Module Make.DalSource
A precomputed set of constants
Parameters to build a value of type t
An encoding for values of type parameters.
make precomputes the set of values needed by cryptographic primitives defined in this module and store them in a value of type t
parameters t returns the parameters given when t was initialised with the function make
Commitment to a polynomial.
A proof that the polynomial associated to some commitment is bounded by a constant.
verify_commitment srs commitment proof checks whether commitment is a valid commitment. In particular, it check that the size of the data committed via commitment do not exceed C.slot_size. The verification time is constant.
The original slot can be split into a list of pages of fixed size. This size is given by the parameter page_size given to the function make.
A proof that the evaluation of points of a polynomial is part of a commitment.
An encoding for the proof of a page.
pages_per_slot t returns the number of expected pages per slot.

(bool, [> `Segment_index_out_of_range | `Page_length_mismatch ]) Result.tverify_page t srs commitment page page_proof returns Ok true if the proof certifies that the slot_page is indeed included in the slot committed with commitment commitment. Returns Ok false otherwise.
Fails if the index of the page is out of range or if the page is not of the expected length page_size given for the initialisation of t.
