Fabric-X is a digital asset-specific implementation of Hyperledger Fabric. Join us for a series on meetups that go into detail about what Fabric-X is and how you can use it.

Fabric-X introduces a new programming model that redefines how business processes are developed on the blockchain. In this session, we’ll take a deep dive into the endorsement phase of Fabric-X, highlighting how it differs from the traditional Hyperledger Fabric model and what these changes mean for developers.

Through hands-on examples, we’ll demonstrate how the new model streamlines development and unlocks exciting possibilities for designing decentralized applications. We’ll also explore how to build applications tailored for tokenization use cases, enabling seamless on-chain asset representation and transfer.

To close the session, we’ll walk through practical deployment strategies using Ansible and Kubernetes, equipping you with the tools and confidence to bring your Fabric-X solutions into production.

Join us for a virtual meetup about Minokawa, the newest project hosted by LF Decentralized Trust. Minokawa joins the LFDT project ecosystem as an established codebase and with an existing user base. It was designed under the Compact brand with a clear set of goals: to make zero-knowledge smart contract development accessible, secure, and practical for real-world applications. Compact’s features and capabilities are now at the core of Minokawa. They include:

* Privacy by default
* Strong static typing
* Zero-Knowledge proof integration
* Separation of public and private state
* Developer accessibility

At its core, Minokawa addresses the structural limitations that have historically constrained the development of private, trustworthy smart contracts. On most blockchains, both contract state and logic are fully transparent, which makes them rather unsuitable for applications that involve sensitive information, such as credentials, personal identity, private preferences, or proprietary business logic.

Join us for this event to learn more about Minokawa and how to get involved in the project.

Besu, un proyecto de LF Decentralized Trust, es un cliente Ethereum de código abierto desarrollado bajo la licencia Apache 2.0 e implementado en Java. En este taller, aprenderás los conceptos básicos de las características de Besu y cómo operar y gestionar una red privada. A través de cuatro ejercicios prácticos, adquirirás experiencia práctica en la implementación, actualización, uso y supervisión de una red privada Besu.

El objetivo principal de este taller es proporcionar una comprensión integral de los aspectos teóricos y prácticos de Besu. Está diseñado para personas familiarizadas con la tecnología blockchain y el protocolo Ethereum. Si está buscando un punto de partida sólido para convertirse en un profesional certificado por Besu, este taller gratuito debería estar en su agenda.

Para participar en este taller, debe tener lo siguiente:

• 1. Un sistema operativo Linux para ejecutar scripts bash.
• 2. Software instalado: Metamask, Docker y Docker Compose.
• 3. El repositorio de código abierto del taller, que se puede descargar desde: https://gitlab.com/iobuilders-public/iob-besu-workshop.

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.
