Cryptocurrency is a digital or virtual currency that is secured by cryptography, making it difficult to counterfeit or double-spend. The concept of cryptocurrency has been around for several years, but it wasn’t until the launch of Bitcoin in 2009 that it started to gain popularity. Since then, numerous other cryptocurrencies have emerged, each with its own unique features and characteristics.
History of Cryptocurrency
The idea of cryptocurrency was first introduced in the 1980s by computer scientist David Chaum, who founded a company called DigiCash. However, it wasn’t until the launch of Bitcoin that the concept of cryptocurrency started to gain mainstream attention. Bitcoin was created by an individual or group of individuals using the pseudonym Satoshi Nakamoto, and it was designed to be a decentralized currency that was not controlled by any government or institution.
How Cryptocurrency Works
Cryptocurrency works by using a technology called blockchain, which is a public ledger that records all transactions made with the currency. The blockchain is maintained by a network of computers around the world, and it is updated in real-time as new transactions are made. When a transaction is made, it is broadcast to the network and verified by special computers called nodes, which use complex algorithms to validate the transaction and add it to the blockchain.
