Adaptive learning platforms personalize instruction by continuously modeling each learner’s knowledge, skills, and pace. Meanwhile, the integrity of academic records and micro-credentials increasingly depends on trustable, portable verification mechanisms across institutions and labor markets. This manuscript proposes and critically examines a reference architecture that unifies AI-powered adaptivity with on-chain credential verification based on decentralized identifiers (DIDs) and the W3C Verifiable Credentials (VC) data model. The design integrates real-time learner modeling (e.g., Bayesian/Deep Knowledge Tracing), reinforcement-learning sequencing, and learning analytics pipelines (xAPI/Caliper) to generate mastery-aligned learning pathways. When mastery thresholds are met, the system issues verifiable micro-credentials whose cryptographic proofs (hashes, revocation registries) are anchored to a permissioned or public blockchain, enabling instant, privacy-respecting verification without exposing sensitive learner data
