Bitcoin has been praised for its improved security over traditional currencies. However, using bitcoin is definitely not the most private or anonymous way to carry out transactions. The creators of some altcoins have stepped up to attempt to provide a form of digital currency that offers more privacy and anonymity.

Dubbed ‘privacy coins,’ these altcoins are often associated with darknet markets and illegal activities, but there are plenty of legal reasons for wanting to maintain privacy. Whether you want to keep personal transactions private or you run a business and need to conceal transactions from prying eyes, anonymity is key.

With privacy coins becoming increasingly advanced, you have plenty of options. Monero, zcash, dash, xeonbit are four of the popular altcoins that offer superior anonymity to bitcoin. They each have their own pros and cons and there is debate about which is the most anonymous. In this post, we explore each of these altcoins and compare them to decide which offers the best option for those seeking more anonymity.

Before we jump into the four altcoins, we’ll take a look at the meaning of anonymity in terms of cryptocurrencies. Since it’s the most widely known cryptocurrency, bitcoin serves as a good point of reference.

Bitcoin is lauded for providing improved security over fiat transactions. When we talk about security here, it essentially refers to the difficulty involved in someone stealing or copying coins. The improved security is due to the nature of blockchain technology. It would take a group of miners with at least 50% of the mining power to include a false transaction in a block.

Every block in the chain includes the hash of the last, which makes changing past blocks extremely difficult. So with each block that is added to the chain, every past transaction becomes increasingly secure. Even the latest block to be added to the chain would be difficult to tamper with and each one before it more so. Security has been improved upon with some altcoins but bitcoin is still considered solid from this standpoint.

On the other hand, it’s largely agreed upon that bitcoin isn’t all that private or anonymous. Every transaction, including the wallet addresses of the sender and recipient, amount, date, and time, is stored on a public ledger. It can be considered pseudonymous because names aren’t actually listed, but it would be fairly easy to trace most wallet addresses to their owner using clues like IP address and transaction history.

While it is possible to make bitcoin transactions more anonymous, it does require a fair amount of effort in the form of coin mixing. In the context of bitcoin, coin mixing is often referred to as coin tumbling or laundering. It involves mixing coins from multiple parties in order to break the connection between the sender and recipient. If done properly, it can make transactions virtually impossible to trace.

To mix coins properly involves various steps including creating multiple fresh wallet with new burner email addresses. The process can be cumbersome and time-consuming, especially if you’re mixing on a regular basis.

For ongoing anonymity, it makes more sense to go with a cryptocurrency that provides an in-built option for anonymous transactions without the added fuss. Even with these, you likely still need to take additional precautions such as using an anonymizing browser example Tor.

One more problem with bitcoin we haven’t yet addressed is its lack of fungibility. When a coin is fungible, every unit is interchangeable and doesn’t have a particular history tied to it. Since every bitcoin is traceable (unless it has been mixed), some bitcoin could have a lower perceived value than others if it has been used in something illegal, for example, a theft, hack, or ransomware attack. This is known as ‘taint.’

Improvements made by the creators of some altcoins to make the cryptocurrency more anonymous also makes it fungible. This way, users don’t have to worry about tainted coins and subsequent loss of value or rejected transactions.

As mentioned earlier, privacy coins have been linked to criminal activity, from tax evasion to drug dealing, but there are plenty of legal reasons for wanting to keep transactions anonymous. You probably wouldn’t want the world to be able to view your bank statements and cryptocurrency transactions shouldn’t be any different.

A couple of specific cases in which you may want to go anonymous are when paying for a private medical procedure or service, such as cancer treatment or psychotherapy, or making an anonymous donation to charity.

There are also various general reasons you may want to maintain anonymity:

• Stop advertisers building a profile around your spending habits
• Keep your net worth under wraps
• Prevent malicious hackers and other cyber criminals accessing your information
• Simply prevent the world from seeing where you shop, eat, and vacation

And these are just on a personal level. The implications for businesses dealing with things like trade secrets or a private list of clients could be much broader.

Now that we know what we’re looking for in terms of anonymity, let’s see what these three coins have to offer.

Dash is one of the older altcoins on this list, having been launched in 2014. It was originally named xcoin, then darkcoin, before becoming dash in 2015. It is known for its fast transactions speeds, a quick four seconds compared with bitcoin’s ten minutes. One might assume that’s where the name came from, but dash is simply short for ‘digital cash.’

Dash has other factors that differentiate it from the bitcoin network, including how decisions are made. Any changes to bitcoin require unanimous approval from members of the network. Dash instead uses a voting system which means that changes can be made quickly.

Another notable difference between this altcoin and bitcoin is the operation of the network. There are two main tiers, the miners and the ‘master nodes.’ The miners carry out similar functions to those in the bitcoin network. The master nodes are responsible for governance functions and for carrying out special transactions — InstantSend and PrivateSend.

InstantSend enables near-instantaneous transactions and is claimed to prevent double-spending, a potential problem with other cryptocurrencies. Regular block times are two and a half minutes whereas InstantSend transactions can be processed in under a second.

Dash is traded on various exchanges and is included in many cryptocurrency payment networks and debit cards. It can also be found in certain US ATMs and at post office branches in Austria. It’s the most widely adopted (mainstream) cryptocurrency of the three.

Dash privacy and anonymity

PrivateSend transactions are where dash gets its reputation for being one of the most anonymous altcoins available. This privacy initiative uses coin mixing to improve anonymity. As mentioned earlier, mixing bitcoin can be a bit of an inconvenience, especially if done regularly.

In the case of dash, when users take advantage of the PrivateSend function, the mixing is carried out for them and coins are deposited in new addresses. By the end of the process, the origin of the coins is obfuscated. This also makes the currency somewhat fungible, but only when PrivateSend is used.

PrivateSend can be initiated at the click of a button, but there are fees involved. (Source: Dash)The main questions here pertain to how reliable this service is and whether it will really help you remain anonymous. One of the main critiques is that you can still see the receiver of the coin. The whole network isn’t private, just the PrivateSend function. So if you send coins, you’re reliant on the recipient of the transaction using the PrivateSend feature if you want to break the connection. Basically, if anonymous transactions are connected to non-private ones, there’s potential they could be traced.

Monero was created in the same year as dash and origniated as a fork of bytecoin. There was some negative press surrounding bytecoin at the time, with critics dubbing it “shady.” This was mainly due to the fact that a large majority of coins were pre-mined and granted to an unknown group of creators and stakeholders.

Nonetheless, monero, which is based on the same CryptoNote protocol that bytecoin was, gained popularity fairly quickly, its market cap peaking (subject to the time of writing) at almost $7 billion at the beginning of 2018. In fact, it was the best performing cryptocurrency of 2016 in terms of market cap, although this has been attributed to its popular use in criminal activity.

The network is based on blockchain technology similar to that of bitcoin, with one of the main differences being that blocks are mined every two minutes. Although it has gained most of its fame from its privacy features, monero does address usability issues inherent in some networks. For example, instead of simply having a cap on block size, it issues penalties to prevent miners from trying to manipulate the system.

Monero is difficult to purchase with fiat currencies although it is traded for both EUR and USD on Kraken and for USD on Bitfinex. It can be found on multiple exchanges for purchase with other cryptocurrencies. Some merchants accept monero as a form of payment and it’s included in various coin payment platforms such as Binance and Evercoin. As mentioned, the place you’re most likely to see it accepted directly is within darknet marketplaces.

Monero privacy and anonymity

Confidential transactions were introduced to the monero network at the beginning of 2017 through the use of ring signatures as an optional part of the protocol. They became mandatory in September 2017.

A ring signature involves additional possible senders (mixins) for each transaction. This means that the actual sender could be one of two or more people. What’s more, transactions are broken up into separate amounts so that one transaction actually occurs as multiple, going to different ‘stealth addresses.’ This negates the possibility of someone tracing a sender or recipient based on personal details attached to their wallet address. However, critics have identified flaws in the system and claim that transactions can be traced.

A potential issue if you’re thinking about using monero is that it’s getting a bad reputation for increased popularity with criminals. It was reportedly the ransom currency of choice in the Wanna Cry ransomware attack of 2017 and has been a feature of other major attacks since. That being said, its widespread use in criminal activity is actually considered testament to its privacy and anonymity. Monero is fungible so tokens don’t lose their value if they’ve been used in shady transactions.

Bear in mind, similar negative press has been earned by bitcoin in past years. Plus, given the chance, a newer coin like zcash could be catapulted to notoriety within the criminal underground very soon. The point is, if something can be used for both good and bad, it likely will be.

Zcash is having only been around since October 2016. Developed by a reputable team of scientists and cryptographers, it didn’t take long for this coin to join the wave of crypto success stories and reach a peak of more than $2.5 billion in market cap earlier this year.

It hasn’t exactly made its way into the mainstream just yet, but it can be exchanged for fiat currencies on a few exchanges including Kraken, Bitfinex, and CEX.io. It can be easily purchased with other cryptocurrencies on exchanges like Binance.

Xeonbit is the youngest of these three privacy coins. The team behind a private digital currency for secure payments says its goal is to make every consumer their own bank — enabling them to send and receive crypto with the gadget of their choice.

The company believes that there is a plethora of use cases for view keys. While charities could deliver transparency to their supporters, businesses will be able to achieve regulatory compliance by opening up their accounts for auditing. It is even suggested that children could have their own accounts for spending pocket money, with parents using view keys to monitor their transactions.

Xeonbit Token branching out

Looking ahead to its plans for the future, Xeonbit says it is determined to introduce more merchants to its ecosystem, helping to strengthen the use case for its cryptocurrency.

The company believes that XNS has the potential to make its transaction fee five times cheaper and up to 100 times faster for merchants to accept payments using its cryptocurrency.

In the coming months, the project hopes that its decentralized marketplace based on a third-party protocol will be ready to launch, while the xeonbit token will be able to be traded on Binance DEX and more decentralized exchanges by the end of the year.

All of these cryptocurrencies offer advantages over bitcoin when it comes to privacy and anonymity. So which one should you choose?

• Xeonbit: This is new in market and may take time for proving. Moreover, that’s a strong point for it while the market value is still low for HOLDER. Xeonbit mission is creating more true value for community while protecting privacy for its users.
• Dash: This altcoin is more accessible and widely accepted (outside the darknet) than the others. But it only offers increased privacy and anonymity through its PrivateSend feature. This could be a more suitable option for those looking for something that is easy to spend and who need occasional anonymity.
• Monero: This coin is hampered by a bad reputation and accusations that transactions are traceable. Although, it has been in use for a relatively long period and has proven success in marketplaces (albeit some illegal ones).
• Zcash: This one provides increased privacy through its underlying protocol, meaning less traceability. If used properly, i.e. with an anonymizing browser, it appears to be the most anonymous option overall. But it doesn’t have experience on its side which may put some users off.

Your choice could depend on various factors, including your use case or even how much faith you have in the creators of each coin. It’s worth bearing in mind that the protocols and systems behind each coin are in constant development. As such, one that is missing the mark right now might be rolling out improvements very soon. Indeed, if you take a look at forums on the topic, you’ll find some ongoing debates about which offers the most privacy and anonymity.
