# EPF Week 4 and 5 Gm everyone! I am working on writing and improving the tests for the Verkle Trees library for the Nimbus and Besu client. Deep dived in [tree.go](https://github.com/gballet/go-verkle/blob/master/tree_test.go), [tree_test.go](https://github.com/gballet/go-verkle/blob/master/tree_test.go). Assigned myself this [issue](https://github.com/status-im/nim-eth-verkle/issues/6) to write similar tests for nimbus verkle trie. I assigned myself this [issue](https://github.com/Quadratic-Labs/VerkleTries_Besu/issues/12) to write tests for Pederson Commitments and Update Commitments in Java. Will be mainly working on completing this for the coming week. ## Weekly Meetings Update ### Nimbus Client Discussed weekly updates. Asked Mamy some questions from the constatine library, a constant-time crypto library in Nim. Setup the nim-eth-verkle repo with Danial and Zahary's help. ### Besu Client Had a great discussion with Karim from Besu and other people. Karim walked through some bits of the Bonsai codebase and how data is stored in it.
