Episode notes
Why Lattices?
- Lattice-based SNARKs offer potential post-quantum security and performance benefits.
- They also enable verifiable FHE computations and new folding schemes.
FHE and Lattices
- Lattice encryption's fast decryption enables bootstrapping and FHE.
- Current FHE constructions might not be optimal, other approaches could exist.
Greyhound Performance
- Greyhound, a lattice-based polynomial commitment scheme, allows commitments to large polynomials.
- For a billion-degree polynomial, proofs are ~53KB and verify in ~2 seconds.
