LFDT Labs Introduces CLPR - An Architectural Deep Dive into CLPR (Cross-Ledger Protocol)

Join us for an in-depth technical session introducing CLPR (Cross-Ledger Protocol), a newly approved open-source project hosted under the LF Decentralized Trust Labs.
Traditional cross-chain bridges often introduce security vulnerabilities, liquidity locking, and third-party trust assumptions. CLPR takes a fundamental shift: enabling direct, asynchronous ledger-to-ledger communication using cryptographic state proofs.

In this Meetup, we will explore:
Architectural Overview (20–30 min)
The problem with traditional bridges.
Core trust model.
Breakdown of the protocol layers.
How to adapt CLPR for arbitrary EVM, non-EVM, public, and enterprise ledger types.

Implementation Deep Dive (45–60 min)
Hiero Native Implementation
Besu Reference Implementation

Live Software Demo and Q&A (30 min)
Live Demonstration: Watching CLPR execute cross-ledger state proof verification in real time.

Q&A and Community Discussion and get involved in the LFDT Lab.

Aircraft parts and components move across airlines, manufacturers, suppliers, and maintenance organizations throughout their service lives. Keeping their maintenance and ownership records accurate and
consistent across these organizations is a continuing challenge, especially when each organization uses different enterprise systems.

In this session, Abhinag Vangala, a doctoral candidate at the University of the Cumberlands, will share an overview of his qualitative research on the use of Hyperledger Fabric for part and component traceability in
multi-organizational environments. The session will cover:

• The traceability challenge in aerospace maintenance, repair, and overhaul (MRO)
• What prior research has found, and where gaps remain
• Why Hyperledger Fabric was selected for this study
• The study’s three focus areas: system performance, enterprise system integration, and operational suitability

This session may interest Fabric developers, architects, and practitioners who have worked on networks involving multiple organizations.

Abhinag will also share how U.S. based professionals with experience in Hyperledger Fabric or enterprise permissioned blockchain systems can voluntarily take part in the study.
