What is blockchain useful for

Blockchain technology is a decentralized digital ledger that records transactions in a secure and transparent manner. It was initially developed for the cryptocurrency Bitcoin, but its applications go far beyond finance. In this article, we will explore what blockchain is useful for and how it can revolutionize various industries.

What is Blockchain?

Blockchain is a distributed database that contains a continuously growing list of records called blocks. Each block contains a timestamp and a cryptographic hash of the previous block, creating an immutable chain of information. This decentralized architecture makes it resistant to tampering and fraud, making it ideal for securely storing and sharing data.
