About us
Verteilte Systeme (Distributed Ledger Technology) verbreiten sich immer mehr in der Industrie und sind heute kein reines Instrument mehr für spekulative Kryptowährungen oder NFTs. Die TU Dortmund, das Fraunhofer IML, Open Elements und die Linux Foundation DT nehmen dies zum Anlass, über aktuelle Entwicklungen und Business Cases dieser neuen Technologien zu informieren.
Auch wenn Blockchains die Basis bilden, geht es bei Distributed Ledger Technology vielmehr um digitale Identitäten (Personalausweis der Zukunft), Real World Assets (Besitzzertifikate von Immobilien) und sicherem Datenaustausch zwischen Entitäten (Länder, Firmen, Individuen).
Zu unseren Veranstaltungen laden wir alle Interessierten aus Industrie, Politik und der öffentlichen Gesellschaft ein, um sich über diese Themen zu informieren und auszutauschen.
Dieses Meeting ist Bestandteil der LF Decentralized Trust (LFDT) Community. Mehr Info zu LFDT findet man unter http://lfdecentralizedtrust.org/
Die LFDT Meetup Guidelines findet man unter http://meetups.lfdecentralizedtrust.org
Die Meetup-Reihe wird zudem im Rahmen des EFRE-Forschungsprojektes DUH-IT unterstützt. Weitere Informationen finden Sie unter https://duh-it.de/

Programming Chaincode in Rust for Hyperledger Fabric
·OnlineOnline162 attendees from 140 groupsIntroducing the fabric-sdk-rust repo (https://github.com/LF-Decentralized-Trust-labs/fabric-sdk-rust) for writing chaincode for Hyperledger Fabric networks. Next to interacting with the network in Rust, the latest update also allows you to write chaincode in Rust, allowing writing full Rust based applications. This is a good session for anyone interested in developing with Hyperledger Fabric.

AIA: An Open-Source Semantic Framework for Universally Interpretable Impact Data
·OnlineOnline234 attendees from 166 groupsClimate and sustainability projects generate vast amounts of impact data — but too often, that data is hard to compare, integrate, or audit. Different projects use different terms, schemas, and structures — even when they are measuring the same underlying phenomena. This fragmentation creates friction for integrators and limits meaningful, global, cross-platform impact accounting.
On 17 February 2026 at 08:00 AM Pacific, the LFDT CA2-SIG Standards Working Group will present the Anthropogenic Impact Accounting (AIA) ontology suite, an open-source semantic framework designed to address this challenge. Developed over four years through rigorous bi-weekly working sessions and multiple redrafting cycles, the AIA suite provides a coherent and extensible foundation for expressing impact data in a universally interpretable way.
The first public release of AIA, published on 16 September 2025, comprises four modular, W3ID-registered ontologies:
- claimont (https://w3id.org/claimont): Semantics for claims, claimants, evidence, and attestations
- infocomm (https://w3id.org/infocomm): Communication primitives for structured information exchange
- impactont (https://w3id.org/impactont): Foundational concepts for modeling impact relationships
- aiao (https://w3id.org/aiao): An integrated framework for anthropogenic impact accountingJoin us for an overview of how AIA can help your impact data become more interoperable, auditable, and reusable!

Workshop: CREDEBL For Decentralized Identity and Verifiable Credentials
·OnlineOnline98 attendees from 166 groupsAs adoption of Decentralized Identity (DID) and Verifiable Credentials (VCs) accelerates across governments, education, enterprises, and regulated industries, developers and organizations need open, interoperable, and production-ready infrastructure to build trusted digital ecosystems.
This webinar introduces CREDEBL, an LF Decentralized Trust project, and walks participants through how to get started quickly, understand the architecture, and explore real-world use cases - all backed by open standards and community-driven development.
Whether you are a developer, architect, policy stakeholder, system integrator, or ecosystem partner, this session will help you move from concepts to implementation.
What We’ll Cover
- The Problem: Fragmented Digital Trust : Why identity, credentials, and verification remain siloed - and how this limits interoperability, privacy, and adoption.
- The Foundation: Verifiable Credentials & Decentralized Identity : A brief overview of DIDs, VCs, DIDComm, OID4VC, trust frameworks and where CREDEBL fits within the LFDT ecosystem.
- The Platform: CREDEBL Architecture : Core components, issuer–holder–verifier flows, APIs, and deployment models.
- Getting Started Fast: One-Click / Minimal-Config Setup : Live walkthrough of setting up CREDEBL and running end-to-end credential flows.
- Live Demo: Issuance & Verification in Action : Creating DIDs, issuing credentials, wallet interactions, and verification scenarios.
- Real-World Adoption & Ecosystem Use Cases : Education, digital identity, enterprise and public-sector use cases.
- Community, Governance & Roadmap : Open-source contribution model, roadmap, and how to get involved with the CREDEBL and LFDT community.
