# Ethereum cohort week 13

Updates:
- finalized correct implementation of pedersen hash in trie-key generation and tested against Ignacio test cases. https://github.com/Quadratic-Labs/VerkleTries_Besu/pull/43
- worked on the commitment in the trie, but still have issues with that, commitment in the trie is not returning correct results (tested against Ignacio's test cases)
- it's a bit unpleasant to hear other onlydust contibutors are considering moving to go-ipa JNI, since i invested some time into rust-verkle repo and making it work with Java, writing docs how to communicate Java<->rust.
- will probably try to make more progress on the verkle tries in-circuit given the situation with development of this lib
