European Chapter: SwissLedger - The Swiss Institutional Blockchain
·OnlineOnline50 attendees from 165 groupsJoin us for an LF Decentralized Trust European Chapter meetup featuring a 30-minute talk titled SwissLedger: The Swiss Institutional Blockchain, presented by Lorenzo Barisone from the City of Lugano.
SwissLedger is a Swiss institutional blockchain designed for regulated use cases across banking, industry and public administration. It evolved from Lugano’s city-level blockchain initiatives into a national-scale infrastructure, with governance, security and compliance built in by design.In this session, Lorenzo will outline SwissLedger’s public-permissioned Proof of Authority (PoA) model, consortium governance and compliance-ready architecture. He will also present real-world use cases already in production, including Verify Lugano for document authenticity and notarisation, as well as financial sector applications such as tokenisation and programmable finance.
After the talk, the meetup will follow the standard LF Decentralized Trust European Chapter agenda, including short updates from members and ongoing initiatives, followed by open discussion.
This session is relevant for professionals interested in institutional adoption of blockchain and regulated distributed ledger technology.Relevant links:

AIA: An Open-Source Semantic Framework for Universally Interpretable Impact Data
·OnlineOnline246 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
·OnlineOnline99 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.
