If crypto really wants to onboard the next billion users – it has to fix one uncomfortable truth:
Right now, everything onchain is public by default.
Your wallet balance. Your transaction history. Your DeFi positions. Your token trades. Your payroll.
Anyone can see ALL of it.
For early crypto users, that might’ve felt like great transparency.
But for normal people, businesses, banks, and governments – it’s wildly unsafe. And it’s the single biggest reason real-world finance hasn’t fully moved onchain yet.
This is where Zama comes in.
Zama is building something they’ve dubbed “HTTPS for blockchains.”
It’s aiming to be the confidentiality layer that finally upgrades crypto from “everything is public” to “encrypted by default.”
And it might be the most important infrastructure shift crypto has seen since smart contracts.
Crypto Is Still Running on the Old, Unencrypted Internet
To understand why this all matters, it might help to rewind and take a look at the OG internet.
The early web ran on HTTP – plain text.
Everything traveled across the internet fully exposed. Anyone watching your connection could see what you typed, clicked, or bought. It worked… but it wasn’t safe.
Then HTTPS came along.
Suddenly, the web became encrypted by default. A single upgrade unlocked online banking, shopping, private messaging, and everything we take for granted now.
The thing is, crypto hasn’t made that jump yet.
Blockchains today still behave like HTTP.
Anyone can look up anyone’s crypto address and instantly see balances, activity, and a complete history of transactions.
If you’ve ever copied a wallet address into a block explorer, you’ve seen exactly how exposed everything is.
For example, check out Vitalik’s wallet right here:
That kind of transparency might be fine for memecoin traders.
But it’s not fine for:
- Banks settling trades
- Companies running payroll
- Funds managing billions
- Governments issuing bonds
- Merchants taking payments
You kinda get the picture.
In traditional finance, asking someone to show you their bank account is rude and invasive. Onchain, it’s unfortunately built into the system by default.
And that’s the bottleneck holding crypto back from full-scale adoption.
Privacy Is No Longer a “Nice-to-Have”
For years, privacy in crypto kinda lived in a weird corner of the market.
Privacy coins, mixers, and other shielding tools – it’s all had a sketchy rep.
But today, that tone has changed.
Institutions now openly say that confidentiality is a requirement, not a feature.
“Public blockchains are powerful – but sometimes too transparent. Few corporates want supplier terms, pricing, or payroll data visible on a public ledger.” – Citigroup
Moving serious money through systems where anyone can see every single transaction, forever? Not gonna happen.
Don’t get me wrong, crypto is off to a great start.
Stablecoins are already doing monster numbers in volume. We’re tokenizing more and more real-world assets. Governments are looking at onchain rails.
It’s just that none of this can survive long-term without privacy.
The world is finally realizing crypto isn’t just about speculation anymore.
But it’s missing infrastructure.
What Zama Is Actually Building
So…now onto how Zama is actually making this reality come to life.
Their big idea is actually quite simple to explain, (even if it’s insanely hard to build):
Zama wants to add privacy directly to existing public blockchains – without breaking how apps work, or changing anything for users.
And that’s NOT through a new privacy chain, side network, or something you’ve gotta bridge into.
It’s a privacy upgrade layer that works on Ethereum and other major chains.
What does that mean?
It means you get the same wallets, the same smart contracts, and the same DeFi building blocks…
But it's all private.
Your balances and transaction amounts stay hidden, but everything still works like normal.
Keeping the internet analogy going, they call this vision “HTTPZ” – the encrypted-by-default version of crypto.
“FHE” – The Secret Sauce Behind Zama’s Privacy Tech
The magic behind Zama is something called Fully Homomorphic Encryption, or “FHE” for short.
Sound complicated? It is.
But here’s an easy way to understand it:
FHE lets computers work with secret (encrypted) data – all without ever seeing it.
It means a smart contract can handle money, run logic, and make decisions…all while the real numbers stay hidden.
For decades, FHE was considered just theoretical.
It worked on paper, but it was too slow, too complex, and too expensive to run in real systems.
But Zama has spent the last five years changing that.
Today, their FHE stack is:
- Fast enough for production apps
- Able to works with familiar languages like Solidity
- Quantum-proof
- Able to runs computations in milliseconds
- Inexpensive, costing fractions of a cent per transaction
It’s no longer science fiction – it’s real infrastructure.
Why Zama Uses FHE, MPC, and ZK Together
Ok I get it, that’s a lot of acronyms.
But all you need to understand is that they’re all privacy and security tech – and Zama’s rolled them all into one system.
This hybrid system uses three cryptographic tools, each for what it does best:
- Fully Homomorphic Encryption (FHE) lets you run calculations on data without unlocking or exposing it.
- Multi-Party Computation (MPC) spreads sensitive keys across multiple parties so no one person can see or control them alone.
- Zero-Knowledge Proofs (ZK) let you prove something is legit without showing the actual data.
Together, this gives you:
- Balances stay private
- Transfers stay private
- Rules still work
- Anyone can verify it
- No one entity controls it
- No single key can unlock everything.
You get crazy good privacy, without sacrificing decentralization or how well apps work.
What Can You Actually Do With This?
The biggest and most obvious use case is simple:
Private stablecoins on Ethereum.
You can move stablecoins on public blockchains, but balances and transfer amounts stay hidden.
Now, you can pay salaries without exposing everyone’s income.
You can take payments without putting your business on display.
You can manage company funds without revealing wallet activity.
Nobody’s going to be able to front-run your trades, and you can do accounting without everything being public.
And that’s only the tip of the iceberg.
Confidentiality Fixes DeFi
DeFi today has two big problems.
- Everything is public. Anyone can see how much you have, what strategies you’re running, and when you’re close to getting liquidated.
- Bots are always watching. They jump ahead of trades, squeeze orders, and quietly drain value from normal users.
Confidential DeFi changes that.
With encrypted computation, trade sizes stay hidden, positions aren’t exposed, liquidation points aren’t going to give you away, and front running becomes much harder.
All that makes new things possible.
- Private lending
- Hidden options markets
- Credit scoring without exposing wallets
- Onchain finance that institutions can actually use
It also makes onchain finance usable for institutions that don’t want all their activity visible to the public.
Real-World Assets Can’t Go OnChain Without Privacy
Tokenizing real-world assets is one of crypto’s biggest ideas right now.
That covers things like stocks, bonds, funds, treasuries, carbon credits, and private equity.
The tech already exists to do this, but the problem is visibility. Public blockchains show everything, and that doesn’t work for real finance.
Institutions can’t operate if everyone can see who owns what, how positions are structured, how trades are executed, or how compliance is handled.
Zama makes it possible to run these assets on public blockchains while keeping ownership and sensitive data private.
The best part for compliance is that rules like KYC and AML can still be enforced – just without giving up personal or business information.
And that’s what will actually connect traditional finance to DeFi.
Privacy Unlocks a Whole New Class of Apps
Once blockchains can handle private data properly, a lot more becomes possible.
You can finally have onchain identity without putting personal details on display.
Personal information stays private, governance systems can work without being influenced or pressured, and auctions aren’t easily manipulated by bots.
Token launches and vesting schedules can happen without telling the world about everyone’s allocations, and prediction markets can work without obvious bias leaking into the system.
We might even start seeing the idea of fully onchain companies – with private cap tables, private payroll, and private board decisions.
Blockchains will stop feeling like a financial experiment, and start acting like real-world infrastructure.
Private Transactions Without Slowing Ethereum
Ethereum isn’t built to run heavy encrypted computations.
And doing that kind of work directly onchain would be slow and expensive.
Zama gets around this with a smart setup.
When a private smart contract runs, Ethereum doesn’t do the heavy encrypted math itself.
Instead, it sends a signal so that specialized FHE computers can handle the calculation off-chain.
They then send the result back, in a way anyone can verify.
The result is that it’s fast and it all stays encrypted – but it can still be used by other contracts, and doesn’t leak any private information.
When something needs to be revealed, the key is split across multiple independent operators.
A value only gets unlocked if the contract allows it – and no single party can unlock it by themselves.
That means getting privacy, without having to trust anyone individually.
The $ZAMA Token
The Zama Protocol runs as a decentralized network, not a company-controlled service.
To help it operate, it uses its own token – $ZAMA
$ZAMA is used for:
- Paying for transactions (“gas” fees)
- Staking by operators
- Voting on upgrades or rule changes.
Any time the network does something encrypted – checking results, unlocking values when allowed, or moving data between chains – $ZAMA gets used behind the scenes.
What I thought was cool was that fees are set in dollars but paid in $ZAMA.
That means costs stay predictable, even while the $ZAMA’s value stays tied to how much the network is actually used.
Most users won’t ever have to think about the token at all – apps can handle it for you, the same way wallets handle gas today.
How Cheap Is Confidential Crypto Today?
Right now, private transactions are already pretty affordable.
A fully private token transfer usually costs anywhere from under a cent to around 80 cents, depending on how much volume you’re doing.
Apps that run a lot of transactions can get that cost down to well below a cent each.
In terms of speed, Zama can handle about 20 transactions per second on regular CPUs today.
With GPUs, that jumps to hundreds per second.
And with purpose-built hardware, the goal is to reach well over 100,000 transactions per second.
At this point, the main bottleneck isn’t the cryptography anymore – it’s the hardware running it.
Security and Compliance Are Built-In.
Zama was designed with security in mind from start to finish.
Here’s a summary of each part, written in plain language (and tech-speak in brackets!).
- Long-term secure encryption (post-quantum FHE)
- Keys split across many operators (MPC, with a 13-node threshold)
- Secure hardware for critical steps (enclaves)
- Publicly verifiable encrypted computation (verifiable FHE)
- Penalties for bad behavior (slashing)
- Independently audited by Trail of Bits and Zenith.
On the compliance side, Zama doesn’t force rules onto users.
Instead, it lets developers build things like KYC or access rules directly into smart contracts, while the underlying protocol stays neutral.
That’s what makes it kind of a strange combo:
It protects user privacy, but still works in places where regulators need guarantees.
Why This Is All Happening Now
Privacy isn’t coming back because crypto ran out of new ideas – it’s coming back because the ecosystem is changing.
Stablecoin usage is taking off, real-world assets are actually being tokenized, and institutions are starting to move onchain.
And, for the first time, the tech needed to make privacy work at scale is finally fast enough.
At the same time, Zama isn’t some brand-new experiment.
They’ve raised over $150 million at a $1 billion valuation, with backing from people who helped build Ethereum, Solana, Filecoin, and Polygon.
They also run the world’s largest dedicated FHE research team, and thousands of developers already use their tools.
This isn’t a test run – it’s the real rollout of confidential computing for crypto.
The Token Launch Is the Starting Gun
Zama isn’t launching as a feature or a product.
It’s launching as a fully decentralized protocol, with its own operators, staking, governance, and incentives built in from day one.
The token launch is what flips the switch.
That’s going to be the moment Zama moves from being a tech provider to becoming a decentralized network that anyone can participate in.
The Bigger Picture
Crypto already showed it can move money.
But what it hasn’t shown is that it can protect it.
Privacy is the missing layer – and Zama isn’t talking about it, they’ve built it.
This is the shift from public to confidential, from experiments to real infrastructure. Just like the web had to move from HTTP to HTTPS, crypto has to move behind encryption.
If blockchains are going to support real payments, real markets, real businesses, and real institutions, they can’t run in public.
That’s what Zama is enabling – and that’s why it matters.
