Since its creation, Ethereum has been at the vanguard of the blockchain’s evolution. As a groundbreaking smart contract platform, Ethereum’s journey from the founder of decentralized applications to the center of its current state has injected new energy into its functionality and scalability with each upgrade. The latest evolution is reflected in the Ethereum Cancun upgrade, a transformative development plan scheduled to launch in the first half of 2024. The upgrade introduces proto-danksharding technology and implements other important improvements, marking a pivotal moment for Ethereum. This upgrade will significantly increase scalability, reduce transaction costs, and improve network efficiency, further solidifying Ethereum’s position as a leading and innovative blockchain platform.
The Essence of Ethereum’s Cancun Upgrade
The Ethereum Cancun-Deneb (Dencun) upgrade marks an important development phase for the Ethereum network. This upgrade is a complex and comprehensive hard fork designed to address the pressing challenges facing the Ethereum blockchain, especially in terms of scalability and efficiency. The core of the Cancun upgrade is the introduction of a series of Ethereum Improvement Proposals (EIPs) that will collectively improve network performance and user experience.
An important part of the upgrade is proto-danksharding, introduced by EIP-4844, which uses a breakthrough sharding method. Sharding is a method of dividing a blockchain into smaller, more manageable pieces, or “shards,” each capable of processing transactions independently. This partitioning allows for parallel processing, significantly increasing the capacity and efficiency of the network.
Of particular note is the fact that proto-danksharding is a transitional step towards full-scale danksharding. It introduces transactions carrying blobs that will temporarily store and retrieve off-chain data. This approach is expected to significantly reduce gas fees and increase transaction throughput, bringing Ethereum closer to the ability to manage global transaction network capacity.
Another key aspect of the Cancun upgrade is Ethereum’s transition from Proof of Work (PoW) to Proof of Stake (PoS). This strategic change will make Ethereum a more energy-efficient and scalable blockchain. Unlike PoW, PoS selects validators to create new blocks based on the amount of cryptocurrency they hold and the amount of currency they are willing to "stake" as collateral, rather than relying on energy-intensive mining. This transformation not only significantly reduces the energy consumption of the network, but also provides the possibility for more efficient and secure sharding. In a PoS system, validators are randomly assigned to specific shards, helping to prevent manipulation and improve the overall performance of the network.
Key features introduced in the Cancun upgrade
The Ethereum Cancun upgrade is a comprehensive update that introduces several key features, each of which will enhance the network's performance and user experience. The core of the upgrade includes the introduction of proto-danksharding and blob-carrying transactions, as well as other important Ethereum Improvement Proposals (EIPs).
Proto-danksharding marks a step towards full danksharding, as described in EIP-4844, an innovative approach to sharding that aims to increase the scalability and efficiency of the network.
Danksharding is an advanced sharding technology for the Ethereum blockchain that strives to significantly improve its data throughput and transaction processing efficiency. It enables parallel transaction processing by dividing the blockchain into smaller fragments, or “shards,” thus greatly increasing the network’s scalability.
Unlike traditional sharding methods, proto-danksharding introduces a more unified approach. It allows large data "blobs" to be temporarily stored on the network, thereby increasing data throughput without overburdening the blockchain.
This approach significantly increases the network’s ability to process transactions and is expected to expand Ethereum’s transaction processing speed to approximately 100,000 transactions per second. This will make Ethereum more attractive and provide users with a more efficient and practical blockchain experience.
Transactions with Blobs
Transactions carrying blobs are a new type of transaction introduced by Proto-danksharding. These transactions can carry large amounts of data (blobs), up to 128 KB in size, at a lower cost than standard transaction data.
Blobs are temporarily stored on the Ethereum consensus layer, which means they are not a permanent part of the blockchain. This temporary storage can significantly reduce gas fees for transactions involving large amounts of data.
By enabling more efficient data storage and retrieval, transactions carrying blobs are expected to reduce the cost of layer 2 rollups, making Ethereum more accessible and cheaper for users.
Benefits of upgrading
The Ethereum Cancun upgrade is poised to bring multiple benefits to the Ethereum network, addressing some long-standing challenges and setting new standards for blockchain technology. The main benefits of this upgrade include improved scalability, lower transaction costs, optimized data management, enhanced security, and better cross-chain communication.
Improve scalability and transaction speed
One of the most obvious benefits of the Cancun upgrade is the significant increase in scalability. By implementing proto-danksharding, the network's ability to process transactions is expected to increase significantly. This enhancement means that Ethereum can handle more transaction volumes at a faster rate, reaching 100,000 transactions per second.
The upgrade helps improve the efficiency of data processing and storage, allowing the network to handle increased load without affecting performance. This scalability is critical in Ethereum’s long-term goal of supporting a global user base and enabling a wide range of decentralized applications.
Reduce transaction costs and optimize data management
The blob-carrying transactions introduced in proto-danksharding by this upgrade have greatly reduced the cost of storing large amounts of data on the Ethereum blockchain. Gas fees have also been reduced, making transactions more affordable, especially for operations involving complex smart contracts or large amounts of data transfer.
By temporarily storing blocks of data, the upgrade optimizes data management, ensuring that the Ethereum blockchain is not permanently burdened with large amounts of data. This approach not only reduces costs but also improves the overall efficiency of data processing on the network.
Enhanced security and cross-chain communication
The Cancun upgrade includes multiple EIPs that enhance the security of the network. For example, EIP-2929 increases the gas cost of certain operations, making potential attacks more expensive and less attractive to malicious actors.
The transition to a Proof of Stake (PoS) consensus mechanism is also part of Ethereum’s broader upgrade strategy. It also enhances the security of the network. Compared to Proof of Work (PoW), PoS is seen as a more secure mechanism against certain types of attacks because it requires validators to have a financial stake in the network.
Another benefit of this upgrade is enhanced cross-chain communication.
