 ## Introduction
 
-ML models like PyTorch's and Hugginngface's store model parameters (weight, architecture, etc) in several files stored in a directory. Models can be several hundreds gigabytes large. Thus we need a fast and flexible serizalization mechanism to cryptographically hash a model stored in a directory.
