# Update 7 ## week 7 updates * this week I mostly focused of reading ethereumJS codebase and it's implementation of stateless-client: * ethereumJS uses the rust-verkle cryptography compiled into wasm in this repository: https://github.com/ethereumjs/verkle-cryptography-wasm * which is then imported in the ethereumjs monorepo as javascript. The two main sections of code where the verkle cryptography is used are: * the verkle package: https://github.com/ethereumjs/ethereumjs-monorepo/tree/master/packages/verkle * the verkle file in the util package: https://github.com/ethereumjs/ethereumjs-monorepo/blob/master/packages/util/src/verkle.ts * `VerkleStatelessStateManager ` provides an overview of how this components are used: https://github.com/ethereumjs/ethereumjs-monorepo/blob/master/packages/statemanager/src/statelessVerkleStateManager.ts ## week 8 roadmap * look into geth implementation of verkle-trie and EL changes * prepare a design doc for reth's implementation
