What is Blockchain and why is it used?

The question is about blockchain

Answer

Blockchain is a decentralized digital ledger that records transactions across multiple computers in a way that ensures security and transparency. It is used primarily because it enhances trust and reduces the risk of fraud by making data immutable and easily verifiable. Blockchain technology is commonly applied in industries like finance, supply chain, and healthcare to improve data integrity and streamline processes. By eliminating intermediaries, Blockchain can also reduce costs and increase efficiency in various applications.
