This document proposes a decentralized learning model using blockchain and social networking services. It discusses implementing a "learning economy" approach where learning experiences are tailored to individual needs, and incentives motivate learning. Knowledge is organized into "capsules" containing information fragments on a particular topic. Learners can submit information, purchase capsules, and be rewarded through a "proof of work" system recorded on the blockchain. The goals are to expand learning opportunities and sustainably develop learner abilities through a market-based system that reflects social needs.
