Abstract. This literature review examines the integration of ABCD (Artificial Intelligence, Blockchain, Cloud Computing, and Data Analytics) technologies in the Philippines, including adoption, worldwide developments, as well as particular applications. Despite the significant potential for ABCD technologies, the integration in healthcare, agriculture, financial, and educational sectors to increase efficiency, security, and ability to make decisions, challenges that are experienced include infrastructure constraints, skill gaps, and regulatory requirements. It manifests the enormous potential of ABCD if applied to engineering models such as Industry 4.0 and digital innovation in health care, e-commerce, and supply chains, predictive maintenance, transparent transactions, and automation. Early adopters can already be discerned in the Philippines, such as AI applications in agriculture and mental health, blockchain for secure records, cloud applications in education, and data analytics in health care- but still, lack of infrastructure and inability to find the people with proper skills slow the movement. Sectors like health and manufacturing, which have high growth potential, these technologies can become competitive engines for the Philippines. Recommendations on digital infrastructure, data privacy, public-private partnerships, and investment in workforce development would facilitate an enabling environment for supporting the culture of ABCD technologies.

Keywords: ABCD technologies; Artificial Intelligence; Digital transformation; Digital infrastructure; Innovation.
