Cryptocurrency and Privacy: What’s the State of Affairs Today?
With the advancement of technology, the process of data exchange has become faster, more convenient, and… safer? Unfortunately, the latter point has become questionable. Nowadays, data leaks have become more frequent. Such accidents have led society to the well-known fact: the Internet is far from the safest place for exchanging information.
Is there any solution to this problem? In fact, there is one. The answer lies in technology, specifically blockchain. Let’s figure out what is the level of privacy in Crypto World and if cryptocurrency is truly as safe as many consider it to be.
How can blockchain protect user data?
Blockchain is a distributed ledger system that doesn’t adhere to a single central authority. Protection of data here becomes possible due to two main mechanisms:
- Cryptographic encryption.
- Decentralized storage of information.
Advantages of blockchain in ensuring privacy:
- Transparency
Data exchange in blockchain occurs in the form of transactions, and all information about them is stored in a public ledger. This means that any network user can see the entire process of data movement from point A to point B. All errors, intentional manipulations, and forgeries will also be visible to everyone.
- Decentralization
The protection of personal data in blockchain is mainly achieved due to the decentralization of the system. The absence of a single control node complicates (and ideally excludes) the possibility of data falsification or theft.
- Immutability
Transactions made in blockchain cannot be altered or deleted after they are closed. This ensures both data security and integrity.
- User Control
The aforementioned features enable users to independently control their personal data without transferring responsibility for them to third-party governing bodies.
Cryptocurrency Anonymity: Fact or Conditionality?
In 2008, the world saw the emergence of the first anonymous decentralized payment tool — Bitcoin (BTC). It was envisaged that it would become an opponent to the entire centralized system of traditional finance.
So initially, Bitcoin was mined, and users had the right not to disclose their personal data when making transactions. All that was needed was a cryptocurrency address — a combination of letters and numbers. Everything collapsed when cryptocurrencies ceased to be decentralized. Or rather, some part of crypto assets still adheres to the ideals of decentralization, but the majority fell under the “market conditions”.
Some of the benefits in the Crypto World are now provided precisely due to centralization and control by “higher authorities”, be it governmental regulators or major players in private business. In such conditions, maintaining confidentiality becomes difficult to uphold completely. Due to the distributed ledger, exposing one node can easily lead to the de-anonymization of all other participants in the chain.
How to maintain data confidentiality in the Crypto World?
Moving away from unconditional decentralization is a natural consequence of crypto industry development. Technologies become more complex, companies multiply every day, and data volumes grow. Protecting personal information in such a vast space is difficult, but possible. It’s enough to remember the basic rules:
1. Change cryptocurrency addresses more often.
2. Minimize interaction with centralized exchanges (CEX).
3. Ensure secure storage of the seed phrase.
4. Track transactions manually.
5. Avoid leakage of personal information
As we can see, privacy still exists in the crypto space. Preserving it today requires a bit more effort than, say, 15 years ago, but nonetheless, keeping one’s data safe is possible. The key is to observe security measures and not unnecessarily jeopardize oneself and one’s assets.
