Most Simplest Crypto Definition | What is Cryptocurrency and How does Crypto Works | Voice of Crypto
Cryptocurrencies are digital or virtual currencies underpinned by cryptographic systems. They enable secure online payments without the use of third-party intermediaries. “Crypto” refers to the various encryption algorithms and cryptographic techniques that safeguard these entries, such as elliptical curve encryption, public-private key pairs, and hashing functions.
Cryptocurrencies can be mined or purchased from cryptocurrency exchanges. Not all eCommerce sites allow purchases using cryptocurrencies. In fact, cryptocurrencies, even popular ones like Bitcoin, are hardly used for retail transactions. However, the skyrocketing value of cryptocurrencies has made them popular as trading instruments. To a limited extent, they are also used for cross-border transfers.
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.
The 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 chains, 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.
