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.

• Alejandro Dovale, Head of R&D at ioBuilders
• Marcos Serradilla, Product Engineer at iobuilders
• Guillermo Varela, DevOps Engineer at ioBuilders

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.

Join us for an exploratory session into DeDi — the decentralized trust infrastructure redefining how public data and registries are shared, verified, and consumed in the digital age.

What to expect
We’ll dig into:
1. Introduction to DeDi (Speaker: Amar Tumballi)
* The story behind DeDi: origin, mission, and positioning
* Real-life deployment use cases
* How to evaluate new opportunities for applying DeDi in your organization
2. Architecture of DeDi (Speaker: Mudit Sarda)
* The internal design and deployment modes of DeDi
* How scale, performance, and security are handled
* Areas open to contribution, improvement, and extension
We’ll wrap with a Q&A and open discussion: how DeDi could be leveraged in domains you care about (govtech, fintech, identity, compliance, etc.).
Resources
* DeDi’s site: Decentralized Directory for public registries (https://www.dedi.global/)
* GitHub / technical spec: Finternet / DeDi (https://github.com/LF-Decentralized-Trust-labs/DeDi)
* DeDi publish interface: publish.dedi.global (https://publish.dedi.global/)
Why Attend
* Understand a next-generation **Digital Public Infrastructure (DPI)** building block
* Learn how cryptographic trust, revocation propagation, cross-registry recognition, and verifiability are being solved end-to-end via DeDi ([dedi.global][1])
* Gain insight into how your organization can plug into or extend the DeDi ecosystem
* Network with peers, architects, and early adopters in the trust & infrastructure space
Who Should Join
* Software architects, system engineers, infrastructure leads
* Product leads / innovation teams in governments, NGOs, fintech, identity technology
* Researchers and technologists interested in trust, verifiable systems, decentralized infrastructure
* Anyone curious about the foundations of public data infrastructure
