What is Blockchain Technology?

At its most basic level, blockchain technology is a decentralized digital ledger that is used to record transactions. It was invented in 2008 by an anonymous person or group using the pseudonym Satoshi Nakamoto, as a way to create a decentralized digital currency called Bitcoin.

How Does Blockchain Work?

Blockchain technology works by creating a network of computers that collectively maintain a ledger of transactions. Each transaction is recorded in a block, which is then added to the chain of blocks (hence the name “blockchain”). Once a block is added to the chain, it cannot be altered or deleted, making the ledger immutable and highly secure.

What is Cryptocurrency?

How Does Cryptocurrency Work?

Each transaction is encrypted and added to the blockchain, creating a permanent record that cannot be altered or deleted. Transactions can be made anonymously, making cryptocurrency a popular choice for those who value privacy.
