Cryptocurrencies are digital assets which are used as a digital store of value and medium of exchange.
Cryptocurrencies act as a decentralised, flexible, and programmatic form of capital within blockchain networks. They are embedded with encryption technology that prevents double-spending and allows individuals to verifiably prove their ownership of an asset. Cryptocurrencies can be used as digital currencies for peer-to-peer payments, as the medium to pay for data settlement in a block, as collateral in decentralised finance (DeFi) applications, and much more.
Another primary function of cryptocurrencies is to incentivise blockchain security participants to act according to network rules. This is critical in coordinating and deriving consensus about the state of the network. In exchange for proposing valid data attestations to the network, blockchains offer rewards in the form of cryptocurrencies. Dishonest data attestations that do not garner consensus from the network earn no rewards and can be subject to penalties. In this way, cryptocurrencies provide an incentive mechanism that allows blockchains to operate securely without any central points of control.
