Blockchain Week Bulgaria 2026 is locked in for September 23 to 25 at Sofia Tech Park, with organizers confirming a lineup that includes the Digital Euro Association, Sygnum Bank, and Crédit Agricole. The event splits into two tracks — ETHSofia, focused on blockchain infrastructure and research, and F3 – Future Finance Forum, which tackles the transformation of financial systems and capital markets. It’s the fourth edition of the conference, and organizers are betting on Sofia’s growing pull as a European digital hub.
Two conferences, one venue
ETHSofia leans technical: distributed systems, AI infrastructure, cybersecurity, and blockchain research. F3, meanwhile, drills into tokenization, CBDCs, and regulatory shifts. The overlap is intentional — speakers from Chainlink Labs, ChainSecurity, and the Aave Chain Initiative will appear alongside representatives from the Financial Supervision Commission and the University of National and World Economy (UNWE). Partners include UEB3, Pashov Audit Group, UNRAMP, BITOMAT, and BRAIN++, Bulgaria’s AI Factory linked to the EuroHPC network.
The lineup
Confirmed participants cut across banking, academia, and DeFi. Sygnum Bank — a Swiss regulated crypto bank — and Crédit Agricole signal institutional interest. The Digital Euro Association will likely push the CBDC discussion. Aave Chain Initiative and ChainSecurity bring the DeFi security angle. Organizers framed the gathering as a sign that Europe is entering a new phase where AI, financial infrastructure, and distributed tech are increasingly interconnected.
Why Sofia
Bulgaria’s capital has been quietly building a tech scene. The event is supported by the Financial Supervision Commission — the country’s markets regulator — and UNWE, suggesting the government is keen to position Sofia as a node in Europe’s digital infrastructure. BRAIN++, the Bulgarian AI Factory, ties the conference to EuroHPC supercomputing projects. The mix of public institutions and private blockchain firms is the selling point.
The big picture
Blockchain Week Bulgaria lands at a moment when Europe is wrestling with MiCA implementation and stablecoin rules. Events like this — not just a trade show but a cross-sector meetup — are where the actual policy and product conversations happen. Organizers said Europe is entering a new phase of digital transformation, and Sofia wants to be in the room.
