CosmoTrace: Permissioned Industrial Ledger & Digital Twin
A permissioned Cosmos SDK ledger for connecting supply chain state with MES and digital twin telemetry.
Overview & Research Motivation
CosmoTrace is an industrial cyber-physical prototyping project exploring how shopfloor Manufacturing Execution Systems (MES), OPC-UA/Modbus industrial protocols, and digital twin state can synchronize with an auditable permissioned ledger.
Built with the Cosmos SDK and CometBFT consensus engine under a Proof-of-Authority/Access-Control-List model, the system facilitates batched cryptographic anchoring of machine telemetry, decentralized identifiers (DIDs) for manufacturing equipment, and Inter-Blockchain Communication (IBC) for cross-enterprise parts traceability.
The Core Systems Problem
- Manufacturing shopfloors operate closed SCADA/MES silos that cannot be audited by tier-1 suppliers or compliance auditors without granting unrestricted internal network access.
My Specific Technical Contributions
- Developed custom Cosmos SDK modules for industrial asset registration and batch telemetry state hashing.
- Configured OPC-UA and Modbus TCP telemetry bridges connecting physical PLC controllers to the local validator node.
- Implemented Merkle proof generation for auditable product batch quality certifications.
System Architecture & Verification Pipeline
Industrial Protocol Gateway
