In recent years, privacy has become important to cryptocurrency traders. This need for privacy stems from concerns over the transparency and traceability which is present in many cryptocurrencies such as Bitcoin.
While these coins offer anonymity to some extent, they're not entirely private and this is why private coins have emerged as a solution to this, but what exactly is a privacy coin?
What Are Privacy Coins?
Privacy coins are a type of cryptocurrency designed to provide users with anonymity by hiding their blockchain transaction's origin as well as the destination.
Unlike regular crypto, which display transaction details publicly, privacy coins use certain techniques to hide transaction details such as recipient's address, sender's address and amount sent or received. The goal is to ensure that no one can trace or link transactions back to specific individuals, thereby preserving financial privacy.
The main aim is to protect users from security breaches, surveillance and exploitation by coming up with a way to engage in transactions discreetly.
How Privacy Coins Work
Privacy coins use different strategies to make transactions untraceable. These strategies include ring signatures, stealth addresses, zk-SNARKs and CoinJoin.
● Ring signatures: Ring signatures are a cryptographic method used by Monero to hide the identity of the sender of a transaction. When a transaction is initiated, the sender's actual signature is combined with many other signatures on the blockchain. This makes it puzzling to determine which signature belongs to the sender, thereby keeping their identity hidden.
● Stealth Addresses: This technique is used to make sure a recipient's address stays hidden in a transaction. The sender is required to generate a one-time address every time a transaction is initiated. This makes it difficult to link any transaction to the receiver. One of the top rated privacy coins, Monero, uses this strategy.
● zk-SNARKs: zk-SNARKs stands for Zero-Knowledge Succinct Non-Interactive Argument of Knowledge and it is used by Zcash to allow users to prove that a transaction is valid without revealing any details about it. This means that participants in a transaction can confirm its validity without having to reveal the transaction amount or any information about the recipient or the sender.
● CoinJoin: This is used to merge transactions from various individuals into a single transaction and then redistribute the funds to the individuals using different addresses.
Key Features of Privacy Coins
Privacy coins have some basic set of features which sets them apart from other cryptocurrencies.
The first of these features is that it obscures transaction details. They do this by providing little to no information about transactions.
Anonymity is another crucial feature. They shield users’ identities by hiding all relevant information such as wallet addresses and connections between transactions.
Are Privacy Coins Legal?
There is no definite answer concerning the legality of privacy coins because it all depends on individual jurisdiction, which means it could be illegal or legal depending on where you reside.
Privacy coins have not either been banned or endorsed in most places in the world, meaning their operation operates within a grey area in law.
However, in countries like South Korea, the government has banned the use of privacy coins in order to curb money laundering. It is believed that privacy coins can promote illegal activities such as money laundering and terrorism financing and this has led to a rise in the number of government agencies restricting the use of privacy coins.
Conclusion
Privacy coins can be viewed as a significant step forward in efforts to promote anonymity and privacy in the crypto space. They provide users with the opportunity to make transactions discreetly and avoid oversharing details in a bid to reduce security breaches and exploitation.
While there is no solid concrete evidence that proves privacy coins are used in funding illegal activities, they're not widely accepted because of their controversial nature.
