At ETHKyiv 2025, despite the ongoing war, over 100 developers showcased cutting-edge privacy-focused decentralized apps (dApps) and competed for grants. The standout announcements came from Ethereum co-founder Vitalik Buterin and developer Tomasz K. Stańczak, who revealed major upgrades—including achieving 400 transactions per second (TPS) and enabling "Ethereum on your phone," signaling big strides in scalability and accessibility for the blockchain.

Editor’s Note: This isn’t just tech jargon—it’s a big deal for Ethereum users and developers. Faster transactions (400 TPS) and mobile compatibility could make Ethereum more practical for everyday use, while the event itself highlights how Ukraine’s tech community keeps pushing forward despite adversity. For crypto enthusiasts, these upgrades could mean smoother, cheaper, and more user-friendly blockchain experiences.
