Should You Use Them? – Cryptopolitan

Cryptocurrencies are often associated with privacy. But most coins offer little in terms of privacy protection for users. That’s why many crypto enthusiasts have turned to crypto privacy tools and services to help protect their financial assets and keep transactions private. In this guide, we will look at some of the most popular crypto privacy tools and explore how they can protect personal information and financial assets.

Zero-Knowledge Proofs

Zero-knowledge proofs (ZKPs) are a type of cryptographic technology that allows two parties to verify information, revealing no additional details. You can use this technology in cryptocurrency transactions to ensure that both sender and receiver remain anonymous.

Zero-knowledge proofs provide a much-needed tool for the Web3 movement, one which ensures privacy and helps blockchains reach higher levels of scalability. Several platforms are already taking advantage of these roll-up proofs, which bundle multiple transactions and reduce transaction verification times by verifying just the proof. Not only can this speed up transactions significantly and make them more secure, but by reducing the overhead associated with validating transactions, it also allows blockchain platforms to expand their offerings into higher throughput movements. Zero-knowledge proofs can undoubtedly take us one step closer to the vision of Web3.

Stealth Addresses

Stealth addresses allow users to generate a unique one-time address for every transaction, meaning they can only spend the funds once and they hide all information about the sender, receiver, and amount.

Zcash stands out from other cryptos thanks to its use of stealth addresses. Zcash generates new addresses each time someone sends or receives funds and can’t get tied back to any other wallets. This ensures that they keep users anonymous while making transactions, safeguarding not only their transaction history but also the assets they have in custody. Best of all, Zcash lets users go even further by shielding the sending and receiving addresses and the amount being transferred so no one ever knows what’s actually being sent or where it’s coming from.

Ring Signatures

Ring signatures are another privacy-focused technology that enables users to sign transactions on the blockchain without revealing their identity. In a Ring signature scheme, a group of users can create digital signatures that appear to come from any of them.

They achieve privacy by combining personal keys with public keys, creating an exclusive mix of information that’s difficult to trace back to any specific user. Ring signatures are great for providing anonymity when dealing with cryptocurrency transactions.

One of the most notable implementations of Ring signature technology is Monero (XMR). Through this technology, Monero provides users with complete privacy and intractability when conducting transactions. This means that all the user’s data and funds are safe from prying eyes, allowing them to enjoy enhanced financial privacy.

Zether: A Privacy Coin on Ethereum

Zether is a privacy coin built on Ethereum that uses zero-knowledge proofs to verify transactions. Unlike other privacy coins, Zether supports both on-chain and off-chain transactions. This means that users can choose either public or private transaction types, depending on their needs. Zether also allows users to combine multiple transactions into a single atomic transaction, further increasing privacy and scalability.

Despite its privacy features, Zether still supports Ethereum’s existing smart contracts, allowing users to take advantage of these tools without sacrificing their privacy. This makes it a great option for businesses that need to keep their transactions confidential while still taking advantage of the power and flexibility of Ethereum.

Plasma: an interface for Ethereum side-chains

Plasma is an interface for Ethereum side-chains that uses smart contracts and a data structure known as a Merkle tree to store and verify transactions. By using Plasma, developers can deploy their own customized blockchains that are connected to the Ethereum mainnet. This allows them to take advantage of the security of Ethereum while creating their own applications on their own separate chains.

Plasma is great for developers who want to experiment with different blockchain applications without having to build everything from scratch. It’s also a powerful tool for businesses that need to keep their transactions and data secure, as only the relevant parties within a Plasma chain can view the details of the transactions. This means that users’ transactions are private regardless of the type of application that’s being deployed.


Mixers are a type of transaction obfuscation technology that works by pooling transactions together and mixing them up with other transactions on the blockchain. This makes it harder for third parties to link a particular transaction back to a specific user, thus providing increased privacy. Mixers are also great for allowing users to trade cryptocurrencies without having to reveal their identity or personal information.

The most popular type of mixer is the CoinJoin, which was pioneered by Bitcoin Core developer Gregory Maxwell. The protocol works by pooling transactions together and allowing multiple users to sign off on a single transaction. This creates an obfuscation layer that makes it difficult for third parties to track individual transactions within the pool. CoinJoin has become popular with privacy-focused users, as it provides enhanced security and anonymity when dealing with cryptocurrency transactions.

Coin Tumblers

Coin tumblers are like mixers, however, they work slightly differently. Instead of pooling multiple transactions together, coin tumblers use automated algorithms to jumble up the inputs and outputs of a transaction. This makes it difficult for third parties to track the coins, thus providing increased privacy when dealing with cryptocurrency transactions. Coin tumblers can also break up large amounts of funds into smaller ones, making it harder for third parties to detect suspicious activity on the blockchain.

Coin tumblers are a great way for users to keep their transactions private and untraceable, however, they typically require the user to pay a fee in order to use the service. This is because the tumbler needs to make sure that each of the coin’s transactions is safe, and they also need to cover their own operating costs. With that said, coin tumblers are still a great way for users to keep their transactions secure and anonymous when dealing with cryptocurrency.

An example of a coin tumbler is the service provided by Wasabi Wallet, which allows users to mix their coins in order to keep their transactions private. The wallet also enables users to track their coins and see which ones are mixed, making it easy for users to keep track of their funds.

Coin Shufflers

Coin shufflers are another type of privacy tool used for cryptocurrency transactions. They operate similarly to mixers, but instead of mixing your coins with others, they shuffle your coins and transfer in smaller increments so that it is harder to trace back to you or your transaction. Coin shufflers can also split up large amounts of money into smaller chunks, making it easier to move around without drawing unwanted attention.

Coin shufflers are great for users who want to keep their transactions and identity secure when dealing with cryptocurrency, as the smaller transfers make it harder for third parties to trace back a particular transaction. However, coin shufflers usually require you to pay a fee in order to use the service, so it’s important to factor that into your decision before using one.


Another way to improve the security and privacy of your cryptocurrency transactions is by using a virtual private network (VPN). A VPN works by encrypting all of your internet traffic, making it difficult for third-parties to snoop on your activity or see what you’re doing online. This makes it much harder for hackers and other malicious actors to track your cryptocurrency transactions, which can help keep you safe while dealing with digital assets.

VPNs are a great way to add an extra layer of security when dealing with cryptocurrency transactions, but it’s important to choose a reliable and secure provider for the best protection. Many VPN providers offer specialized features such as kill switches and automatic reconnection, which can help keep your online activity safe even if your internet connection drops.

Privacy Wallets

Privacy wallets provide enhanced security and anonymity for users. Privacy wallets operate by creating a new wallet address each time a transaction is started and using that address to send funds instead of the original wallet address. This makes it difficult for anyone to trace back your transactions or figure out your identity.

Privacy wallets are a great way to increase the security and privacy of your cryptocurrency transactions, but it’s important to choose one that is reliable and secure. Some of the more popular privacy wallets include Wasabi Wallet, Samourai Wallet, and Zcash. It’s also important to remember that these wallets can cost money to use, so it’s important to factor that into your decision before using one.

The Lightning Network

The Lightning Network is an open-source layer two protocol designed to add scalability and privacy to Bitcoin transactions.

Because of its decentralized and peer-to-peer nature, users can send payments without the knowledge of anyone other than the payer and payee.

The technology does not store lightning payments on any public ledger, making them incredibly secure. To add a layer of privacy to the Lightning Network, it leverages onion routing; this technique makes routed payments incredibly difficult if not impossible to track. With Lightning’s added security features, it has become a premier choice for those seeking high privacy while conducting digital payments.

Privacy Coins

Privacy coins are a type of cryptocurrency that employs advanced encryption techniques to ensure the highest level of privacy and anonymity. Popular examples of privacy coins include Monero, Zcash, and Dash. These coins offer superior security measures compared to more mainstream cryptocurrencies, such as Bitcoin or Ethereum. They typically use zero-knowledge proofs in order to prevent any third parties from snooping on or tracing transactions.

Privacy coins allow users to obfuscate the number of funds being transacted and who is sending or receiving them.

5 Risks associated with crypto privacy tools

1. Security risks: Cryptocurrency privacy tools are only as secure as the platform, so it is important to choose a provider that has strong security measures in place.
