If ERC-20 balances and transfer amounts are encrypted by default, DeFi will still
Will it be like today?

This is the first thing that popped into my mind when testing @zama_fhe testnet
idea..

I remember a while ago I was chatting with an old friend in a cafe. He was the kind of guy who had just entered
DeFi newbies, their wallets are filled with various tokens, and they use the blockchain to calculate the amount of money they have.
As a result, one day he said proudly: "Brother, I
"I made a big trade on Uniswap, awesome!" I was delighted when I heard that and asked him:
"You're not using a coin mixer or anything, are you? The chain is completely transparent." He was stunned: "Transparent
It's okay to be transparent, no one knows me anyway."

But within two days, his girlfriend suddenly called him and said angrily: "You
What currency did you change in the middle of the night? I saw all the wallet records, and you're still hiding it.
Buy NFT?!" It turned out that Xiao Li's wallet address had been memorized by her.
I was browsing Etherscan and saw that he had secretly bought a "Romantic Surprise"
I wanted to give her the NFT of "喜" for Christmas, but it was exposed in advance.
Li was covered in dirt and dust. We were all laughing in the cafe, but he was also
I learned my lesson from that. I quickly created a Tornado Cash coin mixer and added
Now every time we meet, he pats me on the shoulder and says, "Brother
Brother, privacy is more important on the blockchain than in reality. You have to protect it like your own keys.
Protect your data just the same. Otherwise, your little secret will become street gossip one day."

In the past, Crypto’s privacy solutions were like a Swiss Army knife: ring signatures, coin mixing,
Pools, zk-SNARKs...all have complete functions, but users always have to find the switches themselves.
Zama's approach is to make the knife invisible.
Encryption (FHE) allows smart contracts to “see” data
In other words, the chain is still verifiable, but the data is readable by the naked eye.
The only information left is "a certain operation occurred at a certain address", amount, balance, voting rights
Re-emphasize confidentiality culture

The addition of @OpenZeppelin is equivalent to equipping this invisible knife with a standard
They jointly released Confidential Contracts v0.2.0,
Confidential balance, confidential voting, and confidential ownership locks are now available out of the box.
OpenZeppelin Style Library:

▰ Inherit ConfidentialERC20 to issue "encrypted" tokens
▰ Call ConfidentialVesting to hide the release curve during the entire lock-up period
▰ Using ConfidentialGovernor to vote, support rates are counted in real time, but no one can see the amount of each vote.

In a nutshell: Privacy is no longer an optional feature, but a templated and composable one.
The underlying module

Let me first talk about the background. Zama, a company that focuses on FHE technology, has already
In short, FHE is a kind of "lock box"
Calculation". The data is encrypted and thrown into the contract, and the contract can be directly in the locked box.
Zama's killer feature is
fhEVM, an EVM-compatible virtual machine, allows Ethereum developers to seamlessly
Access to cryptographic computing without having to learn cryptography from scratch. They are not doing closed
Garden, but open source everything, aiming for the mainnet launch in Q4, relying on ASIC chips
Pushing the film to tens of thousands of TPS

What about OpenZeppelin? The "security godfather" in the eyes of crypto developers.
Our contract library has protected $218 billion in assets, from ERC20 to governance models.
Over the past few years, they have audited numerous projects and helped
DeFi has avoided countless black holes. But OpenZeppelin also knows that security is not just about
Auditing is not enough, and privacy is the pain point. Everything on the chain is open, MEV robots,
Regulatory eyes, hacker snooping, all staring at your wallet.
It's like welding Zama's cryptographic engine into the OpenZeppelin logo.
Quasi-Curry

Putting the two together just fills in the missing piece of the other party:
OpenZeppelin has the trump card of "privacy", while Zama has the trump card of
A spacious developer traffic entrance. In the words of @randhindi, "the most credible
The "most trusted contract builder" shakes hands with the "most trusted confidentiality builder", which is quite
The security methodology of $200 billion of assets was transplanted to the encrypted digital currency at one time.
Data layer

The core of the cooperation is the new alliance Confidential Token Association
The three companies jointly launched the confidentiality token framework.
The balance is encrypted and the transfer is invisible.
The total supply and verification are still public.
Ruthless: Added confidentiality vesting (progressive unlocking), governance (encrypted investment
Voting) and checkpointing (state snapshots). Imagine a DAO voting
When you vote, the options are submitted in encrypted form and the results are published in decrypted form. No one knows who you voted for.
But the overall fairness and transparency. Technically, fhEVM allows Solidity developers to directly
Write encryption logic: encrypt data before entering the contract, calculate the entire ciphertext, and output
Select decryption. Compared with zero-knowledge proof (ZK), FHE is more flexible and does not require proof.
Circuit, just do the calculation. But the challenge is also great, the calculation cost is high, Zama
With GPU/FPGA optimization, TPS can now exceed 100, and will be even more powerful after the mainnet.

The impact of this cooperation goes far beyond a mere announcement. DeFi is now like a big square.
The transactions between the parties are clear and transparent, which is called "transparency", but it is actually a privacy killer.
The loan platform calculates your collateral rate, and you need to see your assets clearly; RWA (Real World Asset Value)
Assets) are put on the chain, and sensitive data is exposed at a glance. Zama + OpenZeppelin
Direct solution: Encrypted lending, institutions can be put on the chain without fear of leakage; sealed auction
Sell, bid without arbitrage; stable currency transfer, the amount is hidden.
What about gold? In the past, they thought the chain was too "naked", but now there is this,
Institutional funds such as BlackRock may also be willing to gradually test the waters

Some people say this is a "privacy revolution" that can attract trillions of institutional funds; others say
I am worried that FHE is too new and that audits may not keep up and something unexpected may happen.
Yes, there are risks, but OpenZeppelin's open source audit is a defense
Firewall. Compared to those meme coins that get rich overnight, the cooperation between the two is more like a slow
Beef stew. Large initial investment, strong momentum. Zama's test network has been launched.
Run, the creator plan rewards $50,000 per month to encourage everyone to build the ecosystem together

Ultimately, this isn’t just a Zama or OpenZeppelin show;
The upgrade of the entire chain. Privacy has changed from "icing on the cake" to "necessity", DeFi
Only then can it be truly popularized. Retail investors like me are happy to see it happen: take more paths, less
The risk of being exposed. What about you? Do you think this is too fake, or are you already brushing
Zama testnet?
