Crypto and Privacy: Securing Your Identity On-Chain

Cryptocurrency has undoubtedly changed the face of finance for better or for worse—but as with any nascent technology, it comes with a host of issues surrounding privacy. 

Blockchain technology is a complex world wherein financial transactions are immutably etched on a public ledger forever—but its inherent transparency, by design, might unintentionally reveal more than an individual wants. 

Crypto is a high-stakes tightrope walk straddling the line between financial privacy and transparency which could lead to tension for individuals who wish to keep their identities private and their activities secure from prying eyes when transacting on-chain.

This article discusses the nuances involving crypto and privacy in the present day, and how to secure your on-chain identity and privacy.

Privacy concerns in blockchain technology

Unlike traditional financial systems, which generally rely on layers upon layers of intermediaries and central scrutinizers, crypto relies on blockchain technology designed to decentralize and devolve control to users. 

Blockchain was designed to be resistant to tampering or fraud because of its pseudonymous and transparent nature—but its pseudonymity and transparency raises serious questions about privacy.

With the internet democratizing and supercharging the speed with which digital information is accessible to anyone and everyone, blockchain technology aims to do the same for the exchange of value over the internet.

And therein lies the rub. Data stored on the blockchain is NOT encrypted or private by any stretch of the world. 

Imagine using a financial system where all salary data, sensitive business data, information traceable to an individual entity, or legal contract details were readily available on a public ledger. Sounds like a nightmare from 1984, doesn’t it? 

Well, that’s exactly how the state of blockchain technology is right now. And it is for this reason why blockchain technology and crypto is having a difficult time gaining serious adoption besides speculation.

Understanding cryptocurrency and blockchain

Cryptocurrency uses cryptographic techniques to act as a digital medium of exchange. All crypto is powered by blockchain technology, using an open, decentralized, and immutable public ledger maintained by a network of computers.

Each crypto transaction is recorded within a block connected to a chronological “chain” of previous blocks that are recorded forever and cannot be reversed or tampered with, hence the term “blockchain.” Blockchain architecture is designed to ensure transparency and pseudonymity, enabling transaction verification without the need for a centralized intermediary to review and approve them. 

While the transparency and immutability of the blockchain is one of its most defining features, it is open to a host of potential vulnerabilities that can be exploited by threat actors. 

Once a transaction is verified and recorded, these are permanently recorded on the blockchain, which may reveal more information than a user wants.

Anonymity vs. pseudonymity on-chain

The bedrock of blockchain privacy is the use of cryptographic keys that users use to interact with the underlying blockchain infrastructure. Each participant in a particular blockchain ecosystem holds a public key (which can be seen as a publicly-available address), and a private key, which serves as a digital signature that enables users to sign off on transactions. 

Public keys are openly shared to receive funds or validate transactions, while private keys are supposed to remain strictly confidential as they authorize access to transactions involving the individual’s crypto assets.

The clear distinction between private and public keys is the key ingredient of blockchain’s pseudonymity. Instead of complete anonymity, all transactions are linked to public keys while protecting personally-identifiable information. 

While that appears to be safe, it’s worth mentioning again that while personal details may not be readily visible, transaction histories, patterns, and balances are visible by default and can be analyzed by crypto sleuths and blockchain analytics solutions. 

While real-world identities aren’t readily accessible, a crypto wallet’s holdings, transaction history, and transaction patterns can be linked to individual entities over time. 

Therefore, the uneasy balance between transactional privacy and transparency makes it nigh impossible to guarantee 100% on-chain anonymity, presenting a host of opportunities and challenges for privacy-focused individuals.

Why does anonymity matter?

Here are some key reasons why many individuals demand anonymity:

• To avoid being targeted for financial crimes, fraud, and scams. If threat actors can see your financial history, behavior and balances you are an easy target for a variety of scams.
• To prevent identity theft/doxxing. Personally-identifiable information linked to your crypto accounts can be misused by threat actors to apply for loans, credit cards, or commit other types of ID fraud. Moreover, identities can be exposed over time, and centralized exchanges, which serve as a major on-ramp for investors, could be exploited by hackers to link wallets to real-life identities. 
• To avoid misinformation and price manipulation. If whales know you have big positions in a particular cryptocurrency, it could be used against you to get you to sell or buy to their advantage.

Ultimately, privacy and anonymity are crucial for a sound, secure, and open financial system. Granted, while some degree of regulation and compliance will be required, more crypto users should disabuse themselves from the notion that crypto is completely anonymous and private—and defend their right to privacy. 

The more people are aware of blockchain’s inherent limitations on privacy and the more steps they take to protect it, the harder it is for threat actors from snooping on their activity!

How to Keep On-Chain Privacy: Solutions

Solutions to protect on-chain privacy have been around since the advent of crypto, but not all have stood the test of time. 

Here are the ways privacy-focused investors could retain some semblance of on-chain privacy : 

• Privacy coins. Privacy coins like Monero and Zcash use private ledgers and zero-knowledge proofs to protect source and destination addresses from being publicly available. However, many privacy coins, including Monero, have been delisted from centralized exchanges due to regulatory concerns and potential misuse. 
• Crypto mixers. Crypto mixers pool crypto transactions from different sources before sending them to their destination addresses. This obfuscates the original source of the crypto from that of the ultimate recipient. However, crypto mixers are risky, and using them could lead to the loss of part or all your funds. Moreover, law enforcement agencies have been cracking down on crypto mixers, shutting them down, and charging their operators to the fullest extent of the law. 
• Private swap platforms. Private swap platforms like Houdini Swap have been enabling crypto swaps that keep the sender’s address private. Paired with a way to buy cryptocurrency anonymously Houdini Swap enables the best possible privacy technology allows.

The Future of Crypto and Privacy

More and more users become aware of the importance of privacy. Meanwhile, countries are constantly evolving their regulatory frameworks while straddling the balance between cracking down on financial crime and enabling the technology to evolve. 

The crypto industry, as a whole, is on the hot seat as to whether they could navigate an increasingly complex regulatory environment while promoting constant innovation.

For instance, in the European Union, legislators will need to balance the requirements of the General Data Protection Regulation (GDPR) and efforts of law enforcement agencies in combating financial crimes. 

In the United States, efforts are underway to synergize federal privacy legislation with local state laws that could point the way forward to a more rational policy for the entire crypto sector.

Thus far, Houdini Swap has become the leading privacy swap platform of choice for individuals who wish to keep their transactions discreet in a completely above board manner and full compliance with regulations.
