Privacy Coins Explained

Privacy Coins Overview

Privacy Coins are a special type of cryptocurrency designed to increase transaction privacy and obfuscate on-chain data, within the limits of technical feasibility. Their distinctive feature lies in mechanisms aimed at minimising the amount of publicly available information about transfers. With most non-privacy cryptocurrencies, analysing a transaction allows one to obtain information about addresses, amounts, and transaction history, which can often be linked to users through additional data. 

Also, privacy coins limit the amount of publicly visible on-chain transaction data within the blockchain. This means they cannot hide information outside the cryptosystem, so even when using privacy coins, users may still be identified through external services (for example, via KYC procedures).

Key examples of popular privacy coins

Among the most well-known privacy-focused cryptocurrencies are Monero (XMR) and Zcash (ZEC). Dash is sometimes mentioned in this context due to its optional CoinJoin-based features, but it is generally not classified as a true privacy coin. Each privacy coin has its own characteristics, and the choice of a particular one depends on the specific use case.

For example:

• XMR offers the highest level of anonymity;

• DASH focuses on fast and low-cost transactions; its optional privacy features provide limited obfuscation, not full anonymity.;

• ZEC allows selective disclosure or concealment of transaction history, which can be beneficial — and in some cases necessary.

How Privacy Coins Work

Privacy coins use different privacy mechanisms depending on the protocol, such as stealth addresses, ring signatures, confidential transactions, or zero-knowledge proofs. Thus, the user has a general permanent address, but the system never interacts with this address directly.

In practice, when someone sends you privacy coin funds, you simply receive the assets as a single transaction. However, for the system (and for any external observer), depending on the protocol, the transaction may appear as a set of decoy inputs (e.g. Monero) or may be fully shielded using zero-knowledge proofs (e.g. Zcash shielded pools).

Benefits of Privacy Coins

The main benefits of privacy coins are the high level of privacy, which allows users to hide transaction details and amounts. This is particularly useful when a user does not wish to disclose their information to third parties unnecessarily.

In addition, because transactions involving privacy coins cannot be easily tracked by outsiders, transaction privacy can reduce exposure of on-chain financial data, but it does not protect users from malware, phishing, compromised wallets or social engineering attacks.

Use cases in global finance and e-commerce

Privacy coins in crypto can be used for international transactions (including e-commerce) when increased anonymity is required and when the parties wish to avoid unnecessary attention from other users. For example, a business may conduct a transaction with international partners while wanting to keep this information as private as possible.

In addition, this type of cryptocurrency may reduce on-chain traceability, but cannot prevent funds from being blocked or restricted at the exchange, wallet provider or off-ramp level.

Regulatory challenges and legal considerations

Due to their ability to significantly conceal transaction information, privacy crypto coins are often classified by regulators as high-risk assets. This results in a substantially higher level of oversight by exchanges and may lead to additional restrictions on their use compared to conventional cryptocurrencies.

Volatility and market risks

High volatility is a characteristic feature of most cryptocurrency assets, including privacy coins. Privacy coins can fluctuate significantly in price, sometimes by double-digit percentages during periods of high market volatility. Additionally, due to their ambiguous legal status and regulatory risks, cryptocurrency privacy coins transaction fees vary by network; some privacy coins may have higher computational costs, but fees are not universally higher than those of non-privacy cryptocurrencies. There is also a persistent risk of a coin being delisted from an exchange following regulatory pressure, compliance costs, or internal exchange risk policies.

Safe usage and avoiding scams

Firstly, for safe use of any privacy coin​ you need to be cautious, because increased privacy of privacy coins can attract fraudsters due to the potential difficulty of tracking their activities.

Also, you need to be careful with e-commerce transactions (work only with trusted sellers) and always check websites for phishing, as it is common practice for fraudsters to disguise their platforms as legitimate services in order to steal funds.

Future of Privacy Coins

The future of privacy coins depends on the balance between the demand for financial privacy and regulatory pressure aimed at obtaining as much information as possible about financial transactions. Due to increasing regulatory oversight, it is possible that privacy coins will be removed from most exchanges.
