Monero is a privacy focused currency created in 2014. A participant on the Bitcointalk forum going by the username “Thankful_for_today” forked Bytecoin to create Monero, which was later maintained by the decentralized developer community. Monero is fungible, meaning that involvement in previous transactions does not affect the value of any one coin as all transaction history is completely unknowable. Monero uses senders’ unique ring signatures, confidential recipient addresses and Ring Confidential Transactions to enable privacy and prevent coins being spent more than once at a time.
