For years, one of crypto’s biggest selling points was transparency.
Every transaction could be verified.
Anyone could check the blockchain.
Nobody had to trust a bank or payment processor to tell them what happened.
That’s still incredibly powerful.
But there’s another side to complete financial transparency that becomes increasingly obvious as more money moves onchain.
Do you really want everyone to see your money?
Your salary.
or investments.
Even purchases.
Your trading positions.
And wallet balance.
And potentially years of financial history connected to all of them.
Probably not.
That’s why crypto privacy is becoming interesting again.
I’ve always had a soft spot for Monero. It took the privacy argument seriously long before it became fashionable again.
But if you’ve been watching Crypto Twitter lately, it feels like the market has increasingly picked Zcash as the more exciting privacy trade.
Both are interesting.
And yes, from a trading perspective, privacy coins becoming a narrative again could create opportunities.
But I think the bigger story is happening underneath the token prices.
Privacy is increasingly becoming infrastructure.
Zero-knowledge proofs, confidential transactions, private stablecoin payments and selective disclosure are creating ways to bring privacy to ordinary blockchain applications.
The future of crypto privacy might not simply be choosing between Monero and Zcash.
Privacy could eventually become something we expect from every blockchain.
Why Aren’t Blockchains Private?
This is one of the first misconceptions beginners have about cryptocurrency.
Bitcoin is anonymous, right?
Not really.
Bitcoin is better described as pseudonymous.
Your Bitcoin address doesn’t automatically contain your name, passport number or home address.
But your transactions are public.
Anyone can see funds moving between addresses.
Ethereum works similarly.
Wallet balances, token transfers, swaps and interactions with smart contracts can all leave a public trail.
If nobody knows who owns a wallet, that information might initially appear anonymous.
The problem begins when your identity becomes connected to an address.
Maybe you withdraw crypto from a regulated exchange.
Or you publish an ENS name.
Potentially someone sends you money.
Maybe you post your wallet publicly.
Maybe sophisticated blockchain analytics connects several wallets through transaction patterns.
Once that connection exists, your supposedly anonymous blockchain history can suddenly become much easier to follow.
Crypto gives us transparency.
It doesn’t automatically give us privacy.
Why Financial Transparency Can Become a Problem
Imagine receiving your salary onchain.
Your employer sends stablecoins to your wallet every month.
Sounds convenient.
Now imagine buying coffee with that same wallet.
Depending on how the payment system is structured, the merchant could potentially inspect your wallet history.
They might see how much money you have.
Or could see other payments you’ve received.
They might identify your investments.
Perhaps they can even estimate your salary.
That’s obviously not how normal financial privacy works.
When you pay for dinner with your bank card, the restaurant doesn’t receive access to your bank balance and transaction history.
Blockchain transparency can create exactly that problem.
And the problem becomes much larger when companies enter the picture.
Institutions Can’t Put Everything on a Public Blockchain
Imagine you’re running a large company.
Your treasury operates onchain.
Every supplier payment is visible.
Every customer payment is visible.
Competitors can monitor your balances.
Traders can potentially see assets moving before major transactions.
Suppliers could determine what you’re paying other suppliers.
Everyone can analyze your financial activity in real time.
That’s not particularly attractive.
This is one reason onchain privacy could become increasingly important as traditional financial institutions experiment with blockchain infrastructure.
Companies need confidentiality.
Banks need confidentiality.
Investment funds need confidentiality.
Normal people need confidentiality.
That doesn’t necessarily mean they need complete anonymity.
And that distinction could define the next generation of crypto privacy.
Monero: Privacy by Default
If we’re talking about crypto privacy, we have to start with Monero.
Monero has been around since 2014 and was designed around a simple principle:
Transactions should be private by default.
Bitcoin allows anyone to inspect transactions on its public ledger.
Monero uses several cryptographic techniques to obscure important transaction information.
These include ring signatures, stealth addresses and confidential transaction technology.
The result is that outside observers can’t easily determine who sent a transaction, who received it or how much was transferred.
Users don’t have to activate a special privacy mode.
Privacy is built into the system.
That’s one reason I’ve always found Monero interesting.
It has a very clear purpose.
Monero isn’t trying to become an AI blockchain, gaming chain, RWA platform, memecoin casino and decentralized social network simultaneously.
It’s private digital money.
Simple thesis.
Why Has Monero Been So Controversial?
Unfortunately, Monero’s biggest strength is also its biggest problem.
Regulators don’t particularly like financial systems they can’t easily monitor.
Crypto exchanges have faced increasing pressure around privacy coins, particularly in jurisdictions with strict anti-money-laundering requirements.
As a result, Monero has been delisted from several major centralized exchanges over the years.
That’s significant.
Removing exchange access reduces liquidity and makes buying or selling XMR more difficult for mainstream users.
There’s also the reputation problem.
Privacy technology inevitably gets associated with criminals, darknet markets and money laundering.
Those uses exist.
But saying privacy is only useful to criminals is a weak argument.
We don’t publish our bank statements online.
We don’t allow strangers to inspect our credit-card history.
And companies certainly don’t reveal every internal financial transaction to their competitors.
Privacy itself isn’t suspicious.
The difficult question is how crypto can provide legitimate financial privacy while still satisfying regulatory requirements.
We’ll come back to that.
Zcash Takes a Different Approach
Then we have Zcash.
Zcash launched in 2016 and approaches blockchain privacy differently.
Instead of making every transaction private by default, Zcash allows users to interact using transparent or shielded transactions.
The technology underneath those shielded transactions is particularly important.
Zcash was one of the earliest major cryptocurrency projects to demonstrate the practical potential of zero-knowledge proofs.
In simple terms, zero-knowledge technology allows someone to prove that something is true without revealing all of the underlying information.
That’s an extremely powerful concept.
You might prove that a transaction is valid without publicly revealing every detail of the transaction.
And the importance of that technology now extends far beyond Zcash itself.
Monero vs Zcash: Which Privacy Coin Won?
If you asked me historically which privacy coin I liked, I’d probably say Monero.
Its proposition is straightforward.
Privacy is always on.
But markets don’t necessarily care about my philosophical preference.
Recently, Crypto Twitter seems to have picked Zcash as the hotter privacy narrative.
ZEC has attracted renewed attention from traders as privacy returns to the crypto conversation.
That makes both assets interesting from a trading perspective.
Monero represents the pure privacy-money thesis.
Zcash represents privacy combined with zero-knowledge technology that increasingly resembles where the broader blockchain industry is heading.
But I don’t think the most important question is:
Will XMR or ZEC win?
The more interesting question is whether the technology pioneered by privacy projects eventually spreads throughout crypto.
Because that’s already happening.
What Are Crypto Mixers?
Privacy coins aren’t the only way people have tried to achieve financial privacy onchain.
Another approach is a crypto mixer.
Mixers attempt to break the obvious connection between the address sending cryptocurrency and the address receiving it.
Instead of funds simply moving:
Wallet A → Wallet B
they enter a larger pool or privacy system involving many transactions.
That makes tracing the original source more difficult.
Tornado Cash became the most famous example on Ethereum.
Users could deposit assets into a smart contract and later withdraw them to another address while using zero-knowledge technology to prove they were entitled to the funds without publicly linking the deposit and withdrawal addresses.
Technically, it’s fascinating.
Legally, it became extremely controversial.
Why Crypto Mixers Became a Regulatory Battleground
Mixers demonstrate the central conflict surrounding crypto privacy.
The same technology that can protect an ordinary user’s financial information can also be used by someone trying to hide stolen funds.
Hackers have repeatedly used mixing services to obscure transaction trails.
That attracted attention from regulators and law enforcement.
Tornado Cash eventually became the center of one of crypto’s biggest privacy battles.
And the debate exposed a much larger question.
Should privacy technology itself be treated as suspicious because criminals can use it?
Cash can be used illegally.
Encrypted messaging can be used illegally.
The internet can be used illegally.
That doesn’t mean the underlying technology has no legitimate purpose.
Still, regulators aren’t going to simply ignore money laundering because crypto users value privacy.
The industry needs another solution.
That’s where newer privacy technology becomes particularly interesting.
Zero-Knowledge Proofs Could Change Crypto Privacy
Zero-knowledge proofs sound complicated.
The basic concept isn’t.
Imagine you need to prove you’re over 18.
Normally, you might show someone your ID.
But your ID reveals much more information than necessary.
Your full name.
Birth date.
Photograph.
Maybe your address.
The person only needed one piece of information:
Are you over 18?
A zero-knowledge proof could theoretically allow you to prove the answer is yes without revealing all of the additional information.
Now apply that idea to finance.
You could potentially prove that:
A transaction is valid.
You have enough collateral.
You’re not on a sanctions list.
You meet certain regulatory requirements.
You have sufficient funds.
Without revealing your entire financial history.
That’s a much more interesting model for mainstream crypto privacy

Selective Disclosure Could Be the Middle Ground
This is where selective disclosure becomes important.
Traditional privacy coins generally focus on hiding transaction information from public view.
Future financial systems could be more nuanced.
Imagine your transactions remain private to the general public.
Your neighbor can’t inspect them.
Random people on X can’t inspect them.
Competitors can’t inspect them.
Blockchain analytics companies can’t simply build a complete public profile from every transaction.
But when legally required, you can prove specific information to a regulator, auditor or financial institution.
Not everything.
Only what’s necessary.
That could provide privacy without creating a completely opaque financial system.
For institutions, this may be the difference between blockchain technology being interesting and actually being usable.
Confidential Transactions Are Coming to Regular Blockchains
Another important development is that privacy is no longer limited to dedicated privacy coins.
Major blockchain ecosystems are experimenting with ways to make ordinary transactions confidential.
Zero-knowledge technology can hide transaction details while still allowing the blockchain to verify that everything is valid.
Other cryptographic approaches are also being developed.
One increasingly discussed technology is fully homomorphic encryption, or FHE.
FHE potentially allows computations to be performed on encrypted information without first revealing that information.
That’s pretty wild.
Imagine a DeFi protocol processing financial information without the underlying data becoming publicly visible.
We’re still early.
But this is where crypto privacy starts becoming infrastructure rather than simply a category of coins.

Privacy-Focused L2s and Apps Could Be the Next Step
Ethereum and other smart-contract networks don’t necessarily need to become completely private at the base layer.
Privacy can also exist higher in the stack.
Layer 2 networks can provide privacy.
Wallets can provide privacy.
Applications can provide privacy.
Payment systems can provide privacy.
Stablecoins can potentially incorporate privacy features.
This means users might eventually interact with private blockchain applications without even thinking about the cryptography underneath.
That’s usually what happens when technology matures.
Most people using HTTPS don’t understand the encryption protecting their browser connection.
They don’t need to.
Crypto privacy may eventually work the same way.
Stablecoins Make Crypto Privacy More Important
Stablecoins might actually be one of the strongest arguments for better blockchain privacy.
Crypto traders are comfortable moving USDC and USDT around public wallets.
But imagine stablecoins becoming ordinary money.
Your salary arrives in stablecoins.
You pay rent in stablecoins.
You buy groceries with stablecoins.
Your company pays employees in stablecoins.
Businesses settle invoices in stablecoins.
Suddenly, transaction privacy isn’t some niche concern for cypherpunks.
It’s basic financial infrastructure.
People aren’t going to accept a financial system where buying lunch potentially exposes their savings account.
If stablecoins continue moving toward mainstream payments, privacy needs to improve alongside them.
Institutions May Be the Biggest Driver of Onchain Privacy
Ironically, institutions might ultimately push crypto toward more privacy than retail users do.
Retail crypto users have tolerated transparent blockchains for years.
Institutions have much more to lose.
Imagine a hedge fund placing large trades while competitors monitor every wallet.
Or a company negotiating an acquisition while treasury movements are visible onchain.
Imagine banks exposing client transaction flows.
It doesn’t work.
Institutional blockchain adoption therefore creates demand for two things that initially seem contradictory:
Transparency and privacy.
Institutions want proof that transactions are valid.
They don’t necessarily want the underlying financial information exposed publicly.
Cryptography may allow both.
That’s why privacy is increasingly becoming part of the institutional blockchain conversation.
Can Crypto Privacy and Regulation Coexist?
This might be the biggest question.
Governments aren’t going to accept financial infrastructure that makes sanctions enforcement and anti-money-laundering rules impossible.
Crypto users aren’t going to accept complete financial surveillance either.
The long-term solution probably exists somewhere between those extremes.
Selective disclosure is one possibility.
Zero-knowledge identity systems are another.
Users could potentially prove that they satisfy certain requirements without publicly revealing their identity or transaction history.
For example:
Prove I’m not sanctioned without revealing who I am to everyone.
Or:
Prove these funds passed compliance checks without exposing every transaction I’ve ever made.
That’s fundamentally different from simply making everything invisible.
And it could make privacy compatible with regulated financial markets.
Privacy Coins Could Still Have Their Moment
None of this means Monero and Zcash suddenly become irrelevant.
Actually, the opposite could happen.
If privacy becomes one of crypto’s major narratives again, traders will naturally look toward the assets most closely associated with it.
Monero is the obvious privacy-money trade.
Zcash is closely associated with zero-knowledge privacy and has already attracted renewed attention.
That makes both interesting to watch.
But narratives move quickly.
A token pumping doesn’t necessarily mean its technology becomes the industry standard.
We’ve seen that plenty of times in crypto.
Personally, I’m interested in both the trade and the underlying technology.
Those aren’t always the same bet.
Why Crypto Privacy Is Making a Comeback
Crypto privacy never really disappeared.
It just stopped being fashionable.
For years, the market became obsessed with DeFi, NFTs, memecoins, AI, RWAs and whatever narrative came next.
Meanwhile, blockchains kept becoming more transparent.
Analytics became better.
Wallet labeling improved.
Governments became better at tracing funds.
And more financial activity started moving onchain.
Eventually, those trends collide.
The more useful blockchains become, the more valuable privacy becomes.
That’s why I think the current privacy narrative is bigger than another Monero-versus-Zcash cycle.
Final Thoughts on Crypto Privacy
I’ve always liked Monero.
There’s something refreshingly simple about a cryptocurrency knowing exactly what it wants to be.
Private digital money.
Crypto Twitter might currently prefer Zcash as the privacy trade, and from a trader’s perspective I’m watching both.
But I’m even more interested in what happens outside those two coins.
The next generation of crypto privacy may look completely different.
Zero-knowledge proofs.
Confidential stablecoin transfers.
Selective disclosure.
Private DeFi.
Privacy-focused Layer 2 networks.
Encrypted blockchain applications.
And financial systems where transactions can be verified without everyone’s financial life becoming public information.
Crypto spent more than a decade proving that transparent financial infrastructure could work.
Now we’re discovering the obvious downside.
Most people don’t actually want transparent finances.
If trillions of dollars eventually move onchain, privacy won’t be a luxury feature.
It might become a requirement.
And that could make onchain privacy one of the most important crypto narratives of the next few years.

Crypto Privacy FAQ
What is crypto privacy?
Crypto privacy refers to technologies that limit how much information about your blockchain activity is publicly visible.
Most public blockchains are transparent by default. Wallet addresses, balances and transactions can often be viewed by anyone using a block explorer. Privacy technologies attempt to hide or selectively disclose information such as transaction amounts, wallet identities and transaction history.
Are cryptocurrency transactions anonymous?
Most cryptocurrency transactions are not truly anonymous.
Bitcoin and Ethereum are generally pseudonymous, meaning transactions are connected to wallet addresses rather than directly displaying your real name. However, if your identity becomes connected to an address, your previous and future blockchain activity may become easier to analyze.
This is one reason onchain privacy is becoming increasingly important as more financial activity moves onto public blockchains.
What are privacy coins?
Privacy coins are cryptocurrencies specifically designed to make transactions more private.
Monero and Zcash are two of the best-known examples.
Monero makes transaction privacy a core part of the network and hides information including senders, receivers and transaction amounts. Zcash uses zero-knowledge technology and supports shielded transactions that can conceal transaction details.
The two projects take different approaches, but both attempt to solve the transparency problem found on traditional public blockchains.
Is Monero more private than Bitcoin?
Yes. Monero was specifically designed to provide stronger transaction privacy than Bitcoin.
Bitcoin transactions are recorded on a transparent public ledger. Monero uses technologies including stealth addresses, ring signatures and confidential transactions to obscure transaction information.
However, no privacy technology should be treated as magical anonymity. Information outside the blockchain, such as exchange KYC records or a user’s own behavior, can still potentially reveal someone’s identity.
What is the difference between Monero and Zcash?
The biggest difference is their approach to privacy.
Monero makes privacy a default part of transactions. Zcash uses zero-knowledge proofs and supports shielded transactions that can hide transaction information while still allowing the network to verify that the transaction is valid.
Zcash also supports selective disclosure, which is particularly interesting for situations where someone wants financial privacy but may still need to provide information for auditing or compliance.
Both remain important projects in the crypto privacy sector.
What are zero-knowledge proofs in crypto?
A zero-knowledge proof allows someone to prove that information or a statement is valid without revealing all of the underlying information.
In crypto, this can potentially allow a blockchain to verify that a transaction is legitimate without publicly exposing every transaction detail.
Zero-knowledge technology is now being explored for much more than privacy coins. It can be used in payments, identity systems, DeFi, blockchain scaling and other applications where users need to prove something without revealing unnecessary data.
Why is onchain privacy important?
Onchain privacy becomes increasingly important as blockchains move beyond speculative trading.
Imagine receiving your salary, paying bills, holding investments and making everyday purchases using public blockchain addresses.
Without privacy, other people could potentially analyze parts of your financial history simply by following transactions onchain.
Businesses and financial institutions face similar problems. They may want the transparency and verifiability of blockchain technology without publicly exposing treasury balances, counterparties, payments or trading strategies.
Can crypto privacy and regulation coexist?
Potentially, and this could become one of the most important areas of blockchain development.
Crypto privacy doesn’t necessarily have to mean hiding everything from everyone.
Technologies such as zero-knowledge proofs and selective disclosure could allow users to keep financial information private while proving specific facts when necessary.
For example, someone could potentially prove they passed a compliance requirement without publishing their entire identity and transaction history onchain.
That middle ground between complete financial surveillance and complete anonymity could ultimately determine how crypto privacy develops.
