In this short video, we explain what Blockchain is in simple words according to the Aga Khan Board (AKUEB) Computer Science syllabus. Blockchain is a technology where data is shared across many computers in a network instead of being stored in one central place. Because of this distributed system, no single person can easily change or delete the information, which makes blockchain secure, transparent, and reliable. This concept is important for students preparing for Computer Science exams and practical understanding.
