This short educational series explains blockchain technology from a database and data management perspective, making it easier to understand how blockchain fits into modern computing systems.

The course begins with blockchain basics as a new paradigm for data management. It explains how blockchain differs from traditional databases by using decentralized structures instead of centralized storage, improving transparency and trust.

Next, it introduces cryptographic foundations, focusing on hashing. Hashing is a key concept that ensures immutability and security by converting data into fixed digital fingerprints that cannot be easily altered.

The series also covers cryptocurrency costs, explaining transaction fees and how users can optimize transactions within blockchain networks. This helps learners understand how blockchain systems balance performance and resource usage.

Another important topic is blockchain mechanics, including blocks, pointers, and proof-of-work. These concepts explain how blocks are linked together, how data is validated, and how mining secures the network through computational effort.

By the end of this series, learners will understand blockchain from a data engineering perspective, including how systems store,
