Monero (XMR) is a cryptocurrency built on blockchain technology that focuses primarily on privacy and fungibility. Created in April 2014, Monero differentiates itself from other digital currencies by obfuscating its public ledger, so external parties are unable to see source, amount or destination of a transaction. This is core to the fungibility that Monero (XMR) offers, as no single Monero can be tainted or devalued by previous transactions (as they are obscured).
