# Han (weihan) - Update 7

## Summary
I've mostly spent my time on the design specification and creating the rough template on setting up a local private network.

## Design Specs
I've finished writing the design specification for this project, which includes the rough design of a few major components such as state epoch metadata, verkle tree, state storage, EVM and pruning.

Check it out [here](https://hackmd.io/0iv3GXdWQ7ed5fdhKPL2aA?view).

## Local Private Network 
I've briefly setup a repository to test out the state expiry scheme. I'm using Clique consensus (PoA) as it's easy to setup. I will testing on a few scenarios such as submitting regular ETH transfers and ERC20 transfers and test out the expiry feature.

Check out the repository [here](https://github.com/weiihann/verkle-state-expiry).
