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/

ZK Learning Group: STARK
·OnlineOnline261 attendees from 139 groupsA learning group for zero knowledge and SNARK application development.
During the year we will systematically explore different aspects of zero knowledge and SNARK programming in application development.
Coordination of the learning group is in the discord channel of Linux Foundation Decentralized Trust: https://discord.com/channels/905194001349627914/1329201532628898036

In this session, we will kick-off 2026 and introduce basic concepts of STARK (Scalable Transparent Argument of Knowledge).1 attendee from this group - Network event

Programming Chaincode in Rust for Hyperledger Fabric
·OnlineOnline133 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
·OnlineOnline224 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 accounting
Join us for an overview of how AIA can help your impact data become more interoperable, auditable, and reusable!1 attendee from this group
