Zama's HPU is the most 'non gimmicky' privacy hardware I have ever seen
A few days ago, I saw someone in a closed Builder group post a sentence:
Zama's HPU has started running, and stablecoin transfers can reach up to 230 TPS. ”
My first reaction was: Is it really fake? Isn't FHE jumping in just a few tens of milliseconds?
Then I went to check the official Twitter account and found out that the entire HPU stack is completely open source, with code available on GitHub. Friends who understand technology can go take a look
What is HPU?
@Zama_he made a piece of hardware - yes, real hardware, it's the one in the tweet. Not a white paper - specifically designed to accelerate FHE computation, just like how GPUs unlock AI, HPU is helping FHE encrypt computation by "breaking the shell".
And it's said to be open-source, running on FPGA, PCIe can be plugged in and tested
What can it do? I have summarized the following points for everyone:
⚙️ Hardware level key switching (previously required CPU to slowly calculate)
⚡ Programmable bootstrapping, latency<1ms
Optimized 4-digit ciphertext operation for blockchain scenarios
Can directly interface with TFHE rs backend
The encryption logic that you used to be able to run on the CPU can now run dozens of times faster without losing any privacy.
To be honest, ZK is still working on proving the circuit, while Zama's HPU has already run encrypted transfers on the chain.
Even more exaggerated is that you can write the code now to try it out.
GitHub code is fully open source
The demonstration video shows the real-time running process on FPGA
Is the document the kind that deceives people? Those who have tested it can provide feedback
But I think such a bold push would probably take you a few minutes to test this thing if you install it on your computer.
Why do I think this thing is important even though I don't understand technology?
DeFi can no longer rely solely on "transparent contracts+transparent data", it can now be kept confidential and run smoothly
AI reasoning can be encrypted and executed (paired with their Concrete ML)
The key is that developers no longer have to choose between privacy and performance
Zama gave a third path: both should be taken, performance should also be taken, and privacy should not be compromised.
They have FHEVM (Solidity writes confidentiality agreement)
There is TFHE rs (Core Password Repository)
Now there is HPU (Acceleration Hardware)
It's not just storytelling, it's building the Infra layer by layer.
Looking forward to @ randhindi bringing more sharing.
By 2029, when they go on ASIC, if they really achieve 100000 TPS, it may be more than just 'Visa' on the chain.
