Monero is a privacy-preserving cryptocurrency based on the CryptoNote protocol. Its key components are anonymity, security, and fungibility. Recipients and senders of Monero use unique, one-time only, public keys for every transaction. These are called Stealth Addresses and mitigate the risks of wallet data mining, a non-trivial concern of Bitcoin users. Another feature, Ring Signatures, is also used in every transaction and is made by fusing a transaction’s actual signer with a group of random signers pulled from past transactions in the blockchain. This masks the true identities of the sender and receiver.
