Monero

Monero (XMR) is a privacy-focused cryptocurrency designed so that transactions are confidential by default. Launched on 18 April 2014 as a fork of Bytecoin, built on the CryptoNote protocol, Monero has become the most widely used privacy coin and one of the longest-running community-driven projects in crypto, with no company, pre-mine, or venture funding behind it.

How Monero works

Unlike Bitcoin, where every transaction is publicly traceable, Monero obscures transaction details at the protocol level. It combines several techniques: ring signatures mix a sender's output with others so the true source cannot be identified, stealth addresses generate one-time destination addresses so payments cannot be linked to a recipient, and Ring Confidential Transactions (RingCT) hide the amounts being transferred. Privacy is mandatory for all transactions, not optional — a key difference from Zcash.

Monero uses Proof of Work consensus with the RandomX algorithm, which is deliberately designed to be efficient on ordinary CPUs and resistant to specialized ASIC mining hardware. This keeps mining accessible to individuals and helps decentralize the network's security.

Supply and role in the ecosystem

Monero has no fixed maximum supply. After the initial emission of about 18.4 million XMR, the network moved to a "tail emission" of 0.6 XMR per block, a small perpetual issuance that funds miners indefinitely and keeps the network secure without relying solely on transaction fees. Roughly 18.8 million XMR are in circulation.

Monero occupies a distinct position in the crypto ecosystem as the leading fully private digital cash. It is valued by users who prioritize financial confidentiality and fungibility — the property that every coin is interchangeable because none carries a visible transaction history. Its privacy guarantees have also led some exchanges in certain jurisdictions to delist it, making availability more varied than for transparent cryptocurrencies.
