What we’re about
LFDT Meetup groups have an informal relationship with LF Decentralized Trust and make up a key part of the LFDT ecosystem. Participation in a LFDT Meetup group is open to anyone--employees of a LFDT member company, LFDT contributors and developers, and people just passionate about distributed trust technology.

•OnlineDecentralized Directory (DeDi)—Infrastructure, Use Cases & Architecture
Online121 attendees from 166 groupsJoin 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

•OnlineTrust Over IP 5th Anniversary Virtual Symposium-Advancing Digital Trust Together
Online59 attendees from 188 groupsJoin us on November 19 and 20 for the Trust Over IP Virtual Symposium, celebrating five years of pioneering open standards for digital trust infrastructure!
Hear from leaders as Day 1 features presentations on the dual nature of the ToIP stack, the Trust Spanning Protocol, trust registries, practical zero-knowledge proofs, and real-world implementations in British Columbia and Bhutan.
Day 2 offers interactive workshops on trust in AI agents, ToIP trust task protocol design, verifiable relationship credentials, eKYC challenges, and decentralized trust networks.

•OnlineFabric-X-Orderer Overview: A Scalable BFT Ordering Service for Fabric-X
Online223 attendees from 166 groupsFabric-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-Orderer is the new ordering service designed for Fabric-X, built on a scalable Byzantine Fault Tolerant (BFT) consensus protocol named Arma. Arma introduces key architectural innovations to support high transaction throughput, including the separation of consensus from transaction dissemination, and the use of sharding and pipelining to enhance parallelism in transaction processing. These techniques enable Arma to achieve over 100,000 transactions per second (TPS) for small transactions, meeting the performance targets of Fabric-X.
In this meetup, we will provide an overview of the Fabric-X-Orderer architecture, delve into the underlying protocols, and share performance evaluation results that highlight its scalability and efficiency.
Join us for the other Fabric-X meetups
- October 21: Fabric-X – Programming Model and Application Development Deep Dive
- December 9: Fabric-X-Committer: A Microservices-Based Committer Architecture for Ultra-High Throughput
Speaker
- Yoav Tock, Research staff member at IBM Research
