Exploring and contrasting BitVM 1-of-N trust model
José Storopoli explores BitVM’s 1-of-N trust model for Bitcoin bridges, contrasting it with traditional federated multisig approaches. He explains key concepts like verified computation, Groth16 Bitcoin script compilation, and connector outputs for covenant emulation.

BitVM: How to bridge using 1-of-N trust assumptions
BitVM is a bridge between Bitcoin and a sidesystem. Generally, these bridges are secured by a federated multisig, where to bridge-out you need to have a majority of the federation. Mathematically, this is a (N2+1)(2N+1)-of-NN trust model. This is not ideal since it’s a “trust me bro” situation and the “bros” are the majority of the bridge. BitVM is different, since it can drastically reduce the trust assumptions. It is a 11-of-NN trust model, in which as long as you have one live honest operator, you can withdraw on-chain.
