Arrivals & Registration: Scaling Trust in the Age of AI — Builders Sessions
Session details
Join us to learn how to build neuro-symbolic AI using the open-source OriginTrail Decentralized Knowledge Graph (DKG) and Knowledge Assets for trusted, rule-based reasoning. Leverage the immensely powerful combination of blockchains, knowledge graphs, and LLMs to build the future of AI—trusted AI.

Understanding the Power of Collective Neuro-Symbolic AI: Introduction to OriginTrail DKG
Speaker
Branimir Rakić — Founder & CTO @OriginTrail
Session details
Learn about the core concepts and technologies of the OriginTrail Decentralized Knowledge Graph (DKG) to build your own trusted AI solutions, powered by neuro-symbolic AI. Collective neuro-symbolic AI combines structured, connected, and verifiable information from symbolic AI (DKG) with the creativity of neural AI technologies (LLMs). This creates a robust, decentralized AI infrastructure through which both humans and machines can share knowledge, reason together, and preserve context across time.

Get started with the OriginTrail DKG: Build with the NEW DKG Edge Node
Speaker
Nikita Abrashkin — Lead Infrastructure Engineer @Trace Labs — OriginTrail Core Developers
Session details
Learn how to install and start building with the NEW DKG Edge Node - a framework for building neuro-symbolic AI agents based on the OriginTrail DKG. In this workshop, you will build a basic DKG-based neuro-symbolic agent, accessible via a user interface (chatbot), Model Context Protocol (MCP), and a classic API. You will be able to customize it to your will by building plugins and extensions.

Build Your First DKG Agent
Speaker
Zvonimir Šćulac — Software Engineer @Trace Labs — OriginTrail Core Developers
Session details
Learn all about the neuro-symbolic AI agent colocated within the DKG Edge Node. The DKG Agent enables DKG nodes not only to publish and query semantic knowledge but also to perform knowledge graph reasoning, summarization, and data transformation tasks directly on locally or remotely stored knowledge. Learn about the DKG Agent's modular plugin system centered on the Model Context Protocol (MCP) and how to create your own custom plugin to extend the agent's functionality.

Build Your Neuro-Symbolic AI Agent with Reusable Data Products and the DKG
Speakers
Charles Ivie — Senior Graph Architect @AWS Amazon Neptune
Ben Clinch — Partner @Ortecha
Branimir Rakić — Founder & CTO @OriginTrailSession details
Data products are reusable, curated, and trustworthy data assets with a specific business purpose, designed for easy consumption and reuse. They can unlock massive ROI and reduce ownership costs, but current implementations often suffer from complexity, high cost, and poor interoperability. Learn about DPROD, a semantic standard for building secure, reusable Data Products designed for trusted neuro-symbolic AI agents. The workshop will provide a hands-on experience using: Graph.Build ontology; Amazon Neptune; OriginTrail DKG.

Ema Lovšin — Head of Growth @Trace Labs — OriginTrail Core DevelopersSession details
Meet the winners of the OriginTrail DKG Global Hackathon. The hackers were competing in 4 bold challenges to build a collective digital immune system for the AI era:
- 📚 Grokipedia vs. Wikipedia: Truth AlignmentComparing topic pages across Grokipedia and Wikipedia, quantifying similarity, finding divergences, and detecting hallucinations/bias.
- 📝 Decentralized Community Notes: Misinformation & DeepfakesExtending the Umanitek Guardian Social Graph datasets with fact-checks as triples, linking notes to content (text/images/video).
- 🗣️ Social Graph ReputationComputing reputation from the provided Social Graph (e.g., PageRank + token/stake signals; Sybil-resistant weighting).
- 🃏 Wild CardAny combination of the above or out-of-the-box ideas, leveraging the DKG Edge Node, and all 3 layers of the system: Agent-Knowledge-Trust Layer.
