notes on canonicalization, dag traversal order

@jbenet i’ll do a pass on canonicalization for the car format, but one thing i’m thinking through right now is that you can’t just naively CAR things up and store them in a sector.

For example if you tried to store the filecoin blockchain this way, it would include all the state trees, and even (depending on a few things) all the data in the network

my question about traversal order is because we need to be able to have a specific traversal order to ensure CAR files are deterministically generated

so the thing being referenced needs to be a selector

@hannahhoward Does the ipld selectors work strictly define graph traversal order?
