Clementine: A Collateral-Efficient, Trust-Minimized, and Scalable Bitcoin Bridge
Notably, Clementine features crucial improvements when compared to state-of-the-art protocols such as BitVM Bridge [14]. First, Clementine runs the first provably secure Bitcoin light client on Bitcoin, achieving resilience against an adversary with less than 50% of the computational power in the presence of a permissioned set of watchtowers, of which at least one is assumed to be honest
