Buddhism is generally divided into 2 major philosophical schools, the older hinayana and the newer mahayana. These two schools differ in how one defines a Buddha and highly realized beings and how one understands the reality of self and phenomena. They have a different understanding of vicarious joy and equanimity, as well as differing understandings of the 10 perfections. For Mahayana Buddhists, everyone has equal potential to become a Buddha. Buddha-nature is not discussed by Hinayana Buddhists.
