Like Bitcoin and other traditional cryptocurrencies, the Electroneum blockchain uses a Proof-of-Work consensus algorithm where miners validate transactions in blocks and are compensated for their machine's work with $ETN tokens.
Electroneum aims to solve problems of many cryptos with a globally-accessible mobile app that works simultaneously as a wallet, payment platform and miner. In theory, anybody can download the mobile app and use it to mine $ETN, make and receive payments, and even track the currency's fiat value.
Through its website (which is also accessible via mobile), the company also offers an offline wallet generator and a relatively simple “import from offline wallet” feature to make cold storage user-friendly.
Electroneum is based on the Monero (XMR) codebase, so its stock features are essentially the same as Monero.
