International Conference on Blockchain Technology (ICBT)

Barcelona, Spain closes out ICBT's May run on May 27-28, 2027, following Paris, Berlin and Sydney earlier in the month. Indexed by Conference Index and organized under the World Academy of Science, Engineering and Technology, the two-day conference follows the federation's paper-first format: submit work, get reviewed, present to a mixed academic and practitioner room.

The timing works in attendees' favour. Late May puts you in Barcelona before the worst heat and the deepest summer crowds, and the slot pairs neatly with a few extra holiday days if your employer counts that sort of thing.

The call for papers runs from foundations to fringe. Distributed ledger technology, trust models and platform governance form the spine. Around it sit blockchain and finance, tokenization, emergent payment platforms, financial inclusion, cryptocurrency regulation, and the thorny meeting point of law and protocol design.

Applied tracks cover applications of smart contracts, enterprise blockchain deployments, decentralized identity and wallet solutions, DAOs, NFT innovation and proof-of-work mining economics. The wider net catches AI and robotics, cloud computing, economic paradigms and game theory, IoT services, cyber-physical systems, software-defined networks and data engineering. Token, Ethereum and Bitcoin research are explicitly tagged.

Final submissions are due April 23, 2027, a month before the conference, tight enough that accepted papers should arrive essentially finished. The notification date on the listing, September 16, 2026, is months earlier than either milestone, which only makes sense under continuous review; verify directly with WASET if acceptance timing matters to your funding or visa planning.

Registration and paper handling run through waset.org, with a program page reserved for the Barcelona edition. No venue appears on the index listing yet, so leave bookings flexible.

Since the New York edition shares these exact dates, some delegates face a genuine choice. Pick Barcelona for the European research crowd, shorter flights from EMEA and a city built for lingering conversations; pick New York for American connections. Both draw from the same call, so the intellectual content will rhyme.

Whichever you choose, do the boring checks early. Confirm the venue once announced, price flights accordingly, and remember that Barcelona's established conference districts mean competing events can tighten hotel availability quickly in late May.

With final submissions due April 23, 2027, the practical move is to draft the abstract now against the call's own vocabulary. The topics give you hooks: game-theoretic economics, software-defined networks, cyber-physical systems and data engineering all appear beside the blockchain core, which is an invitation for systems people who usually skip crypto events.

Choosing between Barcelona and its New York twin comes down to whom you want in the corridor conversations. Barcelona pulls European academia and a strong fintech services industry within a short flight; New York pulls American finance and policy. The papers may rhyme but the questions from the floor will not, and those questions are where the real value hides. Whichever you pick, submit early enough to leave room for the camera-ready sprint, keep the registration receipt tidy for reimbursement, and remember that late May in Barcelona means hotels sell out around any major event week, not just this one. Book refundable rates and thank yourself later.
