How do we interact with Bitcoin in a multi layer world? What cost savings and trade offs are necessary here? What even counts as a layer? Kilian from boltz.exchange joins me to talk about swapping across Bitcoin on-chain, Lightning and Liquid. We discuss:
- How swapping works
- What makes it atomic and non-custodial
- What counts as layer 2
- Fee savings and trade offs
