Jonas Ampferl
Developed core features for the THI-CSI/decentralized_iam_battery_data platform, focusing on decentralized identity and verifiable credentials for battery data management. Over three months, delivered a blockchain-based backend with persistent storage, RESTful APIs for blocks, DIDs, and verifiable credentials, and Docker-based environment bootstrapping to streamline onboarding and integration. Leveraged Go and Python to implement CLI tools, consensus mechanisms, and automated data generation, while enhancing security through cryptography and DID/VC workflows. Refactored service setup, improved error handling, and expanded documentation to support scalable testing and partner integration. The work emphasized reliability, data integrity, and maintainability across distributed systems and cloud environments.

Jun 1, 2025June 2025 monthly summary for THI-CSI/decentralized_iam_battery_data. This month delivered end-to-end bootstrap, data flow improvements, security features, and reliability enhancements that advance the platform's business value. Highlights include Docker-based environment bootstrap for blockchain and cloud integration with automatic Python venv initialization, reimplementation of Mock BMS with improved data flow and cloud UI data generation, OEM service for BMS with DID creation/registration and VC creation/signing with refactored service access, and cloud/blockchain integration stability fixes including a blockchain.json initialization guard. Additional progress includes tooling and maintenance enhancements (tools.py service monitor on steroids, countdown indicators for Mock BMS, random value generator for test data), battery data generation refactor with JSON schema cleanup, service setup refactor, dependency updates and VC handling fixes, and expanded documentation and multi-BMS testing support. These deliverables reduce onboarding time, improve data integrity, strengthen security posture with verifiable credentials, and enable scalable testing and maintenance.
