Blockchain has matured beyond cryptocurrencies into infrastructure for DeFi, tokenized assets, DAOs, and digital governance. At the same time, agentic AI, meaning systems that can plan, decide, and act autonomously, is moving from assisting people to acting on their behalf. AI agents are beginning to trade, negotiate, manage assets, and coordinate with one another, increasingly on-chain. The two technologies are converging. Blockchain offers agents verifiable identity, programmable payments, and auditable records, while agents are reshaping how decentralized markets and communities operate. This convergence raises new questions about trust, accountability, security, privacy, and governance when machines act for people and organizations. This workshop brings together scholars to examine blockchain ecosystems and agentic AI through theory, empirical research, design science, and emerging applications.
