# EPF - Week 2
## Study updates
Last week, I decided to shift my focus from based roll-ups to delve deeply into the topic of rainbow staking.
After watching Francesco's Zuberlin presentation, [Inclusion Lists with Francesco](https://streameth.org/zuberlin/watch?session=666960e207f92b086c2848bd) I decided to focus on inclusions lists.
## For fun
I explore this new smart contract language based on Rust
