Inside Eth Sofia 2025: The Balkan Blend Of Builders, Academics, And Innovators

What Happened

The second edition of ETH Sofia positioned the Balkans as one of Europe’s most dynamic intersections of academic research and blockchain innovation.

As Sofia once again turned into a meeting point for builders, thinkers, and innovators, ETH Sofia 2025 confirmed why the Balkans are becoming one of Europe’s most promising Web3 regions. From founders, academics, and regulators to sponsors and developers, the event reflected a shared ambition: to educate, connect, and drive the next wave of blockchain progress.

Having hosted both the first and second editions of ETH Sofia, I’ve had the chance to watch the event rise from a bold local experiment into a regional benchmark for collaboration between the blockchain industry, academia, and public institutions. What once felt like an emerging scene now feels like a structured movement with knowledge exchange at its core.Over two days, ETH Sofia welcomed more than 550 participants from over 20 countries, featuring 80 speakers, 26 main stage sessions, and 12 side events across the city.

Market Context

“The vision has always been twofold: to bring the Bulgarian crypto community together and to educate newcomers about permissionless blockchain technology and themes like DeFi, privacy, Web3 security, trading automation, and regulation.”

Why It Matters

The program extended beyond panels with workshops, open-stage talks, and academic presentations that connected students, researchers, and founders in meaningful discussions about the future of blockchain.

“By the community, for the community”

For founder Vlad Dramaliev, ETH Sofia has always been more than a conference. He said:

Dramaliev emphasized the importance of showcasing Balkan innovation:

“Conferences like ETH Sofia are reflections of the ecosystem and should serve as amplifiers of the success of represented projects.”

He also noted the growing regional collaboration:

“ETH Belgrade was an inspiration. We even discussed synchronizing Balkan crypto events so they occur one after another. That’s harder in practice, but the idea remains strong.”

The human side of moderation

Moderator Alexandra from Thrilld Labs shared how she prepared to guide conversations on stage.

“I’m not a natural public speaker. As a kid, I was very shy. But once I started bartending and later became a founder, it changed.”

Her approach is built on preparation:

“I research every speaker, practice names, and pay attention to what’s covered on stage so I can make smooth transitions or add a small joke.”

She credited the event team for creating an exceptional experience.

“The front-end of the stage is what people see, but the real full-stack experience is built by the team working for months behind the scenes. ETH Sofia’s team was epic.”

Her favorite sessions included Nicolas Bacca’s talk from Ledger and ZKNox, and Khashim Arziyev’s insights from Binance. “Both were smart, engaging, and accessible, which isn’t always an easy balance.”

Uniting a fragmented region

Tina Petkova, Event Manager of ETH Sofia, described ETH Sofia’s mission as bridging gaps within the Balkan Web3 ecosystem. She said:

“Our goal was to unite developers, entrepreneurs, and researchers under one roof and make ETH Sofia feel like their event: by the community, for the community.”

“The biggest challenge was the fragmentation of the community. The region is full of talent, but it’s scattered. Balancing newcomers with global protocol veterans turned into one of the event’s greatest strengths.”

She added that building continuity is key:
