Brollup

Brollup is a rollup designed for scalable, Bitcoin-native smart contracts. A 'true' layer two with unilateral exit, Brollup ensures users retain full custody of their funds while rollup operators solely provide the service. No trusted setup. No 1-of-n trust assumption.

Brollup utilizes Bitcoin block space for data availability and incorporates a state channel model with global state. Operating in a layer-two setting, Brollup supports unilateral exit and does not rely on any trust assumptions.

Brollup is in a category of their own, neither optimistic, ZKP, nor sovereign.
