and innovation without compromising the integrity of the original blockchain. Assume it is similar to the forking of a GitHub repository where you can make your own changes while the main repository remains uninterrupted and unchanged in nature. It is crucial to understand why forking is performed on a blockchain network, a blockchain network despite being decentralized still has developers making changes to it, and similar to the traditional SDLC lifecycle in general, a release cycle is followed in this case as well with a lot of care and it is crucial that the blockchain network does not go down as thousands of transactions and validation of these transactions along with the release of a lot of smart contracts happen every single second on a network as vast as Ethereum and it cannot go down at any cost. So, to prevent the network from going down and considering the difficulty in the bug fix process that has to be undertaken for blockchain networks as compared to traditional software where the changes once made are reflected very quickly, a fork takes place where all of the required changes are performed on the network like the upgrades, etc and all of the previous assets are automatically moved from the old network to the new fork and the old network is now replaced by the new network. Even though slightly risky, your coins should get converted over to the new Ethereum forked blockchain after the upgrade without any form of action being required from your end and the same also applies for the smart contracts or Dapps that were previously running on the older blockchain version. Now, let’s break down and understand the fork process in a decentralized network - : Forks can introduce new features or changes that affect how decentralized applications (dapps) operate. Developers need to be aware of these changes to ensure their dapps remain functional and secure on the new fork. This might involve updating smart contracts, adjusting transaction handling, or even redesigning parts of the application to take advantage of new features. For Dapp Developers : Forks can lead to the creation of new tokens or changes in the value of existing tokens. This can affect the liquidity, trading volume, and overall market dynamics of the tokens in question. Token holders need to understand the implications of a fork on their holdings, including potential changes in tokenomics, governance, or utility. For Token Holders : Ethereum, like many other blockchains, has undergone several forks to introduce new features, improve security, and scale the network. These forks are carefully planned and executed to ensure a smooth transition for the network's participants. The Ethereum community, including developers, miners, and users, plays a crucial role in the fork process, from discussing proposals to participating in the upgrade. For the Ethereum Network The Dencun upgrade, for example, is a significant Ethereum improvement designed to address scalability issues and reduce transaction costs for Ethereum Layer 2 solutions. It introduces several Ethereum Improvement Proposals (EIPs), including , which aims to improve data storage and reduce costs by introducing a new data storage structure called "blob" for storing transaction data submitted from Layer 2 to Layer 1. This upgrade is part of Ethereum's ongoing efforts to evolve and improve the network, highlighting the importance of understanding and adapting to forks in the blockchain ecosystem. EIP-4844 In summary, a fork is a critical aspect of blockchain technology that allows for innovation and improvement. and it is crucial and also a mandatory requirement for Dapp developers and token holders to stay informed about forks and their implications, as they can significantly affect the operation and value of their applications and holdings. The active participation in the fork process, including the Dencun upgrade, demonstrates the network's commitment to continuous evolution and improvement and they in general inform at least weeks in advance of any new upgrades coming to the network very soon and initial announcements are made months or years prior to the upgrade. Ethereum community's Finally, you may be wondering why the tends to notify users about major upgrades only weeks ago. This is because in the case of blockchain networks in general when they announce an upgrade they would pretty much be ready to push out a stable release on the day they could but the week’s delay is to make sure that this critical upgrade doesn’t have any flaws in it as these upgrades can be the make or break of both the Dapps and the tokens as a part of the network and can sometimes if not done correctly wreak havoc on the reputation that the particular blockchain has built up. Ethereum Foundation Major Components of this Upgrade This upgrade includes major improvements affecting multiple components of the Ethereum blockchain network and we will be covering a list of the major components that have been upgraded during this upgrade process and how they solve different problems that have been affecting the network so far.

What in the world is “Proto-Danksharding”? Let’s cover the most awaited part of this upgrade known as the Proto Danksharding feature and cover its technical aspects in an easy-to-understand way. Imagine you have a magical toy box that can hold all your favorite toys. But this toy box is special because it can also share its toys with your friends. Now, imagine if you could put some of your favorite toys in a special drawer inside this toy box. This drawer is not just for you; it's also for your friends. And the best part is, after a certain time, the toys in this drawer go away, and the drawer is ready for new toys. This way, you and your friends can always find new toys to play with, and the drawer doesn't get too full or messy. Now, let's translate this story into the world of Ethereum and proto-danksharding. Proto-danksharding is like the special drawer in our magical toy box. It's a new way for Ethereum to handle transactions and data. Instead of keeping all the data and transactions in the main part of the toy box (the Ethereum blockchain), it puts some of them in this special drawer, called "blobs." These blobs are like the toys in our special drawer; they can be shared and used by everyone, but they're not forever. After a certain time, the blobs go away, and the drawer is ready for new blobs. This makes the Ethereum network more efficient and cheaper to use because it doesn't have to keep all the data and transactions in the main part of the blockchain all the time. Now, let’s cover the technical details of it : : In the Ethereum network, are temporary storage units for data. They are designed to store transaction data off-chain, reducing the load on the main Ethereum blockchain. This is similar to how our special drawer in the toy box reduces the number of toys that need to be stored in the main part of the box. Blobs blobs : The key feature of blobs is that they are temporary. This means that data stored in blobs is not permanent. After a certain period, the data is removed, making room for new data. This is akin to how our special drawer in the toy box is always ready for new toys after the old ones are taken out. Temporary Storage : By offloading transaction data to blobs, Ethereum can handle more transactions per second without overloading the network. This is because the main blockchain doesn't have to process all the data and transactions, making the network more efficient and scalable. Efficiency and Scalability : Since blobs store data off-chain, they reduce the cost of transactions. This is because the network doesn't have to spend resources to store and process all the data on the main blockchain. This is similar to how our special drawer in the toy box makes it cheaper to play with new toys. Cost Reduction In summary, proto-danksharding, with its concept of blobs, is a significant step forward in making Ethereum more efficient, scalable, and cost-effective. It's like having a special drawer in our magical toy box that makes it easier and more fun for everyone to play with their favorite toys. How does Proto Danksharding Differ from Normal Sharding in the Network Proto-Danksharding and traditional sharding in Ethereum represent two different approaches to improving the scalability and efficiency of the network. Let's break down how they differ and their significance. Traditional Sharding Traditional sharding is a well-established concept in blockchain technology. It involves dividing the blockchain into smaller, parallel chains called shards. Each shard can process transactions and smart contracts independently, which can significantly increase the network's capacity to handle transactions concurrently. This approach is effective in enhancing scalability but can introduce complexities, such as the need for multiple block proposers to validate transactions across different shards. Proto-Danksharding Proto-Danksharding, introduced as part of the Ethereum Cancun upgrade through EIP-4844, serves as a foundational step towards achieving full danksharding. It introduces some of the essential elements of danksharding in a more straightforward manner, allowing for quicker integration with the current Ethereum framework. Unlike traditional sharding, proto-danksharding introduces a more efficient system that moves beyond the limitations of conventional blockchain divisions. One of the key innovations of proto-Danksharding is the concept of "blobs" for data availability. Blobs are temporary storage units for data, designed to store transaction data off-chain. This reduces the load on the main Ethereum blockchain, making the network more efficient and scalable. Proto-Danksharding also focuses on reducing gas fees, particularly for layer-2 solutions, by allowing rollups to add cheaper data to blocks through "blob-carrying transactions." Key Differences : While both aim to improve scalability, danksharding is an advanced version that aims to make Ethereum truly scalable, with the potential to handle more than 100,000 transactions per second. Proto-Danksharding, on the other hand, is an intermediate step toward achieving this goal, with an expected range of 100-10,000 transactions per second. Scalability Goals : Danksharding requires multiple protocol upgrades and is still in development. Proto-Danksharding implements EIP-4844, allowing for a more straightforward integration with the current Ethereum framework. It's being prototyped and is an interim step towards full danksharding. Implementation Complexity : Danksharding introduces a singular block proposer system, eliminating the complexities of multiple proposers found in standard sharding. Proto-Danksharding focuses on introducing "blob-carrying transactions" to reduce gas fees and is compatible with rollups for off-chain transaction processing. Transaction Types In summary, proto-Danksharding is a foundational step towards achieving full danksharding, introducing innovative concepts like blobs for data availability and focusing on reducing gas fees. It represents an intermediate solution that sets the stage for the eventual implementation of danksharding, which aims to significantly enhance Ethereum's scalability and efficiency. What Are Blobs and What Significance Do They Have in the Ethereum Blockchain? Blobs, or binary large objects, are large data packets that are distinct from regular Ethereum call data. They are designed to handle large amounts of data more efficiently than traditional transactions. Blobs are stored off-chain and referenced in transactions, making them a significant innovation in Ethereum's data-handling capabilities. They are technically vectors of data represented as polynomials, which allows for simple cryptographic referencing and verification. This approach is crucial for Ethereum's scalability and efficiency, as it enables the network to process and store more data without overburdening the main blockchain. Blobs are essential for several reasons: : By offloading data to blobs, Ethereum can handle more transactions per second without overloading the network. This is particularly beneficial for layer-2 solutions, which can batch multiple transactions into one to be processed on Ethereum, significantly reducing operational costs and improving scalability. Scalability : Blobs reduce the cost of transactions by storing data off-chain. This makes Ethereum more accessible and cost-effective for developers and users. Cost Reduction : By increasing the amount of data that can be included in a block without overburdening the network, blobs lead to an overall increase in network throughput. This allows Ethereum to accommodate more transactions, users, and dApps alike. Network Efficiency The introduction of blobs in the Ethereum network through the Dencun upgrade is beneficial for several reasons: : Blobs enhance the throughput and efficiency of Layer 2 solutions, making Ethereum more scalable and efficient. Improved Data Handling : By making Beacon Chain's block roots accessible to the Ethereum Virtual Machine (EVM) through EIP-4788, Ethereum can reduce its reliance on external oracles, enhancing its decentralization and security. Reduced External Dependence The Dencun upgrade introduces two new EVM opcodes related to blobs: : This opcode allows a transaction to include a reference to a blob, enabling the storage of large data packets off-chain. BLOBSTORE : This opcode enables accessing the data within the blob, allowing transactions to retrieve and use the data stored in blobs. BLOBLOAD Key Features of Blobs : Blobs are committed to using KZG, a new form of vector commitment scheme that is compatible with future data-availability sampling, which is crucial for full danksharding. KZG Commitments : Blobs are pruned regularly in beacon nodes, reducing storage burden and enabling cheaper pricing compared to permanent CALLDATA. Pruning : Blobs cannot be read by contracts and are invisible to the EVM, maintaining network integrity and reducing the burden on the execution layer. EVM-invisibility In summary, blobs represent a significant advancement in Ethereum's data handling capabilities, offering scalability, cost reduction, and improved network efficiency. The introduction of blobs through the Dencun upgrade, along with new opcodes like BLOBSTORE and BLOBLOAD, enhances Ethereum's ability to process and store more data, making it more accessible and cost-effective for developers and users.

Security Enhancements The Dencun upgrade, part of Ethereum's roadmap towards achieving mass scalability and efficiency, introduces several security enhancements that are crucial for safeguarding the network and its users. These enhancements are designed to address potential vulnerabilities and ensure the integrity and security of the Ethereum ecosystem. 1. KZG Commitments for Data Integrity One of the key security enhancements introduced by the Dencun upgrade is the use of for maintaining the integrity of off-chain blob data. KZG commitments are cryptographic tools that allow for efficient verification of data integrity without revealing the actual data. This mechanism is vital for ensuring that off-chain blob data remains tamper-proof and trustworthy. By utilizing KZG commitments, the Dencun upgrade enhances security by ensuring that data stored in blobs, which are temporary storage units for data, remains secure and unaltered. KZG commitments 2. Proactive Security Measures The Ethereum community is encouraged to anticipate potential security vulnerabilities and proactively address them. This includes measures against attacks, where an attacker could create multiple identities to gain control over a significant portion of the network's resources, and Denial-of-Service (DoS) attacks, where attackers attempt to overwhelm the network with excessive transactions or requests. Implementing mechanisms to detect and prevent these attacks is crucial for maintaining network stability and availability. Sybil 3. Collective Responsibility for Security Security is a collective responsibility within the Ethereum community. All node operators are urged to adhere to best practices for secure node operation, including regularly updating node software, implementing proper access controls, and monitoring for suspicious activities. These practices help prevent unauthorized access to nodes and detect any unusual behavior or potential security breaches. In summary, the Dencun upgrade introduces several security enhancements, including the use of KZG commitments for data integrity and proactive measures against potential attacks. These enhancements, along with the collective responsibility for security within the Ethereum community, aim to create a more robust and secure upgraded network. By focusing on continuous improvement in security, the Ethereum network can better protect itself against vulnerabilities and ensure the safety and trustworthiness of its users. Staking Process Improvements introduced by this Upgrade The Dencun upgrade introduces several improvements to the staking process on Ethereum, aiming to enhance the overall experience for stakers and validators. These enhancements are designed to make the staking process more flexible, secure, and efficient, addressing key areas such as voluntary exits and attestation inclusion times. EIP-7044: Simplifying Voluntary Exits EIP-7044 focuses on streamlining the process of voluntary exits for stakers. In the current Ethereum Proof of Stake (PoS) model, stakers can earn rewards by locking up 32 ETH and participating in the network's security. For those who prefer not to manage the technical aspects of being a validator, delegated staking allows them to stake their ETH through a third party while retaining control over their assets. However, exiting staking with a specific validator previously required a pre-signed exit message, which relied on trust. EIP-7044 aims to address this by making exit messages permanent, providing more security and peace of mind for stakers. This improvement is crucial for enhancing the staking experience by making the process of exiting staking more straightforward and secure. EIP-7045: Extending Attestation Inclusion Time EIP-7045 seeks to improve the efficiency and competitiveness of the Ethereum network by extending the attestation inclusion time. In the PoS model, for a block to be considered official, it needs validations or attestations from validators. However, validators have a limited time window to submit these attestations. EIP-7045 proposes to significantly extend this period, allowing more validators to earn rewards and speeding up the confirmation of blocks on the blockchain. This change is expected to make the network more efficient, as it reduces the time validators need to wait to submit attestations, thereby increasing the overall speed and reliability of the network. These improvements to the staking process have several benefits: : By making exit messages permanent with , stakers can have more confidence in their ability to exit staking without relying on the trust of a third party. This enhances the security of the staking process. Enhanced Security EIP-7044 : The extension of attestation inclusion time through allows for a more efficient network, as it reduces the time validators need to wait to submit attestations. This can lead to faster block confirmations and a more responsive network. Increased Efficiency EIP-7045 : For both stakers and validators, these improvements aim to make the staking process more user-friendly and efficient.
