# Update 8
## week 7 updates
* this week I connected with my mentors from the reth team, and finalized this proposal: [reth-verkle PoC](https://hackmd.io/@adigupta/r1l259oFC)
* after that I started reading code of go-verkle.
* looked after the implementation in geth:
* geth has all the proving mechanisms in place, that is getting the witness data, then for the provided stateDiffs construction of pre-state trie and verifying the correctness of given witness data against our trusted pre-state root.
* but witness construction during execution and block execution using witness as `stateDB` is yet to be implemented.
## week 9 roadmap
* this week will focus on exploring banderwagon and IPA implementation in rust-verkle and go-verkle
* and exploring nethermind implementation
