What is Blockchain?
Blockchain is a digital ledger technology that allows for secure, decentralized, and transparent record-keeping of transactions or data. In simple terms, it is a continuously growing list of records, called blocks, that are linked and secured using cryptography. Each block contains a timestamp and a cryptographic hash of the previous block, forming a chain of blocks (hence the name “blockchain”).
Once a block is added to the chain, it cannot be altered or deleted without altering all subsequent blocks, which makes it highly secure and tamper-proof. Blockchain technology has gained significant attention and is being explored for various applications, such as in finance, healthcare, supply chain management, and more.
