Monero now accounts for 68% of dark web transactions, effectively displacing Bitcoin as the dominant currency on darknet markets. The privacy-focused cryptocurrency enforces ring signatures, stealth addresses, and hidden amounts on every transaction by default with no opt-out mechanism. This mandatory privacy architecture has driven adoption across illicit marketplaces where financial anonymity is paramount. Unlike Bitcoin's transparent ledger, Monero's protocol-level obfuscation ensures transaction details remain concealed regardless of user configuration.
