# EPF-5 | Week 4
This week I deep dived into the second project I selected for the fellowship: C bindings for constantine particularly Verkle trie implementation (proposed by Nimbus). Followed the following:

* https://github.com/mratsim/constantine/blob/master/constantine/ethereum_verkle_ipa.nim
* https://ihagopian.com/posts/anatomy-of-a-verkle-proof
In addition to this got in touch with @manulp regarding suggestions for my proposal for the libP2P project.
## Future Roadmap
Next two weeks I will majorly spend my time in finalising the proposals.
