here is what killed every previous attempt at fully homomorphic encryption (fhe): noise accumulation.
when you encrypt data, you’re essentially hiding the real value inside statistical noise. every computation you perform - addition, multiplication, comparison - adds more noise. after a few operations, the noise drowns out the signal completely. your encrypted answer becomes mathematically indistinguishable.
you could technically compute anything on encrypted data, but you’d wait weeks for results a normal computer delivers in microseconds.
zama’s tfhe (torus fully homomorphic encryption) scheme inverts this entire paradigm.
