Dec 1, 2025December 2025 highlights for KeychainMDIP/kc: Delivered high-impact features, enhanced security, and deployment flexibility across the project. Implemented automatic app reload on service/config changes to ensure latest configurations are applied and user experience remains seamless. Introduced a Bitcoin inscription mediator for the mainnet with supporting Docker configuration and environment variables. Modernized cryptography by replacing node-forge with Web Crypto API implementations. Added environment-variable-driven frontend deployment toggles for Keymaster and Gatekeeper, enabling flexible service orchestration. Implemented read-only mode for the mediator when the export loop is disabled to conserve resources. Major bug fixes included: restored clean state during reimport to ensure data integrity, and stabilized bitcoin-core mediator error handling to avoid failures on undefined errors. Overall impact: shorter deployment cycles, improved security posture, better resource management, and more scalable frontend deployment. This work demonstrates strong skills in configuration-driven deployment, cryptography modernization, and end-to-end feature delivery. Release note: Version bumped to reflect ongoing 1.4.x beta progression.
