Blockchain Week Bulgaria 2026 hosts ETHSofia and F3

Blockchain Week Bulgaria 2026 will gather technology leaders, financial institutions, policymakers, researchers and infrastructure providers at Sofia Tech Park from Sept. 23 to 25. The programme combines two conferences, ETHSofia and F3 – Future Finance Forum, focused on blockchain, digital finance and AI infrastructure.

ETHSofia will target engineers, protocol architects, developers and researchers working on distributed computing and blockchain infrastructure. Sessions will cover privacy-preserving technologies, scalable network architectures and techniques for designing resilient systems for public blockchains and enterprise environments. Presentations will include research findings, engineering practices and reports from real-world deployments.

F3 will focus on institutional use of digital technologies in banking, payments, capital markets and public-sector infrastructure. Topics listed for the forum include tokenisation and digital assets, central bank digital currencies, settlement infrastructure, regulatory updates and the application of AI in financial systems. The programme is expected to attract banks, fintech executives, infrastructure providers, institutional investors and regulators from across Europe.

Organisers report partnerships with industry and infrastructure groups including UEB3, Pashov Audit Group, UNRAMP, BITOMAT and BRAIN++. Strategic collaborators include the University of National and World Economy and Bulgaria’s Financial Supervision Commission. BRAIN++, described as the Bulgarian AI Factory and a member of the EuroHPC network of AI factories, will provide on-demand access to AI models and secure, in-country data infrastructure aimed at the fintech sector.

Invited organisations and participants are expected to include representatives from the Digital Euro Association, Sygnum Bank, Crédit Agricole, Chainlink Labs, ChainSecurity and the Aave Chain Initiative, among other European institutional and infrastructure stakeholders. The event’s organisers wrote in a statement, “Europe is entering a new phase of digital transformation where AI, financial infrastructure, and distributed technologies are increasingly interconnected.” The statement added that the programme aims to bring technical experts, institutions and policymakers together to discuss systems that may shape the next decade.

Sofia Tech Park was selected as the venue to involve regional academic, public and private actors in discussions about finance and technology and to reflect Sofia’s expanding role in Europe’s digital infrastructure landscape. The conference schedule will include technical talks, policy panels and industry sessions geared toward both research communities and institutional decision-makers.

Additional speakers, partners and side events will be announced in the coming months. Media accreditation requests and partnership inquiries are being handled by the Blockchain Week Bulgaria team.
