Monero
Monero is a leading privacy-focused cryptocurrency that uses ring signatures, stealth addresses, and RingCT to make transactions untraceable and unlinkable by default. Launched in 2014 as a fork of Bytecoin, Monero employs a proof-of-work consensus mechanism with the RandomX algorithm designed to resist ASIC mining. It features dynamic block sizes, tail emission for perpetual miner incentives, and is widely regarded as the most battle-tested privacy coin in the cryptocurrency space.
