• Ethereum’s Fusaka upgrade is a smaller but efficient and powerful upgrade that achieves the effects of previous ones in a shorter time period.
• The upgrade implements Peer Data Availability Sampling (PeerDAS) to receive data from rollups without requiring node operators to upgrade their hardware or risk decentralization.
• Fusaka is expected to bring benefits to users, including less gas and fewer traffic jams, and is designed to be within the capabilities of consumer-grade devices.

Ethereum’s next Fusaka upgrade is a change of a very different kind from those long years of multi-step overhauls. In fact, Fusaka can be seen as a smaller but still very efficient and powerful upgrade that manages to achieve the all the effects of the previous ones in a much shorter time period. This method lets Ethereum decide quite cleverly what it wants and how fast it wants to deliver it.

What the Fusaka is All About

Fusaka is implementing one Peer Data Availability Sampling (PeerDAS) technique by which Ethereum receives data from rollups without the need for node operators to upgrade their hardware or risk decentralization.

Hence, the upgrade essentially addresses those aspects in the network that are not very warmly welcomed by the community and allows it to continue its march forward in the same manner. This upgrade complements the work done in the previous ones, Dencun and Pectra.

Interdependence

With the help of Fusaka, the fees are readjusted in such a way that the interconnection between layer 1 and layer 2 is not only preserved but also strengthened.

This equilibrium is very important since Layer 2 can only operate efficiently in an environment of cheap and safe Layer 1 services, whereas Layer 1 should also be fairly rewarded for the energy it has invested in providing the service.

Users would be the Primary Beneficiaries

If we are to believe the first indicators, nothing can be done to weigh against success in Fusaka’s case with less gas and fewer traffic-jamming reputable. The ability to eliminate data copies and the resulting reduction in congestion are key factors in the unfolding of these events.

Ethereum is securely scaling.

Security Considerations and Home Stakers

Fusaka was envisioned as an upgrade within the capabilities of consumer-grade devices. The extended testnet runs served as proof that increased blob capacity was not a silent factor that pushed out small operators.

Along with this, the long tail trend is expected to rapidly strengthen home stakeholders, and thus their participation would be enlarged in network security.

A Non-Flash Success

The extent of the Fusaka quiet success will be confirmed by it being less talkative and hence the rising frequency rather than the very brilliant headline numbers. The growing network will thus bring about not only more media reports of blobs achieving their targets but also more gas per block being ​‍​‌‍​‍‌​‍​‌‍​‍‌used
