About us
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.

Trusted AI Agents by Design: From Trust Ecosystems to Authority Continuity
Rapid innovation in agentic AI is opening up real potential. But agents don't just forward intent, they create it. When an agent makes the decisions that matter, trust can't be assumed, it has to be designed in. And once agents cross organizational boundaries, decentralized trust infrastructure has a critical role to play.
This session brings together two complementary pieces tackling that fundamental challenge, followed by a panel. This is the timeframe to get things right. Join us.
5:00 PM Opening & Framing – Shane Deconinck
5:10 PM Running AI Agent Protocols over Trust Spanning Protocol – Wenjing Chu
How TMCP and TA2A bring secure, interoperable communication to AI agent ecosystems, built on the Trust Spanning Protocol.
5:35 PM Authority Is Continuous – Nicola Gallo
Introducing PIC (Provenance Identity Continuity Protocol) and its Proof of Continuity as an emerging security primitive for distributed transactions and agent chains.
6:00 PM Closing Panel: Connecting the Layers – Moderated by Shane Deconinck
We'll discuss how the proposed solutions fit together, which pieces are still missing, how they align with existing standards and ongoing work in the space, and what's needed to move from specification to adoption, with plenty of room for interaction.

AIA: An Open-Source Semantic Framework for Universally Interpretable Impact Data
·OnlineOnline294 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
·OnlineOnline112 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.

Nightstream: Provable Coroutines for Containers and Contracts
·OnlineOnline85 attendees from 166 groupsNightstream is a proof system capable of proving infinite streams of computation, modeled as coroutines via a post-quantum lattice-based zkVM. It supports multiple opcodes sets including riscv, but has a focus on Wasm components to prove contract and container execution. Join this meetup to learn more about the Nightstream lab and how to get involved.

ZK Learning Group: FRI (Fast Reed-Solomon IOP of Proximity)
·OnlineOnline57 attendees from 140 groupsA learning group for zero knowledge and SNARK application development.
A 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
Github repo for the lab:
https://github.com/LF-Decentralized-Trust-labs/zk-learning-groupIn this session, we will continue discussing elements of STARK and introduce concepts of FRI: Fast Reed-Solomon IOP of Proximity.
