The next is a visitor submit and opinion of Rostyslav Bortman, Founding father of Ethereum Ukraine.
Even in wartime Kyiv, innovation doesn’t pause. At ETHKyiv 2025, greater than 100 hackers proved it—transport privacy-first dApps, competing for grants, and displaying what’s doable when the world’s hardest challenges meet Web3 grit.
However the actual shockwaves got here from the founders themselves: Vitalik Buterin and Tomasz Okay. Stańczak, Govt Director on the Ethereum Basis, who each appeared because the occasion’s on-line audio system, dropped two bombshells—400 TPS on Ethereum L1 this yr, and a close to future the place anybody can run a full node on their smartphone.
So what’s subsequent for the protocol? When does 400 TPS arrive, and what does “Ethereum in your telephone” truly imply for builders and customers? Right here’s what we realized at ETHKyiv 2025.
Subsequent-Gen UX: Nodes on a Telephone
Vitalik Buterin’s keynote at ETHKyiv 2025 lower straight to Ethereum’s core roadmap. The largest reveal:
“Fairly quickly you’ll have the ability to spin up a node in your smartphones and even smartwatches.”
In keeping with Buterin, as a substitute of counting on servers with terabytes of storage, quickly customers will have the ability to run a full Ethereum node “with out heavy-duty sources.” This primary-of-its-kind case shall be doable because of zero-knowledge Ethereum Digital Machines (zkEVMs) that the Ethereum Basis is presently implementing.
zkEVMs are making nodes drastically lighter, slicing storage by verifying transactions with out revealing and importing any details about them.
On Ethereum’s L2s, zkEVMs already lower transaction prices by as much as 90% and settle of their finality below three seconds. Buterin mentioned the following step is bringing these enhancements to the Ethereum mainnet, making blockchain interactions on it as quick and reasonably priced as conventional internet purposes.
400 TPS with 3-Slot Finality by 2026
At ETHKyiv 2025, Tomasz Okay. Stańczak, Co-Govt Director of the Ethereum Basis, spelled out precisely what’s subsequent for Ethereum’s spine: actual efficiency good points on the mainnet itself.
He revealed that by the tip of 2026, Ethereum will transfer to 3-Slot Finality (3SF), slashing common transaction affirmation time from quarter-hour all the way down to solely 36 seconds. For customers, it will convey the expertise of instantaneous conventional digital funds whereas holding all the advantages of decentralization.
Stańczak laid out the near-term milestones:
Ethereum L1 will hit 400 transactions per second (TPS) by the tip of 2025.
Block fuel limits will attain 100 million this yr, with a leap to 60 million per block in a month or two (as of publication date—ed.).
For context: scaling Ethereum L1 is important as a result of it anchors the complete ecosystem, offering the safety, settlement, and censorship resistance Layer 2s depend upon. With quicker mainnet throughput, customers get higher assurance their transactions are finalized on a decentralized, international community—not bottlenecked by L2 operators.
As Vitalik Buterin summed up:
“The purpose is to make Ethereum extra personal, extra censorship-resistant, and on the similar time, really easy that even folks removed from tech really feel secure utilizing it every single day.”
What’s Actually Fueling Ethereum’s Worth and Mass Adoption?
For me and all of the Ethereum followers, some massive questions have all the time remained: what truly underpins Ethereum’s worth, and what may set off mass adoption?
After I pressed each Vitalik Buterin and Tomasz Stańczak for solutions at ETHKyiv 2025, they every zeroed in on totally different however related drivers.
Tomasz pointed to 3 non-negotiables: privateness, knowledge safety, and transparency. In keeping with him, these are exactly what enterprise shoppers and common customers now count on from any blockchain platform.
“Ethereum is a world community, and elevated adoption instantly boosts the worth of the entire ecosystem,” he defined.
The extra Ethereum is used for real-world utility—by companies and by people—the extra demand, and finally, worth accrues.
Vitalik, in the meantime, framed the adoption query round monetary utility. His thesis: mass adoption comes when Ethereum turns into the rails for real-world property, significantly tokenized shares and bonds.
“They’re the gateway to mass adoption and the bridge between conventional finance and Web3,” he mentioned.
With heavyweights like BlackRock, Deutsche Financial institution, and Coinbase actively leveraging Ethereum for asset tokenization, we’re already seeing the strains blur between conventional finance’s $117 trillion market and Web3 infrastructure.
Briefly: Ethereum’s actual worth isn’t simply speculative, but it surely’s being constructed proper now on the intersection of safety, privateness, and sensible monetary purposes. That’s the place mass adoption begins to look inevitable.
Why ETHKyiv 2025 Issues for Ukraine and Past
ETHKyiv 2025 certainly stood out for its entry to international thought leaders. Regardless of all of the war-related dangers, builders right here heard first-hand insights from Ethereum’s most influential builders.
As Stańczak himself described it:
“Enterprise, DeFi, explorations, AI, analysis, day-to-day issues, working with folks—we now have to grasp the course and provides suggestions. A whole lot of it.”
His day by day routine—hours spent answering questions from builders—underscores how Ethereum’s energy lies in its folks, not simply its protocol.
Crucially, ETHKyiv 2025 was by no means simply one other tech occasion on the calendar. Held in opposition to the backdrop of an ongoing struggle, it grew to become residing proof of one thing greater: even within the darkest instances, Ukraine’s tech neighborhood chooses to construct, be taught, and join with the worldwide ecosystem.
All through the hackathon, the wartime context was unimaginable to disregard, but it wasn’t a shadow however a driving power. Performances by Moisei Bondarenko, the violinist-soldier whose music echoes by liberated Ukrainian cities, reminded everybody that innovation and humanity should go hand in hand. So did the tactical drugs session led by fight medic Artem Rudy, bringing sensible expertise and a way of shared resilience to the room.
That is what set ETHKyiv 2025 aside: it was a gathering of minds and hearts, a testomony to the persistence of neighborhood, curiosity, and shared values—even in wartime. The world watched not only for the tech, however for the spirit of resilience and solidarity that Ukraine’s builders dropped at the stage.
