# Updates: ## Hashing - Added SpongeHasher class - Can be used to accept any hash function as an argument - Absorb and squeeze are now separated - Memory management is now mostly done by SpongeHasher class, each hash function only describes permutation kernels ## Tree builder - Tree builder is now hash-agnostic. - Tree builder now supports 2D input (matrices) - Tree builder can now use two different hash functions for layer 0 and compression layers ## Poseidon1 - Interface changed to classes - Now allows for any alpha - Now allows passing constants not in a single vector - Now allows for any domain tag - Constants are now released upon going out of scope - Rust wrappers changed to Poseidon struct ## Poseidon2 - Interface changed to classes - Constants are now released upon going out of scope - Rust wrappers changed to Poseidon2 struct ## Keccak - Added Keccak class which inherits SpongeHasher - Now doesn't use gpu registers for storing states To do: - [x] Update poseidon1 golang bindings - [x] Update poseidon1 examples - [x] Fix poseidon2 cuda test - [x] Fix poseidon2 merkle tree builder test - [x] Update keccak class with new design - [x] Update keccak test - [x] Check keccak correctness - [x] Update tree builder rust wrappers - [x] Leave doc comments Future work: - [ ] Add keccak merkle tree builder externs - [ ] Add keccak rust tree builder wrappers - [ ] Write docs - [ ] Add example - [ ] Fix device output for tree builder --------- Co-authored-by: Jeremy Felder <jeremy.felder1@gmail.com> Co-authored-by: nonam3e <71525212+nonam3e@users.noreply.github.com>
