About Proton (XPR)
Coinmarketcap XPR link: https://coinmarketcap.com/currencies/proton/
Proton (XPR) is a new public blockchain and smart contract platform designed for both consumer applications and peer-peer payments. It is built around a secure identity and financial settlements layer that allows users to directly link real identity and fiat accounts, pull funds and buy crypto, and use that crypto seamlessly in apps.
Proton provides a secure, verified identity account that is integrated with a financial settlement layer that allows users to directly link this identity with fiat accounts, pull funds and buy crypto, and use that crypto seamlessly in apps, all without sending any of the user’s private, sensitive information.
Proton removes the concept of sharing private keys directly with merchants, instead of creating a permission-less layer that exists on top of traditional card networks and banks. The user maintains the private key in confidence while permitting institutions who wish to authenticate the user to check with trusted institutions via public keys. The verification from the trusted institution will confirm the user’s identity without revealing the user’s associated private key.
