LFDT Plovdiv

Fablo is a developer-friendly tool for quickly spinning up Hyperledger Fabric networks, best for local development and CI pipelines. It makes experimenting with different network configurations simple and declarative. Thanks to contributions from this year’s internship program, Fablo now includes exciting new features such as Chaincode-as-a-Service (CCaaS), Java chaincode hot reload (dev mode), and visualizing network topologies with Mermaid. Join us to see these features in action and learn how Fablo can streamline your Fabric development workflow.

Trust Over IP (ToIP) is a project hosted by LF Decentralized Trust that is working on providing a robust, common standard and complete architecture for Internet-scale digital trust. Leaders from the project will present about the work they are doing creating a draft specification of Running AI Agent Protocols over TSP (Trust Spanning Protocol). They are also working on documentation of canonical use cases of AI agents and how they relate to people in trust relationships and user experiences with various personas as well as planning a new task force to work on a trust framework for AI agents.

In this workshop, participants will gain a comprehensive understanding of the Hyperledger Cacti project—its current state, opportunities for contribution, and the end-to-end solutions it enables, with a special focus on the Secure Asset Transfer Protocol (SATP), soon to be an IETF standard. We will discuss how developers can contribute and extend the project by creating new plugins and connectors for unsupported distributed ledger technologies (DLTs). We will also showcase, use, and enhance existing end-to-end solutions already available within Hyperledger Cacti with SATP-based solutions as example use cases.

Key Topics Covered

• Introduction to Interoperability & Hyperledger Cacti: Brief overview of interoperability concepts, Cacti’s purpose, functionality, and modular architecture. We will refer the audience to previous workshops that delve into these topics.
• Integrated Multi-Modal Architecture: What has been achieved, ongoing work, and future directions.
• Building a Plugin From Scratch: Step-by-step walkthrough on creating a new connector for unsupported ledgers.
• Secure Asset Transfer Protocol (SATP): Introduction to IETF’s SATP, its design, operating model, and role in trust-minimized cross-network transfers.
• Demonstration of Asset Transfer Implementations in Cacti: Practical demonstrations will showcase asset transfers using Hyperledger Cacti end-to-end solutions. Participants will observe the solutions available in Hyperledger Cacti in action and gain hands-on experience in executing cross-network asset transfers.

Target Audience

The workshop is meant for developers, blockchain enthusiasts, and enterprise stakeholders who want to enhance their knowledge of DLT interoperability and standardized asset transfer protocols. While prior experience with blockchain fundamentals and some familiarity with Hyperledger Cacti can be helpful, it is not a strict requirement.
