LFDT & CLPR

Hallo in die Runde,
unser drittes Meetup aus der Reihe „Decentralized Trust Ruhrgebiet“ hat einen finalen Termin. Entstanden aus dem WEB3-Event „ALL IN ONE – WEB3 TRIFFT WIRTSCHAFT“, hat das DUH-IT-Projektteam (Fraunhofer IML und TU Dortmund) mit Open Elements die Veranstaltung für die lokale Vernetzung ins Leben gerufen. Nach zwei Meetups mit sehr positiver Resonanz geht es nun in die dritte Runde.
Am 02.12.2026 geht’s weiter, und wir laden Euch ganz herzlich erneut in den Projektspeicher ein! Diesmal dreht sich alles um offene Zusammenarbeit an DLT: Wir schauen uns an, wie die Linux Foundation Decentralized Trust (LFDT) Projekte herstellerneutral entwickelt, und lernen mit CLPR eines ihrer jüngsten Projekte kennen. Im Anschluss bleibt wieder ausreichend Zeit bei dem ein oder anderen Getränk sowie leckeren Snacks und Pizza für Austausch und Vernetzung.

LFDT – What is it and why is it important for DLT
Jessica Gonzalez & Sophie Bulloch

Decentralized technologies only succeed when enterprises trust them, and that trust rarely comes from code alone. It comes from neutral governance, transparent decision-making, reliable security practices and a community that outlives any single company. This is the role LF Decentralized Trust plays for its projects.

In this talk, we look at LFDT from two angles. One of us works for the foundation and sees the big picture: how projects find their home at LFDT, how they mature from incubation to graduation, what the Technical Advisory Council does, and which services projects can use, from security and compliance support to events and marketing. The other is a maintainer who works on an LFDT project every day and shows what this means in practice: how open governance changes the way decisions get made, what it takes to turn a single-vendor codebase into a multi-stakeholder project, and where the foundation actually makes a difference, and where it doesn't.

We take a tour through the LFDT landscape, from enterprise ledgers and digital identity to cryptographic tooling, and show how these projects complement each other. A special focus is the community side: mentorship programs that bring new contributors into the ecosystem, working groups where cross-project topics are tackled, and the many ways individuals and companies can get involved.

Attendees will leave with a clear picture of what LFDT offers, how to engage with it, and why vendor-neutral governance is a competitive advantage rather than overhead.

CLPR – Cross-Ledger Communication without Bridges
Hendrik Ebbers

Distributed ledgers still mostly operate as isolated islands. Moving tokens, data or messages between them usually means relying on bridges or federated relayer networks, and these have turned out to be critical weak spots: they concentrate trust in operators or validator sets, lock up liquidity and have been the target of exploits costing billions.
CLPR (pronounced “clipper”), the Cross-Ledger Protocol, takes a different approach. Instead of trusting an intermediary, ledgers verify each other’s state directly using cryptographic state proofs. Trust is established between the ledgers themselves, without an additional trust layer, without custodians and without a single point of failure, while the security assumptions of each participating network remain intact.
Just as important as the technology is where it lives. CLPR is a vendor-neutral specification hosted at LF Decentralized Trust and developed under the stewardship of the Linux Foundation. Originally created by Hashgraph and contributed by Hedera, it is no longer owned by any single company. Instead, it is shaped in the open by everyone who wants to connect their ledger, so that cross-ledger communication can become a shared standard rather than one vendor’s product.
This talk introduces the problem CLPR solves, its trust model and the architecture behind asynchronous ledger-to-ledger communication, and places it among other interoperability approaches. It then looks at the project itself: how the specification is developed as an LFDT Lab, how its open governance is being set up, how the weekly open meeting works and how developers, companies and researchers can get involved.
