The following is a guest post and opinion of Rostyslav Bortman, Founder of Ethereum Ukraine.<\/em><\/p>\n

Even in wartime Kyiv, innovation doesn\u2019t pause. At ETHKyiv 2025<\/a>, more than 100 hackers proved it\u2014shipping privacy-first dApps, competing for grants, and showing what\u2019s possible when the world\u2019s toughest challenges meet Web3 grit.<\/p>\n

But the real shockwaves came from the founders themselves: Vitalik Buterin and Tomasz K. Sta\u0144czak, Executive Director at the Ethereum Foundation, who both appeared as the event's online speakers, dropped two bombshells\u2014400 TPS on Ethereum L1 this year, and a near future where anyone can run a full node on their smartphone.<\/p>\n

So what\u2019s next for the protocol? When does 400 TPS arrive, and what does \u201cEthereum on your phone\u201d actually mean for developers and users? Here\u2019s what we learned at ETHKyiv 2025.<\/p>\n

Next-Gen UX: Nodes on a Phone<\/h2>\n

Vitalik Buterin\u2019s keynote at ETHKyiv 2025 cut straight to Ethereum\u2019s core roadmap. The biggest reveal:<\/p>\n

\u201cPretty soon you\u2019ll be able to spin up a node on your smartphones and even smartwatches.\u201d<\/p><\/blockquote>\n

\"\"<\/p>\n

According to Buterin, instead of relying on servers with terabytes of storage, soon users will be able to run a full Ethereum node \u201cwithout heavy-duty resources.\u201d This first-of-its-kind case will be possible thanks to zero-knowledge Ethereum Virtual Machines (zkEVMs) that the Ethereum Foundation is currently implementing.<\/a><\/p>\n

zkEVMs<\/a> are making nodes drastically lighter, cutting storage through verifying transactions without revealing and importing any information about them.<\/p>\n

On Ethereum\u2019s L2s, zkEVMs already cut transaction costs by up to 90% and settle in their finality<\/a> under three seconds. Buterin said the next step is bringing these improvements to the Ethereum mainnet, making blockchain interactions on it as fast and affordable as traditional web applications.<\/p>\n

400 TPS with 3-Slot Finality by 2026<\/h2>\n

At ETHKyiv 2025, Tomasz K. Sta\u0144czak, Co-Executive Director of the Ethereum Foundation, spelled out exactly what\u2019s next for Ethereum\u2019s backbone: real performance gains on the mainnet itself.<\/p>\n

\"\"<\/p>\n

He revealed that by the end of 2026, Ethereum will move to 3-Slot Finality (3SF)<\/a>, slashing average transaction confirmation time from 15 minutes down to only 36 seconds. For users, this will bring the experience of instant traditional digital payments while keeping all the benefits of decentralization.<\/p>\n

Sta\u0144czak laid out the near-term milestones:<\/p>\n

Ethereum L1 will hit 400 transactions per second (TPS) by the end of 2025.<\/p>\n

Block gas limits will reach 100 million this year, with a jump to 60 million per block in a month or two (as of publication date\u2014ed.).<\/p>\n

For context: scaling Ethereum L1 is essential because it anchors the entire ecosystem, providing the security, settlement, and censorship resistance Layer 2s depend on. With faster mainnet throughput, users get greater assurance their transactions are finalized on a decentralized, global network\u2014not bottlenecked by L2 operators.<\/p>\n

As Vitalik Buterin summed up:<\/p>\n

\u201cThe goal is to make Ethereum more private, more censorship-resistant, and at the same time, so easy that even people far from tech feel safe using it every day.\u201d<\/p><\/blockquote>\n

What\u2019s Really Fueling Ethereum\u2019s Value and Mass Adoption?<\/h2>\n

For me and all the Ethereum followers, some big questions have always remained: what actually underpins Ethereum\u2019s value, and what could trigger mass adoption?<\/p>\n

When I pressed both Vitalik Buterin and Tomasz Sta\u0144czak for answers at ETHKyiv 2025, they each zeroed in on different but connected drivers.<\/p>\n

Tomasz pointed to three non-negotiables: privacy, data protection, and transparency. According to him, these are precisely what enterprise clients and regular users now expect from any blockchain platform.<\/p>\n

\u201cEthereum is a global network, and increased adoption directly boosts the value of the whole ecosystem,\u201d he explained.<\/p><\/blockquote>\n

The more Ethereum is used for real-world utility\u2014by businesses and by individuals\u2014the more demand, and ultimately, value accrues.<\/p>\n

Vitalik, meanwhile, framed the adoption question around financial utility. His thesis: mass adoption comes when Ethereum becomes the rails for real-world assets, particularly tokenized stocks and bonds.<\/p>\n

\u201cThey\u2019re the gateway to mass adoption and the bridge between traditional finance and Web3,\u201d he said.<\/p><\/blockquote>\n

With heavyweights like BlackRock, Deutsche Bank, and Coinbase actively leveraging Ethereum for asset tokenization<\/a>, we\u2019re already seeing the lines blur between traditional finance\u2019s $117 trillion market and Web3 infrastructure.<\/p>\n

In short: Ethereum\u2019s real value isn\u2019t just speculative, but it\u2019s being built right now at the intersection of security, privacy, and practical financial applications. That\u2019s where mass adoption starts to look inevitable.<\/p>\n

Why ETHKyiv 2025 Matters for Ukraine and Beyond<\/h2>\n

ETHKyiv 2025 indeed stood out<\/a> for its access to global thought leaders. Despite all the war-related risks, developers here heard first-hand insights from Ethereum\u2019s most influential builders.<\/p>\n

As Sta\u0144czak himself described it:<\/p>\n

\u201cEnterprise, DeFi, explorations, AI, research, day-to-day problems, working with people\u2014we have to understand the direction and give feedback. A lot of it.\u201d<\/p><\/blockquote>\n

His daily routine\u2014hours spent answering questions from developers\u2014underscores how Ethereum\u2019s power lies in its people, not just its protocol.<\/p>\n

Crucially, ETHKyiv 2025 was never just another tech event on the calendar. Held against the backdrop of an ongoing war, it became living proof of something bigger: even in the darkest times, Ukraine\u2019s tech community chooses to build, learn, and connect with the global ecosystem.<\/p>\n

\"\"<\/p>\n

Throughout the hackathon, the wartime context was impossible to ignore, yet it wasn\u2019t a shadow but a driving force. Performances by Moisei Bondarenko, the violinist-soldier whose music echoes through liberated Ukrainian cities, reminded everyone that innovation and humanity must go hand in hand. So did the tactical medicine session led by combat medic Artem Rudy, bringing practical skills and a sense of shared resilience to the room.<\/p>\n\n\n\n
\"\"<\/td>\n\"\"<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n

This is what set ETHKyiv 2025 apart: it was a gathering of minds and hearts, a testament to the persistence of community, curiosity, and shared values\u2014even in wartime. The world watched not just for the tech, but for the spirit of resilience and solidarity that Ukraine\u2019s builders brought to the stage.<\/p>\n","protected":false},"excerpt":{"rendered":"
