An interview about the new network updаte
Interviewer: Earlier you mentioned that major Ethereum upgrades are released about twice a year. What is this updаte called Fusaka?
Expert: Fusaka is another major upgrade to the Ethereum protocol. Its main focus is scaling the network and making life easier for Ethereum users. The updаte unlocks new possibilities for L-rollups and L2 solutions, significantly increasing the overall scalability of the systеm (1). At the same time, Fusaka brings important innovations in two more directions: improving the user experience and further developing scalability at the base L1 layer (2).
Interviewer: So this is no longer just an experiment?
Expert: Exactly. This is not a trial run, but the next inevitable step in evolution. Fusaka will make it possible to onboard as many people as possible to Ethereum without distorting the original idea of the network. We do not intend to sacrifice decentralization for the sake of scaling (3). Security remains the key priority. Ethereum will become both more scalable and more secure at the same time. And the benefits of this scaling will be felt on both L1 and L2.
Interviewer: Could you go into more detail on what the Eardust technology is?
Expert: Within Fusaka we are indeed introducing a fundamentally new solution — the Eardust technology. Increasing the data capacity means having more “blobs”, which expands the network’s capacity for rollups (4). Right now, data volume and data processing are the main bottleneck for rollups in the Ethereum ecosystem. If we can ease this constraint, it will open up far more room for everything being built on top of Ethereum. The data at the DA level itself provides strong guarantees of censorship resistance (5).
Interviewer: And how will this affect the user experience?
Expert: In this upgrade we are introducing a set of features that significantly improve UX (6). In particular, adding an L1 curve makes it possible to use secure user devices such as mobile phones. This allows users to authenticate via fingerprint, including through the use of passkeys (7), which arrive directly on Ethereum L1. This is extremely important because it reduces friction when onboarding new users to non-custodial wallets (8). Thanks to this, developers will be able to design a simple and intuitive end-to-end user journey without compromising on security.
Interviewer: What other improvements does Fusaka inсlude?
Expert: In addition to that, there are a number of extra changes, including increasing block sizes and transaction limits (9). This makes it possible to raise the gas limit (10), which means increasing the number of transactions the network can process while still keeping fees very low. All these measures are aimed at creating an environment where the entire Ethereum ecosystem can scale: it remains reliable, strives for 100% uptime, and is capable of processing operations at high speed.
Interviewer: What comes next?
Expert: Our work is far from done. Fusaka will make Layer 2 truly scalable, close this chapter and open the next one, where we will focus on scaling L1. Essentially, we are only just entering the era of scaling. I’m very excited about the changes ahead — now is the perfect time to plug into the ecosystem. We will be scaling L1, scaling L2, and at the same time making the user experience simpler and more convenient.
Footnotes
- L-rollups and L2 — like high-speed highways for transactions on the Ethereum network, where far more operations can be processed in less time.
- L1 — the main “road” of Ethereum, the base protocol layer where all transactions are ultimately finalized and stored.
- Decentralization — a way of organizing the network where there is no single owner: decisions are made collectively, and no one can unilaterally rewrite the rules.
- Blobs — large chunks of data that make it possible to process big volumes of transactions in parallel.
- DA (Data Availability) — a guarantee that all data is available and stored reliably so it can’t be hidden or silently altered.
- UX (User Experience) — everything that affects how easy, clear and pleasant it is for a person to use Ethereum and applications built on top of it.
- Passkeys — “magic keys” that rеplace passwords, stored on your phone and used to securely access your wallet.
- Non-custodial wallet — a wallet where only you control your funds, and not a third-party company or service.
- Block size and transaction limits — like widening a road and increasing the number of cars that can drive on it at the same time.
- Gas limit — similar to a “fuel tank” for transactions: the higher the limit, the more operations can be included in a block and processed at once.
