What Is Cryptocurrency?

A cryptocurrency is a digital or virtual currency that is secured by cryptography, which makes it nearly impossible to counterfeit or double-spend. Many cryptocurrencies are decentralized networks based on blockchain technology—a distributed ledger enforced by a disparate network of computers. A defining feature of cryptocurrencies is that they are generally not issued by any central authority, rendering them theoretically immune to government interference or manipulation.Blockchain
Central to the appeal and functionality of Bitcoin and other cryptocurrencies is blockchain technology. As its name indicates, blockchain is essentially a set of connected blocks or an online ledger. Each block contains a set of transactions that have been independently verified by each member of the network. Every new block generated must be verified by each node before being confirmed, making it almost impossible to forge transaction histories.1The contents of the online ledger must be agreed upon by the entire network of an individual node, or computer maintaining a copy of the ledger.

Experts say that blockchain technology can serve multiple industries, such as supply chain, and processes such as online voting and crowdfunding. Financial institutions such as JPMorgan Chase & Co. (JPM) are testing the use of blockchain technology to lower transaction costs by streamlining payment processing.2
