BCCA 2026: A Convergence of Advanced Technologies Shaping the Digital Ecosystem The convergence of Artificial Intelligence (AI) and blockchain, and the future of the digital ecosystem it will transform, has emerged as a significant area of interest for both the global tech industry and researchers. The International Conference on Blockchain Computing and Applications (BCCA 2026), which will bring together these trends for discussion, is scheduled to take place from July 27 to 29, 2026. BCCA is the largest niche conference in the cryptocurrency and fintech sectors, providing a platform for international academic researchers, practitioners, and policymakers studying crypto finance and related fields to debate current issues in cryptocurrency and digital finance, propose new ideas, and discuss future research directions. Beyond mere technical presentations, this conference will cover advanced technological topics such as blockchain, Large Language Models (LLMs), Web3 infrastructure, digital twins, and quantum-safe blockchain. These themes reflect the latest trends in technology convergence today, offering a crucial opportunity for all stakeholders seeking to understand and lead an intelligent and secure digital ecosystem. In particular, this event focuses on the convergence of emerging technologies, including AI, distributed systems, cybersecurity, and IoT-based applications. BCCA 2026 goes beyond simply listing and presenting technologies. The conference serves as a platform for interdisciplinary collaboration, simultaneously examining the possibilities and limitations of technology and determining its trajectory through dialogue among academia, industry, and policymakers. It actively encourages interdisciplinary conversations connecting theory, engineering, and practical deployment, fostering a community that explores the cutting edge of cryptocurrency research. Participants will have the opportunity to expand their professional networks and improve their research through high-quality feedback. For instance, sustainable computing technologies will be a focal point at this event, with intensive discussions on methods for efficient data processing while simultaneously reducing environmental impact. Sustainable computing encompasses concepts such as the development of energy-efficient blockchain consensus mechanisms, the operation of carbon-neutral data centers, and eco-friendly cryptocurrency mining methods, reflecting the global tech industry's efforts to address climate change while continuing digital innovation. In particular, quantum-safe blockchain technology has emerged as a crucial element capable of presenting a new paradigm for financial and national data security. Given that the advancement of quantum computing has the potential to neutralize existing encryption methods, the development of quantum-resistant blockchain technology is a core challenge for future digital security. In-depth discussions are expected at this conference on quantum-safe cryptographic algorithms, Post-Quantum Cryptography standards, and methodologies for integrating them into blockchain protocols. Large Language Models (LLMs) and decentralized AI are another key topic. The recent advancements in LLMs such as ChatGPT, GPT-4, and Claude have opened new horizons for AI technology, but simultaneously raise issues of data privacy, centralized AI power concentration, and AI bias. Decentralized AI, combined with blockchain technology, offers potential solutions to these problems. Decentralized AI networks can enhance privacy by decentralizing data and computing resources, and increase the transparency and accountability of AI models. At BCCA 2026, research on the technical implementation, governance models, and real-world application cases of decentralized AI will be shared. Web3 infrastructure is gaining attention as a foundational technology for the next generation of the internet. Web3 proposes a new internet paradigm based on the core principles of decentralization, user sovereignty, and token economics. Blockchain forms the backbone of Web3 infrastructure, enabling innovative structures such as smart contracts, decentralized applications (DApps), and Decentralized Autonomous Organizations (DAOs). At this conference, discussions will cover issues such as Web3 infrastructure scalability, interoperability, user experience improvement, and integration strategies with existing Web2 systems. The Meeting of AI and Blockchain: Key Issues for Academia and Industry Digital twin technology is also one of the important topics at BCCA 2026. A digital twin is a technology that creates a digital replica of a physical asset, process, or system, enabling real-time monitoring, simulation, and optimization. Digital twins combined with blockchain can enhance data integrity, traceability, and multi-party collaboration. For example, in supply chain management, smart cities, manufacturing, and healthcare, blockchain-based digital twins can significant
