# EPF5 Dev Updates - Week 5

## Goals Accomplished this week

- [x] Completed project proposal and presentation slides.
- [x] Implemented cryptography on my [local repository](https://github.com/gerceboss/cryptography) and made branch on my local fork of Constantine.
- [x] Working on `PolynomialCoef` related functions 


During the next week I plan to write the unit tests using the [consensus test vectors](https://github.com/ethereum/consensus-spec-tests/tree/v1.5.0-alpha.2/tests/general/eip7594/kzg) as data for the tests. Other than that, I will try to write something about Lagrange interpolation and KZG commitments.

I listened to [PeerDAS breakout room](https://github.com/ethereum/pm/issues/1093) where there was discussion regarding updating the consensus specs to include https://github.com/ethereum/consensus-specs/pull/3832

## Plan For Next Week
 
1. Complete the [helper](https://github.com/ethereum/consensus-specs/blob/dev/specs/_features/eip7594/polynomial-commitments-sampling.md#polynomials-in-coefficient-form) functions and tests I mentioned above and make a PR.
2. Listen to breakout room for updates on testing of peerDAS.
