This chapter examines the evolution of microcredentials and digital badges, highlighting their impact on education and workforce development. Microcredentials complement traditional degrees by recognizing specific skills acquired through informal and self-directed learning. Introduced in 2012, the Open Badges specification standardized how these digital credentials are packaged, verified, and shared. The authors illustrate how digital badges, enhanced through sophisticated metadata, digital signatures, and decentralized verification methods, effectively address gaps left by traditional credentials. Special emphasis is placed on establishing trust, particularly critical in STEM fields, by ensuring transparent assessments, issuer credibility, and verifiable evidence. The chapter identifies current challenges and explores future opportunities, suggesting how emerging technologies might further personalize and secure digital credentialing.
