What is a blockchain in cryptocurrency?

blockchain appears to be sophisticated as it can be, its core notion is pretty simple. A database, or blockchain, is a sort of digital ledger. To comprehend the concept of blockchain, it is necessary to first understand what a database is. A database is a collection of data saved on a computer system in an electronic format.

Distributed ledger technology (DLT) is a decentralized database that various network participants administer. Blockchain is a type of DLT where transactions are recorded using a hash, which is an immutable cryptographic signature. This means that if a single block in a chain is modified, it will be immediately clear that the chain has been tampered with. Private and centralized blockchains, on the other hand, exist in which all of the computers that make up the network are owned and operated by a single company.

Popular cryptocurrencies such as Bitcoin and Ethereum are built on blockchain technology. Blockchains like Bitcoin and Ethereum are constantly growing as new blocks are added to the chain, increasing the security of the ledger dramatically.
