Ethereum’s Fusaka Upgrade and L2 Cost Restructuring: The Next Phase of Ethereum Scaling

Another significant milestone towards the long-term scalability of Ethereum is the Ethereum Fusaka Upgrade. Following the Dencun upgrade that added rollup blob transactions, more and more Layer-2 deployments were witnessed on the network. Nonetheless, the developers soon realized that the current market in the form of blob fees enabled rollups to store the data of the transaction in Ethereum at a very minimal price.

The Ethereum Fusaka Upgrade proposes important modifications to address this imbalance and considerably improve the data throughput of Layer-2 networks. The two most common proposals circulating among Ethereum developers are EIP-7594 (PeerDAS) and EIP-7918, which redesign the way in which Layer-2 networks compensate for posting data to the Ethereum mainnet.

Fusaka is significant to crypto followers of the Ethereum roadmap since it matches scaling to economic sustainability. It increases rollup capacity and, at the same time, makes sure that the base layer of Ethereum preserves decentralization and security incentives.

Ethernet Fusaka Upgrade and Rollup Scaling Evolution.

Layer-2 rollups form the basis of the Ethereum scaling plan. Rollups do not execute transactions on the main chain but instead make transactions off-chain and post compressed data to Ethereum.

Such a strategy significantly saves money for the customers.

Nevertheless, rollups continue to use Ethereum in the two fundamental functions:

• Data availability
• Security settlement

Whenever rollups request Ethereum with transaction data, they are handled by a mechanism called “blob transactions” that is added during the Dencun upgrade in EIP-4844.

Blobs are used for data retrieval in verifying roll-up transactions. They enable Ethereum to be a universal layer of data availability without storing the data permanently on-chain.

The difficulty was when the prices of the blobs were brought down to very low levels at times when the demand was low. There were blocks that consumed the lowest charge of 1 wei to process blob data, which virtually rendered rollup data storage free.

It became a structural issue in the fee market of Ethereum. Source.

PeerDAS (EIP-7594): Scaling Data Availability without Hardware Scalability.

Peer Data Availability Sampling (PeerDAS) is one of the most significant aspects of the Ethereum Fusaka Upgrade.

The Full Data Downloading Issue.

Before PeerDAS, verifying data availability required the entire dataset of the blob to be downloaded by the validator. This requirement would soon be in need of more bandwidth and storage as the number of rollups increases.

In the long run, that may drive the network to centralized infrastructure providers.

To ensure that it is not centralized, it is important that the home stakeholders and independent validators can continue operating nodes without specialized hardware.

How PeerDAS Works

PeerDAS addresses this issue through sampling.

Rather than downloading all the data in the form of a blob, the nodes check the availability of data by sampling small parts of the data at random. Cryptographic assurances are such that in case these samples are present in the network, the complete data will also be present.

The major impacts of PeerDAS are:

• Validators obtain much less data.
• The bandwidth needs are reduced by approximately 80-85%.
• The network is accessible to smaller node operators.

This architecture guarantees that Ethereum will be scalable and remain decentralized.

Improvements in the Capacity of transactions.

PeerDAS also significantly boosts the size of the amount of data that can be processed by Ethereum in the form of blobs.

Upgrade: An upgrade by developers can increase the capacity of blobs up to eight times at the start, with further upgrades possible in the future.

This extra capacity is of direct benefit to Layer-2 networks, which include

• Arbitrum
• Optimism
• Base
• zkSync

The outcome of this for the user is a straightforward and less expensive transaction in rollups. Source.

EIP-7918: Reworking Ethereum Layer-2 Rent.

The second significant alteration of the Ethereum Fusaka Upgrade is in the aspect of economic incentives.

The Blob Fee Market Problem

Blob transactions have a market that is based on fees like the gas used in Ethereum. But the pricing force enabled the blob fees to be set at very low charges whenever there was low demand.

Since rollups rely on blobs to write their data, this provided a case where Layer-2 networks would be able to access the security layer of Ethereum, virtually free of charge.

Although this was positive in the short run, this model threatened to blow up Ethereum’s long-term economics.

Introducing a Fee Floor

EIP-7918 establishes a minimum price for the cost of blobs tied to the Layer-1 base fee of execution in Ethereum.

This process makes it impossible to bring down the prices of blobs to close to zero.

Instead, the system makes rollups remit a minimum price depending on the usage of the network.

The following objectives are met by this change:

• Regulates the market of Ethereum blob fees.
• Maintains equitable economic input of Layer-2 networks.
• Enhances ETH burn by blob transactions.

In the case of the Ethereum ecosystem, this essentially brings an ordered data usage rent model in Layer-2.

The Ethereum Fusaka Upgrade: Why the Ethereum Fusaka Upgrade is Important in the Long Term.

To Ethereum enthusiasts reviewing the Ethereum roadmap, the Ethereum Fusaka Upgrade is not just the usual technical adjustment.

It represents a more profound transformation in the network of triangulation of three rival priorities:

• Scalability
• Decentralization
• Sustainable economics

PeerDAS improves transaction capacity without any increment in hardware requirements. In the meantime, EIP-7918 will guarantee that the growing rollup ecosystem can make a reasonable contribution to the economic security of Ethereum.

All these developments bring Ethereum to the next stage of global adoption. Source.

Alternative Protocol Enhancements in the Ethereum Fusaka Upgrade.

Although PeerDAS (EIP-7594) and EIP-7918 are the most important in technical conversation, the Ethereum Fusaka Upgrade consists of a variety of other enhancements meant to make Ethereum stronger in both its execution tier and developer ecosystem.

These plans enhance the processing of transactions, cryptography, and stability of the networks. Combined, they make sure that Ethereum is capable of supporting the future expansion without compromising on decentralization.

Other additions are the most significant ones that concern the efficiency in execution and the infrastructural validation.

Increased Layer-1 Gas Limit

Among the most significant execution-layer enhancements of the Ethereum Fusaka Upgrade, there is the fact that it is proposed to raise the gas limit of Ethereum on Layer-1.

The upgrade includes an increase in the gas limit from approximately 30 million to approximately 60 million gas per block.

This modification will have the following advantages:

• Faster base throughput on the Ethereum mainnet.
• Better ability to perform complex smart contract operations.
• Less congestion in busy times on the network.

Even though the main scaling solution offered by Ethereum is Layer-2 rollups, scaling the Layer-1 gas limit enhances ecosystem resilience.

It comes in handy, especially with high-value DeFi activity that continues to run on the base layer of Ethereum.

Cryptographic Enhancements to Wallets of the Present Day.

The other interesting feature of the Ethereum Fusaka Upgrade is enhanced cryptographic support.

Previously, Ethereum had been depending on the secp256k1 cryptographic curve, which is common in blockchain systems. More recent hardware security solutions and mobile devices usually use a different cryptographic hash named secp256r1.

• Fusaka proposes support for this alternative cryptographic curve.
• Such a shift may open a bunch of significant changes:
• Wallet authentication using passkeys.
• Better support of hardware security modules.
• More simplified access to mobile biometric authentication.

It can eventually result in easier and more secure wallet experiences for the crypto user, particularly as Web3 applications start incorporating mainstream authentication technologies.

Improvements in Smart Contract Efficiency.

The Ethereum Fusaka Upgrade is also another improvement that brings new opcodes that make smart contracts more efficient.

These optimizations assist developers in optimizing the execution of contracts and minimizing the needless computation costs.

Practically, developers of decentralized applications can be advantaged by:

• Efficiency in contract execution.
• Less gas is used in some of its operations.
• More liberal smart contract architecture.

Although these changes are not so immediately attention-grabbing as scaling upgrades, they go a long way in enhancing the developer experience in the Ethereum ecosystem.

Ethernet Upgrade and Road to Danksharding.

The Ethereum Fusaka Upgrade is especially significant to long-term Ethereum adherents, as it gives the Ethereum network the final scalability architecture, Danksharding.

Danksharding tries to scale Ethereum data throughput by a significant amount to allow tens of thousands of transactions to be rolled up every second.

PeerDAS is at the heart of that vision.

Ethereum can scale data throughput by enabling nodes to check the availability of data using the sampling method instead of downloading the entire dataset, and it does not need costly equipment.

Using this technique allows the network to scale with a decentralized base of validators.

Ethereum developers anticipate that the size of blobs will increase in the future beyond the levels it is now at to dozens or potentially hundreds of blobs per block.

Such throughput would enable Layer-2 networks to handle huge global applications such as the following:

decentralized finance services.

• Blockchain-based gaming ecosystems.
• Decentralized AI infrastructure.
• Large-scale payment systems

Here, the Ethereum Fusaka Upgrade is an initial step to the greater-scale plan. Source.

Effect on the Layer-2 Ecosystem.

The rollup ecosystem has been developed tremendously in the last two years.

Millions of transactions are now processed daily on networks like Arbitrum, Optimism, Base, and zk-rollup platforms.

The Ethereum Fusaka Upgrade has a direct impact on interactions of these networks with Ethereum.

Advantageous Impact on Rollups.

PeerDAS is also very beneficial in terms of capacity to carry more data in the form of rollups per block.

This generates several benefits:

• Reduced rollup transaction costs.
• Increased transaction throughput.
• Enhanced scalability of applications that are decentralized.

L2 Networks’ Economic Adjustments.

Meanwhile, EIP-7918 is a more organized fee model.

Rollups are now going to pay a base price to utilize the Ethereum data availability layer. Although it will slightly raise the infrastructure expenses of certain networks, this will ultimately enhance the economic sustainability of Ethereum.

Notably, the change does not remove the cost benefits of the use of Layer-2 networks.

Rollup transactions are much less expensive than transacting them on the Ethereum mainnet.

Ethereum Upgrades Future.

The development plan of Ethereum lies outside of the Ethereum Fusaka Upgrade.

Future versions will be expected to be based on amendments made by Fusaka to enhance the scalability and development tools.

The possible areas of interest are:

• The additional capacity of the blobs increases.
• YAML enhancements to validator infrastructure.
• Additional optimization of execution layers
• Increased cross-rollup interoperability.

The other imminent upgrade that is in the negotiation stage is called “Glamsterdam,” which can bring in further performance and security upgrades.

To crypto followers who follow the long-term development of Ethereum, these upgrades show that the network is dedicated to making gradual and research-focused upgrades. Source.

Conclusion

The Ethereum Fusaka Upgrade is an extremely important milestone in the long-term scaling process of Ethereum.

The upgrade (introducing PeerDAS (EIP-7594) and EIP-7918) enhances the scalability of the Ethereum network and reorganizes the economic aspects between the network and the layer-2 networks at the same time.

The essential results of the upgrade are:

• Greater rollup capacity of blobs.
• Reduced bandwidth usage of validators.
• An even more eco-friendly fee structure for Ethereum.

Above all, the Ethereum Fusaka Upgrade positions the network to the next stage of the roadmap, with the full use of Danksharding and the adoption of Layer-2 in huge quantities.

To crypto believers, Fusaka is sending a message that the vision Ethereum had in trying to become the global settlement and data availability platform of decentralized applications is slowly coming into reality.
