What is blockchain?
Blockchain is an unchangeable, distributed ledger which is used to record transactions and monitor assets across a corporate network. It is a type of information storage that stops people from modifying, manipulating, or deceiving it.
A blockchain is open to the public since it exists on the network rather than within a single entity. To preserve virtual security, a blockchain is encrypted and employs public and private keys. The blockchain enables individuals to transfer money to other individuals without using a financial institution.
The most well-known application of blockchain is in cryptocurrency. Some examples of digital tokens are Bitcoin, Ethereum, and Solana. Crypto, like a digital version of cash, may be used to purchase everything from cars to houses. Unlike cash, cryptocurrency employs blockchain to serve as a public ledger as well as an advanced cryptographic security mechanism, ensuring that all online transactions are always recorded and protected.
The idea of blockchain came into reality in 2008 with Satoshi Nakamoto perhaps motivated by the financial systems crash in the same year. He developed a peer-to-peer electronic cash system known as Bitcoin. This is what became the foundation of distributed ledger systems (Blockchain).
