What is Blockchain technology?

Blockchain technology is a decentralized, digital ledger system that is used to record
and verify transactions. It consists of a continuously growing list of records, called
blocks, which are linked and secured using cryptography. Each block contains a
cryptographic hash of the previous block, a timestamp, and transaction data. Once a
block is added to the chain, it cannot be altered without invalidating all subsequent
blocks. This makes the blockchain a tamper-proof and immutable ledger of all
Blockchain technology was originally developed to support the digital currency
Bitcoin, but it has since been adopted by a variety of industries for its ability to
securely store and transfer information without the need for intermediaries.
Applications of blockchain technology include cryptocurrency, smart contracts,

supply chain management, and digital identity verification, among others.
