gberry fam 🍓
yesterday one of the dopest updates dropped
@build_on_bob just bacome the first hybrid zk rollup
partnered up with @boundless_xyz 

BOB is been one of my fav projects since day X
so this hit diff for me 😊

what's a hybrid zk rollup?
we've got X main types:
→ optimistic rollups: assume txs are valid unless challenged (but 7D wait if they are)
→ zk rollup: every tx proven from the jump

BOB blends both
moves smart between the two models
using zk when needed

and boundless makes zk proving dead simple, cheap and fast.
it handles the zk fraud proofs, and when fast withrawals needed.

mad respect for BOB
they didn't pick a side
they fused the best of both
