The next is a visitor put up 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 exhibiting what’s doable when the world’s hardest challenges meet Web3 grit.
However the true shockwaves got here from the founders themselves: Vitalik Buterin and Tomasz Ok. Stańczak, Government 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 12 months, 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.”
Based on 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 will probably be doable due to zero-knowledge Ethereum Digital Machines (zkEVMs) that the Ethereum Basis is at present implementing.
zkEVMs are making nodes drastically lighter, chopping storage by way of 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 underneath three seconds. Buterin stated the following step is bringing these enhancements to the Ethereum mainnet, making blockchain interactions on it as quick and reasonably priced as conventional net purposes.
400 TPS with 3-Slot Finality by 2026
At ETHKyiv 2025, Tomasz Ok. Stańczak, Co-Government Director of the Ethereum Basis, spelled out precisely what’s subsequent for Ethereum’s spine: actual efficiency beneficial properties 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 right down to solely 36 seconds. For customers, it will convey the expertise of instantaneous conventional digital funds whereas preserving 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 12 months, with a bounce 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 all the ecosystem, offering the safety, settlement, and censorship resistance Layer 2s rely 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 objective is to make Ethereum extra personal, extra censorship-resistant, and on the identical time, really easy that even individuals removed from tech really feel protected utilizing it daily.”
What’s Actually Fueling Ethereum’s Worth and Mass Adoption?
For me and all of the Ethereum followers, some huge questions have all the time remained: what truly underpins Ethereum’s worth, and what might 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 linked drivers.
Tomasz pointed to 3 non-negotiables: privateness, information safety, and transparency. Based on him, these are exactly what enterprise shoppers and common customers now anticipate from any blockchain platform.
“Ethereum is a worldwide 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 in the end, 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 belongings, notably tokenized shares and bonds.
“They’re the gateway to mass adoption and the bridge between conventional finance and Web3,” he stated.
With heavyweights like BlackRock, Deutsche Financial institution, and Coinbase actively leveraging Ethereum for asset tokenization, we’re already seeing the traces 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 individuals—we have now to know the path and provides suggestions. Quite a lot of it.”
His day by day routine—hours spent answering questions from builders—underscores how Ethereum’s energy lies in its individuals, not simply its protocol.
Crucially, ETHKyiv 2025 was by no means simply one other tech occasion on the calendar. Held towards the backdrop of an ongoing battle, it grew to become residing proof of one thing larger: even within the darkest occasions, Ukraine’s tech group chooses to construct, study, and join with the worldwide ecosystem.
All through the hackathon, the wartime context was inconceivable to disregard, but it wasn’t a shadow however a driving drive. Performances by Moisei Bondarenko, the violinist-soldier whose music echoes by way of liberated Ukrainian cities, reminded everybody that innovation and humanity should go hand in hand. So did the tactical medication 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 group, 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.
