Monero is a cryptocurrency launched in 2014 with privacy as its core design goal, in contrast to Bitcoin and Ethereum, where transaction amounts and wallet addresses are publicly visible to anyone who looks at the blockchain. Monero uses cryptographic techniques to obscure the sender, receiver, and amount involved in each transaction.
This is achieved through several combined technologies, including methods that make it difficult to link a transaction to a specific sender or receiver, and techniques that hide the transaction amount from public view while still allowing the network to verify that no coins were created out of thin air.
Because of this strong privacy focus, Monero has faced additional scrutiny from regulators and has been delisted from some exchanges in certain jurisdictions, while remaining available on others. Its core community generally views financial privacy as a fundamental right rather than a feature meant to enable illicit activity.
