1. Introduction to Blockchain

Blockchain technology has emerged as a revolutionary innovation in the realm of digital transactions. It is a decentralized, distributed ledger that records transactions across multiple computers so that the record cannot be altered retroactively without the alteration of all subsequent blocks and the consensus of the network. This makes blockchain a highly secure and transparent platform for various applications.

2. Understanding Cryptocurrencies

Cryptocurrencies are digital or virtual currencies that use cryptography to secure transactions, to control the creation of new units, and to verify the transfer of assets. Unlike traditional fiat currencies, cryptocurrencies are not controlled by any central authority and operate independently.

3. The Intersection of Blockchain and Cryptocurrencies

The intersection of blockchain and cryptocurrencies lies in the fact that blockchain is the underlying technology that powers most cryptocurrencies. It ensures the security, transparency, and immutability of transactions in the cryptocurrency ecosystem.
