# Update 12

## week 12 updates
This week I focused mostly on Zk-friendliness of verkle tries, tried to benchmark various approaches, and what would be better, Zk-Friendly hash functions for example if we use [the method of GKR](https://ethresear.ch/t/using-gkr-inside-a-snark-to-reduce-the-cost-of-hash-verification-down-to-3-constraints/7550) to reduce the cost of hash function inside a SNARK or elliptc curve based SNARK, most of the week was spent in this only.
