On a normal smart contract, data is simple.
If you send a number, the contract can:
⇒ read it
⇒ compare it
⇒ run calculations on it
Everything works directly because the value is visible.
That changes with encrypted data.
𝐄𝐧𝐜𝐫𝐲𝐩𝐭𝐞𝐝 𝐝𝐚𝐭𝐚 𝐢𝐬 𝐧𝐨𝐭 𝐫𝐞𝐚𝐝𝐚𝐛𝐥𝐞
Once a value is encrypted, the contract can’t see what it is.
It can’t tell if it’s 10 or 1,000.
From the contract’s point of view, it just receives something it can’t read.

In a regular contract, something like this is easy..
if value > threshold → do something
With encrypted data, that doesn’t work the same way.
The contract doesn’t know the value, so it can’t check it directly.

Instead of forcing the contract to deal with something it can’t read, @fhenix handles it differently.
When something needs to be worked on..
⇒ the contract sends a request
⇒ CoFHE handles the work
⇒ the result comes back
⇒ the contract continues
The contract does not need to see the actual number to continue.

In fhenix, the contract is no longer working with values it can read.
It works with:
⇒ encrypted inputs
⇒ results that come back
And it can still make decisions based on those results.

If the data had to be opened just to use it..
⇒ it would no longer be private
⇒ and the whole idea would be pointless
Fhenix avoids this by keeping the data hidden and handling the work separately.
𝐈𝐧 𝐬𝐢𝐦𝐩𝐥𝐞 𝐭𝐞𝐫𝐦𝐬
In fhenix, encrypted data stays hidden, but the contract can still use it.
The contract runs as expected.
It still makes decisions.
It works with the result without needing to see the actual value.
