Monero stands out for several reasons. A primary goal of the project is to reach the highest possible degree of decentralization, ensuring that users do not have to place trust in other network participants.
The currency achieves privacy via specific mechanisms. Unlike Bitcoin, where every coin has a serial number allowing usage tracking, XMR is fully fungible. By default, information regarding senders, receivers, and transfer amounts is hidden. Proponents of Monero claim this provides an advantage over competing privacy coins like Zcash, which they describe as “selectively transparent.”
This obfuscation relies on ring signatures. The system selects previous transaction outputs from the blockchain to serve as decoys, preventing outside observers from identifying the actual signer. For instance, if Ian sends 200 XMR to Susan, the sum might be divided into random portions to increase complexity.
To prevent transactions from being linked, the network generates unique stealth addresses for each transfer, which are utilized only once.
These distinct characteristics have resulted in XMR being used more frequently than Bitcoin for illegal activities, particularly on darknet markets. Consequently, governments globally, with the U.S. being a notable example, have offered hundreds of thousands of dollars to individuals capable of breaking Monero’s encryption.
