Cryptocurrency Privacy Unveiled: Comparative Evaluation of Leading Anonymous Coins

7/30/20242 min read

In the initial stages of the Bitcoin network, cryptocurrency was widely perceived as fully anonymous. However, as time progressed, experts uncovered methods to trace and identify Bitcoin transactions. In response, creators of new cryptocurrencies aimed to incorporate genuinely anonymous transaction capabilities into their coins.

At present, three prominent anonymous cryptocurrencies are in circulation: Dash, ZCash, and Monero. Let’s delve into a comparison of the privacy mechanisms adopted by these currencies.

Dash employs the CoinJoin technique to bolster privacy. It offers two transaction categories: regular transactions and those with heightened privacy through the optional “PrivateSend” feature. The PrivateSend function divides a transaction into multiple segments and blends them together. It’s noteworthy that Bitcoin also has similar services termed mixers, but Dash seamlessly integrates this function into its protocol, in contrast to Bitcoin mixers which are often privately developed and may carry fraud risks. While the CoinJoin method obscures fund flows and curtails direct transaction tracking, it doesn’t guarantee complete anonymity.

ZCash was the pioneering cryptocurrency to not only enhance transaction confidentiality but also effectively anonymize transactions. In ZCash, payments are recorded on a public blockchain, while concealing the sender, recipient, and transaction amount. ZCash employs the zk-SNARK protocol based on the Zero-Knowledge principle of proof. The Zero-Knowledge protocol avoids full information recording on the blockchain, rendering extraction from the network extremely challenging. Similarly to Dash, ZCash offers both regular and private transactions, albeit with differing implementations. ZCash comprises two types of addresses: z-addresses, safeguarded by zero-disclosure proof protocols, and t-addresses, openly available similar to Bitcoin. Transactions can transpire between z-addresses and t-addresses. However, this mingling of addresses poses a primary hurdle to ZCash’s anonymity, as transitioning between “unsecured” and “secure” addresses reduces transaction anonymity by 69.1%. Transactions involving distinct address types are even less anonymous, and by observing user behavior, one might potentially glean insights into z-addresses.

Monero adopts the CryptoNote protocol, ensuring that when a transaction is sent, the sender, recipient, and amount sent remain unobservable. Monero employs distinctive technologies such as Ring Signatures, Stealth Addresses, and coin interchangeability (fungibility). Exclusive private keys authenticate fund transfers, making Monero the most anonymous cryptocurrency presently available. To date, no instances of hacking or decrypting Monero transactions have been reported. However, certain research groups have identified flaws in the mixing algorithm, suggesting the potential decryption of select Monero transactions.

Unlike Dash and ZCash, Monero exclusively employs private, non-anonymous transactions.

In conclusion, Monero presently stands as the most technologically sophisticated cryptocurrency concerning privacy, offering the highest degree of anonymity. It remains impervious to known vulnerabilities that could compromise anonymity. It’s crucial to acknowledge that other facets of these currencies were not considered in this comparison, such as regulatory factors.
