Followed the following: * https://verkle.info/#block-332fc5e880bc452d96477abac0a2f164 * 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.
