Monero (XMR): The Privacy-Focused Cryptocurrency Mineable on CPUs

Monero (XMR) is a cryptocurrency focused on transaction privacy, launched in April 2014 as a fork of Bytecoin. Unlike Bitcoin, where all transactions are publicly visible on the blockchain, Monero makes sender, receiver, and transaction amount private by default. ## Privacy Technology **Ring signatures:** Each transaction is signed by a group of possible signers, making it computationally infeasible to determine which member actually authorized the transaction. The real sender is hidden among decoy inputs. **Stealth addresses:** Each transaction generates a one-time address for the recipient. Even if someone knows your public Monero address, they cannot determine which transactions on the blockchain were sent to you. **RingCT (Ring Confidential Transactions):** The transaction amount is cryptographically hidden. Observers can verify that inputs equal outputs (no coins created from nothing) without seeing the actual values. ## CPU Mining via RandomX Monero's RandomX mining algorithm, adopted in November 2019, is specifically designed for CPU efficiency. It uses random code execution, memory-hard operations, and instruction set features that CPUs handle natively but GPUs and ASICs cannot efficiently replicate. This design choice is deliberate: Monero's community values mining decentralization. If mining requires expensive specialized hardware (ASICs), it concentrates in large operations. CPU-mineable algorithms allow anyone with a standard computer — or even an old smartphone — to participate.

It is controversially listed as a tool for money laundering by some regulators, while privacy advocates argue that financial privacy is a fundamental right. Several exchanges have delisted Monero due to regulatory pressure, while others continue to support it.
