Because each equation is unique, once it is solved, the network knows that the transaction must be authentic. Proof of work and proof of stake are two ways in which cryptocurrency miners can prove their ownership of new crypto assets. The crypto part refers to the fact that transactions are secured by cryptography -a form of coding -which is extremely difficult to hack or break. This uses a huge amount of computing power. This is where people use computers to solve difficult mathematical puzzles. New bitcoins are created by what’s known as cryptocurrency “mining”. So if cryptocurrencies aren’t issued by banks or governments, where do they come from? How is cryptocurrency created? This is a piece of code which authorises outgoing transactions on the blockchain network so you can spend the funds. When you buy digital currency, you own a private key. All the computers that store and update copies of the blockchain technology have to “agree” on the correct version of the public ledger. It is nearly impossible to counterfeit cryptocurrency. While transactions are recorded on this public ledger, the details of the people trading cryptocurrencies are not – you remain anonymous, which can be part of their appeal. Not controlled by any central bank or government.Transactions can’t be faked, or overwritten. This ledger allows data to be shared globally, in order to verify transactions and prevent fraudulent double spending of cryptocurrencies.Ĭryptocurrency works by writing blocks and recording transactions to the ledger. (A blockchain is a decentralised database that is maintained across a computer network and can be viewed by anyone at any time it can’t be hidden.) Instead it operates on a peer-to-peer network, with transactions being recorded on a public ledger using blockchain technology. How does cryptocurrency work?Ĭryptocurrency is decentralised, meaning it’s not run by a central authority such as governments, central banks or financial institutions. As codes are used to protect information this is supposed to bring greater security.Īll bitcoin transactions are recorded in a database known as a blockchain, which prevents people from spending the same coin twice. Records of cryptocurrency ownership are held on a computerised database secured by strong cryptography. In order to “unlock” the cryptocurrency you need the equation to crack the code – it’s a sort of virtual key. Creating new cryptocurrency is known as mining. The most recognisable cryptocurrency is bitcoin, which has exploded in popularity.īitcoin is created with an encrypted code (basically like a string of numbers and letters). While cryptocurrencies can be used to buy items in some stores, it is more commonly traded as digital assets as a way to profit from investment returns. It is an internet-based medium of exchange. It is a digital asset, so you can’t hold it or touch it as you would with pound coins or notes. When you own crypto you will hold it in a digital wallet – rather than an imaginary ether What is cryptocurrency in simple terms?Ĭryptocurrency is virtual money that is able to circulate without any input from banks. What are the dangers of cryptocurrency?.
