LFDT Berlin

CBWeb3, an LFDT Lab, is being developed as a Digital Public Good (DPG), leveraging open-source protocols, interoperability standards, and blockchain-neutral infrastructure to address key challenges in financial inclusion, whole-sale cross-border payments, and tokenization.

During this session, we will present:
•⁠ ⁠The vision of CBWeb3.
•⁠ ⁠Use cases in domestic settlement (DvP) and cross-border payments (PvP).
•⁠ ⁠The governance guiding its development.
•⁠ ⁠Opportunities for the open-source and global blockchain community to contribute to the creation of a interoperable, and collaborative ecosystem for Latin America and the Caribbean.

If you're interested in getting more involved with the CBWeb3 lab, you're welcome to join the weekly calls on Thursday at 8:00 AM Pacific that will be starting on October 23, 2025.

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 the other Fabric-X meetups

• November 19: Fabric-X-Orderer Overview: A Scalable BFT Ordering Service for Fabric-X
• December 9: Fabric-X-Committer: A Microservices-Based Committer Architecture for Ultra-High Throughput

Speakers

• Marcus Brandenburger, Researcher at IBM Research
• Angelo de Caro, Senior Technical Staff Member at IBM Research
• Ilie Circiumaru, Solution Architect at IBM Research
• Alessandro Sorniotti, Principal Research Scientist at IBM

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.
