In this example, the learners Alice, Bruno and Carol access typical LMS like Coursera, Udemy, Edx, MIT xPRO, and OpenCourseWare to take specific courses.

Each LMS uses its own LRS to read/store learners' activities, adopting the xAPI standard as usual. With PoLiL, the LMS at startup prompts the learner to grant access to their private activity records stored in the blockchain. When allowed, the LMS will also store records of learners' current activities during courses.

Cardano (with a mixed on-chain and off-chain approach) will contain the personal and immutable learning records of every single user. Alice, Bruno and Carol can access their personal journey data anytime, everywhere and show the certifications of their lifelong learning journey.
