Many people try to push a narrative that it’s FHE against TEE, MPC or ZK. This is wrong for 2 reasons:

People often ask what is the difference between FHE and Tornado-like privacy. A good analogy is that Tornado is like Tor: the content is public, but your identity is hidden. In other words, the data is public, but the metadata is private. FHE on the other hand is more like

The solution is homomorphic encryption! Send encrypted queries, receive encrypted response. Same service for you, but OpenAI no longer sees the data.
Italy banned ChatGPT b/c it is unclear what OpenAI does with all the data it collects - that you enter! No one knows.
The EU regulator believes you should have the right to know what happens to your data & the right to later remove it, if you want to. You cannot, with ChatGPT.

FHE is the holy grail of cryptography. It allows computing on encrypted data, without having to ever see it. This removed all issues of confidentiality, data leaks, surveillance, while also enabling novel use cases.

So here is our masterplan:
- first, make FHE available to every developer
- second, make FHE fast enough to do 1000 tps in blockchain and run LLMs encrypted end-to-end
- third, extend it to all web services
- finally, make the internet encrypted end-to-end via an HTTPZ protocol

The reason FHE is so great for blockchain is that it enables composability on encrypted states. FHE smart contracts compute on encrypted data instead of public data, but otherwise are exactly the same as regular contracts, written in plain Solidity.
