⬛Let's understand what blockchain means 🟫

Blockchain is a type of modern technology that allows data to be stored securely and transparently, as data is stored in chains of blocks connected to each other. The data in each block is secured using encryption processes that make it difficult to change or tamper with the data. Blockchain is commonly used in digital currency technologies such as Bitcoin, but it can also be used in a wide range of other applications that require data to be stored securely and tamper-proof.
